Why is insufficient combustion of biomass fuels in boilers

Boiler biomass fuel power is a renewable power made from agricultural and forestry wastes. It is easy to obtain, clean, environmentally friendly and convenient to transport. It can achieve "zero" carbon emission in a cycle. It is not bound by time, climate and region. It has low pollutant emission, green, energy-saving, environmental protection, cost-saving and easy to use.

The biomass fuel used in boilers is combustible, and the ash and slag are blackened. Assuming that raw material will be swept away when the combustion is insufficient, what are the factors causing the insufficient combustion of biomass fuel used in boilers?

1.The moisture content of biomass fuels used in boilers is too high, and it is difficult to ensure the normal combustion of fuels whose moisture content exceeds 45%.
2.The biomass fuel particles used in boilers are too large, which is not conducive to the combustion reaction.
3.The reaction time of biomass fuel combustion in boilers is not acceptable. The flutter of grate is too large, the interval is too short, and the combustion time is too short.
4.The ash content of biomass fuels used in boilers is too high. Coke particles are wrapped in ash, which makes the combustion rate slow.
5.Boiler uses too much biomass fuel to feed, and the burden layer on grate is too thick, which will also slow the combustion rate.
6.Abnormal events occurred in biomass boilers.
7.Boiler operators can not understand the nature of biomass fuels used in boilers, and can not grasp the combustion and distribution of fuel in the furnace in time. The combustion rules will not be adjusted by useful methods according to the combustion conditions.
