Abstract
This demonstration project aims at reduction of pollutants derived from coal utilization in China by demonstration of CCT to be diffused in China and preparation of diffusion bases, and stable import of energy for Japan. A low-grade coal combustion system burns low-grade coal by use of an internal circulating fluidized bed boiler which burns coal by uniform mixing and circulation of coal and some particles such as limestone and ash. Main specifications of the boiler are as follows: evaporation rate of 35t/h, steam pressure of 3.82MPa (39.0kg/cm{sup 2}), steam temperature of 450degC, water supply temperature of 150degC, internal circulating fluidized bed combustion type, boiler efficiency of 75%, and desulfurization rate of 90% or more. Main properties of low-grade coal are as follows: calorific value of 1830kcal/kg, coal size of 10mm or less, total water content of 2.5%, total S content of 2.7%, ash content of 67.7%, limestone purity of 50% or more, and stone size of 3mm or less. The results in fiscal 1997 are as follows: field survey and arrangement, basic planning and design, design, production and procurement of equipment, training, and dispatch of field supervisor. 26 figs., 3 tabs.
