A COAL FIRED STEAM TEST OF THE CASTLE STEAM V6 BOILER - PART #1

[@stamrly418]

Defiantly a candidate for that steam boiler feed pump you have / had. So much steam it needs to be used. The speed the gauge reacts is wow. Great plant and reacts to the blower dramatically. It could feed a whole bunch of engines..... that would be a video to wait for.. but that is just dreaming.. good work again..thanks for doing it.

[@daveshaw9344]

This is so soothing to listen to, helps me relax before I go to sleep :)

[@phoenixrising4573]

So jealous of such a beautiful plant! Wish you still had the double 5a to steam on it.

[@keithappleton]

Yes that was a nice engine - but alas it belongs to a customer - I never owned it . . . .

[@steveparker8723]

Beautiful boiler and engine.

[@keithappleton]

Yes, it is beautifully made and Steams extremely well.

[@marekmarko2274]

I love the oil pump on the engine! I made similar. I used pre-heat steam and the condensation oil feed doesnt work on it, but this oil pump always does. I also add bypass valve and can regulate how much oil go to engine the rest go back in to oil container.

[@randynovick7972]

This was great! I have questions, but I'll save them for the end of the series. Thanks for letting us see all the details.

[@Mister_Brown]

that is one hell of a boiler. i'd love to see it running a double 5a generating power, looks like it could keep up with some serious output.

[@fungas4804]

Great work Keith, it looks beautiful and works similarly. You made me laugh as the water level got low, pumping more and more water in, getting faster and faster - yes, a candidate for a live steam water injector...

Thank you, I am not a writer, but I did write a few article for "Engineering In Miniature" magazine a while back. I am pleased that you get something out of watching the videos }:-))).

[@davidfritschen8414]

Thanks for your videos. And thanks to you and boiler review, I too Ordered a boiler from Castle Steam, "The Bug" not the V6. But the same quality of design and detail as the V6

[@alobowithadhd6191]

Something mesmerizing about watching someone stoke a steam boiler and watching that pressure gauge rise. Oh, the reason this boiler works so well is the way it mixes the air to fuel ratio. I forget exactly what they are called, but there is another set of walls inside the firebox that allows the fuel to mix with the air more and more as it reaches the top, all before the gases escape. This provides an extremely efficient combustion process that adapts to the fuel used inside. The bottom vents keep the fire going, and the excess gasses go up the wall mixing with air until it burns the last of the combustible vapor.

[@1stPCFerret]

Beautiful job, a always. Looks like it could use an injector if only to keep you from having to hand-pump water so often!

[@douglaslambert6109]

Or a econoic water pump to the engine.

[@Uberaroundtheworld530]

How many horsepower does this produce like 1-2? I want to make a steam generator for my property

[@keithappleton]

From the stuartmodels.com Website: A Stuart 5A will produce 1.5 HP at 80 PSI.

You could run a decent DC alternator on that. Nice setup there.

[@viking1ur]

One thing is verey often not included in all this nice videos on youtube. And that is a usefull purpose of the power made by these small machine like pumping hot water in tube around inside your house to heat it or som other aplications. The motor wil probably have an oter sound also when working harder. Maybe every home should have one in these times when electrisety prises is sky high.....btw - beautiful made video - thank u...

[@DeNilsPipe]

You have quite interesting haribo over there on the island... 😄

[@kmajors]

Keith thanks for the videos. It is a very nice boiler and seems to generate quite a lot of steam. How many engines could you run off this boiler at the same time? It might be fun to hook up several and see how well they work. Thanks for the effort and interesting videos.

[@haraldpettersen3649]

Fantastic , just fantastic .

[@rhavrane]

Bonjour Keith, This boiler is very efficient and your water pump seems quite little for it. With this high pressure, would it be possible to install an injector as it is a static steam plant ? Amicalement, Raphaël

[@JamesPetts]

That is a very impressive boiler.

[@JonatanGronoset]

Lovely little plant. I'm no builder of steam engines but if I made a plant like this I think an eccentric-driven pump would be good for dealing with the water. I imagine your arm would be sore after this session. ;)

[@P61guy61]

A most excellent video. Thank you for posting!

[@ViaAvione]

Amazing! Does it have enough torque to spin a Alternator or Generator?

[@keithappleton]

Yes it is 1.5 HP

[@abecoulter18]

Where can I buy one of these

[@keithappleton]

Ebay ? I sell them sometimes www.mainsteam.co.uk

[@Herby-1620]

It seems to work well. Question: Why does the sight glass change while things are "static", no engine running, no injecting. It seems to bounce up and down for no reason.

[@keithappleton]

because the water is boiling inside the boiler . . . if your domestic kettle has a sight glass watch what happens as it boils . . . .

[@marknagy5892]

Very nice steam engine !

[@Peltierelement]

Very Good Video as usual! Can you show how the firetubs/ fire pipe looks like under the chimney?

[@bullettube9863]

Look folks, he's having a steam picnic!

[@modelsteamers671]

That's great Keith, many thanks for taking the time to upload it, I've wanted to see how these boilers perform on coal for some time as I'm thinking of treating myself to one. It's impressive how quickly the pressure rises and it seems to power the 5a effortlessly. Do you think it would be a bit too efficient and be constantly blowing off if it was being used to power a much smaller engine? The pressure doesn't seem to drop much with the firehole door open so I'm wondering how easy it will be to control if you only require a modest steam output ? Many thanks, I look forward to the next video :-)

[@keithappleton]

it is everything that you need it to be - great on Gas - really great on Coal ...... I highly recommend these boilers in every way possible (I am not financially connected with Castle Steam in any way and also I am not on any commission).....

[@modelsteamers671]

Thanks, as you know I've had trouble will my previous boiler and taking the builder to court, I'm due to treat myself to a new toy

[@castlesteam8642]

Hi Model Steamers, I have enjoyed watching Keith put our boiler through it's paces. You always wonder if everything will go well (heart in mouth moment). I am pleased with what I have seen but questions have been raised and must be answered. We really appreciate the interest and comment on our boiler. The V6 boiler has a large firebox acting as the most efficient heat exchange area of the boiler. When using coal it also becomes a great absorber of radiant energy. The radiation will act downwards as much as any other direction so care must be taken to build an appropriate fire for the need in hand or continuously blowing safety valves and burnt baseboards will happen. The V6 will run beautifully with quite a small coal fire and with no drama. For small engines gas is recommended as even a 12kBThU camping burner was able to drive a double 5A (but very slowly) with no radiation issues. With gas the ashbox assembly remains cool and the boiler is always completely under the control of the gas supply valve. But if coal is your thing please enjoy but build with care. I will be upgrading the stainless ashbox assembly for coal fuel alone to take into account possible issues with large coal fires. The upgrade will include thicker gauge materials, more ventilation control (down to complete damping), and downwards infra-red radiation control (possibly ceramic). Safety has always been at the forefront of this design, hence if all else fails lift the boiler off the fire. That's why it is designed this way. The idea was not to generate your own BBQ charcoal. The V6 boiler was designed specifically to drive large Stuart engines, on coal fuel, and drive them well. I hope that this will be achieved with a few tweaks. Thank you Keith for your patience and not moaning about the damage to your well made baseboard. You can ask me questions directly at [e-mail]. I'm happy to answer them.

[@azlandpilotcar4450]

Is some of the efficiency of the boiler connected somehow with the flames that appear, in the video, to be underneath the firebox in the ash pan?

[@keithappleton]

No, the heating is all taking place above the ashpan {:-)))

[@haydenbrown8421]

Keith, Would this boiler and engine arrangement power a small one person steamboat in your opinion with moderate demand on speed, say 2-4 mph? Want to build a steamboat for personal use but don't want a Windermere size 18 footer or the like. Just a boat powered by steam for a small lake. Any thoughts what might work? This boiler certainly has a great responce to a bit of blower.

[@steamboatmodel]

Hayden Google Steam Canoes

[@keithappleton]

it would easily power a small full size boat probably faster than 4 MPH . . . .

[@CreaseysWorkshop]

Hi Keith, what a lovely boiler and engine. Do you know if the little dome on the cylinder cap is machined or is it as cast? It looks very smooth.

[@keithappleton]

It is cast and then machined.

[@rogercrier]

At 2.19, who else thought "chocolate!".......or is it just me? I know an injector is coming, so the hand pump will hopefully be an auxiliary method for the most part, but you do seem to be doing a lot of pumping! Could the pump be a bit bigger, or does it need to have a small sized ram to get the water in against 100 PSI (Pleasurable Steam Increments)

[@patmancrowley8509]

Time to dove-tail both boards so that you can give them a temporary lock-together so they don't dance away from each other. That sure is a lot of hand-pumping.

[@WayneJohnsonZastil]

Can you send the steam coming out back into the boiler?

[@keithappleton]

No, once it's done it's work it is spent. Some steam engines use the steam twice though, with a high pressure and then a low pressure cylinder, they are called "Compound Steam Engines"

[@horatiohornblower868]

I am an absolute layman but I've often wondered why the steam leaving the cylinder is not recuperated by leading it through a condensor. In that way the water could be endlessly recycled.

[@keithappleton]

because exhaust steam has steam oil in it and it's difficult to separate in small scales.....
