在贯彻执行国务院关于节约工业锅炉用煤的精神指导下,我市有许多单位已把小型(0.5～4T/H)蒸汽锅炉改为热水锅炉。仅我局自80年以来就改装了约60台。在合理利用能源、节约煤炭方面,起到了积极作用。但由于在改裝结构上的不合理,致使炉水的循环、对流受到极大的影响,经常造成局部过热,发生锅筒鼓包,烟火管、管板裂纹、爆管等事故,严重影响锅炉的安全运行,甚至不得不被迫停炉,给生产和生活带来损失。这些事故在全市各改裝锅炉的企业中也普遍存在,使节煤工作受到影响,其主要原因如下。 Guided by the spirit of the State Council on saving coal for industrial boilers, many units in our city have changed small (0.5-4T / H) steam boilers to hot water boilers. Only our bureau has converted about 60 units since 1980. In the rational use of energy, coal conservation has played a positive role. However, due to the unreasonable structure of the conversion, the circulation and convection of the boiler water are greatly affected. Local overheating is often caused. Accidents such as drum drum packs, pyrotechnic tubes, tube sheet cracks and squibs are seriously affected by the boiler safety Running, and even had to be forced to shutdown, bringing loss to production and life. These accidents in the city’s boiler modification enterprises are also widespread, so that coal saving work is affected, the main reason is as follows.
