【摘要】 电厂来煤复杂多变、燃煤品质严重偏离设计值,导致锅炉飞灰可燃物质量分数居高不下。采取规范燃煤掺配管理、根据不同煤种调整HT-NR3型旋流煤粉燃烧器配风和限制无烟煤一次风速等措施后,在入炉煤保持1/3无烟煤、2/3烟煤的情况下,锅炉飞灰可燃物质量分数可控制在3%左右。更多还原

【Abstract】 The incoming coal of a power plant is complex and variable,and the quality of the incoming coal is far deviated from the designed value,which causes the mass fraction of combustibles in fly ash of the boiler to staying at a high level.Some measures were adopted,which includes to normalize the coal blending management,to adjust the air distribution of the HT-NR3 swirl pulverized coal burner according to different coal type and to control the first air speed for blind coal,and when a third of incoming coal is blind coal and two-thirds are bituminous coal,the mass fraction of combustibles in fly ash of the boiler can be controlled at about three percents.更多还原
