徴とする空気予熱器の温度制御装置。 In a temperature control device for an air preheater, the air preheater preheats combustion air using exhaust gas, and a temperature controller that adjusts the flow rate of a temperature adjustment fluid to adjust the temperature of the combustion air. A calculator is provided to calculate the average temperature of the detected temperatures from the air thermometer that detects the air inlet temperature of the preheater and the exhaust gas thermometer that detects the exhaust gas outlet temperature.
A function generator is provided to obtain a temperature setting signal by introducing detection signals from an SO 2 concentration detector that detects O 2 concentration and an O 2 concentration detector that detects O 2 concentration, and a function generator that obtains a temperature setting signal. A comparator for comparing the set signal of the function generator, and a regulator for adjusting the flow rate of the temperature regulating fluid of the temperature regulator so that the difference between the signals in the comparator becomes zero. Air preheater temperature control device.
