Progress in the Research on Diffusion Filtration Combustion in Porous Medium

Abstract

Diffusion filtration combustion attains widely attention as its small volume, compact structure, large power range and less emissions which is very important for saving energy in recent years. It is the combustion that fuel and oxidant are separated before burning in porous media. The researches about diffusion filtration combustion are summarized the theory, experiment and numerical simulation in this paper. There is still much knowledge unknown which should be worked on.

Investigation of the Combustion Properties of Ethylene in Porous Materials Using Numerical Simulations

“…The design of the porous medium burner requires an analysis of the propagation and stability of the combustion wave in the reactor. Therefore, this study aimed to design a physical model of the burner and focused on aspects such as the distribution and variation of combustion temperature [10], the speed of flame propagation, and the conditions for stable flame combustion [11]. The benefits of the enhanced porous medium burner in terms of heat value and pollutant emission were investigated and may be attributed to the properties of porous medium with excellent heat storage, radiation heat conductivity, and a stable flat flame formed on its surface in a certain equivalence ratio and flow range.…”
