| Both commercial and non-commercial fuels are· used in
our country for domestic purposes. Earlier, non-commercial
fuels such as firewood, dung cakes and farm wastes were
predominantly used. Since the availability of these is currently
going dolfn, people are forced to use more and more
commercial fuels such as kerosene, LPG, coal and electricity.
Since the global availability of commercial fuels is
also limited, it is important that these may be used judiciously
and their availability prolonged by increasing the
efficiency of utilization of these fuels. Keeping this in view
more efficient appliances should be designed. The Research
and Development Centre of Indian Oil Corporation has
developed an improved kerosene stove which bas over 60%
thermal efficiency as compared to 35 to 47% efficiency of
the marketed stoves. Tbi!l is likely to save 30% kerosene
on an average. |
