几十年来,世界许多国家都大力发展铸铁锅炉。据苏联1985年介绍,尽管1981~1985年,直至1990年,应进一步发展集中供热系统,但仍继续建设铸铁锅炉小型锅炉房。苏联每年生产约5万台不同型式的铸铁锅炉,它约相当于苏联生产锅炉台数的40%,铸铁锅炉大约提供28%的热量。日本1974年,蒸汽锅炉总计生产95,809台,其中铸铁锅炉为20,032台,占23%;热水锅炉总计生产24,031台,其中铸铁锅炉为13,751台,占55.02%。
For decades, many countries in the world have made great efforts to develop cast iron boilers. According to the introduction by the Soviet Union in 1985, although the district heating system should be further developed from 1981 to 1985 and up to 1990, the small boiler house for cast iron boilers will continue to be built. The Soviet Union produces about 50,000 different types of cast iron boilers each year, which is about 40% of the number of boilers in the Soviet Union and about 28% in cast iron boilers. Japan In 1974, a total of 95,809 steam boilers were produced, of which 20,032 were cast iron boilers, accounting for 23%. A total of 24,031 hot water boilers were produced, of which 13,751 were cast iron boilers, accounting for 55.02%.
