天津拖拉机制造厂最近試制成功一种新型煤气机。这就是24A型煤气机。它是一种用無烟煤(白煤)或木炭做燃料的动力机械。它分煤气發生爐和煤气發动机兩部分(圖1)。 將煤或木炭加到煤气發生爐內,从下部升火燃燒。燃料燃燒后就产生二氧化碳和一氧化碳。二氧化碳經过熾熱的燃料層又被还原成一氧化碳。同时燃料中的水分 The Tianjin Tractor Manufactory recently trial-produced a new type of gas engine. This is the 24A gas machine. It is a power machine that uses anthracite (white coal) or charcoal as fuel. It divides gas furnace and gas engine in two parts (Figure 1). Add coal or charcoal to the gas furnace and fire it from the lower part. After burning, carbon dioxide and carbon monoxide are produced. Carbon dioxide is reduced to carbon monoxide through a hot layer of fuel. At the same time the moisture in the fuel
