摘要
Abstract
Considering the daily operation demand for lignite co-firing in a 1000 MW ultra-supercritical bituminous coal-fired unit of a power plant,it carries out co-firing adaptability tests targeting different batches and co-firing ratios of two types of lignite(Baiyinhua and Pingzhuang lignite).Through the comparison of various test conditions,the system analyzes the changes in the operating parameters of the boiler dust removal system,pulverizing system and flue gas and air system,as well as the extent to which the economic efficiency of the unit is affected.The test results show that the high moisture content,high ash content and low calorific value characteristics of lignite can lead to problems such as increased fly ash concentration and reduced output of the pulverizing system,which in turn affect the coordinated operation among various systems and ultimately result in restricted load of the unit.To avoid the risk of equipment abnormality and ensure the safe and stable operation of the unit,the proportion of lignite co-firing in the entire furnace should be controlled within 20%at the current stage,which can provide a reference for the co-firing test of lignite in similar units.关键词
