Because of slime with high moisture, high viscosity, high water holding capacity and low calorific value, and many other adverse conditions, it is difficult to achieve industrial applications, power users have long been shut to civilian ground pin for the main exit. Since the reform and opening up, with the rapid development of the national economy, coal production has leapt to the top of the world, the market situation has changed a lot. The depth and breadth of coal processing are rapidly developing, coal production increased significantly, slime utilization has become an urgent problem to be solved. Utilization of slime moisture smaller the better, slime slime CWS fluidized combustion or burning, water is not a chemical reaction in the combustion process, since only the physical changes, to participate in the combustion process has the following adverse effects of water. 1) at room temperature water to become 150 ℃ flue gas emissions, taking a number of heat, causing useless heat loss. 2) increase water, causing an increase in the amount of flue gas, resulting in an increase in the consumption of the boiler furnace and boiler flue section and steel, while the induced draft fan power to increase, leading to increased investment in infrastructure construction and operating costs. 3) increase fuel moisture causes the acid dew point of the flue gas increase, increasing the intensity of the low temperature corrosion tail heating surface.
