25  ℃ /  min。  The  results  also  showed that  three  kinds  of  raw material  bamboo shavings

combustion performance of the best, followed by sawdust, rice husk of poor combustion performance。

Second, determine the size and heating rate after five experiments using three different blending ratio of raw material to the experimental study of combustion mixing。 Experimental results show that the addition of biomass greatly improve the overall performance of coal combustion, biomass combustion characteristics significantly better than coal, the ignition temperature of the mixture of coal and biomass combustion ignition temperature approaching。 With the blending ratio increases, the ignition temperature and burn mixed coal combustion temperature decreases。 Integrated Combustion Characteristics of bituminous coal and anthracite separate combustion index was 5。70 × 10-7  and 2。50 × 10-7, with coal and    biomass

blending ratio increases, the composite index of the combustion characteristics linear increase in biomass and pulverized coal blending ratio of 1: 1, the raw material for pulverized coal promote more obvious。 Different types of biomass and coal co-combustion of coal combustion characteristics can be improved, but the degree of improvement is inconsistent different biomass to coal。 At the same heating rate, when the blending ratio of 1: 1, the maximum value of two kinds of biomass co-firing pulverized coal blended combustion characteristics of composite indices are: bamboo shavings and co-firing bituminous coal combustion characteristics comprehensive index was 7。93 × 10-6, sawdust mixed with anthracite-fired combined combustion characteristics 4。25 × 10-5。 Therefore pulverized by the respective optimum blend of biomass。 Shenhua bituminous corresponds bamboo  shavings, and sawdust Yangquan anthracite corresponds。
