What are the influencing factors of boiler burners?
During the use of boiler burners, it is inevitable that various factors will affect their normal operation,. Compared to us, we are all very clear that in order to understand why equipment cannot function properly, it is necessary to understand the factors that affect its normal operation. So what are the influencing factors of boiler burners? Today, let’s learn about it together.
A sufficiently high temperature to ensure the required heat for ignition while maintaining effective combustion rate. The ignition point of fuel is about 250 degrees Celsius, and its temperature is increased by the subsequent supply of biomass fuel for combustion. During the ignition process, heat gradually accumulates, allowing more fuel to participate in the reaction, and the temperature also increases accordingly. When the temperature reaches above 800 degrees Celsius, it can burn well.
Fuel combustion has a certain speed, reaching a certain degree of combustion requires a certain amount of time for complete combustion. Combustion adjustment is to maintain the residence time of combustion in the furnace as much as possible. Only with sufficient combustion time can complete combustion be achieved.
If the air volume is too low, the combustible components cannot be fully burned, resulting in incomplete combustion losses; But if the air volume is too high, it will lower the temperature of the combustion chamber, affect the degree of complete combustion, and also cause a large amount of flue gas, reducing the thermal effect of the boiler burner. One gust of wind is enough to blow, penetrate, and stir the fuel; The secondary air is strong and enters quickly, and there should be no lack of oxygen during intense combustion. In the upper combustion zone of the furnace, sufficient oxygen needs to be maintained.
In fact, sometimes what seems ordinary to us is precisely where the problem lies. The simple truth is that for boiler burners, the factors that generally affect their normal operation are like this.
