On the Technology of Increasing the Efficiency and Reliability of Boilers Burning Biowaste in a Fluidized Bed of Inert Material

The use of biomass (biowaste) as a renewable energy source is of great interest from the point of view of ecology and environmental protection. However, when burning biomass in fluidized bed furnaces, a number of problems are observed: corrosion of convective heating surfaces of boilers, agglomeration of particles of inert material and biomass ash, defluidization, etc.

The article considers the characteristic problems of burning various plant wastes and, in particular, sunflower husks, since this type of biowaste is very common in Russia.

The ways of solving problems that reduce the risk of corrosion damage to boiler heating surfaces, improve the fuel and operational characteristics of biomass are determined. These include preliminary washing of biomass with hot water, torrefaction, rational selection of fluidized bed materials, and a number of others.
