我国电力系统中,用电负荷峰谷差愈来愈大,小机组的调峰已远远满足不了要求,这就要求大型机组参加调峰,以解决峰谷差大的矛盾。大型机组的调峰的突出问题是锅炉的低负荷稳定燃烧;同时助燃用油紧缺,并成为电厂一笔很大的开支。因此大型锅炉的低负荷稳定运行和节省低负荷的助燃用油必须同时考虑。近年来,相继研制成功各种型式的预燃室和新型燃烧器,对调峰节油起了很大作用。我厂于1989年11月在3号炉
In China’s power system, the peak-to-valley difference of the electricity load is more and more large, and the peak regulation of small units can not meet the requirements far, which requires the large units to participate in the peak-shaving in order to solve the contradiction between the large peak and the valley. The prominent problem of the peak regulation of large units is the stable combustion of the boilers at a low load; at the same time, the combustion-supporting oil is in short supply and becomes a big expense for the power plant. Therefore, the stable operation of low-load large-scale boilers and low-load fuel-saving oil must be considered at the same time. In recent years, have successfully developed various types of pre-combustion chamber and a new type of burner, peaking plays a significant role. I plant in November 1989 in the 3rd furnace
