The boiler is π type outdoor arrangement supercritical boiler with variable pressure operation, single intermediate reheat, single furnace, balanced draft, dry ash removal and total steel frame suspending structure. It has atmospheric flash type startup system without recirculating pump and adopts tangential firing, low NOx bustion burners, 32 burners are arranged in 8 layers. The boiler is equipped with 8 units ZGM133NII medium speed mills directfired system of Beijing Power Equipment Group, under BMCR condition, 6 mills are in operation 2 mill is standby. 鍋爐以最大連續(xù)出力工況（ BMCR）為設(shè)計參數(shù)。在任何 6臺磨煤機運行時，鍋爐能長期帶 BMCR負荷運行。 Boiler takes maximum continuous rating (BMCR) as design parameter. When any 6 mills are operating the boiler can operate with BMCR load for long time. 機組設(shè)高、低壓兩級串連旁路系統(tǒng)，汽輪機旁路系統(tǒng)的容量暫按鍋爐 BMCR工況的60％設(shè)置；高低壓旁路包括蒸汽控制閥、減溫水控制閥和關(guān)斷閥以及控制裝置。 The unit has high pressure and low pressure twostage series bypass system, and capacity of bypass system of the turbine will be set temporarily based on 60% of BMCR working condition of boiler。 High pressure and low pressure bypass system includes steam control valve, desuperheated water control valve, shut off valve and control devices. 鍋爐 主要設(shè)計 參數(shù) Boiler design capacity and parameter 單位 Unit BMCR 工況 BMCR Load TMCR 工況 TMCR Load 過熱蒸汽： Superheated steam 過熱蒸汽流量 Superheated steam flow t/h 2020 Indian NCC 2660MW Supercritical Coalfired Power Plant Page 2 of 27 過熱器出口蒸汽壓力 SH outlet steam pressure 過熱器出口蒸汽溫度 SH outlet steam temperature ℃ 571 571 再熱蒸汽： Reheat steam 再熱蒸汽流量 Reheat steam flow t/h 再熱蒸汽進口壓力 Reheat steam inlet pressure 再熱蒸汽出口壓力 Reheat steam outlet pressure 再熱蒸汽進口溫度 Reheat steam inlet temperature ℃ 再熱蒸汽出口溫度 Reheat steam outlet temperature ℃ 603 603 主給水壓力 Ma
