Abstract
In India and other Asian countries, Liquefied Petroleum Gas (LPG) has been used extensively used as a fuel for domestic cooking as well as large ?scale cooking applications. Being the 4th largest LPG consumer, India has been spending huge amount of money for subsidizing the domestic LPG cylinder (14.5 kg) price from $16 to $7. Considering the depletion of fossil fuel resources, environmental issues, and financial burden on the Government of India for subsidizing the domestic LPG price, there is an urgent need to explore the ways for improving the performances of the existing LPG cooking stoves. Tests carried at IIT Guwahati shows that the conventional LPG burners available in the market are having 55-65% thermal e ffi ciency, and high CO and NOx emissions.This presentation briefs about the development of the PRBs used for LPG cooking applications. Performances tests on the PRB have been carried out employing different porous materials, porosities, geometric dimensions, etc. At the operating condition of 0.54 equivalence ratio at 1.3 kW power intensity, the reported maximum thermal e ffi ciency of the 90% porosity SiC based PRB was about 75%. Thermal e ffi ciencies of all the tested burners gradually decrease with increase in the equivalence ratios and power intensities. Optimum porosity of the 90 mm burner was found to be 90%. PRB showed the stable combustion in the equivalence range of 0.52 - 0.65. Emission indices of all PRBs are lower than that of the conventional LPG domestic cooking stoves available in the Indian markets. The radial temperature distribution of the combustion zone was found to be uniform. For large ?scale cooking application having the power range of 5 - 10 kW, the measured thermal e ffi ciencies are in the range of 50-55%, which is about 25% higher than the conventional stoves.
