Abstract:
More than 2.6 billion people throughout the world still lack access to clean cooking facilities, despite the robotic era of our technological world. Cooking on traditional stoves causes home air pollution from cooking smoke, which contributes to the 2.5 million premature deaths worldwide each year. In Pakistan 50.8% of the total population use traditional methods to cook by burning wood, animal manure and agricultural residue causing enormous greenhouse gases emissions. . These emissions contribute to the spread of illnesses. . An improved cooking stove (ICS) is one of the finest solutions to this problem, especially in Pakistan's northern regions such as Gilgit,
Baltistan, Ghizer, Skardu, and Ghance districts. ICS aids in complete combustion of biomass fuel to decrease hazardous gas emissions, improving overall efficiency, and lowering fuel consumption is proposed in the current studies for. The goal of this research was to design, fabricate, and test a Double Mouth ICS with a chimney and a hot water tank. The design was finalized after taking into account a variety of engineering and non-engineering factors such as material, cost, safety, portability, size,
fuel efficiency, fuel type, and interior air quality. Specific features were also included, such as a secondary burner for baking and a hot water tank to maximize waste heat recovery. 3D CAD modeling for development and manufacturing of prototype was done using Solidworks. The temperature distribution and heat flow from the stoves to the chimney were further checked using thermal simulations through3 different convective heat coefficients on a 3D CAD model using ANSYS. Materials such as mild steel and galvanized iron sheets are used to finish the fabrication. The stove's
construction material is chosen to be light and robust for mobility. This ICS will assist individuals in improving their indoor air quality, improving their health, and lowering their fuel costs. The performance evaluation during the experimentation on the prototype and the numerical analysis through thermal simulations for the validation of experimental results show that thermal efficiency, fuel saving, burning rate and fire power durability are promising. Conclusively, proposed ICS can help the communities of developing countries to make their life better in terms of good indoor air quality and better health.
