HEATING FURNACE COMBUSTION CONTROL METHOD, HEATING FURNACE AND HOT ROLLING LINE

摘要

PROBLEM TO BE SOLVED: To provide a heating furnace combustion control method that can set a mixture ratio of combustion air to fuel gas (supply flow rate of combustion air) to a proper value in controlling combustion of a heating furnace even when a state of a fuel gas to be supplied (supply flow rate, calorific value, consistency) varies, and to provide a heating furnace and a hot rolling line.;SOLUTION: A heating furnace combustion control method includes: measuring a flow rate, a calorific value and a consistency of a fuel gas to be supplied to a burner; and setting a flow rate of combustion air to be supplied to the burner based on those measurement values, in controlling combustion of a heating furnace.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
