Improvement of Chulha
Johnson has been working as ordinary electrician / mechanic in Tamil nadu Electricity Board. He has designed improved chula (biomass stove) in order to help local villagers to conserve biomass by increasing the efficiency of heating. He has also developed a steel / wooden mould for mass production of chulas. He named this chula Agni-93 as he succeeded in designing during the year 1993 (after unsuccessfully attempting for many years prior to 1993). This is fixed chula type. One can make this chula by using the mould. Raw materials are obtained from locally available red earth. The completed chula can be fixed within one hour. He has so far designed this stove in 35 houses. The women and users are giving good feed back as given below: The size is 12" width x 2" length x11" height. This has to be fixed in kitchen by using 4" width bricks. There is a iron mesh above the kiln which prevent falling of vessels into the kiln. There are provision to hold 2 vessels at closer space. Separate exit for collecting ashes. The smoke is channelised to atmosphere through a long tube like chimney. The cost of chula is Rs.150. It does not need cement. There is no need to plaster the stove with cow dung as performed frequently in conventional model. Maintenance is least and it is comparable to modern gas stove in terms of efficiency and neatness. It consumes less fuel wood and smoke is release outside.
