It can be used in an odorless state, and combustion continues even with ultra-high pressure air. The combustion gas becomes extremely hot, so MHD power generation becomes possible. If high-pressure water is injected into the burner burning at high temperature, high temperature can be achieved. High-pressure steam is continuously obtained, and various high-speed heating devices and steam turbines are rotated to produce an extremely inexpensive power generator. Since the burner according to the present invention has basically the same structure from large thermal power generation to general small thermal equipment, there is no difficulty in design, and there is no failure since there are no movable parts.
