- 该发电锅炉(Steam boiler)主要目的为蒸气推动蒸气涡轮机(Steam turbine)曾用于南斯拉夫之Gatsko及Uglevik两地区的热动力厂。
- 此Ⅱn-1000-255(Ⅱ64) 型之锅炉设计燃烧在南斯拉夫使用品质较劣之褐煤(lignite),其褐煤之湿度为W=33to 44%,灰份(ASH)Aw自8% to 32%,含硫量(Scom)亦高达5.6%,可推动300MW之涡轮机(Steamboiler)。
- 该锅炉是一种Straigh-through;单燃烧炉之(Single furnace),且为一种doule-flue Supercritical-pressure reheat boiler。
- 这种锅炉(Steam boiler)规格如下:
