Many customers who use pine wood pellet fuel for the first time do not understand the combustion conditions of biomass pellet fuel. The following summarizes the problems that often encounter biomass pellet fuels as follows:

Answer: First of all, we need to know what pine pellet fuel needs to be fully burned. According to the characteristics of biomass fuel, pine pellet fuel generally needs to be gasified to form secondary combustion of combustible gas, so there is a high enough temperature in the boiler to gasify the pine pellet fuel. Only when the furnace temperature reaches a high enough can the pine pellet fuel be gasified and the combustible gas is formed to achieve secondary combustion. Therefore, whether pine pellet fuel can be fully burned is proportional to the stability of the boiler, and try to ensure that the furnace temperature is high enough.

Secondly, the combustion of pine pellet fuel requires a large amount of oxygen to achieve oxygen-rich combustion after gasification. The combustion of pine pellet fuel is different from coal-fired. Coal does not require a large amount of air to help combustion, while pine pellet fuel requires a large amount of air to increase the volatility of the fuel, forming a full combustion of oxygen-rich gasification. There are also some considerations for increasing oxygen. If cold air is blown in, first, the temperature of the combustion chamber is lowered, which is not conducive to high-temperature combustion. Second, the cold air reduces the temperature and wastes more fuel to increase the furnace temperature, so it is recommended to blow hot air.

Regarding coking, this is related to whether the pine pellet fuel can be fully burned. Only when the furnace temperature is high and the oxygen is sufficient, the occurrence of coking can be reduced. In addition, high-quality pine wood pellet fuel is also necessary to burn high ash and have high calorific value to reduce the degree of coking and the probability of occurrence. Please see the flame ejected after the biomass burns fully.

Now let’s take a look at the problem of how pine pellet fuel is fully burned without coking. In fact, as long as you choose the right pine pellet fuel and burn in a suitable biomass combustion equipment such as a biomass boiler or biomass burner, the full combustion of pine pellet fuel can be achieved.
