Boiler Economizer Systems
Heat Transfer Systems for Boiler Exhaust Recovery
Cain Industries offers an extensive selection of boiler economizers specifically designed to recover BTU exiting the exhaust stack and transfer it back into a desired heat sink. Our broad line of economizers cover 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 lb/hr. Cain also produces boiler feedwater systems, condensate tank and pump systems, exclusive sootblower assemblies and unique modulating internal exhaust gas bypass systems.

System Function
Cain boiler economizers reduce energy cost by capturing valuable heat from boiler combustion exhaust that would typically escape up the stack and into the atmosphere. This recovered BTU is transferred back into heat sinks such as boiler feedwater, cold makeup water, process water, swimming pool water, glycol and thermal fluids. Combustion fuels include natural gas, propane, digester gas, diesel fuel and No. 2-6 fuel oil.
Proposal Considerations
Consider Cain for cylindrical or rectangular stack connections, large or small boilers, a particular pinch point requirement, stack or liquid temperature control, special heat sink requirements, special heat transfer metallurgy requirements, specific maintenance concerns, optional equipment requirements, installation space and weight concerns, and package system requirements.
- Tremendous fuel savings typically pay for equipment and installation within 1 to 2 years of average use
- Pollution reduction equivalent to lowered annual fuel usage
- Longest heat exchanger life expectancy

Exhaust Heat Recovery for Fume Incinerators, Thermal Oxidizers, Catalytic Converters, Industrial Ovens, Kilns and Furnaces
Heat Transfer Systems for Industrial Combustion Processes
Selecting the appropriate heat exchanger or waste heat boiler for fume incineration and other industrial combustion processes involves much consideration. Important areas of concern are controlling/bypassing exhaust waste heat, optimizing heat transfer performance, steam operating pressures, equipment size, weight and installation. Cain Industries' industrial heat exchanger family is specifically designed to address these concerns and more with standard design features not found in conventional heat recovery equipment.
System Function
BTU is transferred from the exhaust of incinerators, thermal oxidizers, catalytic converters, boilers and hot oil heaters to heat sinks such as water, ethylene glycol, therminol fluids, or steam production. Suitable fuel types for combustion sources include natural gas, propane, digester gas, diesel fuel, and light to heavy fuel oils.

Heat Recovery Steam Generators (HRSG) for Engines, Incinerators, Thermal Oxidizers and Catalytic Converters
Selecting the correct "Heat Recovery Steam Generator" (HRSG) for engine cogeneration (CHP) and other industrial waste heat systems involves much consideration. Important areas of focus are controlling/bypassing the exhaust heat, optimizing overall system performance, maintaining required operating pressures, the boiler size, weight and installation. Cain's HRSG families are specifically designed to address these concerns and more with standard design features not found in conventional waste heat boilers. Our equipment will adapt to any retrofit application or new installation. Contact our sales team to receive a comprehensive proposal and quotation engineered to meet your exact requirements (within 48 hours).
