Energy Recovery

Cleaver-Brooks Heat Recovery Solutions

Reduce costs and environmental impact by recovering waste heat or steam and using it for other system applications. 

  • Stack economizer – reduce fuel usage and cost by recovering heat from flue gases that would otherwise be wasted. Save up to 5% on your fuel bill with the use of an economizer.  For systems with high make-up we recommend installing a two stage economizer. Two stage economizers include a second stage used to preheat deaerator makeup water, which can increase your boiler efficiency up to 95%.
  • Condensing economizer – save on fuel costs and increase fuel-to-steam efficiency up to 90%
Boiler Economizers

Cannon Boiler Works Economizers

Three major parameters are considered in evaluating all boiler economizers; 1) fuel type, 2) acceptable backpressure on the exhaust, 3) inlet water temperature.   These will determine which of our following heat recovery product is best for you.

  • Feedwater Heater – normally used on small boilers burning natural gas, and non-condensing flue gas environments. Inlet temperatures 150F to 250F
  • Gas Condensing Water Heater – normally used on small and large systems burning natural gas, and condensing flue gas environments. Inlet temperatures 40F to 150F
  • Heavy Duty Economizer – normally used on large systems burning dirty fuels, and non-condensing flue gas environments. Inlet temperatures 200F minimum
  • On-Demand Economizer – fits where other systems will not. Normally systems burn natural gas, and condensing flue gas environments. Inlet temperatures 40F to 150F
  • Dual Stage Economizer – used for heating two separate streams with the same economizer. Can be used on small and large systems burning natural gas, and condensing or non-condensing flue gas environments. Inlet temperatures 40F to 250F

Exhaust Solutions

We offer pressure sealed prefabricated boiler stacks designed to meet the code for forced draft boilers. These stack systems are a long lasting option to installing welded steel. Stacks are modular and factory pre-fabricated, employing a flanged joint design, allowing quick installation and pressure sealed performance. Stacks are furnished with a double wall design and made with stainless steel inner pipe. Offered with insulating air space or ceramic fiber insulation between the double wall material, these stack systems provide UL Listed clearances to combustibles. Each is furnished with layout drawings detailing all required fittings, including support and expansion allowance, providing for a complete, engineered venting system. All vent systems are UL, cUL listed, laser welding and ideal or commercial, industrial and institutional applications.
