Development of porous radiant burner for LPG domestic and commercial cooking stoves |
6 Ph.D 12 M.Tech 4 Project Staff Publications:20 Patents : 3 (PCRA and IMPRINT projects) |
Designed and developed LPG cook stoves with porous radiant burners (PRB) for domestic and commercial cooking applications. The reported fuel saving of the newly developed PRBs are 17% and 45% for domestic and commercial cooking applications, respectively. Measured CO and NOx emissions of the LPG stoves with PRBs are much less (one fourth) in comparison with conventional cooking stoves.
Payback period of these burners are less than 4 months for domestic and 1 month for commercial applications. Commercialization of these burners are under process in coordination with an industrial partner through MHRD sponsored under IMPRINT Project scheme. |
Development of porous radiant burner for domestic kerosene cooking stove. |
1 Ph.D 3 M.Tech 1 Project Staff Publications:8 Patents : 2 (PCRA and IMPRINT projects) |
Designed and developed energy efficient PRBs for domestic kerosene cooking applications and reported 10% and 15% fuel savings with normal kerosene and 0.2 wt % TiO2 blended kerosene, respectively. |
Development of porous radiant burner for bio-gas operated domestic cooking stove. |
1 PhD 2 M.Tech 1 Project Staff 1 national patent is filled. Publications: 5 |
Developed working prototypes of porous radiant burners (PRB) fueled with bio-gas for domestic cooking stoves. Achieved 15 % improved in thermal efficiency compared to conventional bio-gas operated stoves. Commercialization of the above-mentioned product is under process. |
