摘要
随着我国国民经济的高速发展和人民生活水平的提高,在各大电网容量不断扩大的同时,用电结构也在不断变化,市政用电比重逐年上升,工业用电比重相对下降,各大电网峰谷差日趋增大,机组不可避免地低负荷运行。潮州发电厂2台1 000 MW机组也要参与深度调峰,因此有必要在保证锅炉经济性和安全性的前提下,针对潮州电厂百万机组特征总结运行经验,保证机组的经济与安全运行。
With the rapid development of our national economy and the improvement of people＇s living standard,while the large power grid capacity continues to expand, power consumption structure is changing, municipal electricity pro- portion rises year by year, the proportion of the industrial electricity declines, the peak valley difference increases with each passing day,the unit will be inevitably at low load operation. Chaozhou power plant＇ s 2 sets of 1 000 MW units must be involved in the depth of peak shaving, so it is necessary to ensure the safety and economy of boiler, summarize the operation experience in view of feature of 1 000 MW units in Chaozhou Power Plant to ensure the se- curity and economic operation of the unit.
