The authors could establish a method of discriminating the real state of gas combustion in an open hearth furnace by means of taking gas from some spot in the gas flame and analizing its chemical contents. By this method the following results were obtained in consequence of the experiments with respect to Venturi type acid open hearth furnace (nominal capacity 40t). (1) The velocity of gas combustion in the open hearth furnace was quantitatively measured by the variation of the quantity of CO content in the flame gas. (2) The combustion velocity is increased by the addition of air blowing and far more increased by the addition of oxygen blowing compared with that of gas only. (3) The combustion velocity was compared as follows by finding out the gas combustion velocity constant (K) in an open hearth furnace. (i) In the case of ordinary operation (gas only, excess air 15%)……K〓13 (ii) With the addition of air blowing (4m^3/min)……K〓37 (iii) With the addition of oxygen blowing (7m^3/min)……K〓66
