一、概况根据国家有关部门下达压油烧煤的精神,我厂将6台烧油11t/h炉(原列电锅炉)和5台供热用小锅炉停用,改装2台35t/h链条炉,供发电与全厂用汽,运行二年来暴露出一些问题,例如出力不足,过热蒸汽超温,燃用本省煤着火难等。为进一步了解锅炉性能,並为解决上述问题提供必要的依据,我们进行了热效率测 I. Overview According to the spirit issued by the relevant state departments for pressure oil burning and coal burning, the plant will be 6 sets of oil burning 11t / h furnace (the original electric boiler) and 5 small boilers for heating disabled, modified 2 sets of 35t / h chain Furnace, for power generation and the whole plant with steam, running two years to expose some problems, such as lack of output, overheated steam over-temperature, burning the provincial coal fire and so on. In order to further understand the boiler performance, and to provide the necessary basis to solve the above problems, we conducted a thermal efficiency test
