燃用土耳其高水分低热值褐煤锅炉选型及设计控制措施

Selection and Design Control Measures of Turkish High-Moisture Low-Calorific Value Lignite Boiler

土耳其褐煤是一种高水份、低热值、高挥发份、易燃烬、易结焦特性的燃料,传统的褐煤发电锅炉多采用煤粉锅炉,存在制粉系统选型困难,低负荷稳燃特性差,炉膛结焦倾向严重,制约了褐煤开发利用。文章主要论述了燃用土耳其高水分低热值褐煤锅炉选型及设计控制措施,供同类型褐煤锅炉选型及设计参考使用。

Turkish lignite is a fuel with high moisture,low calorific value,high volatile content,flammable embers,and easy coking characteristics.Traditional lignite power generation boilers mostly use pulverized coal boilers,which are difficult to select for the pulverizing system,and low load is stable.Poor combustion characteristics and serious coking tendency in the furnace have restricted the development and utilization of lignite.This article mainly discusses the selection and design control measures of Turkish high-moisture low-calorific value lignite boilers,which are used as references for the selection and design of the same type of lignite boilers.
