METHOD OF CONTROLLING REGENERATIVE WASTE GAS TREATMENT EQUIPMENT AND REGENERATIVE WASTE GAS TREATMENT EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a regenerative waste gas treatment equipment provided with an exhaust heat recovery device capable of preventing the abnormal temperature rise in a combustion chamber even when a combustible element is contained in the waste gas to be processed. SOLUTION: This regenerative waste gas treatment equipment is provided with a by-pass means 2 for exhausting the gas in the combustion chamber 4 without passing the gas in a regenerator 3. The by-pass means 2 is provided with a first by-pass route 21 making the gas in the combustion chamber 4 pass in a heat exchanger 24 which heats a heating medium for exhaust heat recovery and exhausting, a second by-pass route 22 exhausting the gas in the combustion chamber 4 without passing the gas in the heat exchanger 24 and an exhaust amount adjusting means 23 capable of adjusting a first gas exhaust amount exhausted by the first by-pass route 21 and a second gas exhaust amount exhausted by the second by-pass route 22 individually. The exhaust amount adjusting means 23 adjusts the first gas exhaust amount based on the temperature or the pressure of the heating medium, and adjusts the second gas exhaust amount based on the temperature in the combustion chamber and the temperature or the pressure of the heating medium.
