The boiler air preheater is a key component designed to raise the temperature of the air entering the boiler. This increases the boiler’s thermal efficiency. During operation, the air preheater recovers heat from the flue gas. It uses this heat to warm cold air before sending it into the combustion chamber. This leads to more

Definition of the Air Preheater In thermal power generation, the boiler is undeniably a critical part of the production process. It serves as the heart of the entire power generation system, consistently supplying the necessary power and energy. The air preheater, a key component of the boiler, plays a vital role in optimizing the system.

Impact of Fuel Quality Low-quality fuel typically contains high levels of ash, sulfur, and other impurities. These impurities produce significant amounts of smoke and harmful gases during combustion, leading to severe clogging and wear in the air preheater. For instance, when the sulfur content in the fuel is high, sulfur dioxide generated during combustion combines
