Abstract：

To improve the utilization of steam coal,analyze the coal properties of different types and the main coal-producing areas. Provide the carbon capture and storage( CCS) strategy to reduce the increasingly CO2 emissions caused by coal combustion. Introduce some CCS projects in China. The ash of weakly caking coal is the lowest with 13. 10%,the calorific value is the highest with 29. 59 MJ /kg. The ash and sulfur of meager coal is the highest,while its moisture and volatile is lower. The lignite,with the lowest moisture,calorific value and highest moisture and volatile,is mainly used to generate power,then gasification and synthesis. The steam coal is mainly used to generate power,then boiler combustion. The long flame coal provides energy for power plant,locomotive and furnace. Non-caking coal and weakly caking coal generate power and provide fuel for civil use. The CCS is an important method to reduce the CO2 emissions and mitigate the greenhouse effect.

Key Words： steam coal;coal property;carbon capture and storage(CCS);power generation;CO2 emission
