Quick Details Specifications
The boiler economizer is an indispensable mechanical device for coal fired boilers, and is located at the boiler flue, where heat is captured from the flue gas in order to pre-heat cold water inlet or heat the boiler feed water. Our economizers are generally made of 20 low and medium pressure boiler pipes, 20G seamless steel tubes or ASME grade steel tubes. It reduces the flue gas temperature and maximizes the heat recovery to help customers reduce fuel costs. When entering the steam drum, the temperature of the feed water is increased after it has been heated using the economizer. The thermal stress caused by the temperature difference between the steam drum wall and the feed water is reduced, which reduces the shrink and swell in the steam drum. Our economizer is an excellent, less expensive replacement for high temperature boiler water wall tubing, thus reducing manufacturing costs for coal fired boilers.
1.Fuel saving: After the high temperature fuel gas released by fuel combustion transfers to the boiler water wall tubing, superheater, and reheater, the temperature is extremely high, the economizer makes it ideal for preventing heat loss. The economizer located at the flue of the boiler reduces the flue gas temperature, and maximizes the heat recovery to lower customer fuel costs.
2.Improvement of boiler steam drum working conditions: When entering the steam drum, the temperature of the feed water is increased after it has been heated using the economizer. The thermal stress caused by the temperature difference between the steam drum wall and the feed water is reduced, thus reducing the shrink and swell of the steam drum, and extends the service life.
3.Cost reduction of coal fired boilers: Water is being heated in the boiler economizer made using low temperature material. This makes the economizer a less costly replacement for high temperature boiler water wall tubing, and reduces overall boiler manufacturing costs.

Internal heat exchangers
1.Subcooling may also be produced by superheating the gas leaving the evaporator and heading to the gas compressor.
2.These systems withdraw heat from the liquid line but heat up the gas compressors suction.
3.This is a very common solution to insure that gas reaches the compressor and liquid reaches the valve.
4.It also allows maximum heat exchanger use as minimizes the portion of the heat exchangers used to change the temperature of the fluid,and maximizeds the volume in which the refrigerant changes its phase.
