秸秆气化是以农作物秸秆、稻壳、木屑、树枝等为原料,经过粉碎送入气化炉中,在缺氧的状态下进行燃烧,通过控制燃烧过程,使之产生含一氧化碳、氢气、甲烷等可燃气体的木质气供用户使用。秸秆气化的过程是一个复杂的化学反应过程,根据目前的技术水平,一般每千克秸秆可产2～3立方米木质气,木质气热值为1000大卡/立方米左右,一个五口之家每天需5～6立方米木质气。 山西省晋中市杨盘村有农作物面积2500亩(其中玉米900亩,小麦1300亩,棉花300亩),占耕地面积的85％,全村每年平均可产玉米、小麦等农作物秸秆1200多吨。这些农作物的副产品,除每年有800吨用于还田养畜外,还有约400吨得不到有效利用而被露天焚烧,一方面使这些物质的有效元素(氮10.7
Straw gasification is based on crop straw, rice husk, sawdust, branches and other raw materials, crushed into the gasifier, the state of oxygen in the combustion under the control of the combustion process to produce carbon monoxide, hydrogen, methane Wood gas such as combustible gas for users to use. The process of straw gasification is a complex chemical reaction process. According to the current technical level, generally 2 to 3 cubic meters of woody gas can be produced per kilogram of straw, and the value of wood gas calorific value is about 1000 kcal / cubic meter. A five- Home every day 5 to 6 cubic meters of wood gas. In Yangpan Village, Jinzhong City, Shanxi Province, there are 2,500 mu of crops (including 900 mu of corn, 1,300 mu of wheat and 300 mu of cotton), accounting for 85% of the cultivated land area. The average annual production of corn and wheat crop straws in the village is over 1,200 tons . The by-products of these crops, in addition to 800 tonnes annually for returning livestock, are burned in the open for about 400 tonnes of unavailability of effective utilization and on the one hand make available the effective elements of these substances (N 10.7
