摘  要:
介绍了泥炭腐植酸类物质用作水煤浆添加剂和型煤粘结剂的理论基础和实际应用效果。结果表明,将泥炭中含有的大量腐植酸类物质经过改性,用作水煤浆添加剂,在新汶煤、八一煤、邢台煤、兖州煤、鹤岗煤、抚顺煤、神华煤、双鸭山煤等煤种上使用,制浆浓度在65%~69%,粘度在1000mPa·s左右;用作型煤粘结剂,添加量在7%~10%,单个球的冷强度为55~88kg,热强度为50~70kg,常温下耐水性好,对灰分无增加,对环境无污染。

摘  要:
Clean coal technology is one of the importantenergy development strategies in China. This paperintroduces the theoretic basis and practical use effects ofhumic acid substance used as the additives for coal watermixture(CWM) and briquette binder are introduced. Theresults show that the humic acid substance in peat, aftermodification, was changed their properties and used as theadditives for CWM on the different kinds of coal, such asXinwen, Bayi, Xingtai, Yanzhou, Hegang, Fushun, Shenhuaand Shuangyashan, the concentration of CWM is 65%~69%while the viscosity is about 1000 mPa?s. Moreover, thehumic acid substance was oxided and used as briquettebinder. When the content of additive is 7%~10% of coalweight, the cool strength of a briquette is 55~88 kg, and hotstrength is 50~70 kg. The briquette binder is water stableunder normal temperature, introduced little ash and littlepollute into the briquette.
