The subsidiary combustion chamber includes an inwardly tapered frustconical tube and an outwardly tapered air chamber surrounding the frustconical tube and communicating with the tapered air chamber. The frustconical tube of a diffusion-depression type includes a fire outlet exposed to outside of the body, a inwardly tapered fire inlet faced to the preheating burner, a plurality of heat resistant and antioxide metal strips extending from the fire inlet to the fire outlet, an air discharging tube disposed along the center line of the frustconical tube at rear of the frustconical tube and provided at its peripheral portion with a plurality of air ports, a connecting tube connected to the air discharging tube to extend vertically across the air discharging tube and communicate with the tapered air chamber.
