IIT Guwahati transfers energy-efficient cookstove technology to industry partner

The porous radiant burner (PRB) provides fuel saving in the range of 25 per cent to 50 per cent and can be operated with LPG, biogas and kerosene. 

The Indian Institute of Technology (IIT) Guwahati has transferred an energy-efficient and environment-friendly technology developed for cookstoves by its researchers to an industry partner for commercialisation.  

A research team headed by P Muthukumar, Department of Mechanical Engineering, IIT Guwahati, has developed porous radiant burners (PRB) for cookstoves equipped, which can provide the fuel saving in the range of 25 to 50 per cent. It can be operated with LPG, biogas and kerosene. The technology has been transferred to an industrial partner Agnisumukh Energy Solutions Private Ltd, Bangalore, for commercialisation.

Burners can reduce carbon monoxide, nitrogen oxide emissions 

Muthukumar said, “These indigenously developed cookstoves equipped with specially designed double layered PRBs provide fuel saving in the range of 25-50 per cent and reduces carbon monoxide (CO) and nitrogen oxide (Nox) emissions by about 80 per cent.”  

The IIT Guwahati research team believes that the commercialisation of PRB-based LPG cookstoves across India will provide a huge LPG saving of about 13 lakh domestic cylinders per day and also will have a global impact on the burner-based applications. 

Technology can save INR 50K crore annually: Director 

TG Sitharam, Director, IIT Guwahati, said PRB-based cookstove technology will play a key role in reducing the overall fuel consumption in the cooking sector, leading to a huge annual saving of about INR 50,000 crore for the government, thus reducing the financial burden significantly and conserving energy. Further, it will also provide a better cooking environment by reducing CO and NOx emissions.
