Abstract: Performance evaluation has been carried out of BIS high-pressure kerosene stove incorporating porous medium technology (PMT) in conventional burners. Burners with and without porous material were used for the study in terms of thermal efficiency, kerosene consumption rate and emission. Overall fuel saving was found to be 103 g/h (34%) with increase (10-11%) in thermal efficiency. Similarly, emission factors for pollutants CO (% vol), HC (ppm) and NOx (ppm) were controlled in the range of 32%, 15% and 83% respectively with PMT. Flames stabilized within the port of porous structure due to internal heat feedback of burned gases to unburned gases by radiation and conduction. Such flames produce higher burning velocity and leaner flammability condition and contributes to low NOx formation. Thus, PMT may be useful in terms of fuel economy and environmental compatibility.
