一、慨况略阳电厂第一期工程 1、2号炉为四角燃烧的130吨/时中压煤粉炉。每炉各配3台φ1600×600风扇磨煤机。第二期工程3号炉为四角燃烧的220吨/时高压煤粉炉,配5台φ1600×600风扇磨煤机。77年所用的铜川煤:A~y～35％;W~y～5％;V~R～25％;Q~y～4500大卡/公斤。这些风扇磨的叶轮都是一样的,但在3号炉的风扇磨上进行了改装(以下简称B型),其蜗壳结构与1、2号炉的(以下简称A型)不同,它们的主要尺寸分别如图1所示。
First, the situation Slightly the first phase of power plant 1,2 furnace for the four corners of the 130 tonne / hour medium pressure pulverized coal fired furnace. Each furnace with 3 sets of φ1600 × 600 fan coal mill. The second phase of the project No. 3 furnace for the four corners of the burning 220 tons / hour high pressure pulverized coal furnace, with 5 sets of φ 1600 × 600 fan coal mill. 77 Tongchuan coal used: A ~ y ~ 35%; W ~ y ~ 5%; V ~ R ~ 25%; Q ~ y ~ 4500 kcal / kg. The impeller for these fan mills is the same, but was retrofitted on the fan mills of furnace No.3 (hereinafter referred to as Type B). The volute structure is different from that of No.1 and No.2 furnaces (hereinafter referred to as Type A) The main dimensions are shown in Figure 1.
