Cupola burner

摘要

A method and apparatus for controlling the operation of a plurality of burners of a cupola. The method includes the steps of separately supplying air and fuel to each burner of the cupola, measuring the flow rates of air and fuel supplied to each burner, controlling either the flow rate of air or flow rate of fuel supplied to each burner as a function of a desired heat energy output of the burners and controlling the other of the flow rate supplied to each burner as a function of the measured flow rate of air or fuel supplied to each burner and a preselected ratio of flow rate of air supplied to each burner and of flow rate of fuel supplied to each burner.
