: Superior Boiler made the biggest firetube so far and it was a 2200hp. Then again I agree that serial number one is not a good amount of history. I believe johnston is in the process of making a 2500 HP but im not sure. Also Don Lee (aka York Shipley) has made some 1800 HP. I personaly would not go with a firetube over 800HP and I also agree that the potential for more casualties from a firetube explosion than a watertube is high. This is a good conversasion
: and I don't mean to come down hard on you but in a perfect world one does not expect his boiler to explode and I beleive any pressure vessel that was to B.L.E.V.E. is going to be pretty severe regaurdless of the size of the boiler. Someone is going to get hurt by way of blown doors or or total failure. Watertube will contain most of the explosion from a combustion standpiont just by the way they are designed and constructed than a firetube.
Guys,
Johnston has been building 2500HP FT boilers for quite some time both single and multi burners. There is noting unsafe or bad about these boilers. Typically the major issue is shipping since these units are so large. There are many 1000HP+ units running today that have been in service for more than 5 years without a single problem. Most of which are 200 - 300 MWAP If any one has ideas that these boilers are dangerous contact the NBIC and search for any damage reports. As for other manufacturers building 1000+HP FT Boilers there are no others than Johnston. The others only try to build a large FT Boiler.
