Goal
Provide a high-efficiency cooking stove that dramatically reduces fuel consumption and emissions, especially for low-income households.
Problem
Inefficient, polluting traditional wood-fuel stoves that cause deforestation, health problems, and excessive time spent gathering fuel.
Concept Summary
A stainless-steel stove with a tubular combustion chamber divided into two sections, a pressurized air chamber below it, and multiple air injectors mounted on concentric flat rings. Replaceable central parts adapt the device to solid, liquid, or gaseous fuels. A fan supplies pressurized air, creating a rotational airflow that improves combustion efficiency and heat transfer while minimizing pollutants. Thermal insulation cylinders surround the combustion chamber.
Detailed Description
The invention comprises a cylindrical combustion chamber (lower and upper sections) with a pressurized air chamber underneath. Air injectors are supported on a first flat ring and a second flat ring, allowing sliding motion to avoid deformation at high temperature. A set of replaceable parts (including a central air injector) sits between the rings and is configured according to the fuel's physical state. Fans below the air chamber regulate airflow, and a thermal insulation system of concentric cylinders reduces heat loss. The design aims for up to 95 % fuel savings compared with conventional wood stoves.
