An economizer for boiler or flue gas is a heat recovery unit system designed to recover heat by installing it on the stack of the boiler. Economizers can be installed on the existing boiler system or during new boiler installation They recover thermal energy that can go wasted. They use fluids to utilise this waste heat effectively at a lower temperature than any other gas.
Using an economizer, the overall efficiency of the steam boiler can be increased up to 10% which means you are reducing the overall billing costs per year. Economizers can be used for various purposes ranging from steam and hot water applications, lower stack temperatures, preheating of boiler feedback and capturing waste heat from the stack.
Here are a few considerations you need to make when purchasing a boiler economizer.
Specification
Before selecting an economizer you need to understand the need for industrial boilers such as closed vessel boilers that use electricity or generate steam and humidification. Depending upon the specifications you need to choose the one that perfectly suits your industry.
Features
There are varieties of economizers such as condensing, open feedwater and closed feed water economizers. Open feedwater is a direct contact heat-exchanger that requires a feedwater pump at both the inlet and outlet. Closed feedwater is tube heat exchangers that do not require pumps at the end of the outlets.
Conclusion
If you want to increase the efficiency of the steam boilers in your industry then look for a reputed heat-generating solution company that offers a range of boiler economizers made of prime quality materials with features including finned tubes, stainless steel, and hinged and stainless steel access doors.
