我国煤炭高效洁净利用新技术

煤炭的高效洁净利用是实现节能减排的有效途径,基于此,对我国目前煤炭高效洁净利用3项新技术（高效煤粉工业锅炉技术、水煤浆制备和应用新技术、活性焦干法烟气净化技术）的技术原理、创新点、技术优点及推广情况进行了介绍。结合当前实际,指出高效煤粉工业锅炉技术的发展方向是通过对清洁煤粉制备技术、煤粉物流配送技术、锅炉煤粉燃烧及净化技术以及商业化运营模式的深入系统化研究,最终建立高效煤粉工业锅炉技术体系。利用矿井水制备气化水煤浆并实现长距离管道运输,是气化水煤浆的发展方向。活性焦干法烟气净化技术适用于水资源缺乏地区,今后的发展方向是提高活性焦性能,降低工艺成本,提高脱硝能力,简化工艺流程,实现脱除和再生在一个装置内完成。

New Technology of Coal High Efficient and Cleaning Utilization in China

The high efficient and clean utilization of coal is the effective access to realize the energy saving and emission reduction.Based on the circumstances,the paper introduced the technical principle,innovations,technical advantage and promotion conditions of the three new technologies of the coal high efficient and clean utilization,including the high efficient pulverized coal industrial boiler technology,the coal water mixture preparation and new technology application and the dry flue gas cleaning technology of the active coke.In combination with the present actual conditions,the development orientation of the high efficient pulverized coal industrial boiler technology as pointed would be finally to set up the high efficient pulverized coal industrial boiler technology system with the deep systematic study on the clean pulverized coal preparation technology,the pulverized coal logistic and distribution technology,the pulverized coal boiler combustion and cleaning technology as well as the commercialized operation mode.The gasification coal water mixture prepared with the mine water and the long distance pipeline transportation would be the development orientation of the gasification coal water mixture.The dry flue gas cleaning technology of active coke would be suitable applied to the zone lacking of water resources and the development direction in the near future would be to improve the performances of the active coke,to reduce the technique cost,to improve the de-nitre capacity,to simplify the technique procedure and to have the removing and regeneration completed in a device.
