【摘要】 用微量热天平研究了煤焦油和重油的热解特性和燃烧特性,并在此基础上初步分析了用煤焦油代替重油作为动力燃料时应该注意的因素。结果显示,不能简单用煤焦油替代重油直接在重油燃烧器上燃烧,为了防止煤焦油中挥发份过早析出导致结焦积炭,进燃烧器之前煤焦油的加热应注意采用较低的加热温度和加热强度。更多还原

【Abstract】 The pyrolysis and combustion characteristics of coal tar and heavy oil are analyzed using thermobalance to study the factors needing attention for substituting the coal tar for the heavy oil as power fuel.The results show that the coal tar cannot be burned directly using the burner designed for heavy oil.In order to avoid agglomeration and char-accumulation resulting from the volatile matter of the coal tar liberating too early,the temperature and the intensity should be lower in heating the coal tar before entering into the burner.更多还原
