Analysis of Performance of Ljungstrom Air Preheater Elements

The warm gas and cool air ducts are arranged to allow both the flue gas and the inlet air to flow simultaneously through the air preheater. The hot flue gas heats the rotor material and as the rotor rotates, the hot rotor section moves into the flow of the cold air and preheats it. The performance of Ljungstrom Air Preheater is depended on

Regenerative Rotary Air Preheater / Gas Air Heat Exchanger

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.
