A High-Efficiency Clean Cookstove Designed for Processed Biomass fuel

Around 40% of the global population approximately half living in developed countries still rely on traditional biomass cookstoves for daily cooking. This widespread practice is a major source of indoor air pollution and adverse health effects due to the release of a hazardous pollutants such as particulate matter (PM2.5) and carbon monoxide (CO). According to the WHO report, there is an estimated 3.8 million death annually from indoor air pollution. In this study a mini biomass pellet based forced draft domestic cookstove was developed and experimentally evaluated for its thermal performance and the emission characteristics, using the standard water boiling test. The stove demonstrated a thermal efficiency of up to 47% with CO and PM₂.₅ emissions are as low as 2.97 g/kg and 256.16 mg/kg respectively. Therefore, there is 79% reduction in PM2.5, 95% reduction in CO emissions and efficiency is 400% higher than the traditional cookstove being used by 2.7 billion people globally. These results meet the Tier 4 efficiency criteria of the ISO/IWA clean cookstove standards. The developed cookstove shows promising result and provide effective and clean cooking solution to 1/3rd of humanity, particularly in the global south, while utilizing the carbon neutral fuel available locally.Keywords: Forced draft cookstove, Thermal efficiency, Emission of Carbon monoxide and Particulate matter
