In view of the problems and difficulties during biomass application in the power plants

a new kind of biomass fuel blended with small proportion of pulverized coal was put forward

and experiments were carried out to study the fuel's combustion characteristics.Moreover

the pollutant emission model of the fuel was also established.The results show that

the maximum combustion rate of the fuel occurred in early period of the combustion phase.The high volatile content and reaction rate of the fuel improved the combustion

burnout and pollutant emission characteristics

the NO_x emission concentration reduced dramatically.The established pollutant emission model can be used to predict the emissions under different combustion conditions.The experimental results can provide theoretical basis and reference for co-firing biomass and coals in thermal power units.
