converting 4 section to a 3 section boiler

Tom_34 Member Posts: 2
Is it possible to remove a section from a 4 section boiler and make it a 3 section ???? I'm quessing you'd also have to change the nozzle and the air tube ??? Has anyone done this before. The reason is the boiler is to big and is short cycling.The boiler is about 50% to big....Thanks

    you can just de-rate the boiler reduce the nozzle size //drop the nozzle size --you will need instruments you need to adjust it // keep the flue gas temp at 350 minimum if it gets below that you will have chimney problems--any condensation in the chimney will turn the ash/soot into sulfuric acid and will destroy the liner///there are more detailed instructions on this procedure w/actual numbers and manufactures recommendations im no expert at this but it is done for high altitude applications all the time ---- they "re-rate" the boiler

    simply cover it with chicken wire and asbestos.

    For all

    the effort to remove a section? I think you would be better off simply decreasing the firing rate and consider a different control strategy. Such as a two stage thermostat or something. Spread your high and low limit further apart, increase the differntial.

    What, exactlly do you call short cycling ? Most boilers are oversized by 2X
