Biomass Boiler Air Preheater
Descriptions:
Air preheater(APH)is the shell and tube type heat exchangers used
for preheating the air which is fed to the boiler or furnaces/
kilns for combustion of fuels. Air preheater’s primary objective is
to extract the waste heat from the flue gases leaving the boiler.
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.
Advantage of air preheater
- Increases thermal efficiency of the system
- Payback period is very short and increase combustion rate
- Improve and strengthen the combustion
- Reduces the loss of furnace and the exhaust gas temperature,
improve the boiler thermal efficiency.
- Air preheater is suitable for all standard fuels
- They are easy for retrofit into existing systems
- These air preheaters are suitable for all waste heat boiler / flue
gas boiler / boiler types.
- They strengthen the heat transfer

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.
