Design of an innovative fuel-efficient stove for reducing air pollution and enhancing sustainability

Purpose

This study presents a fuel-efficient stove designed to reduce harmful emissions, thereby improving indoor air quality in rural households. Traditional stoves are a significant source of household air pollution (HAP), which is linked to respiratory and other health issues. The innovative design of this stove minimizes emissions and maximizes thermal efficiency, directly addressing the challenge of reducing indoor air pollution.

Design/Methodology/Approach

The improved stove operates using solid biomass fuel, with an innovative design aimed at enhancing combustion efficiency and reducing emissions. Wood is used as the primary fuel, while superheated steam is introduced into the combustion zone to aid in particulate matter reduction. The stove utilizes a solar-powered fan to regulate airflow, improving combustion conditions. Unlike natural buoyancy-driven draft through a chimney, the fan assists in controlling the airflow dynamics by either enhancing the air intake or supporting the exhaust process, depending on operating conditions.

Findings

Superheated steam aids in improving the combustion efficiency of the primary fuel by promoting better mixing and flame temperature, thereby leading to more complete combustion and reduced emissions. Additionally, the presence of steam contributes to better heat transfer within the stove, causes an improvement in overall thermal efficiency.
