Cain Economizer Systems


Accessories for your Boilers Feedwater Systems

Cain Industries offers an extensive selection of boiler economizers specifically designed to recover the lost heat exiting from exhaust stack and preheat water. Our broad line of economizers covers the spectrum of boiler sizes, ranging from very small hot water boilers with burner inputs of 200,000 Btu/hr to large boilers delivering steam at 250,000 Ib/hr. In addition, Cain produces boiler feedwater systems, condensate tank and pump systems, exclusive sootblower assemblies, and unique modulating internal exhaust gas bypass systems

System Function

Boiler exhaust recovery internal process

Exhaust heat from combustion typically leaving the stack and into the atmosphere is instead transferred from the exhaust steam by means of a Cain Economizer. This lost Btu is now captured and saved to various heat sinks such as boiler feedwater, cold makeup water, process water, swimming pool water, glycol, and thermal fluids. Combustion source fuel types including natural gas, propane, digester gas, diesel fuel, and No. 2-6 fuel oil are all heat sources which can be retrofitted with Cain heat exchangers.
