Cocopeat pellet gas stove

Abstract

Cocopeat, which is one of the difficult- to-dispose biomass wastes, can be used as fuel for domestic cooking. With the annual production of about 14 billion nuts of coconut in the country, an estimated amount of 2.8 million metric tons of cocopeat is produced. Pelletizing cocopeat and gasifying it in a Top-Lit Up-Draft (TLUD) type gasifier stove, this waste can now be used as fuel for domestic cooking. This coco-pellet gasifier stove technology is another output of the research and development effort of the CPU Appropriate Technology Center of the College of Agriculture, Central Philippine University, Iloilo City, Philippines with the assistance from the following agricultural engineering students Job Cordero, Jojie Garcia, Lucio Larano, and Ruel Hamor. This gas stove was developed with the aim of providing domestic households another low cost technology for cooking using biomass waste as fuel. By using limited amount of air injected into fuel, a combustible gaseous fuel is produced consisting of CO, H₂, and CH₄. However, because of high amount of volatile matter in cocopeat, the burning gas produces a yellow-to-pink flame.
