一、概述 在我国农村大部分地区,农民炊事主要使用农作物秸秆。据统计,仅黑龙江省1998年就有2600万吨农作物秸秆被农民烧掉,占全省当年秸秆总产量的58％。秸秆直接燃烧利用,不仅热效率低,污染严重,而且劳动强度大,影响环境卫生,易发生火灾。同时受我国自然资源条件和农村经济发展水平的限制,农村地区不能象城市一样大量使用煤、油、电、燃气等商品能源,而秸秆气化集中供气技术的出现解决了这一难题。秸秆气化是以农村丰富的农作物 First, an overview In most parts of rural China, farmer cooking mainly uses crop straws. According to statistics, only 26 million tons of crop straw were burned by farmers in Heilongjiang Province in 1998, accounting for 58% of the total output of straw in that year. Straw direct combustion and utilization, not only low thermal efficiency, serious pollution, but also labor-intensive, affecting environmental health, prone to fire. At the same time, due to the restriction of the natural resource conditions and the level of rural economic development in our country, rural areas can not use as much coal, oil, electricity, gas and other commodity energy as the cities, and the emergence of straw gasification centralized gas supply solves this problem. Straw gasification is based on rich rural crops
