Cannon Boiler Works Heat Recovery
10% to 20% of energy input is lost in the form of heat escaping to the atmosphere. The installation of a boiler economizer helps to solve this problem. An economizer captures heat from the stack and then returns it to a water system.
Three major parameters are considered in evaluating all boiler economizers; 1) fuel type, 2) acceptable back pressure on the exhaust, 3) inlet water temperature. These will determine which of our following heat recovery products 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
