基于实验研究的浸没式燃烧器结构优化

Structural Optimization of Immersion Burner for Experimental Research

浸没燃烧设备作为一种直接接触液体表面进行传热的新型加热设备,其结构优化尤为重要。实验对浸没装置结构进行了优化,以提高稳压效果和蒸发效率。首先通过冷态实验在一定工况条件下对直管、多孔片、圆形挡板环和带圆形挡板环的多孔片四种浸没管结构进行压力波动特性研究。其次通过热态实验在浸没深度150 mm、流量为6 m^(3)·h^(-1)、孔径为10 mm的工况条件下对多孔片型、圆形挡板环型,以及带圆形挡板环的多孔片型四种浸没管结构进行升温研究。结果表明,带圆形挡板环的多孔片型结构是提高稳压效果与蒸发效率的最佳结构。

For immersion combustion equipment,as a new type of heating facility that directly contacts the liquid surface for heat transfer,structural optimization is particularly important.This article presents optimization of the structure of immersion device to improve the stabilizing effect and evaporation efficiency.Firstly,the pressure fluctuation characteristics of four submerged tube structures,namely straight tube,porous plate,circular baffle ring,and porous plate with circular baffle ring,were studied through cold state experiments under certain operating conditions.Secondly,the four types of immersion tube structures were studied for temperature rise through hot state experiments under operating conditions,with immersion depth of 150 mm,flow rate of 6 m^(3)·h^(-1) and pore size of 10 mm.It is indicated that the porous plate structure with a circular baffle ring is the most promising structure to improve the voltage stabilization effect and evaporation efficiency.
