EXPERIMENTAL INVESTIGATION ON EFFECT OF SKIRT ARRANGEMENT ON MODIFIED BOILING POT

A lot of research work has been done in the literatures emphasizing on technical aspects of modified cook stoves; primarily on the performance and minimization of harmful emissions. But in published literatures limited investigation was made for improving boiling efficiency by using modified pot surfaces and use of skirts in boiling pots. In order to improve boiling efficiency, pot with modifications has greater impact to maintain balance between the technical capabilities and usability. This modification includes a low cost pot skirt that integrates directly with the standard flat bottomed pot. The effect of gap variation along the skirt on boiling efficiency at different heat input is investigated. Also the effect of aluminium foil on the skirt surface is investigated. Most of the researchers work on biomass stove for improving boiling efficiency, but there is limited work on Liquefied Petroleum Gas (LPG). Conducting the Water Boiling Test (WBT), it is identified that pot skirts improve boiling efficiency by 8-10% in all set of experiments and is observed maximum for a skirt gap of 8mm. The efficiency is further improved by using aluminium foil at the inner surface of the skirt. There is much less technical improvement on inexpensive energy efficient cookware. However these pot skirts could potentially improve boiling efficiency of cookware.
