Study on design, development and energy utilization efficiency of smoke reduced hot water stove.

A smoke reduced hot water stove has been designed and developed which provides hot water with normal stove operation. The stove also has the feature of smoke reduced operation to reduce the indoor air pollution. The energy utilization efficiency of smoke reduced hot water stove was compared with conventional stove using common rural fuel. The fuels used were fuelwood (Subabhul), gobar cake, cotton and pigeon pea residue. Out of total energy produced by combustion of fuel wood (Subabhul), gobar cake, cotton and pigeon pea residue, conventional stove utilized 546, 378, 252 and 315 KJ while smoke reduced hot water stove utilized 2348, 1538, 1116 and 1871 KJ respectively. The obtained results revealed that, the smoke reduced hot water stove is 3-5 times efficient in energy utilization than conventional stove. The smoke reduced hot water stove is significant in saving rural fuel, reducing indoor air pollution, improving health of woman and infants and addressing the global issue of deforestation to some extent.
