Abstract:
An alternate changeover regenerative burner system in a burner system operating with a quantity of combustion during rated operation after increasing temperature being set to be smaller than that during warm-up operation comprising:at least three or more units of alternate changeover regenerative burner for constituting a combustion system;one module unit of said alternate changeover regenerative burner including a burner having a regenerator, and an air supply/exhaust switching device for switching connection to an air supply system and an exhaust system of said burner;all of said units sequentially repeating alternate regenerative combustion with said units forming no fixed pairs;a ratio of the number of said burners performing combustion and the number of said burners being stopped being determined to be variable depending on said warm-up operation for increasing a furnace temperature and said operation after increasing the temperature; andsaid operation after increasing the temperature being carried out with said burners performing combustion whose number is smaller than the number of burners performing combustion during said warm-up operation.
