Использование биомассы (биоотходов) в качестве возобновляемого источника энергии, представляет большой интерес с точки зрения экологии и защиты окружающей среды. Однако при сжигании биомассы в топках с кипящем слоем наблюдается ряд проблем: коррозия конвективных поверхностей нагрева котлов, агломерация частиц инертного материала и золы биомассы, дефлюидизация и др.

Рассмотрены характерные проблемы сжигания различных отходов растениеводства и, в частности, лузги подсолнечника, так как этот вид биоотходов очень распространен в России.

Определены пути решения проблемы, позволяющие уменьшить риск коррозионных разрушений поверхностей нагрева котлов, улучшить топливные и эксплуатационные характеристики биомассы. К ним относятся предварительная промывка биомассы горячей водой, торрефикация, рациональный выбор материалов кипящего слоя и ряд других.

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.
