Abstract

A study was conducted to assess the heating performance and pollutant emissions from burning of biocoal (briquetted char) prepared from waste tender coconut. Heating performance with respect to calorific value, cooking efficiency and burning rate of biocoal, possessing coal like properties has been investigated. A solar powered forced draft cook stove was used to evaluate the heating performance and emissions of gases such as CO2, CO and HC while burning the biocoal in it. The biocoal was prepared from waste tender coconut through the process of carbonization and then densification of char with the use of five different binding materials such as cow dung, kitchen wastes, food waste, grass and waste paper slurry because of their easy and cheap availability. The loose char obtained from the carbonization process was densified by hand press method. From the study, it was revealed that the calorific value of the charred tender coconut waste is about 38% higher that of the uncharred raw ten
