Boiler Spare Parts APH Boiler Air Preheater Regenerative Air Preheater
Regenerative Air Preheater Descriptions:
An air preheater (APH) is any device designed to heat air before another process (for example, combustion in a boiler) with the primary objective of increasing the thermal efficiency of the process. They may be used alone or to replace a recuperative heat system or to replace a steam coil.
There are two types of air preheaters for use in steam generators in thermal power stations: One is a tubular type built into the boiler flue gas ducting, and the other is a regenerative air preheater.These may be arranged so the gas flows horizontally or vertically across the axis of rotation.
Another type of air preheater is the regenerator used in iron or glass manufacture.

Working principle
1. The solar collector absorbs solar energy and transit the heat to the tank through heating-liquid.
2. When the temperature of collector and tank bottom temperature difference reach to 8 degree, the circulating pump start running to take the solar heat to tank.
3. The tank heat exchanger coil will transfer the heat with outside cold water to reach customer's hot water using.
4. If there is no sunshine or not enough sunshine, it can start E-heater, heat pump unit or other auxiliary heating sources ensure enough hot water for users.
