Industrial Certificated Economizer for Boiler on Sale

Boiler Economizer

Economizers are tube heat exchangers located in the top section of a boiler. They raise the feedwater temperature to slightly below saturation temperature. Economizers are so named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency. Economizers preheat the cold water used to fill water wall panels.

Application: 
Economizers consist of parallel-mounted steel tubes, butt welded and bent, and subject to the highest pressures and lowest temperatures. They need good mechanical strength at metal temperatures up to 380 °C (and/or steam temperatures up to 330 °C). Accordingly, they are usually made of carbon steel.

When you purchase a thermal fluid heater, the cost of fuel to operate the heater is a major concern. The amount of fuel needed is related to the thermal efficiency of the heater. Increasing its thermal efficiency reduces the amount of fuel needed as well as operating costs. 

An effective way to increase a heater’s thermal efficiency and reduce fuel costs is to install a special heat exchanger in the heater’s exhaust stack. The heat exchanger recovers heat from the exhaust stack that would otherwise be lost into the atmosphere.

This special type of heat exchanger is known generically as an economizer or convection section. It consists of an enclosure that contains coils of pipe, and the enclosure fits between the heater and the bottom of the exhaust stack.
