摘　　要：为了准确掌握燃煤锅炉在低负荷稳燃等恶劣工况下的壁温分布,采用Ebsilon16.4软件模拟分析了冷灰斗水冷壁、螺旋管水冷壁和垂直管水冷壁的压力、温度及质量流量对水冷壁的换热量、金属壁温及平均热流密度的影响。结果表明:冷灰斗水冷壁与垂直管水冷壁的传热特性曲线变化趋势较为相似,而螺旋管水冷壁处的换热量及平均热流密度曲线的变化趋势与前两者完全相反,验证了螺旋管的抗热偏差能力较强。In order to accurately grasp the wall temperature distribution of coal-fired boiler under severe conditions such as stable combustion at low load,the influence of pressure,temperature and mass flow on heat transfer,metal wall temperature and average heat flux density of water walls of cold ash hopper,spiral tube and vertical tube was simulated and analyzed by using Ebsilon16.4 software.The results show that the variation trends of the heat transfer characteristic curves of the water walls of the cold ash hopper and the vertical tube are similar,while the variation trends of the heat exchange quantity and average heat flux density curves of the spiral tube water wall are completely opposite to the former two,which verifies that the spiral tube has strong heat resistance deviation ability.
