IIT-G comes up with fuel-friendly cooking stoves NewsFunda

GUWAHATI: The researchers at IIT Guwahati have come up with a cooking solution that can cut down on fuel consumption by almost 40% and emission of harmful gases thereby creating cleaner homes and environment. The innovative cooking stoves can run on any fuel whether it is kerosene, LPG or biogas and are fitted with especially designed porous radiant (PRB) burners.

The USP of the innovation is the use of advanced combustion technology, which has made the cooking stoves energy-efficient, economical and eco-friendly. The research team believes the work will have a global impact on burner-based applications and their multi-billion-dollar market. They plan to commercialize the technology in a year’s time and corroborate with industrial partners to extend the reach of these stoves in the Indian market.

“For domestic cooking applications, we can save about 30% fuel. For commercial applications, 40-43% fuel can be saved,” P Muthukumar, who developed the technology with his research team, told TOI on Tuesday.

Minimizing emission, which has been a prime concern in conventional burners, he said this innovation is a milestone. “Highly harmful carbon monoxide emission can be reduced to one third as compared to convention burners, whereas nitric oxide emission is almost zero,” he added.

“The findings of these developments have been patented and the PRBs can be effectively used for domestic as well as community and commercial cooking. The prototypes needed for the invention have been developed in-house and are rigorously tested against available BIS standards,” Muthukumar said.


He went on to stress that having access to reliable, clean and modern cooking energy improves the standard of living. “The provision of clean cooking energy also addresses concerns related to food security, climate change and health care,” he added.


A recently published article in the Lancet Planetary Health Journal reported that household pollution led to 0.65 M deaths which amount to 6.5% of the total deaths in India. Similarly, household air pollution is also responsible for 4.5% of the total disease burden (measured as disability-adjusted life-years (DALYs)). These deaths and morbidity eventually add up to huge monetary losses that further add to the economic burden of the country. Household air pollution is caused mainly by the use of polluting cooking fuels and inefficient cooking stoves.
