The document describes the design, fabrication, and performance evaluation of a domestic gas oven. Key points: - The gas oven was designed using 3D modeling software and fabricated from stainless steel, aluminum, and insulating materials like silicone rubber and asbestos. - Testing showed cakes baked in 28 minutes at 180°C, cookies in 10 minutes at 150°C, and muffins in 13 minutes at 180°C, demonstrating higher energy efficiency. - The oven operates using natural convection heat transfer from its gas burner. Results found it effectively baked foods with acceptable quality while reducing energy use, costs, and baking time.
