摘要
在能源与环保压力下,工业锅炉的热效率备受关注。以20 t·h^(-1)工业蒸汽锅炉螺旋形烟管为研究对象,针对现有结构存在的热效率瓶颈,提出变螺旋升角、变管径梯度及增加内壁扰流结构的优化方案。数值模拟与试验验证结果表明:优化后烟管系统阻力损失降低23.5%,换热系数提高18.2%,锅炉热效率从88.3%提高至91.7%。研究有效突破了传统烟管结构的热效率瓶颈,为工业锅炉节能降耗提供了创新技术路径,对推动工业领域节能减排具有重要意义。
Under the pressure of energy and environmental protection,the thermal efficiency of industrial boilers has drawn much attention.Taking the spiral smoke tube of the 20 t·h^(-1)industrial steam boiler as the research object,aiming at the thermal efficiency bottleneck existing in the current structure,an optimization scheme of changing the spiral Angle,changing the tube diameter gradient and adding the inner wall turbulence structure is proposed.The results of numerical simulation and experimental verification show that after optimization,the resistance loss of the flue pipe system is reduced by 23.5%,the heat transfer coefficient is increased by 18.2%,and the boiler thermal efficiency is raised from 88.3%to 91.7%.The research has effectively broken through the thermal efficiency bottleneck of the traditional smoke tube structure,providing an innovative technical path for energy conservation and consumption reduction in industrial boilers,which is of great significance for promoting energy conservation and emission reduction in the industrial field.
