农机部第二设计研究院与天津重型机器厂、洛阳拖拉机厂、天津机车车辆厂三个单位协力攻关,研制了“发生炉煤气平焰烧咀”、“普通碳钢辐射换热器”,并于四月份由农机部在天津召开的鉴定会上予以通过。目前,我国机械工业一些中,大型工厂使用低热值发生炉煤气作为各种加热的热源普遍存在着炉温低、升温速度慢、金属氧化 The Second Design and Research Institute of the Ministry of Agriculture and the Tianjin Heavy Machinery Plant, Luoyang Tractor Factory, Tianjin Locomotive Works three units to tackle the problem, developed a “gas burner Pingzhuozui”, “ordinary carbon steel radiation heat exchanger” and In April by the Ministry of Agriculture held in Tianjin appraisal meeting be passed. At present, some of China’s machinery industry, large factories using low-calorific value furnace gas as a heat source of a variety of widespread prevalence of low temperature, slow heating, metal oxidation
