静态坩埚燃烧法探索新型煤粉助燃剂

Discovery on new combustion promoter of pulverized coal with static crucible combustion method

采用静态坩埚燃烧失重法对数十种试剂分别作为煤粉助燃剂进行实验研究,结果表明MnO2等多种传统助燃剂对煤粉燃烧的催化效果不及尿素、柠檬酸、偏钒酸铵等若干种文献中尚未研究和报道的新物质,因而认为这些物质具备作为高炉喷吹煤粉用新型助燃剂的潜力。

The combustion weight lost method with the static crucible was applied to the experiment study with over dozens of the reagents individually as the pulverized coal combustion promoter.The results showed that the catalytic results of the MnO2 and other several conventional combustion promoters would not be better than the urea,citric acid,ammonium metavanadate and other new materials not been studied and reported.Therefore those materials might have the potential as the new combustion promoter of the pulverized coal for the blast furnace.
