1000MW 超超临界锅炉启动过程中锅炉转态控制要点 刘崇刚 国电泰州发电有限公司，江苏泰州213000 The Points to 1000MW Ultra-supercritical Boiler the Process-control during Beginning LIU Chong-gang Guodian Taizhou Power Generation Co,Ltd,Taizhou Jiangsu 225327 
 摘要：国电泰州电厂一期工程 2×1000MW 超超临界燃煤机组锅炉是哈尔滨锅炉厂有限责任公司由三菱重工业株式会社（Mitsuibishi Heavy Industries Co. Ltd）提供技术支持，设计制造的超超临界变压运行直流锅炉，采用П型布置、双炉膛、一次中间再热、低NOX PM主燃烧器和MACT燃烧技术、反向双切园燃烧方式，底层 1A磨煤机采用等离子助燃技术，炉膛为内螺纹管垂直上升膜式水冷壁，循环泵启动系统；调温方式除煤/水比外，还采用烟气分配挡板、燃烧器摆动、喷水等方式。本文针对国电泰州发电有限公司 2×1000MW 超超临界锅炉启动过程中锅炉转态时出现问题进行分析，提出具体决办法，具有很强的实用性。 关键词：1000MW超超临界锅炉；锅炉启动；中间点；锅炉湿态转干态；水冷壁超温；控制要点 Abstract: Guodian Taizhou Power Generation Co,Ltd, 2 × 1000MW Ultra-supercritical coal-fired unit. The Ultra-supercritical PSA operation boiler made in Harbin Boiler Co. Ltd ,which is provided technical support from Mitsubishi Heavy Industries Ltd. to design and manufacture .It isП-use layout, double-furnace, to heat a middle and low NOX PM MACT main burner and combustion technology, reverse dual-cutting garden combustion, the bottom 1 A mill using plasma combustion technology, within the furnace to screw up the vertical membrane .In addition to the thermostat way coal / water ratio, but also a gas distribution baffle, burner swing, water and other means.This paper, the Taizhou Power Company Limited 2 × 1000MW Ultra-supercritical boiler in the boiler to start the process when the state to analyze problems, propose specific solutions, is highly practical. Key words: 1000MW Ultra-supercritical coal-fired boiler unit, Boilerstart, Mid-point, Boiler wet to dry, Wall Overheating, Control points  1工程概况 国电泰州电厂一期工程 2×1000MW 超超临界燃煤机组锅炉是哈尔滨锅炉厂有限责任公司由三菱重工业株式会社（Mitsuibishi Heavy Industries Co. Ltd）提供技术支持，设计的锅炉是超超临界变压运行直流锅炉，采用 П 型布置、双炉膛、一次中间再热、低NOX PM主燃烧器和MACT燃烧技术、反向双切园燃烧方式，底层 1A 磨煤机采用等离子助燃技术，炉膛为内螺纹管垂直上升膜式水冷壁，循环泵启动系统；调温方式除煤/水比外，还采用烟气分配挡板、燃烧器摆动、喷水等方式。锅炉采用平衡通风、露天布置、固态排渣、全钢构架、全悬吊结构，设计煤种为神华煤，校核煤种分别为兖州煤和同忻煤。
