Improved Biomass Cookstove: Thermal Efficiency Testing

Approx. component budget: Rs. 4,000 - 8,000

Objective

Improve a cookstove design and test it using the water boiling test to find efficiency, fuel use and time to boil.

What you will build

A sheet-metal cookstove with an insulated chamber, air inlets and a chimney, compared against a plain traditional stove.

Results you can expect

• Thermal efficiency (%)
• Fuel per litre of water
• Time to boil
• Comparison with a traditional stove

What you will learn

Combustion basics, heat transfer and design improvement with real data. Relevant to clean-cooking work.

Tools and notes

Thermometer, weighing scale, stopwatch. Test outdoors with good ventilation and fire safety.

Resume points from this project

• Built and tested Improved Biomass Cookstove: Thermal Efficiency Testing; objective: improve a cookstove design and test it using the water boiling test to find thermal efficiency, fuel use and time to boil.
• Measured and analysed thermal efficiency (%) and Fuel used per litre of water; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
