The combustion characteristics of coal is very complex in cement industry, the traditional coal assessment can′t be applied to evaluate it. In this paper, a new kind of coal assessment including burning intensity (I), average heating capacity (Q) and general burning index (S) has been investigated. This evaluation method is combined with furnace types of cement industry on the basis of thermal analysis tests of 60 kinds of bituminous coal and anthracite. Experimental results showed that one kind of coal with higher S, lower I and higher Q should be regarded as an ideal coal from the viewpoint of cement industry. The quantitative index is showed to the bituminous coal and anthracite in this paper. This assessment method is beneficial to the design of furnace.

According to the dynamics of gas－solid packed beds, a mathematical model of cooling air flow in vertical cooler is established in this article. Distributing of velocity field and resistance in cooler is simulated by JAVA program. And basic flowing rules of cooling air are studied under different air speed. The affect of velocity for velocity field and resistance of clinker are discussed here. The results indicate that air speed has a great influence on air flow in vertical cooler. Unit resistance of clinker is linear essentially with velocity when the air speed is ＜9m／s; And yet unit resistance of clinker is the quadratic function of air speed when the velocity is ＞9m／s. Resistance of clinker is the quadratic function of porosity. The effect of the clinker  size on flow field is less than clinker porosity.

According to the statistical figures of China＇s cement production in 2001～2006,a grey forecast model on GM (1,1) in cement production was established. The results show that prediction model has higher accuracy, cement production  presents increasing　trend　in　future　three　years.

Waste heat power generation is an effective way in energy saving and power reduction in cement industry． Providing accurate thermal parameter for waste heat power generation is the important prerequisite for designing a power generation system． So it is very important to do thermal test on waste gas parameters． In this paper, the determination of waste gas parameter for the SP and AQC exhaust heat boilers were discussed．
