Abstract: A domestic cooking stove comprises a frame that mounts a primary tube, one or more of nozzles for fuel injection, knobs for controlling the fuel injection, mixing tubes for modulating pressure gradient, burner tops for combustion of the air fuel mixture, and pan supports to support the vessel, heat reflectors to reflect heat, and legs to support the frame. Each heat reflector is positioned above burner top to provide secondary air entrainment for combustion by reducing a gap between an inner circumference of heat reflector and an outer circumference of the burner top to minimize heat losses. The heat reflector has a curved orientation to reduce heat transfer in a downward direction and generates eddies that increases heat transfer towards vessel bottom. The legs are positioned below the frame and has a predetermined height to maintain a gap between table top and the frame bottom surface for entrainment of air.
