摘　　要：基于煤燃烧过程中矿物质蒸发、凝聚和沉积的机理，在理论和实验上对三种不同结渣和沾污特性的煤进行了研究；综合煤的化学组成和锅炉燃烧运行工况对煤灰沉积特性的影响，提出了一种新的结渣和沾污判定指数。Based on the mechanisms of evaporation,condensation and deposit of minerals duringcoal combustion, the deposit tendency including that of slagging and fouling of various kindsof coal has been theoretically and experimentally studied.New indices for slagging and foul-ing are proposed by taking into account the effects of both the chemical composition of thecoal ash and the combustion conditions on the ash deposit.

关 键 词：煤 燃烧 煤灰 沉积 判定指数
