SWOSTHEE Single Pan Wood Stove
Dear Stovers:
I hope you saw this article in the recent issue of BUN-INDIA copied to the
bioenergy list. It can be found at http://144.16.73.100/~mukunda/home.html
Has anyone used one? How does the performance compare to other stoves?

SWOSTHEE
Single Pan Wood Stove Of High efficiency A Fuel Efficient
Portable Cookstove,
Svathi Bhogle
Swosthee is a portable metallic single pan stove designed at
the Indian Institute of Science, Bangalore. It has a heat
utilisation efficiency of 32 % which is the highest among
all single pan stoves in India today. Even by a conservative
estimate, usage of high efficiency stoves like Swosthee can
conserve 84 million tonnes of firewood annually in India
alone. Some other salient features of the stove are:
o It is a multifuel stove capable of burning a variety of biomass like
firewood,coconut shells, cowdung cakes, twigs and briquetted
agricultural residue.
o Reduced emissions (CO - less than 20 PPM at the operator level and
Suspended Particulate Matter in the range of 1.0- 1.5 mg/m3). A power
input of 3.5 kW.
o Easy ignition and maintenance.
o Versatility -The stove can be used with vessels of all sizes
and shapes and is suitable for cooking all types of common
dishes.
The Swosthee stove is designed by a team of scient-
ific workers who do not use firewood burning stove as a part
of their daily routine. Their objective was to design astove
with a maximum heat utilisation efficiency, minimum release
of hazardous emissions and as user friendly as could be per-
ceived by them. A survey was therefore carried out among
rural, semi-rural and urban households to obtain first hand
information on stove usage, cooking practices and user
response to Swosthee stoves.A near unanimous conclusion from
the survey was that the Swosthee stove saves fuel and time
and also emits significantly less smoke than traditional
stoves. All types of users found the stove to be sturdy,
stable and easy to ignite and maintain. Other inferences that
can be drawn from the survey are:
The Swosthee stove is ideal for a family size of 5-6
members.
The Swosthee stove is especially suited for houses having
roofs made of reinforced concrete,asbestos or other sheets
and thatch.
The Swosthee stove has a high acceptability among househo-
lds living in urban slums where the size of the house is
small.
The survey also categorically confirmed that the two most
important attributes that a potential user is looking for in
a cooking device is a reduction in the cooking time and a
saving in the fuel bill. Swosthee stoves will meet the cook-
ing requirements of a variety of users not only in India but
elsewherein the world as well besides reducing deforestation
and emission of hazardous emissions.
