目前,有关单位应用的10吨以下锅炉,因结构问题,只能使用单一类型的煤作燃料,如果所适用的煤断档,只好停用。如今这一难题已被攻克,10吨以下锅炉的“锅炉混合式炉拱及自控系统”问世。采用该项系统的锅炉,可以将固定式炉膛结构变为活动的可开闭炉拱,而且可以将手动炉拱变为自动控制和微机控制,从而改变了原来只能燃烧单一煤种为能够燃烧多种煤炭,并在高、低负荷时都能保持高的热效率,着火温控也十分灵敏,而且比原锅炉节煤10％左右。据上海有关专家教授鉴定,结论是达到国际先进水平,已获得上海市优秀发明选拔赛一等奖。
At present, the boilers of less than 10 tons used by the units concerned can only use a single type of coal as a fuel because of structural problems, and have to be deactivated if the applicable coal stalls. Now this problem has been overcome, the boiler below 10 tons of “boiler-type furnace arch and automatic control system” come out. The boiler with this system can turn the fixed hearth structure into an active openable and closable grate, and can turn the manual grate into automatic control and microcomputer control, thus changing the original can only burn a single coal to be able to burn A variety of coal, and at high and low load can maintain high thermal efficiency, ignition temperature control is also very sensitive, and about 10% coal saving than the original boiler. According to Shanghai experts and professors identified the conclusion is reached the international advanced level, has won the first prize of the Shanghai Excellent Invention Contest.
