中国城市入炉生活垃圾热值分析

为分析垃圾热值与地理区域、季节、年份等的关系,选取国内有代表性的46座城市生活垃圾焚烧发电厂为研究对象,在收集和整理大量运营数据后,计算得到入炉生活垃圾的热值。研究结果表明:南方地区垃圾热值普遍高于北方,东南沿海经济发达地区的城市生活垃圾热值最高,其中广东、江苏和浙江入炉垃圾热值均在7 400 kJ/kg以上;四季分明的城市,春季和冬季城市生活垃圾热值明显低于夏季和秋季,不同季节入炉垃圾的热值最大相差8% ~ 22%;各城市生活垃圾热值逐年增长。

Analysis on Calorific Value of Municipal Solid Waste as Fired in China

In order to analyze the impact of the factors including geographical region, season, year on the calorific value of municipal solid waste (MSW), 46 representative MSW incineration power plants in China were selected as the research objects. After collecting and sorting out lots of operational data of MSW incineration power plant, the calorific value of MSW was calculated. The results show that: the calorific value of MSW in the south is generally higher than that in the north; the calorific value of MSW is the highest in the southeast coastal developed areas, among which the calorific value of MSW in Guangdong, Jiangsu and Zhejiang are all above 7 400 kJ/kg. In cities with four distinct seasons, the calorific value of MSW in spring and winter is obviously lower than that in summer and autumn, and the maximum difference of the calorific value in different seasons varied by 8%-22%; the calorific value of MSW increases year by year.
