目前电站锅炉运行中的一个现实问题,是设法不切除燃烧器而扩大锅炉负荷的调节范围。调节范围决定于重油压力的下限,并和燃烧器结构、炉膛热负荷和其他因素有关。根据所作的试验来看,塔干罗克锅炉厂ΤΓΜΠ-114型锅炉(配30万瓩机组)能在12.5～30万瓩很宽的负荷范围内稳定和可靠地运行。但是由于重油压力较低P_m=12～15公斤/厘米~2,当采用现有的机械雾化喷嘴和过量空气系数α=1.06时,锅炉最低负荷只能达到20万瓩。ΤΓΜΠ-114锅炉上最早装的是巴什基尔电业局所属CHAΤ设计的机械雾化喷嘴。在额定负荷时喷嘴前的重油工作压力为37～40
A practical problem in the operation of utility boilers at present is to find ways to expand the boiler load regulation without removing the burner. The adjustment range is based on the lower limit of heavy oil pressure and is related to the burner structure, furnace heat load and other factors. According to the tests conducted, the TARNK-114 boiler (equipped with 300,000 units) of TARANROOK boiler plant can operate stably and reliably over a wide load range of 12.5 to 300,000 瓩. However, due to the lower heavy oil pressure P_m = 12-15 kg / cm ~ 2, the minimum load of the boiler can only reach 200,000 当 when using the existing mechanical atomization nozzle and the excess air ratio α = 1.06. The earliest installation on the ΤΓΜΠ-114 boiler was the mechanical atomization nozzle designed by CHATI, a division of the Bashkir Electrical Authority. In the rated load before the nozzle of heavy oil working pressure of 37 ~ 40
