【Abstract】 The combustion mechanism of premixed combustion in porous medium is discussed both with its strong virtues and broad application. Researches and investigations on thermo physical and transportation characteristics of porous medium materials are reviewed. From such as radiation sendout, stability of combustion, combustion velocity and waste emission, researches on premixed combustion of gas fuels in porous medium burner are discussed in detail. It also reviews the investigations on non-homogeneous porous medium burner and staged combustion burner, and present an idea of designing a Gradually-varied Porous Media burner, which is more matched with combustion discipline.更多还原
