【 摘 要 】

Behaviour of porous media combustion is mainly relay of material used in reaction and preheat zone to possesses high thermal efficiency. Present study deals development of porcelain foam porous media which shall acts as preheat zone to obey peclet number. While in reaction zone consist of alumina foam. In a dual layered micro burner the thickness of reaction and preheat zone was kept at 15 and 10 mm respectively. Burner was developed to achieve not just conventional free flame but also generate submerged flame, varying equivalence ratio (ER). Further, premixed combustion performance was enhanced by running ER below 1, which is lean condition. While optimum ER for surface flame and submerged flame was found to be 0.7 and 0.5 respectively. Maximum thermal efficiency during for surface and submerged flame was turn out to be 90 % and 38 % respectively.
