Co-combustion of agriculture and forest residues with pulverized coal provides a promising way to generate power more environmentally-friendly and economically.In this paper

rice husk was co-combusted with a bituminous coal and a lignite respectively.A non-isothermal thermogravimetric method was adopted to investigate the combustion characteristics of various coal/biomass blends at heating rate of 10 ℃/min from 100 ℃ to 1 000 ℃.The results show that

the addition of rice husk improved the bituminous coal combustion

and this effect seemed to be enhanced by increasing the proportion of rice husk.In contrast

no significant interactions were observed in combustion of lignite/rice husk blends.Therefore

in the actual cocombustion of rice husk with coal

the combustion performance should be evaluated based on the type of the coal used.
