摘　　要：由于锅炉炉膛长期处于高温、高压和腐蚀性气体环境,容易导致高温腐蚀、热疲劳、氧化皮剥落和机械磨损,这些损伤会降低设备寿命、增加维护成本,并影响锅炉的运行效率和安全性,因此其结构设计和材料选择必须耐热、耐高压和耐腐蚀。炉膛的设计和操作直接影响燃烧效率和锅炉整体效率,深入了解燃烧和高温腐蚀对炉膛的影响,有助于优化锅炉设计,提高燃烧效率,延长设备寿命,减少维护成本,并有效降低污染物排放,提升能源利用率和环境友好性。Due to the long-term exposure of boiler furnace to high temperature,high pressure,and corrosive gas environments,it is easy to cause high-temperature corrosion,thermal fatigue,oxide skin peeling,and mechanical wear.These damages will reduce equipment life,increase maintenance costs,and affect the operational efficiency and safety of the boiler.Therefore,its structural design and material selection must be heat-resistant,high-pressure resistant,and corrosion-resistant.The design and operation of the furnace directly affect the combustion efficiency and overall boiler efficiency.A deep understanding of the impact of combustion and high-temperature corrosion on the furnace can help optimize boiler design,improve combustion efficiency,extend equipment life,reduce maintenance costs,and effectively reduce pollutant emissions,improve energy utilization and environmental friendliness.
