Air is blown from the air inlet 31, and water vapor generated by the steam generator 3 is injected from the steam injection nozzle 29 into the air/steam mixing chamber 6, resulting in a superhumidified state. At this time, the high temperature gas generated by combustion of the fuel in the burner 2 is cooled by heat exchange in the first heat exchange section 18, and the exhaust gas is sent to the second heat exchange section 25.

After this water vapor has been injected, the supersaturated water is separated by the water droplet separating plate 30, and the high temperature air sent from the high temperature air generator 4 is injected through the air nozzle 7 and heated in the outlet duct 12a, so that the air is brought out of the saturated state. A relative temperature of approximately 85% of the required temperature is assumed. That is, water droplets are separated from supersaturated air at low temperature by the water droplet separation plate 30 to form saturated air, and high temperature air is mixed into this saturated air to heat it.
Based on the results of measuring the temperature and humidity with the temperature and humidity measuring device 8, at least one of the air volume adjustment damper 11 and the high temperature air valve 26 is opened and closed, and if the high temperature air is required to be at a higher temperature.
