煤是我国的主要能源,工业锅炉每年约用掉全国原煤产量的三分之一,我国工业锅炉本体设计的热效率与世界发达国家比较接近,但是,由于自动化水平低,人工控制受人的因素影响比较大,造成大部分工业锅炉的实际运行效率大大低于设计值,以10吨/小时燃煤锅炉为例,一般只有60～65%,而10吨/小时以下的锅炉效率更低。近年来,随着微机技术的普及和推广,国内外都在用微机控制来提高锅炉的运行效率和蒸汽品质,减少环境污染。国内对链条炉的微机控制系统已有多篇报导,取得了比较满意的效果。工业沸腾锅炉有其独特的燃烧方式,它采用沸腾燃烧,可烧其他锅炉不能使用的低热值煤、劣质煤、煤矸石,有益于我国煤资源的合理使用。对优质煤缺乏的南方,它能缓和对能源需求的矛盾,这种燃烧方式也为解决粉尘和酸雨污染提供了方便条件。因为沸腾
Coal is the main energy source in our country. The annual output of industrial boilers consumes about one-third of the country’s total output of raw coal. The thermal efficiency of industrial boilers in China is relatively close to that of the developed countries in the world. However, due to the low level of automation, The actual operating efficiency of most industrial boilers is much lower than the designed value. Taking a 10 t / h coal-fired boiler as an example, it is generally only 60-65%, while the boilers of less than 10 t / h are less efficient. In recent years, with the popularization and popularization of microcomputer technology, microcomputer control is used at home and abroad to improve the boiler operating efficiency and steam quality and reduce environmental pollution. Domestic chain furnace computer control system has been more than reported, and achieved satisfactory results. Boiling industry has its own unique way of burning, which uses boiling combustion, can be burned other boilers can not use low calorific value coal, low-grade coal, coal gangue, beneficial to the rational use of coal resources in China. In the South, where high-quality coal is scarce, it mitigates the contradiction between energy needs and provides a convenient way to address dust and acid rain pollution. Because of boiling
