在民用采暖及供热上,铸铁锅炉是最常用的一种设备。可是到目前为止,在我国使用的铸铁锅炉,几乎全部都是旧式的内火炉。1954年沈阳暖气器材厂学习苏联先进经验试制成功了火焰式铸铁锅炉,最近北京暖气材料厂又试制成功了火焰式铸铁锅炉及万能式铸铁锅炉。这两种铸铁锅炉都是苏联比较新式的片式锅炉,它们部是外火炉,都可以用作蒸气锅炉,也能作为热水锅炉。作为蒸汽锅炉时于锅炉片上部另设一汽水筒(俗称汽色),给台水进入汽水筒,然后再经过前后四根下降的循环水管流人锅炉片。由锅炉片中发生的蒸汽随着受热的水,经前后两根上升的循环水管流回汽水筒,在汽水筒中汽水分离,蒸汽由汽水筒上部出汽口输出,作为热水锅炉时,则不须
For civil heating and heating, cast iron boilers are the most commonly used equipment. But so far, the cast iron boilers used in our country are almost all old-style internal furnaces. In 1954, Shenyang Heating Equipment Factory learned the advanced experience of the Soviet Union and successfully produced a flame-type cast iron boiler. Recently, the Beijing Heating Material Factory successfully implemented a flame-type cast iron boiler and a universal cast iron boiler. These two types of cast iron boilers are relatively new types of Soviet-style boilers. They are external furnaces and can be used as steam boilers or as hot water boilers. As a steam boiler, a steam cylinder (commonly known as a steam color) is installed at the top of the boiler plate to feed the water into the steam water tank, and then through the four lower circulating water pipes to flow into the boiler plate. The steam generated in the boiler plate flows back to the steam drum with the heated water pipes as the heated water flows. The steam and water are separated in the steam drum, and the steam is output from the steam outlet at the upper part of the steam cylinder. When it is used as a hot water boiler, Not required
