A technical evaluation of woodstoves in rural Pakistan

Technical Report:

Abstract

A technical evaluation of wood stoves has been carried out in rural Pakistan. A water boiling test (WBT) was used to study how variations in stove design affect fuel efficiency. Controlled cooking test (CCT) were designed to study cooking performance in the preparation of standardized meals. Field performance tests were expected to indicate the overall change in fuel consumption, and other impacts in the daily use of new design of stove. Two improved stove designs, the ATDO and the GTZ, were compared with a traditional stove (TS). The WBT`s revealed a poor fuel performance for the ATDO stove which was excluded from further comparative testing. The GTZ stove performed systematically and significantly better than the TS and ATDO stoves in WBTs, showing a saving of almost 50% fuel over the TS. In the CCTs both the GTZ and TS showed widely differing sets of efficiencies for different cooking requirements, ranging from 3% to 14% for the TS and from 4% to 27% for the GTZ. Elementary estimates, assuming two hypothetical households, indicated fuel savings in the range 20% to 44% using the GTZ stove. In the FPTs, however, fuel savings of only 20% were realized by the GTZ. This unexpectedly  More>>

Elementary estimates, assuming two hypothetical households, indicated fuel savings in the range 20% to 44% using the GTZ stove. In the FPTs, however, fuel savings of only 20% were realized by the GTZ. This unexpectedly low value is in part due to the inability of the stove to maintain low simmering power and also, possibly, due to the wrong sized pan being used by the operators. One significant limitation of the GTZ stove is that it does not perform all operations equally well and should be redesigned, in particular, for more efficient bread-cooking. (UK).}
