5. Biomass Conversion Technologies

Biomass boiler dusts tend to stick to the heat transfer surfaces and form hard deposits when they are between T15 and T70. An example showing the effect of water content on material behaviour is plaster. If it is dry, it will fall off the wall. If there is too much water the plaster will again fall off the wall.
