600MW亚临界燃煤机组启动优化分析

Optimization Analysis of Startup of 600MW Subcritical Coal-fired Unit

为实现亚临界布袋除尘式火电机组在冷态下的快速启动并网,采取了在布袋涂灰和锅炉上水两个方面的启动时间优化,从而保证亚临界机组能及时快速地点火升温升压,缩短启动并网时间,响应电网负荷变化需求。

In order to realize the quick start-up and grid connection of the subcritical bag dust-removing thermal power unit in the cold state,the optimization of the startup time in the two aspects of bag ash and boiler water was introduced.The sub-critical unit could timely and quickly ignite and increase the pressure.The start-up grid time was shorten,and the grid load change requirements was quickly responded to.
