摘　　要：循环流化床锅炉、煤粉工业锅炉因能效高、环保性能好,是燃煤工业锅炉的重要发展方向,为满足锅炉选型需要,从技术性能、运行维护、经济、环保等方面对两种炉型对比分析,并结合项目案例进行实践比选。项目案例表明:因所在地周边无集中制粉厂家,该案例煤粉工业锅炉需要炉前制粉,煤粉工业锅炉方案建设投资比循环流化床锅炉方案高626万元,蒸汽生产成本比循环流化床锅炉方案低33.6万元/a;由于煤粉工业锅炉附属制粉工艺安全隐患较多,因此,从经济性和安全性考虑,项目案例选用循环流化床锅炉方案。两种炉型没有绝对的优劣,循环流化床锅炉适应煤质范围宽,煤粉工业锅炉更适应周边环境要求高、自动化水平高的区域,要根据具体场景、条件,选择最适宜的炉型。Circulating fluidized bed boilers and coal powder industrial boilers are important development directions for coal-fired industrial boilers due to their high energy efficiency and good environmental performance.In order to meet the needs of boiler selection,a comparative analysis of the two types of boilers is conducted from the aspects of technical performance,operation and maintenance,economy,and environmental protection,and practical comparison is carried out based on project cases.The project case shows that due to the lack of centralized powder manufacturers in the surrounding area,the coal powder industrial boiler in this case requires pre furnace powder production.The construction investment and steam production cost of the coal powder industrial boiler scheme are 6.26 million yuan higher and 336000 yuan/year lower than those of the circulating fluidized bed boiler scheme,respectively.There are many safety hazards in the auxiliary powder production process of the coal powder industrial boiler.Based on economic and safety considerations,the circulating fluidized bed boiler scheme is selected for the project case.There is no absolute superiority or inferiority between the two types of furnaces.Circulating fluidized bed boilers are suitable for a wide range of coal quality,while coal powder industrial boilers are suitable for areas with high environmental requirements and automation levels.The most suitable furnace type should be selected based on specific scenarios and conditions.
