【摘 要】在现代社会的发展中,燃煤锅炉是工业发展中常用的供暖设备、供热设备,尤其在北方地区得到了十分广泛的应用。但是,在使用燃煤锅炉过程中,一定区域内会产生很多燃煤灰尘、SO2气体,现已成为很多地区的大气污染源之一。为了有效控制燃煤锅炉污染物排放量,相关部门需要实行烟气除尘、脱硫方式,做好燃煤锅炉节能改造工作,减少大气污染物的排放量。论文重点分析了燃煤锅炉改造问题及节能环保改造措施。
【Abstract】In the development of modern society, coal-fired boilers are commonly used heating equipment in industrial development, and they have been widely used especially in northern regions. However, in the process of using coal-fired boilers, a lot of coal dust and SO2 gas will be generated in a certain area, which has become one of the air pollution sources in many areas. In order to effectively control the pollutant emissions of coal-fired boilers, relevant departments need to implement flue gas dust removal and desulfurization methods, do a good job in energy saving transformation of coal-fired boilers, and reduce air pollutant emissions. The paper mainly analyzes the problems of coal-fired boiler transformation and the measures for energy saving and environmental protection.

1 引言
我国燃煤锅炉在日常生活供暖、工业生产等领域得到了广泛应用,但燃煤锅炉普遍将煤炭作为燃料,煤炭中的氮元素、硫元素含量比较高,在使用燃煤锅炉时极易出现氮化物、硫化物,这样就会带来严重的能源浪费现象,甚至会带来环境污染问题,相关部门必须做好节能环保改造工作。基于此,论文介绍了燃煤锅炉节能环保原理,分析了燃煤锅炉改造问题,总结了节能环保改造方法及措施。
2 燃煤锅炉节能环保原理分析
工业燃煤锅炉节能和稳定运行与锅炉设计、燃烧控制之间的联系十分密切,锅炉热效率是锅炉设计、运行的关键技术指标之一,相关部门需要注重锅炉热效率的提升,保证锅炉节能环保改造工作的持续性、高效性。在新时期的发展中,锅炉热效率极易受各项因素的影响,如排放热损失、燃料未充分燃烧、热损失等,锅炉热效率会被水、蒸汽、导热油吸收的热量、燃料进行充分燃烧,进而产生热量比值,一般大型燃煤锅炉热效率在60%到80%范围内[1]。……
