摘要

随着我国新能源发电装机规模的快速增长，煤电调峰能力不足的问题日益凸显。为了挖掘超临界循环流化床(circulating fluidized bed

CFB)燃煤发电机组的启停调峰能力，以某350 MW超临界CFB机组为研究对象，开展了压火热备与快速启停的试验研究。试验结果表明，超临界CFB机组在压火时能够快速达到近零负荷(平均负荷变化率接近10%Pe/min)，之后维持热备状态达108 min。压火后，锅炉迅速转入湿态运行，主蒸汽压力以0.13 MPa/min的速度快速下降。通过合理控制给水流量，水冷壁和水冷屏工质温度及壁温均保持稳定。残炭燃烧释放热量使压火期间床温下降缓慢，同时为扬火提供了有利条件。在扬火阶段，机组能够迅速启动，NOx排放质量浓度瞬时峰值达101 mg/m3，但小时均值稳定在50 mg/m3以下。在整个试验期间，SO2排放质量浓度始终低于35 mg/m3，污染物满足超低排放要求。汽轮机和发电机在压火热备及启停期间的各项参数均处于正常范围内。主蒸汽压力下降速度过快和主蒸汽温度过热度较低是限制本次试验压火时长的主要因素。研究结果为更高参数的超(超)临界CFB机组启停调峰提供了借鉴。

Abstract

With the rapid expansion of new energy power generation capacity in China

the insufficient load regulation capability of coal-fired power plants has become increasingly evident. In order to explore the start-stop peak regulation capability of supercritical circulating fluidized bed(CFB) power units

a 350 MW supercritical CFB unit was taken as the research object

and experimental studies on banked-fire hot standby and rapid start-stop operations were conducted. The experimental results demonstrated that the supercritical CFB unit can rapidly reduce its load to near zero(with an average load change rate of about 10%Pe/min) during bank firing

and then maintain hot standby for 108 minutes. After banked firing

the boiler quickly switched to wet-state operation

with the main steam pressure decreasing rapidly at a rate of 0.13 MPa/min. By reasonably controlling the feedwater flow

the working fluid temperature and wall temperature of the water-cooled walls and water-cooled panels were kept stable. The heat released from the combustion of residual carbon caused the bed temperature to decrease slowly during banked firing

which also provided favorable conditions for re-ignition. During the load lift phase

the unit could be quickly started

with NOx emission mass concentration reaching an instantaneous peak of 101 mg/m3

while the hourly average was stable below 50 mg/m3. Throughout the entire experimental period

SO2 emission mass concentration was consistently below 35 mg/m3

and pollutant emissions met the ultra-low-emission requirements. All parameters of the steam turbine and generator remained within normal ranges during the hot standby and startup/shutdown. The rapid decline in main steam pressure and the low superheat of the main steam temperature were the main factors limiting the duration of banked firing in this experiment. The relevant research work provides a reference for the start-stop peak regulation of higher-parameter supercritical and ultra-supercritical CFB units.
