Description

H Type Tube Exhaust Gas Economizer High Efficient Heat Exchange With Headers


Economizer/ Heat exchanger Introduce


Econimizer is a device that installed below tail fuel of boiler for recover waste heat from exhaust fumes.
The boiler feed water is heated into the heating surface of saturated water under the pressure of steam drum. As it absorbs the heat of high-temperature flue gas, it reduces the exhaust temperature of flue gas, saves energy and improves efficiency, so it is called Economizer.

The H-Type Economizer is not restricted by pressure and can be used as a boiling type, which is generally controlled by carbon steel with an outer diameter of 32 ~ 51 mm. Sometimes the fin and fin are added to the tube to improve heat transfer. The steel-pipe coal saver consists of parallel curved pipe (called serpentine pipe) arranged horizontally.
The economizer is mainly used for industry, and it is gradually applied to agriculture and some related industries.


Technical specifications



Material Structure
Consists of a serious of H-finned tubes, the headers of inlet and outlet, bend, frame and other auxiliaries.
Structure Arrangement
In line / staggered arrangement.


H Type Tube Exhaust Gas Economizer High Efficient Heat Exchange With Headers

Functions


1. Absorb the heat of low-temperature flue gas, reduce the smoke exhaust temperature, reduce smoke loss and save fuel.

2. Since the feed water is heated in the economizer before entering the drum, the heat absorption of the feed water on the heating surface is reduced, and the economizer can be used to replace part of the high-cost evaporative heating surface.

3. When the feed water temperature is raised, the wall temperature difference will be reduced and the thermal stress will be correspondingly reduced to extend the service life of the steam drum.

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.
