The figure is a diagram showing the relationship between the actually measured temperature and the opening degree of the adjustment valve when the thermocouple for measuring the temperature of the inner wall metal after the first stage is installed directly below the lower casing. Figures 8 and 9 are an example of an embodiment of the present invention. FIG. 2 is a configuration diagram showing the relationship between a thermocouple for measuring the temperature of the inner wall metal at the first stage and a control valve. 1... Taichita, 2...
