The difference of element content between biomass fuel and coal is summarized
the mechanisms of ash accumulation
slagging and corrosion of biomass boilers are analyzed
and the characteristics of flue gas of biomass boilers are combed. Moreover
the limitations of selective non-catalytic reduction technology
selective catalytic reduction technology and wet flue gas desulfurization technology in the application of biomass power plants are discussed and summarized. The results show that
both the solid-state polymer NCR denitrification and sulfurnitrogen integrated removal using catalyst require special catalysts or denitrification agents
which are patented products and have high operating costs. The oxidation denitrification technology is oxidation absorption reaction
which produces nitrates that is soluble in water
this technology is prohibited in some areas. The ceramic catalytic filter tube integrated removal technology is simple to operate and maintain
of which the over-oxygen combustion of the boiler can improve the combustion efficiency and prolong the service life of air preheater. Moreover
there is no desulfurization wastewater
chimney corrosion
white plume and other related issues. Therefore
it is a more suitable for ultra-low emission of biomass boilers.
