在美国动力装置的耗能中,中小型工业锅炉的耗能竞高达40％,这是由于老式锅炉蒸发量小,热效率低所造成的。为此,自1972年世界能源危机以来,美国工业界就把老式锅炉的改造作为节能的重要措旋之一。 美国霍尼韦尔公司和通用汽车公司从事研究用微处理机改造工业锅炉。试验证明,采用微机控制燃烧系统,最佳节能效果可达20％,一般也可达5％。
In the United States power plant energy consumption, the energy consumption of small and medium-sized industrial boilers up to 40%, which is due to the old boiler evaporation, low thermal efficiency caused. To this end, since 1972, the world energy crisis, the United States put the old industrial boiler transformation as an important measure of energy conservation. Honeywell and General Motors of the United States engaged in research using microprocessors to transform industrial boilers. Experiments show that the use of computer-controlled combustion system, the best energy-saving effect of up to 20%, generally up to 5%.
