为节约锅炉点火和助燃用油,多年来,高等院校、科研单位和电厂为锅炉少油点火,无油点火和以煤代油方面进行了大量的研究,做了不少试验,各种预燃室和新型喷燃器的试验成功,为电厂锅炉节油起到了一定作用。为加快锅炉节油方面的研究,提高锅炉在低负荷下的稳燃能力,现提出在贮仓式制粉系统锅炉上采用再热部分一次风输粉的节油方案,供同行探讨。 In order to save boiler ignition and combustion-supporting oil, for many years, universities, research institutes and power plants have done a lot of research on boiler oil-less ignition, oil-free ignition and coal substitution. Many tests have been done, The successful test of the combustion chamber and the new burner has played a role in saving fuel for power plant boilers. In order to speed up the research of boiler fuel economy and improve the stable combustion ability of the boiler under low load, a fuel saving solution of using primary reheat part of wind powder transportation on the boiler of a silo system for pulverized coal injection is proposed for peer discussion.
