What causes high exhaust temperature of biomass-fired boilers?

27 Apr 2023

High exhaust temperature in a biomass-fired boiler can be caused by several factors, including:

1. Insufficient air supply: If there is not enough air supplied to the combustion chamber, the fuel may not burn completely, resulting in high exhaust temperatures.

2. Excessive fuel supply: Excessive fuel supply can overload the boiler, causing incomplete combustion and high exhaust temperatures.

3. Improper combustion: Improper combustion can lead to incomplete fuel burning and high exhaust temperatures. Factors that can contribute to improper combustion include poor fuel quality, incorrect fuel-to-air ratio, and inadequate mixing of fuel and air.

4. Scaling and fouling: Scaling and fouling of heat transfer surfaces can reduce the heat transfer efficiency of the boiler, leading to high exhaust temperatures.

5. Insufficient water flow: Insufficient water flow through the boiler can cause localized overheating, leading to high exhaust temperatures.

6. Damaged or worn-out components: Damaged or worn-out components, such as burners, heat exchangers, and fans, can lead to inefficient combustion and high exhaust temperatures.

7. Inadequate insulation: Inadequate insulation can cause heat loss from the boiler, leading to high exhaust temperatures.

To prevent high exhaust temperatures in a biomass-fired boiler, it is important to ensure proper air supply and fuel-to-air ratio, maintain and clean heat transfer surfaces, and replace damaged or worn-out components as necessary. Routine maintenance and inspections can help identify and address potential issues before they lead to high exhaust temperatures. Additionally, installing appropriate insulation can also help reduce heat loss and maintain optimal exhaust temperatures.
