A new trend of utilizing the porous burner technology for the application of domestic cooking was observed because of its high efficiency and low emissions. This research work presents the experimental analysis of three types of porous burners having uniform diameter of 90 mm, 70 mm and divergent shape burner having the top diameter of 90 mm and bottom side diameter of 70 mm respectively. The fuel used for all the experimental trials was, Liquified Petroleum Gas (LPG). Porous burners consist of two zones i.e. preheating zone and combustion zone. The test piece preheating zone was filled with steel balls of diameter 6.5 mm and in combustion zone porous matrix of SiC foam of 10 ppi was used. Height of combustion zone was kept constant for all the three burners at 25 mm. Burner was operated at different equivalence ratio ranging from 0.10-0.60. The maximum efficiency of 79 % was observed for porous burner of diameter 90 mm at equivalence ratio (Φ) of 0.49 and 0.84 kW power.

High efficiency and low efficiency were observed by using porous burner technology for commercial cooking. The whole research consists of survey of these three types of burners. Like burners diameter having convergent 100mm, straight 100mm and80mm divergent shape burner. LPG is the fuel i.e. liquid petroleum gas is used in the all experiment. The two zones combustion and preheating zones comprise by a porous burner. Preheating zone having steel balls of width 6.5mm where combustion zone has Sic matric of 10ppi was used. 150mm is the constant altitude of three burners comprise of combustion zone and having equivalence ratio from 0.10-0.60. The range at which burner was operated 79% is the maximum efficiency analyzed for porous burner having dimensions like 100mm diameter at power equal to 0.84 kW and equivalence ratio (Φ) equal to 0.49.
