[@billietyree6139]

I spent the summer of 1951 working as a coal passer on an iron oar boat on the Great lakes. This ship was built in 1914 and used coal to power to generate steam for her three cylinder, three phase steam engine. We worked 4 hours on and 8 hours off. My job was to get the coal from the bunker down to the fireman, shovel ashes into the Ash Gun, a steam powered venturi in the bottom of a hopper, which shot the ashes up and out the side of the ship, and to run around and pull the proper chains which turned the wheels that moved a steam nozzle over the flues in the furnace and blew out the soot into the ships funnel. We were rightly called 'the black gang'. it was a filthy and unhealthy job that was a lot of fun for a young man. We made regular runs from Duluth or Escanaba to Gary, Detroit or Conneaut.

[@NofaKingway]

Sadly the automatic ash ejector was removed from our vessel. We have to pass the ash buckets into an ash hoist installed in the port side ventilator shaft, haul them up. Thankfully, as a historic vessel we only generate enough ash to warrant cleaning once a week - or three days of sailing having burned 8t coal. 8t Would have been a typical shift in her service life.

[@andymunns2579]

Great video - Another big improvement with oil fuel was the removal of the need to clean the fires - Cleaning fires of clinker and ash happened to each furnace as frequently as once per shift if the coal was bad. This would take say 15 minutes and the firedoor would be letting in cold air during this time. The firebed also had to be rebuilt with fresh coal afterwards and it would be another 20+ minutes before the furnace was well alight. Oil fired furnaces did not need this regular cleaning, and as well, there was less soot to clean out. The downside was that oil soot was blacker and stickier...

@@MicahtheDrumCorpsPseudoboomer Three methods - Some ships like Titanic had a dump bin in the bottom of the hull - Firemen could shovel the tons of ash generated each watch into a hopper - A water tight lid was closed and bottom doors opened. Other ships had a Sees ash ejector, which was like a big cast iron toilet - Ash was shoveled into the hopper and a high pressure jet of seawater blew the ash overboard from an opening just above the water line. Others had an ash hoist that pulled buckets of ash up to deck level where the crew manhandled the ash overboard.

Let's not forget that there was a smoldering coal fire in one of the bunkers that had started 10 days prior to the inaugural passenger run of the Titanic. Which probably played more of a role in the ship actually sinking, than just an iceberg strike alone.

[@ЛАДАРРО]

[@robertschultz6922]

There is huge debate as to the exact extent the fire had on the sinking. It's been overly sited.

[@PeterJ-de4wk]

Fantastic video! I would just add two points in regard to efficiency. The accumulated saving in fuel with oil burners, is that changes in steam demand, are met almost immediately with a reduction in oil flow to the atomisers. With coal firing, you need to know in advance if the engine speed is going to be reduced or stopped, otherwise you have large amounts of coal already burning in the furnace going to waste, and the result is that boiler pressure exceeds the limit of their design, and the safety valves blow off wasting precious fresh water too. Of course the same is true if demand increases. You need more coal burning ahead of time to meet demand. With oil, you just open up the valves. The second point, is that of draughting. Coal requires primary air to be drawn through the fire to burn properly and with maximum heat and efficiency, and unlike a railway locomotive, their is no steam exhaust blast up the funnel inducing a draught on the fire, as on a ship, the steam is in a closed cycle, i.e. Reused in a continuous loop. Some different methods were used in coal burning ships, including partially pressurising the boiler rooms, stokers and all. There is no need with oil burners as the oil is, in effect sprayed into a mist by the atomisers, providing enough continuous pressure for combustion and naturally drawing in the rest.

[@TheGreatBigMove]

Thanks for the additional detail! I might one day do a video on raising steam and managing the boilers, etc. throughout a voyage.

[@myparceltape1169]

Yes, raising steam before needing it was still necessary, for ships and steam powered railway locos. At the end of the journey they would know how soon to turn off the burners before they weren't needed. On a coal fired loco the firemen could actually drop the burning coals in the pit below the engine if he had miscalculated, but this practice was frowned upon.

[@ThePeachJames]

Nope. Forced draft on oil boilers is needed as well- you have to think that if you are burning say, 7050 lb/hr of fuel per boiler, you need 7050*14=98 000 lb of combustion air, or about 1.3 million cubic feet of air per hour. (so 22 000 cubic feet per minute of combustion air). We ran at up to 25-28 inches of water of air pressure for the boiler casings, with the boilers being surrounded by the casings and the boiler room generally running at about .3-.5" WC in comparison to the engine room & ship interior. 200 HP per side for the FD fans :). (& 15 HP for the fuel oil pumps, and 70 lb/burner/hr of steam for atomizing steam...).

I worked as a Process Operator at a refinery for 13 years, running the destillation unit and all related utilities such as the boilers. The oldest boiler we had was from 1928 xD Anyway, depending on what oil you use, and how pure the coal is, by *weight* oil has around 10-15 times as much potential energy compared to coal. Coal being all lumpy also has a worse packing-coefficient, meaning there's air between the lumps. Something that doesn't happen to oil. Keeping in mind that I'm talking about modern fuel oils here, not *any* oil. I have no idea what quality of oil was used on ocean liners, nor the related costs and its transport chain. I can only compare modern oil to coal, but for those of you who are interested in a closer look, here it is :D Another quick point: all dust can explode. Coal-dust is very dangerous and unpleasant on more levels than just causing black-lung. Oil is safer. Not *safe.* It's sensitive to getting statically charged from a certain free-fall height (on the refinery I worked at, we never let oil free-fall more than 1.5 meters (whatever the hell that is in american made-up measurements, you'll have to do some maths). But it's still safer than coal in many, many ways.

[@morg777]

Most fuel oil in ships was (and is) bunker C, so bottom of the barrel stuff. And you're right, it's much safer than coal firing. Coal dust fires and explosions were fairly regular occurrences back in the day, and in fact may be the real reason the USS Maine blew up in Havana in 1898. As far as the made up measurements, we were just using what the British gave us way back when. Though with all the international work I've done, I can easily work with either.

[@ThePeachJames]

Check your math- #6 (aka Bunker C) has listed as 152400 btu/gal, so about 19050 btu/lb. Coal is dependent on seam- harder coals have higher btu/lb, at up to about 13700 btu/lb. Packing density is definitely an advantage- as a ton of coal is often quoted as 42 cubic feet, which would be about 2x that of fuel oil. (1 CuM of F76 (Diesel) = 820 kg, in metric...) There are many reasons why the majority of steam ships post 1910 were oil fired...ship owners were a canny lot, and if it didn't pay, they'd have carried on burning coal as SS Badger does still.

[@srfurley]

Given the need to heat the heavy oil, how did they fire up the boilers? Did they start them on a lighter grade of oil which didn’t need heating, or have a small boiler fired on some other fuel to provide a steam supply for this purpose. I know that this was done at a coal fired power station which I visited where the heavy oil used to start up the boilers had to be heated by a small boiler at the unloading point to enable it to be pumped to the storage tanks. Presumably it would also have to be heated when pumped from those tanks to the main boilers. That power station used many fuels, as well as the main fuel, coal, it also needed the heavy oil for starting up, light oil for various vehicles and for four gas turbine sets and two small emergency Diesel generators and there were two large tanks of propane, I’m not sure what that was used for. Later three of the four main boilers were converted to also be able to burn natural gas, and a S mall amount of biomass was also fired. The amount of ancillary plant required to operate that station was incredible compared with a modern gas fired combined cycle gas turbine station.

[@Zeppflyer]

Great video! I'd been wondering about this subject and specifically the reduction in manpower. On warships, the significant downsides to oil were that coal served as ersatz armor (something like 8-10 inches of coal = 1 inch of steel) and the lack of infrastructure in place in some areas to store and handle oil. Did civilian shipping companies experience any direct downsides aside from cost and the social impact that you mentioned? Perhaps in terms of logistics? How long did it take for oil infrastructure to reach smaller ports around the world?

[@zachogdahl210]

The beautiful thing about bunker c is that it is made up of the leftovers from refined oils. These leftovers were typically disposed of but ships and shoreside plants would end up burning it. Ships still use it today however its not good for the environment so regulations state that the ships need to switch to regular diesel before coming in to port. This has the advantage of cleaning the fuel system out before entering port where majority of the maintenance is done.

[@freddieellis8449]

Drachinifel also does a great long-form video on naval boilers, both coal and oil. Not to disparage this one whatsoever, as it is equally as fascinating! 👍🏻😇 One disadvantage to conversion for warships was that the sheer bulk of coal gave some extra resistance to shell penetrations. Not a massive increase but it did provide a slight increase in protection.

[@michaelbujaki2462]

On the railways, it was still just as good to use coal because a coal tender could be loaded in seconds instead of minutes.

[@morg777]

Like so many things in life, it depends on the railroad and what was easily and cheaply available. In the western half of the United States, coal deposits were scarce and of low quality, certainly not the good anthracite or bituminous that was plentiful back east. Many railroads like the Southern Pacific and the Santa Fe ran almost exclusively with oil burning steam engines because oil was available at a lower cost to these railroads than having to ship coal from the east.

[@phantomsoldier497]

It depended on environmental problems as well. Many places limited coal fired trains to avoid forest fires to cinders and soot pollution in cities

If marine boilers behave similarly to land based boilers, you can generally achieve a higher firing rate, and therefore a higher output on oil than you can with hand fired coal. I have done several conversions of hand fired coal boilers to oil/gas, and the published rating was usually about 5-10% higher for oil firing than the anthracite coal muzzle loader rating.

Back in Newfoundland during my College days, Corner Brook had a big 2 foot diameter heated Bunker C pipeline from the big field of tanks to the pulp and paper mill, in the middle of winter we would drink beers on the pipeline, it was always warm up there!!!!!

would be nice a video on lng (liquid natural gas) powered ships, cause it seems it's the next big move in ocean liners. some ships are already operting on nat gas, i.e. costa smeralda!

[@lewisdoherty7621]

I help maintain a 1921 oil-fired standard gauge steam locomotive. Comparing our activity to the coal locomotives and their maintenance schedules, I also think there also was a much larger problem with creosote and soot buildup in the coal locomotives compared to oil ones. It tends to build up and reduce thermal transfer from the fire to the boiler. The engine crews often throw sand into the pipes to scour out some of this material which also eats up the pipes, but it is also necessary to actually clean them when the equipment is in maintenance. So there must be a mad rush to do it in ports, because otherwise out a sea, it would be necessary to always have a percentage of boilers out of service being cycled through maintenance at any time and not nearly have the full use of all of them.

[@kundeleczek1]

That was informative.

[@rrice1705]

I'd like to know how this affected the ships' galleys, if at all. Stoves and ovens on those older ships were often coal-powered. Did they keep using coal after the conversion, or was the galley equipment converted as well? Great vid!

[@gregorymalchuk272]

That's a good question. I would have suspected that they would have been producing coal gas for gas ranges rather than directly burning it in the galley, at least late in the era of coal. I would really like to know what happened after the oil conversion.

[@kimmer6]

@@gregorymalchuk272 My dad served on a USN troop transport in WWII that was built in Germany as an ocean liner in 1908 before the Titanic. It was old when it served in WWII but had been converted to burn fuel oil instead of coal. He was one of the engine room crew. He often told of how the oil stoves (not coal gas) in the galley would get burners plugged up and the flame would be sooty and uneven. He was always mechanically handy and the cooks would ask him to fix the stoves. In return, they usually baked him a fresh pie to take down to the engine room crew. He always told of a little Japanese prisoner of war that they transported from Honolulu to San Francisco. He spent the whole trip in the brig. My dad said he was smiley and animated and various crew felt sorry for him and brought him small treats. One time my dad brought him a slice of cherry pie fresh from the galley and he was absolutely thankful and delighted. His name was Kazoo. He drew a haiku poem on a piece of silk in India ink and presented it to Pop. He still had it when he died in 2002. It said something about the joy of being among blooming cherry blossoms in the Springtime. What I found out by accident was that the Japanese guy was Prisoner of War #1. He had been piloting a miniature sub assigned to sink a battleship in Pearl Harbor on December 7, 1941. The sub had navigation troubles and ran up on a beach. Kazoo was taken prisoner and I think the other crewman was shot. The Japanese Navy was so ashamed of him that they erased his name and made him non existent. He lived long after the war was over. The ship was The Konig Wilhelm II which was seized by the USA as a WWI war prize, renamed the Madawaska, then renamed again as the USS Grant in 1922. It served in the Pacific and brought troops to the Kiska and Attu invasions. The oil fired stoves question brought up the memories. The ship was scrapped in New Orleans at the end of 1945.

[@phyconautwaterworld198]

Two things that I recall from the coal-fired furnace of our house in the 1950s were that coal dust is insidious stuff that gets into everything and that you end up with clinkers to dispose of. How was that handled with coal fired ships? Did they just throw the clinkers overboard or were they off loaded during coaling?

[@Lawrence330]

Probably overboard. Outside of 3-25 miles from land, pretty much anything can be discharged except oil or plastic. And that's modern day, I'm sure the law 100 years ago was a little more "lenient."

Not all of Society benefited from the switch to oil (5.03). It started a depression in the South Wales coal mining community that it hasn't recovered from yet. When the Royal and Merchant Navies switched to coal many thousands were out of work

[@billogrady882]

Though I haven’t read each and every comment (yet), I am think a point was missed; the conversion of naval ships to oil (Great Britain being the first, under First Sea Lord Churchill?). The US was an oil exporter until after WW2, so US strategic needs were secure throughout WW1 & 2. Great Britain had coal, but no oil. That was only available from colonies in the Middle East (Iraq/Iran, et al), and the Suez Canal. That influenced events in WW1 (Ottoman Empire & Lawrence of Arabia), and WW2 (Africa & Mediterranean Campaigns). Also influenced Japan and their SE Asia Campaign, with Germany going into the Caucaus.’ All because oil was a strategic need for the navies.

[@NonsensicalMRZKAM]

Ngl quite good Christmas gift for us

[@skovner]

Your videos are generally excellent. But the thermal output depends on the input. You give the output for coal and oil, but not how much coal and oil it took per the output. Without that, the comparison is meaningless. But I ask this nicely, not to criticize you much, as your videos are so much better than most.

[@nighttrain1236]

[@walterburger5281]

Just like the railroads conversion from coal to diesel.

[@user-de2wn3he5s]

Except, this is taking advantage of the multi-fuel capabilities of steam engines. And this is just converting to burning a cleaner fuel.

[@Bartonovich52]

Pretty much anything can be multifuel. Run wood or coal through a gasifier and internal combustion engines will run on that too-in fact, just about everyone from Americans on the home front dealing with gas rations to Germans dealing with the complete destruction of their POL reserves did just that. Lots of railways had oil fired steam trains. While UP Big Boys were (mostly) coal-fired up until retirement… CPs Royal Hudsons and Selkirks were oil fired starting in the 1920s. The big drive to dieselization was to reduce maintenance and labour costs. WWII intervened where oil and diesels were required for the war effort (as well as things like steam turbines and gears which is why Liberty Ships used anachronistic Triple Expansion reciprocating steam engines) which slowed the process, but the post-war economic boom accelerated it. Diesels didn’t need hours to build up steam or to have a fire continuously going. They didn’t require boiler tube cleaning or replacement. They didn’t need an army of oilers and wipers for exposed rods and linkages. They didn’t produce corrosive steam and smoke which greatly limited their lives. And they didn’t produce hammerblow wear on the rails as a result of uneven power application and unbalanced reciprocating assemblies. Steam was replaced in ships for largely the same reasons. Diesels were quicker to respond and more economical to run and maintain. Where speed or size was a drawback, gas turbines were used instead mainly in warships starting in the 1960s.

[@Lawrence330]

@@Bartonovich52 Regarding gas turbines (GTEs), absolutely! GTEs start up much quicker than boilers of any kind, and are typically pretty efficient, too. Imagine coming in to work days ahead of time to fire boilers and build up a good head of steam before your ship gets underway, then compare that to, essentially, going out to your driveway and starting your car.

[@alec4672]

Not only did the coal have to be distributed evenly and the right amount of coal in a boiler, additionally the air intake had to be tuned right, the dampers had to be open just the right amount but not too much, effects like gasification could occur if there were organic material still in the coal, ect. Probably about 50 factors in getting a coal boiler burning good. Now multiplied by up to 20 boilers, that's allot of ducks to keep in a row.
