The working principle of boiler economizer:
Boiler economizer is to use the waste heat of boiler exhaust gas to feed water to heat the heat exchanger. The economizer absorbs the waste heat of exhaust gas, reduces the exhaust gas temperature, and improves the working efficiency of the boiler. Add a heat recovery process to the cycle, reduce the thermal stress on the drum wall caused by temperature difference, thus improving the working conditions of the drum, extending the service life of the drum, increasing the average temperature of heat absorption, and thus increasing the cycle efficiency.
The role of the boiler economizer:
Boiler economizer is to increase the water inlet temperature of the boiler. The economizer is located in the tail flue of the boiler. When the smoke after boiler combustion passes through the tail flue, it passes through the economizer. There is a coil in the economizer. The coil is the water inlet of the boiler. The water in the coil absorbs the heat in the flue gas, and the cold water becomes hot water.
The installation position of the boiler economizer:
Boiler economizer is that the heat exchange equipment is generally installed in the tail flue, which uses the waste heat of the tail flue gas to heat the water supply, improve the water supply temperature, and reduce the heat absorption of the water supply on the heating surface. At the same time, the feed water temperature increases, reducing the temperature difference entering the drum wall, reducing the thermal stress and extending the service life of the drum.
The boiler economizer is composed of tube coils, bare tubes or finned tubes
Boiler economizer to increase inlet water temperature of industrial boiler
The economizer of the boiler is located in the tail flue of the boiler. When the flue gas after boiler combustion passes through the tail flue, it passes through the economizer. There is a coil in the economizer. The coil is the water inlet of the industrial boiler. The water in the coil absorbs the heat in the flue gas, and the cold water becomes hot water before it enters the boiler, which increases the temperature of the boiler water inlet.
Boiler economizer improves boiler life：
The heating of low temperature water into high temperature water or steam by industrial boilers is very costly for heat exchange elements. After the boiler economizer heats the water entering the boiler, the process of heating the hot water with cold water by the industrial boiler body is saved, and the hot water can be directly heated into steam or higher hot water. The saving of this process can greatly improve the life of the boiler body, and a boiler equipped with an economizer can often be used for a longer time.
