It will help to improve living conditions of rural people

DINDIGUL: Gandhigram University should do more research on low cost technologies for rural development. They should find technologies and innovative methods to boost production of jatropha, an alternative energy source to conventional energy, according to M. Vallalar.

Inaugurating the operation and demonstration training on energy efficient wooden log stove held at Gandhigram Rural University here on Tuesday, he said that we need more low cost technologies to improve living condition of rural people. The university could provide low cost technologies to convert urban wastes generated in towns and villages into manure. Such efforts would keep these places clean and recycle degradable wastes in an efficient way, he added. “Higher educational institutions should also develop innovative methods in agriculture production and marketing.”

In his special address, SM. Ramasamy, Vice-Chancellor Gandhigram University, said modern technology had been adopted in this stove to scale down smoke and emission of gases, including carbon monoxide.

Faculty of Rural Oriented Sciences Dean N.S. Nagarajan said the energy efficient wooden log stove, a portable one, was designed based on the feeding rate of firewood with cooking rate by natural draft. This resulted in minimising the smoke and fuel consumption. With no chimney, the stove assured maximum heat recovery. Inclined grate in the stove helped fire wood slide automatically depending on firing rate. Silica-insulated side walls have ensured maximum fuel efficiency. All the heat would go directly to the bottom of the vessel.

Fuel efficiency was 34 per cent compared to 10 per cent in ordinary chulas and 20 per cent in improved chulas.

It has controlled combustion rate and low emission of gases. Presence of carbon monoxide, nitrous oxide and other gases level in ordinary chulas was 300 ppm and it was just seven ppm in this energy efficient stove.

Any type of dry fire wood and agri wastes could be used for burning.

The university distributed 100 stoves, each costs around Rs.3,000, to anganwadi centres in government schools in Athoor block.
