Boiler Air Preheater In Thermal Power Plant High Pressure
Energy saving New Industrial Boiler Tube Air Preheater with Enameled Tube
Product Description
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
