The effect of boiler side parameters of any coal fired power plant is tied to several factors such as excess air, unburned carbon, coal moisture, etc. The two such parameters which have major impact on plant performance is the flue gas temperature and boiler efficiency and these two parameters are closely related to air heater performance.

Until recently, the design of radial, axial and circumferential seals installed on rotary, regenerative air preheaters had not evolved meaningfully from original metal strip arrangements that date back to the inception of the Ljungström preheaters nearly a century ago. Conventional metallic strip air preheater seals can start to degrade immediately following installation, allowing excessive air-to-gas leakage which translates to increased fuel consumption and fan power draw over the life of the seals.
