【摘要】 通过对上安电厂“W”型锅炉过热器超温的表现及分析,以国内外同类型炉对比及带满负荷的数据说明超温的实质。提出减小卫燃带面积;减少过热器片数;将部分低温过热器改为省煤器。使启动时间缩短,基本消除大屏过热器超温。更多还原

【Abstract】 The essence of superheater over temperature problem of w-flame boiler in Shangan Power Plant was unveiled by phenomena analysis and comparison with similar boilers at home and abroab. Modifications were to reduce the refractory covered area of the furnace, cut off some pieces of platen SH and change a part of primary superheater into economizer, so as to solve the SH over-temperature problem and shorten the starting time.更多还原
