摘要

蓄热室是马蹄焰玻璃窑余热回收、能源循环再利用的重要设备，它对于降低玻璃窑炉整体能耗有着重要的作用。热效率低的蓄热室不但会造成大量的能源浪费，还可能会减少玻璃窑炉的使用寿命，提高蓄热室的热效率已经成为了玻璃产业亟待解决的问题。为了研究蓄热室参数对热效率的影响规律，首先运用计算流体力学理论和多孔介质模型建立了蓄热室的数值仿真模型，然后结合热平衡分析和气体热力学性质变化规律，建立蓄热室热效率模型，最后运用Fluent对不同参数下蓄热室内部温度场与速度场进行仿真，同时从温度场中采集热效率计算数据并分析各参数对蓄热室热效率的影响规律。结果表明：在保证燃料燃烧充分的前提下，减小助燃空气进口速度、格子体孔隙率、格子砖当量直径有利于增大空气与格子体的传热量，提高蓄热室的热效率，而烟道口进口面积在0.9～1 m

时蓄热室的热效率较高。

Abstract

The regenerator is an important equipment for waste heat recovery and energy recycling of the horseshoe flame glass furnace

which

plays an important role in reducing the overall energy consumption of the glass furnace. The regenerator with low thermal efficiency not merely causes an ample amount of energy waste

but also may diminish the lifetime of the glass furnace. Enhancing the thermal efficiency of the regenerator has become a pressing problem to be solved in the glass industry. With the purpose of studying the influence of various parameters of regenerator on thermal efficiency

a numerical simulation model of regenerator is established by using computational fluid dynamics theory and porous media model. Subsequently

combined lance analysis and variation law of gas thermodynamic properties

a thermal efficiency model of the regenerator is established. Finally

Fluent is used to simulate the temperature field and velocity field inside the regenerative chamber with different parameters. Simultaneously

the thermal efficiency data for calculation is collected from the temperature field and the influence of each parameter on the thermal efficiency of the regenerator is analyzed. The results prove that under the premise of ensuring sufficient fuel combustion

reducing the combustion air inlet speed

checkers porosity and refractory brick equivalent diameter are beneficial to augmenting the heat transfer capacity of air and brick

as well as improving the thermal efficiency of the regenerator. Nevertheless

at inlet area of 0.9—1 m

the thermal efficiency of the regenerative chamber is higher.
