热变温器系统气固反应器内部的温度特性

Temperature profile during gas-solid reaction within reactor for heat transformer

以气固反应热变温器系统的反应器为研究对象,通过建立数学模型,计算了反应器内部在反应过程中的温度分布及其随时间的变化,讨论了一些参数对于反应器内部温度分布的影响。结果表明TC减小、pC增大以及fg减小、ρb增大,使反应器内部温升增加、反应器对废热流体的加热功率q增大,而反应器内部的温度不均匀性亦增加。

Heat transformer with gas-solid reaction could be used to upgrade waste heat. In this paper, the transient temperature profiles within the reactor for heat transformer were studied and some basic characteristics of temperature distribution were analyzed with the variation of parameters, such as Tc, pc, fg and ρb-Through analyzing the temperature distribution profile, it was concluded that with the increase of Pc and ρb, and decrease of Tc and fg, the temperature rise within the reactor and the heating power for waste heat fluid increased, while the temperature distribution became more non-uniform.
