PROBLEM TO BE SOLVED: To provide a microwave supplying apparatus to a high-temperature and high-pressure vessel free from the restriction of windows. SOLUTION: The microwave supplying device for promoting chemical reaction to the high-temperature and high-pressure vessel consisting of a hollow wave guide or coaxial line which is hermetically closed by two partition windows respectively installed with the first window in an aperture and the second window on the outer side of the vessel, is so formed as to allow the control of the internal pressure between the first window and the second window and is so controlled as to make the internal pressure between the first window and the second window equal to the internal pressure in the vessel preferably under high- temperature and high-pressure conditions. The wave guide, etc., described above are introduced into the vessel and their apertures come into direct contact with the materials to be heated in the vessel to efficiently heat the arbitrary positions of the materials to be heated. A plurality thereof are introduced into the materials to be heated in the vessel at need so that the materials to be heated of a large capacity may be uniformly heated over a wide range. A plurality of the wave guides, etc., described above are arranged along the flow into the pipeline as the vessel so that the flowing materials to be heated can be continuously heated. A window for observation is mounted at the vessel at need to allow visual observation, observation by a fiber scope and spectral measurement in real time.
