摘要
对国产 2 0 0 MW燃煤机组参与电网调峰的可行性进行了研究。通过对柳州电厂 1、 2号机组进行变压降负荷试验 ,结果表明 :柳州电厂 2 0 0 MW机组可在 1 2 0 MW负荷下安全运行 ,锅炉燃烧稳定 ,汽水品质合格 ,汽机各主要参数基本在限额范围内。通过分析指出 ,为了提高机组低负荷运行的效率 ,提高负荷变化率 ,火电机组应尽量采用变压降负荷运行方式。
The feasibility of 200 MW domestic coal fired units of Liuzhou Thermal Power Plant participating the peaking operation of power networks is studied Through variable pressure load down tests on units No 1 and 2 of Liuzhou Thermal Power Plant, it turns out that the 200 MW units can operate safely and the boiler combustion keeps stable along with qualified steam quality and the main parameters of steam turbines basically within limits under the conditions of 120 MW load The result of analysis indicates that variable pressure load down operation mode should be adopted by the thermal power generating units as to raise the efficiency of units' low load operation and the rate of load change
