The melting points in the fermentor are 870 ℃ and 760 ℃, respectively. Low viscosity eutectic adheres to the sand surface and combines with each other to form caking phenomenon. In the laminar combustion boiler, the combustion temperature is higher than the ash melting point of biomass fuel (the ash melting point is as low as 1000 ℃), and the slag is easy to be broken. The content of S element in the biomass emitted by harmful gases is usually low, but some SO2 gases can still be detected in the exhaust emissions.

However, in the process of biomass combustion, the emission of HCl is much higher than that of coal, which is mainly due to the high chlorine content in biomass. These emissions further react with the potassium element of the biomaterial towel and are prone to form gaseous solutions.

Aerosol emission in the atmosphere will cause environmental pollution, and it is also easy to adhere to the catalyst surface (such as SCR), affecting the role of catalyst. In terms of quality calibration, the N content of biomass is less than that of coal, but due to the low calorific value of biomass, the N content of biomass is the same as that of coal, because the calorific value of biomass is low.

Due to the combustion temperature of the fluidized bed, after the high waterfall cyclone separator, ammonia injection denitrification measures can be more convenient to meet the strict requirements of 100mg / m3nox emission.
