锅炉正压燃烧不仅严重恶化工作环境,而且对锅炉燃烧设备危害极大,经常造成故障停炉,影响生产生活的正常进行。目前我国工业锅炉普遍采用的是负压燃烧,负压值一般维持在2～3mmH_2O柱以内(阻力计算一般取2mmH_2O柱,即19.8Pa),然而实际运行过程中,很多工业锅炉不同程度地存在正压燃烧问题,轻的炉膛向外冒灰烟,污染车间环境,严重的则烧坏设备并可能烧
The positive pressure combustion of the boiler not only seriously deteriorates the working environment, but also greatly damages the boiler combustion equipment, often causing the shutdown of the furnace and affecting the normal production and life. At present, the common use of industrial boilers in our country is negative pressure combustion. The negative pressure value is generally maintained within 2 ~ 3mmH_2O column (resistance calculation generally takes 2mmH_2O column, that is, 19.8Pa). However, in actual operation, many industrial boilers exist to varying degrees Pressure burning problems, the light of the furnace out of the gray smoke, polluting the workshop environment, severe burn equipment and may burn
