Document Type and Number:
WIPO Patent Application WO/2016/098385
Kind Code:
A1
Abstract:
The present invention controls an inlet temperature 14a to be a set temperature of an acid dew point or higher such that: a combustion gas bypass line 12 that allows combustion gas to bypass a preheater 4 is provided, and a combustion gas flow rate adjustment damper 13 is provided on the combustion gas bypass line 12; the inlet temperature 14a of a dedusting apparatus 6 is measured by a thermometer 14; the inlet temperature 14a measured by the thermometer 14 is then inputted to a control unit 15; and an opening degree adjustment signal 13a is outputted from the control unit 15 to the combustion gas flow rate adjustment damper 13 on the basis of a comparison result between the measured inlet temperature 14a and the set temperature of the acid dew point or higher preset at the control unit 15.
