Biomass innovation aids Mantralayam temple to save energy
The energy-saving innovation of the Mysore-based National Institute of Engineering, Centre for Renewable Energy and Sustainable Technologies (NIE-CREST) has reached the kitchen of Mantralayam temple in Andhra Pradesh.
The Parimala prasadam at the temple is prepared using fuel-efficient biomass stoves "Asthara", designed by the city-based engineering college which save up to 50 per cent of firewood every day.
Five months ago, NIE-CREST replaced the conventional stoves with four fuel efficient biomass stoves. The stoves were installed after studying the entire process of prasadam making. Old conventional stoves were not fuel efficient and they produced more carbon. They had a bad impact on cooks' health. So the NIE-CREST decided to replace them with fuel-efficient stoves, says NIE-CREST director S Shamsundar.
Conventional stoves used to consume more than 500 kg of wood every day but, after installing new stoves it was reduced to 250 kg per day. Fuel efficient stoves have been developed using basic scientific principles of combustion and heat transfer involving conduction. About 70-80 per cent of the heat can be used in this system where it is 10-20 per cent in conventional stoves.
