摘要

为了达到宁夏地区要求现役330 MW级别火电机组NOx排放值100 mg/Nm3以下和改善环境的目的

青铜峡铝业发电有限责任公司对1号锅炉的燃烧器进行技术改造。结果表明:改造后锅炉在330 MW负荷下NOx排放平均值为240 mg/Nm3

比改造前降低45%;锅炉效率达到93.39%(高于设计值0.01%)、飞灰含碳量2.98%(低于设计值0.02%)、过热器减温水量和再热器减温水量均小于设计值;有效解决了锅炉改造前的结焦和超温现象。

Abstract

In order to obtain the aim of Nox emission value below 100 mg/Nm3 for 330 MW level ac?tive service coal-fired unit in Ningxia area and improve the environment

Qingtongxia Aluminium In?dustry Group Power Generation Co.

Ltd. makes the technic improvement for burner of the No.1 boiler.The result shows that after improvement under 330 MW load the Nox average emission value of theboiler is 240 mg/Nm3

reduces 45% than that of before the improvement. The efficiency of the boilerreaches 93.39%(0.01% above the design value)the carbon content in fly ash is 2.98%(0.02% belowthe design value)

desuperheating water quantities of the overheater and reheater are both below thedesign value

and effectively solves the coking and overtemperature phenomena appearing.
