Improved cookstoves; portable metalliccookstoves; biofuel mix; linear programming model; thermal efficiency; specific fuel consumption
An attempt to study the financial implications of
replacing a traditional biofuel cookstove with an
improved one has been made. The role of several
factors influencing the cost of an improved cookstove has been discussed. The capital cost of a l~opular port- able metallic cookstove design in India has been expressed in functional form and the fuel savings have been quantified in terms of two cookstove performance indicators--overall thermal efficiency of a pot-cook- stove combination and specific fuel consumption of a cookstove. An LP model is proposed for biofuel resource allocation in a rural setting. Expressions for discounted payback period and the net present value of benefits have been derived. Results of some typical numerical calculations indicate that it is financially
quite attractive to replace a traditional cookstove with an improved one. The results of the financial analysis are relatively more sensitive to the economic life of the
cookstove and and price(s) of the biofuel(s).
