Why does straw biomass fuel easily clog the return pipe/
Biomass fuel has very poor fluidity, so it is an important issue for the feeding system to ensure smooth material supply.
This is a common problem with poor fluidized bed combustion; a stable excess of air should be ensured.
Biomass fuels have a high content of alkali metals, low ash density and poor fluidity, which makes them prone to getting stuck in areas of the return pipe where the temperature is low; at low temperatures, alkali metals tend to precipitate out
