What is the function of coal-fired boiler economizer?

coal-fired boiler economizer, as its name implies, is a boiler device to save energy. The structure of coal-fired boiler economizer is relatively simple, which is mainly composed of all stainless steel 304 frame and stainless steel spiral finned tubes, all of which are arranged in a certain order.

According to the power, size and price of the boiler, the boiler economizer adopts different materials such as stainless steel and ND steel. According to the medium, coal-fired boiler economizer is mainly divided into coal-fired boiler economizer with flue gas-hot water waste heat recovery, coal-fired boiler economizer with flue gas-heat conduction oil waste heat recovery and coal-fired boiler economizer with flue gas-air heat exchange.

The principle of coal-fired boiler economizer is that the flue gas from the tail of the boiler enters the economizer, and the water (or air) in the economizer absorbs the temperature in the flue gas through the finned tube, and then returns to the boiler, which is equivalent to increasing the feed water temperature (furnace temperature) of the boiler, and reducing the energy consumption when the output of the boiler is constant.

Coal-fired boiler economizer is generally equipped at the tail of the boiler. Due to the difference in principle and equipped boiler, there are many names, such as boiler economizer, air preheater, condenser and so on. ZOZEN provides its own coal-fired boiler economizer for customers. The heating area is carefully calculated, the quality is guaranteed, and the thermal efficiency of the boiler system is higher.
