摘　　要：运用平衡计算法建立了城市生活垃圾焚烧炉模型，并分别对我国6座城市原生垃圾的掺煤燃烧（垃圾与煤的掺烧比为9）进行了模拟计算和特性分析。结果表明，采用焚烧处理我国城市生活垃圾，焚烧炉预热空气温度应不低于100℃，空气过剩系数应为1．2～1．3，大型城市垃圾含水率应不大于10％，而中小型城市垃圾含水率可适当提高到10％～20％，方能获得较高的绝热火焰温度（〉800℃）。In the present paper, the modeling of mixing-firing of the municipal solid wast and coal （the ratio of MSW to coal was 9） was established by equilibrium calculations. The combustion of the wastes coming from the six cities in our country was simulated and the combustion characteristics of them were analyzed. The results showed that in order to obtain high temperature （〉800 ℃） when incinerating wastes of our country, the temperature of preheated air should be not more than 100℃, excess-air coefficient should be 1.2-1.3, moisture content of waste should be not above 10 % in the big cities and should be 10 % -20 % in medium-sized city and town.
