Abstract

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.

设计一种创新的节能炉灶，减少空气污染，提高可持续性

本研究提出了一种节能炉，旨在减少有害物质的排放，从而改善农村家庭的室内空气质量。传统炉灶是家庭空气污染的一个重要来源，与呼吸系统和其他健康问题有关。这款炉灶的创新设计最大限度地减少了排放，最大限度地提高了热效率，直接解决了减少室内空气污染的挑战。设计/方法/方法改进后的炉子使用固体生物质燃料，其创新设计旨在提高燃烧效率和减少排放。木材被用作主要燃料，而过热的蒸汽被引入燃烧区，以帮助减少颗粒物质。炉子利用太阳能风扇调节气流，改善燃烧条件。与通过烟囱的自然浮力驱动的气流不同，风扇根据操作条件，通过增强进气量或支持排气过程来帮助控制气流动力学。研究结果：过热蒸汽通过促进一次燃料更好的混合和火焰温度来提高燃烧效率，从而使燃烧更完全，减少排放。此外，蒸汽的存在有助于炉子内更好的传热，导致整体热效率的提高。
