摘要： 对陕西能源赵石畔煤电有限公司的一台1 000 MW 超超临界机组锅炉进行了性能试验研究， 分析了燃用高硫煤
时锅炉在高、低负荷运行下， 对锅炉效率、锅炉最大连续出力、空气预热器漏风率、汽水系统压降、空气预热器进出口
烟风压降、NO_x排放的质量浓度的影响。结果表明：在100%额定负荷、75%额定负荷和50%额定负荷下，锅炉效率均达
到95%以上，高于保证值94.9%；锅炉最大连续出力为2 915 t/h，高于保证值2 906 t/h。在锅炉最大连续出力工况下，A
侧、B侧空气预热器漏风率均低于4.00%，达到保证值；过热器蒸汽侧、再热器蒸汽侧的压降均低于保证值；但A 侧、B
侧空气预热器二次风压降偏差均大于10%，没有达到设计要求。在100%额定负荷下， 锅炉NO_x排放的质量浓度（脱硝
前） 平均值为1 59 mg/m³（O₂体积分数=6%，标准状态），低于保证值，达到设计要求。测试所得结果为1 000 MW超超
临界机组的安全、经济运行提供了参考，性能测试方法值得推广和借鉴。

Abstract: This paper carried out the performance tests on an ultra-supercritical 1 000 MW unit boiler in Shaanxi Energy Zhaoshipan
Coal & Electricity Co., Ltd. The effects of the high-sulfur coal fired on boiler efficiency, boiler maximum continuous rating
(BMCR), air leakage rate of air preheater, pressure drop of steam water system, pressure drop from inlet to outlet in air preheater
and NO_xemission concentration were investigated in this work. Results showed that boiler efficiency reached more than 95% in
100%, 75% and 50% rated load which were more than its design guarantee value of 94.9%; BMCR was 2 915 t/h which was more
than its guarantee value of 2 906 t/h. Under the BMCR test condition, the air leakage rates from Side A and Side B of air preheater
were both lower than 4.00% and reached their guarantee values; the values of the pressure drop from steam side of superheater
and steam side of reheater were both lower than their guarantee values; while the pressure drop deviation values of secondary air
from Side A and Side B of air preheater both were more than 10% and didn't meet the design requirements. The average value of
the NO_xemission concentration in 100% rated load was 159 mg/m³(volume fraction of O₂=6%, standard conditions) and was lower
than its guarantee value, meeting the design requirement. The results obtained offer useful reference for the safe and economical
operation of the ultra-supercritical 1 000 MW unit boiler. This performance test method is worth applying and recommending.
