Understanding Boiler Pressure Controls - Boiling Point

Today on The Boiling Point we are joined again by Jude Wolf, one of our Boiler University teachers. Jude is here to talk about Honeywell pressure controls and what these pressure controls actually do for your boiler.
They go by many names: Christmas Tree, Operations Controls, etc. but they all do the same thing: control the boiler's operations. They shut down the boiler when steam pressure limits are made as well as kick the burner on to maintain pressure under a load. They can be confusing and complicated but Jude boils them down to be a bit more understandable.
Key terms:
Firetube boiler
Honeywell pressure controls
boiler pressure controls
pressure control
water level control
boiler shut down
operating control
high steam pressure limit
firing rate controller
short cycling
low fire hold

Remember the value of your boiler system, maintain it properly and save cost in the future.

Get this guy on more videos awesome explanation.

[@wareboilers]

We actually have a whole series in which he hosts and talks about quick boiler tips. kzbin.info/aero/PLtXrfnqEhRXA6rwnsY8CGxsSx_qjOhGr0 check it out and thanks for watching!

[@bykrydr1380]

Thx Jude. You are understandable how you break down the large amount of info/details. Mr. Taylor is great too.

[@wareboilers]

Thanks for watching, glad we can be of help!

[@IRONDICKMECHANICALHVACdavis]

Solid video. Keep learning.

[@alexanderadvincula9276]

great video. thanks

[@alexander-vi5nu]

or can you answer how can it operated safely? efficiently and automatically using l.p and h.p switch

[@PBS-nm1uu]

great demo, first one i have seen, thanks, learned something..

[@wareboilers]

Thanks for watching!

[@lumpiyashanghai4639]

@@wareboilers can I ask something?

[@alexanderadvincula9276]

good morning. I work as a handyman in a residential building in NYC and I would like to learn more about boilers. I see it very interesting. you do meetings in NY?

[@ECAstack]

Isn't the propose of the operating steam pressure switch with no manual reset, to cycle the firetube boiler's burner off and on, on high steam pressure since it's generally wired into the recycle circuit of the burner management system? Wouldn't this keep the boiler nice and hot during low load demands from the plant.

[@jewelwilliams777]

Thank you

[@josephmuriuki5154]

Great explanation

[@wareboilers]

Thanks for watching!

[@themechanic4222]

Hey. But some mechanics called them different names sometimes. Like modulators. (control the 🔥 flame) etc

[@alexander-vi5nu]

hello my teacher ask me how does the boiler operate safely using the low pressure cut in switch ,high pressure cut out switch and safely value

[@wareboilers]

Thanks for the comment! So this video does a good job explaining how the switches work but we just produced a new video that explains the safety valve. kzbin.info/www/bejne/bqPWc2uMaJWCrck Check that out and it should give you a good understanding on how they all work together. Let me know if that helps out!

[@shredct3118]

This is a great video. Are those murphy switches?

[@wareboilers]

Those are all Honeywell Pressuretrol switches. Thanks for the comment!

[@morrismckinnon3012]

So, are any of those the MODULATING CONTROL? Is the low fire the equivalent of a modulating control?

[@NSalivo]

your firing rate control is your modulation control

[@AdrianButler86]

Yes aka modutrol

[@zerozentao]

What kind of tools should I have by default to repair various common problems that can happen to a peerless boiler. Right now. My psi was maxed all of 3 times it fired. Just bought house. I opened all my radiators. I added water to it so it was at the normal level. Then I took water out after noticing psi gage. It could have already been thsy high. It said low water when I took water out to lower psi. So I'm like...fuck. I poked a wire through the copper pipe thst is the little box that regulates the psi. Nothing came out of the psi. And well after I did that. I tried firing it back up. But now it won't fire. Pilot light is lit. I shut power off to it for 30 seconds ect. But still nothing. There is a little circular thing that let's the air out of pipes thag was working also. Anyways I'm avoiding calling a plumber and determined to fix and keep it upkeeped myself. It's warm now but want to get it off bucket list. Holar at me if you could

[@dongertan3320]

Mercury switch is bullet proof and visual.

[@karlschauff7989]

The mercury-free switches are junk.

[@juansulca9037]

The pressue is not 50 PSI, ??????????
