300MW机组滑参数停机的探索

The Exploration to the Sliding-parameter Shutdown of 300MW Unit

采取滑参数停机可以大大的缩短冷却时间,可使高压缸金属温度的平均冷却速度大大提高,使检修时间提前到来,经济效益十分可观;滑参数停机要求也非常高,需要机炉协调一致才能实现。文章探索了相关的操作技术,实现了节能和安全停机的双重效果,可为同类机组的安全运行提供参考和依据。

The cooling time can be shortened greatly, the average cooling speed of the high-pressure cylinders metal temperature can be improved shuttly, and the maintenance time can be advanced with the sliding-parameter shutdown,so the economic benefit is remarkable. The requirements of the sliding-parameter shutdown is very high,and it can be achieved only with the coordination of the boiler and the turbine. The related operation technology is explored,and the double effect of the energy-saving and safety shutdown is realized,and the reference and basis can be provided for the safe operation of similar units.
