Stack economizer
Recover heat from flue gases that would otherwise be wasted and use it to preheat boiler feedwater.
Heat recovery & exhaust
Recover heat, vent it right.
Economizers, blowdown and flash tank recovery, HRSGs and waste heat boilers, plus stacks, special gas vents and SCR from Cleaver-Brooks, Selkirk and HeatFab.
Heat recovery
Put wasted heat back to work
Condensing economizer
A 2-stage condensing economizer that can raise fuel-to-steam efficiency up to 95%.
Flash tank heat recovery
Recover heat and steam to use as-is or to heat new feedwater, saving fuel and money.
Blowdown heat recovery
Automatically controls surface blowdown to hold dissolved solids where you want them and recovers 90% of the heat normally lost.
Heat recovery steam generators (HRSG)
Custom HRSGs for a wide range of applications, including heat recovery from gas turbines.
Waste heat boilers
Reduce fuel and energy expenses as well as greenhouse gas emissions.
Exhaust solutions
Stacks, vents and emissions control
Cleaver-Brooks exhaust systems
Installation-ready and freestanding stacks with a male/female slip-type joint that removes the need for adapters. All vent systems are UL and cUL listed and laser welded.
- Includes: chimney liners, boiler exhaust, freestanding stacks, special gas vents for condensing boilers
Grease ducts
Exhaust system components for removing smoke and grease-laden vapors in commercial, industrial and institutional applications.
Selective Catalytic Reduction (SCR)
A post-flue gas treatment that reduces NOx from a wide variety of boiler systems, with reductions up to 95%. Works with firetube, industrial watertube, HRSG and retrofit boilers.
