Manufacturing and acceptance criteria

*Note:HD BOILER can bespoke special type of economizer according to customer's requirement.

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.

Competitive Advantage

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.

Parameters of Boiler Economizer

Working Process of Boiler Economizer

There are three stages from the feed water in the boiler heated into superheated steam:feed water preheating, evaporation, and superheating. The three stages are finished on three different heating surfaces. The boiler steam and water circuit are composed of the three different heating surfaces as well as their connecting pipes. Boiler economizers are one of them, and it is right the equipment to preheat the feed water. Thus, it is the heating surface with the lowest temperature for boiler working fluid in the boiler steam and water circuit. The working fluid passing through this equipment is monophasic water(non-boiling economizer).
