How to solve the slagging of biomass boilers?

Sometimes the biomass fuels are distributed unevenly in boilers. They become high temperature combustion mass and burn with insufficient oxygen which will cause slagging. Insufficient ventilation quantity will increase the slagging degree. Therefore to avoid biomass boiler slagging you should control the proportion of fuel and air.
