摘要

摘要: 焚烧法是处理城市固体垃圾的有效手段，层燃焚烧炉是应用最广泛的城市垃圾焚烧设备。计算流体力学CFD作为一种研究工具，被广泛应用于垃圾焚烧炉的设计优化工作中，最常用的为 FLIC 和 Fluent 耦合的方法，但其无法对燃烧过程全面考虑，并且只能采用人工的方式进行耦合，计算结果误差较大。开发了床层燃烧优化模型，并对比了床层燃烧优化模型及FLIC模型，分析了2种模型的差异，对2种模型的计算结果进行了对比分析。进一步采用床层燃烧优化模型+STAR CCM+自动耦合的计算方法，对某900 t/d的焚烧炉进行了CFD计算。最后采用SHERPA的优化算法，对该焚烧炉配风进行优化计算。优化结果显示其热灼减率从3.1%降低到0.25%，燃料燃烧地更加充分；炉内850 ℃以上烟气停留时间由4.22 s增加到4.55 s，更有利于二噁英的去除。整体来看，模拟计算获得了理想的优化效果，为垃圾焚烧炉的优化设计提供了新方法。

Abstract: Incineration is an effective way for solid waste treatment， with grate incinerators being the most widely used equipment. As a tool， CFD is widely used in the waste incinerator design and optimization， the typical model is coupled by FLIC and FLUENT. However， it cannot fully consider the combustion process and can only be coupled manually， which results in significant errors. This study developed an optimized bed model and compared ot with the FLIC model.In addition， the calculation results from the two models were compared and analyzed. Furthermore， CFD simulations were performed for a 900 t/d incinerator using the optimized bed model coupled with STAR CCM via an automatic coupling method. Finally， the optimization algorithm of SHERPA was used to optimize the air distribution of the incinerator. The optimization results showed that the thermal burn-off rate decreased from 3.1% to 0.25%， and the fuel combustion became more complete； the residence time of flue gas above 850℃ in the furnace increased from 4.22 s to 4.55 s， which was more conducive to the removal of dioxins. Overall， the simulation calculation achieved ideal optimization effects and provide an improved CFD method for waste incinerator design.
