The comparative efficiency between conventional traditional stove and modern modified rocket stove in ladakh- analysis of time saving, energy saving and temperature variation on different chamber

Ladakh a cold arid desert lie in the lap of trans Himalaya where temperature drop down more the minus 30°c in pick winter and in summer temperature scale up more than plus 30°c. such area is mainly accompany with cold climate where heat stove is the major essential commodity for inhabitant. Since existence of livelihood stove is the closed and major essential commodities of area. Cow dung and locally produce woods are the major source of fuel, with the passage of time and technology new modified and fuel efficient stoveswere developed one of which is Himalayan rocket stove which become highly popular and effective from last two to three year. This study examined comparative time saving, energy saving efficiency, purpose serve and heat lasting between traditional and modern modified rocket stove. The analyzed result reviled that in term of time saving traditional stove is better than modern stove (time taken by modern rocket stove to boil 2 lit of milk = 25 minute whereas traditional stove took 15 minute), Energy saving / fuel consumption is concern modern rocket stove is better than traditional stove (1050 gm of cow dung and 150 gm of wood consume to boil 2 lit of milk whereas rocket stove consume hardly 700gm of cow dung and 100 gm wood. In the case of heat lasting modern modified rocket stove is far batter then traditional stove may be better utilization of material, but multi-purpose serve is concern traditional stove serve much purpose then rocket stove. The study finding both the stove have their own limitation and advantage but can be improved by doing few modifications for better utilization.
