洗选煤

燃用洗选煤是解决锅炉污染的经济有效方法

Economic and Effective Method for Solving Pollution of Boiler-Burning Washed Coal

结果表明工业锅炉燃用洗选煤与锅炉改造配合，可提高锅炉效率5%～10%，减少污染物排放30%～50%，运行成本变化不大，适宜在广大中小城市广泛应用。

Study result is shown that , boiler efficiency increasing 5 % ~ 10 % , pollution emission decreasing 30 % ~ 50 % , operation cost without changed if adopted to burn washed coal and boiler transformation . This method may widely use in middle and small cities .

据此提出了利用气流分级技术开发脱粉入洗选煤工艺。

The coal preparation technology after fines removal that using the air-stream classification technique is put forward .

对我国煤炭效率低、污染排放严重的状况进行了分析和探讨，指出要改善燃烧现状，须在大力发展洗选煤的同时，积极发展动力配煤技术。

This paper analyses and discusses on the situation of low coal combustion efficiency and serious pollution in our country pointing out that we must develop dynamic coal blending techniques actively while developing coal washing energetically .

有发展潜力的汞控制方法有3种：常规物理洗选煤技术、现有污染物控制装置和烟气中喷入活性炭等吸附剂方式。

There are three methods which have potential of development for controlling mercury , namely the common physical coal cleaning technology , existing pollutant control facilities , and injecting sorbent , such as activated carbon etc. , into the flue gas .
