360MW机组冷态启动节油探讨

A Study on the Fuel-efficient Cold Start of the 360MW Unit

介绍了360 MW燃煤机组在冷态启动时节约燃油方面所采取的一系列技术措施和组织措施,重点分析了燃油充分燃烧、提前投粉以粉代油、强制循环汽包炉的沸点水位控制、启动初期温度控制,使启动曲线尽量接近厂家的标准启动曲线。总结其中的经验,找出机组冷态启动过程中的节油空间,挖掘机组启动的节油潜力,优化机组的启动方式,为同类型火力发电厂的机组冷态启动节油提供参考。

This article introduces the technical and organizational measures in the fuel-efficient cold start of the360 MW coal-fired unit. In addition,it analyzes such measures as the sufficient burning of the fuel oil,the oil replacement with pulverized coal by putting in it in advance,the water level control of the boiling point of the forcedcirculation drum-boiler and the temperature control of the initial stage of the start,which can make the start curve closer to the standard start curve of the manufacturer. By summing up relevant experience,discovering the fuel-efficient space during the process of the cold start of the unit,exploiting its fuel-efficient potential and optimizing its start mode,this article can provide reference for similar thermal power plants in this field.
