Societal benefit and impact anticipated

Penetration of these stoves into cooking applications can save about 2 kg of LPG per 14.2 kg domestic cylinder and 6 kg per commercial cylinder and thus both the consumer and the government can save huge amount of money. Considering the present domestic consumption of 30 lakhs cylinder per day, with the above mentioned LPG saving, the amount money saved for the government is approximately Rs. 8000 crore per year. Further, if the industrial consumption is also taken into account, the projected total LPG saving per annum will be very huge. Commercialization of these technologies will also open up huge employment in the rural areas.

Next steps

1. Based on the results from Control Cooking Test (CCT), Kitchen Performance Test (KPT). and Techno-economic Assessment (TEA), final improvement in the design of self-aspirated LPG operated PRB Cook-stove for domestic and commercial application will be done. 2. With final design, fabrication of 125 Nos (50 LPG stoves of domestic application, 50 LPG stoves of commercial application, and 25 kerosene stoves) cook stoves will be planned in coordination with Industry partner and LERC as per BIS standard. 3. Design and fabrication of 10 numbers of self-aspirated LPG operated PRB Cook-stove for commercial application in the power range of 7-10 kW will be done. 4. Design and fabrication of 10 prototypes of self-aspirated LPG operated PRB Cook-stove with cluster PRB along with performance assessment will be done. 5. Finalize the design of self-aspirated biogas operated PRB Cook-stove for domestic and commercial application and fabricate 5 prototypes of each for further testing. 6. Development of thermal model for optimization of PRB geometry and various dimensions of the PRB, porous matrix, etc. 7. Life cycle performance assessment of above developed PRB cook stoves.
