How to reduce the generation of combustible matter in fly ash in biomass-fired boiler fuel?

After combustion, biomass-fired boiler fuel will generate energy and also produce some combustible matter in fly ash which will have bad influence on the surrounding environment. Therefore, in order to realize the goal of environmental protection, we should reduce the generation of combustible matter in fly ash in biomass-fired boiler fuel.

Reducing the generation of combustible matter in fly ash should realize the sufficient combustion of biomass-fired boiler fuel. On one hand, we should appropriately increase the hot air in the outlet of boiler's air preheater; on the other hand, we should strengthen the maintenance of burner to promote the sufficient combustion of boiler fuel.

Due to the bad working environment of biomass-fired boiler's burner, only strengthening the maintenance can ensure the equipment in good condition. As a result, we can take advantage of the furnace shut down time to carefully check the burner and repair it timely.

In addition, if we can strengthen the ignition control in boiler's combustion, we should control the ignition distance of fuel. According to the ignition and tempering conditions of pulverized coal, we should adjust the opening of air door timely to improve the combustion efficiency to some extent.

When the biomass-fired boiler is under high or low load working conditions, we should adjust the fuel combustion and the ratio of primary air and second air to ensure that the flame is in the right position of furnace and that fuel mixes well with the air for fuel's sufficient combustion.

The complete combustion of fuel in the biomass-fired boiler can improve the fuel use ratio and control the generation of combustible matter in fly ash, so as to realize the goal of environmental protection.
