What is the flue gas economizer?

Economizer, also called flue gas waste heat recovery equipment, is an energy-saving equipment that can improve economic performance. It is commonly used in the combustion boiler industry.

1、  What is the flue gas economizer?

As an environmental protection equipment, the essence of the economizer is a heat exchanger, which transfers heat in the equipment through two kinds of media with temperature difference and can be used for secondary use. Since most of the gas produced in the incineration boiler industry is gas, the heat exchangers used are generally gas heat exchangers and gas water heat exchangers, which are usually installed at the tail of the gas boiler flue gas to directly recover the waste heat of the exhaust gas.

2、 Advantages of flue gas economizer

There are many advantages of flue gas economizer, which is used to transfer the heat of finished flue gas to low temperature medium, so as to reduce the exhaust gas temperature and hot smoke loss. Some manufacturers recycle high-temperature waste heat flue gas and air heat exchanger, and the recovered air can be used as air preheater to support combustion and reduce the consumption of coal fuel.

3、 Working principle of flue gas economizer

The working principle of the flue gas economizer is relatively simple. There are different channels in the equipment. One channel is high temperature medium, and the other channel is low temperature medium. Heat exchange is achieved through the flow of medium between pipes. This working principle can improve the working efficiency of the whole snake, add a heat regeneration process to the cycle, increase the average temperature of heat absorption, and increase the cycle efficiency.
