Industrial furnace operation method, industrial furnace controller, and industrial furnace system

摘要

To provide an operating method of an industrial furnace, a controller of an industrial furnace, and an industrial furnace system capable of more reliably performing ignition of a burner by a simple operation.A method of operating an industrial furnace includes a plurality of burners, a first conduit, a plurality of second conduits branched from the first conduit and connected to the plurality of burners, respectively, a first conduit And a plurality of second valves provided in each of the plurality of second pipelines, wherein the pressure of the fuel between the burner and the first valve is set to be lower than the pressure of the fuel Sequentially igniting a plurality of burners by sequentially opening a plurality of second valves while performing a first control of controlling the opening degree of the first valve so as to follow one target value; And executing a second control of controlling the opening degree of the first valve so that the flow rate of the fuel passing through the first conduit follows the second target value after completion.(FIG.
