For cooking, liquefied petroleum gas (LPG) is one of the most commonly used fuels in India and many other countries. LPG being a clean fuel burns with no soot and has high calorific value than kerosene and wood. In India, as the living standard of the people is improving, the number of LPG consumers is also increasing. The increase is very high in the urban sector. In the year 2004, the dependency of Indian urban domestic sector on LPG fuel was about 48% and for the period of 2010 - 2011, the same had been projected to be about 90%. The total domestic consumption of LPG in India is almost comparable with other petroleum products used in industrial applications. The thermal efficiencies of the current LPG cooking stoves available in the Indian market are in the range of 60 - 65% and at the same time the CO (90 - 1050 mg/m3) and NOX (162 - 216 mg/m3) emissions levels are above the world health organization standards. Moreover, these burners operate in a very low thermal power modulation. Considering the energy conservation, environmental issues and increase in demand on LPG in the near future, there is a need to explore the ways to further improve the thermal efficiency and the emission characteristics of the LPG cooking stoves. In order to overcome the above mentioned disadvantages in the existing cooking burners, this thesis proposes the applicaton of porous medium combustion (PMC) and porous surface combustion (PSC) technologies in domestic cooking stoves. The aim of the present work is to develop the porous burners using PMC and also the combination of PMC and PSC for cooking applications and to analyse the performances in terms of thermal efficiency and emissions levels at different power and equivalence ratios...
