摘要
对中国贵州省不同类型的民用燃煤的CH4释放量进行了实际监测，得出了各自的CH4释放因子．并借此探讨了民用燃煤过程的CH4释放规律。根据民用燃煤情况；估算出1990年一年内中国和贵州省民用燃煤的CH4释放士分别为1．43Tg和0．06Tg。
Samples were taken of combustion gases released by burning of several typical types of coal in Guizhou, China. All the samples were analyzed for CH4, CO and CO2. Based on these data, we derived the CH4 emission factors corresponding to each type of coal and also discussed the principle of CH4 emission during residential coal-burning processes. According to coal combustion, CH4 emission from residential coal-burning was estimated at 1.43 Tg/a (Tg = 1012g) and 0. 06 Tg/a in 1990 for China and Guizhou, respectively.
