MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202611056498 A) filed by Graphic Era Deemed To Be University on May 04, 2026, for A System And Method For Dual-Fuel Gasification Cooking Using Multi-Stage Airflow, Smoke Recirculation, And An Insulated Dual-Zone Combustion Chulha.
Inventors include Man Vir Singh; and Subham Sharma.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: The invention relates to solid-fuel cooking systems, and particularly to a dual-fuel gasification chulha operable with wood and coal. The system comprises a base and insulated outer body with an inner wall, an ash chamber communicating with a primary air inlet, a grate above the ash chamber, a primary combustion chamber for a layered fuel bed, a rotating air control ring for regulating primary airflow, a secondary combustion chamber, circumferential secondary air inlets, tertiary air inlets, a smoke recirculation channel, and a pot support ring defining an annular heat transfer passage around a cooking vessel, with an optional chimney. In operation, primary air supports under-fire combustion, while combustible gases rise to the secondary combustion chamber and receive secondary and tertiary air for staged oxidation. Partially burnt smoke and unburnt gases are redirected through the smoke recirculation channel to a hotter region for re-burning, thereby improving thermal efficiency, combustion completeness, and emission reduction.
