HEAT STORAGE BODY MAINTENANCE TIME NOTIFICATION APPARATUS FOR REGENERATIVE BURNER

摘要

To provide a heat storage body maintenance time notification apparatus for a regenerative burner and a heat storage body maintenance time notification method for a regenerative burner as well as to provide a remodeling method for a combustion furnace equipped with a regenerative burner, where the apparatus and methods can appropriately give notification about maintenance time of the heat storage bodies. Solution A heat storage medium (heat storage body)maintenance time notification apparatus includes a supply flow meter 11 adapted to measure a flow rate of combustion air flowing through a regenerative burner 5 equipped with a heat storage unit 3 containing heat storage media3a adapted to preheat combustion air supplied into a combustion chamber 2 of a combustion furnace 1, using exhaust gas discharged from the combustion chamber; a supply flow control valve 9 regulated so as to open and close based on the flow rate of the measured combustion air; a controller 12 adapted to detect an opening position of the control valve when the combustion air flows at a predetermined flow rate; and a notification unit 17 adapted to give notification that it is time for maintenance of the heat storage media of the heat storage unit when the detected opening position of the control valve becomes larger than a preset opening position based on correlation information between flow rate data on combustion air measured with the flow meter and opening position data on the control valve detected by the controller.
