我国工业部门使用不少仿造的旧式工业锅炉,它们热效率低,耗煤量大,被称为“煤老虎”,不适应社会主义建设事业飞跃发展的需要。在无产阶级文化大革命和批林批孔运动的有力推动下,不少地区和部门遵照毛主席“独立自主,自力更生”和“要提倡勤俭建国”的教导,打破洋框框,广泛发动群众改造旧式低效率锅炉,创造了许多好经验。黑龙江省绥化地区各县和吉林省怀德县开展的土法改造锅炉,就是一种有效的办法,值 China’s industrial sector uses a lot of old-fashioned industrial boilers. They have low thermal efficiency and large coal consumption. They are called “coal tigers” and do not meet the need for rapid development of socialist construction. Under the strong promotion of the proletarian cultural revolution and the approval of the Lin Piao and Confucius Movement, many localities and departments have broken the foreign framework in accordance with Chairman Mao’s guidance of “independent, self-reliant, and self-reliant” and “promoting diligence and building a country” and extensively mobilize the masses to transform old-style inefficiencies. The boiler has created many good experiences. The method of reforming the boilers in the soils of counties in the Suihua region of Heilongjiang Province and Huaide County of Jilin Province is an effective method.
