80 Ton Gas Boiler Part Air Preheater Heat Exchanger Enamel Tube In Thermal Power Plant
Product Description
Airpreheater is a general term and represents any heater designed
to heat air. It may be for residential use namely for room heating,
house heating, etc. by means of gas, electricity or oil etc. In the
present context reference is to the airpreheaters used in steam
generators (boilers) for generation of electricity in Power
Generation Utilities.
The purpose of the air preheater is to recover the heat from the flue gas(exhaust gases) from the boiler to improve boiler efficiency. Incidentally the gases are sent to the chimney or stack at lowered temperature so that the design of the ducting and the stack becomes simplified. Also it controls the temperature of gases coming out of the stack.
Different types
For the use in Steam Generators (boilers)in Thermal power stations of Utility power stations, there are two types of design of the Airpreheaters. One is a tubular type built into the boiler outlet Flue_gas ducting and another one is of the regenerative type known as Ljungstrom (named after the name of inventor) Regenerative Air Pre Heater(RAPH),a rotating type. This may be horizontal (now very common in power generation utilities) or vertical.

Product advantages
1. High corrosion resistance property;
2. Small covering area;
3. Pipe and tube plate in every link between separated, the heated bilges cold heat distortion is not bound to avoid stress destruction;
4. Single pipe, tube single or parts of equipment failure does not affect the heat normal operation, two fluid were heat tube, can go outside fin
