烟气供暖烟道的研究

Study on Flue Gas Heating

针对烟气供暖,改进烟道形式,利用Fluent软件对不同尺寸的前挡烟板和不同高度的烟道进行非稳态模拟。结果表明:前挡烟板错落高度比4∶2∶1和烟道高度为0.3 m的设计尺寸较优,地面温度均匀,热舒适性强。为新农村烟气地板供暖的设计提供一定参考。

For the flue gas heating,to improve the flue form,Fluent software is used to simulate the non steady state of different sizes of the front baffle and different height of the flue.The results showed that the front baffle ratio of 4:2:1 and the flue height of 0.3 m is the most excellent design,with homogeneous floor surface temperature and good thermal comfort,which can be used as reference for the design of gas floor heating in new rural construction.
