To improve the combustion effect in the open hearth furnace heated by the producer gas, the velocity of the combustion of the gas must be accelerated, and this acceleration is to be brought by the acceleration of the velocity of the mixing of gas and air, As this means, a method to blow compressed air gas port from both sides of the port through a water cooled pipe was tried in the first report. In this second report, a air jet type gas port which can blow primary compressed air into the gas port and gives the effect of explosion, combustion, just as like a Bunsen burner, was examined. By this improved method, good results as follows, as comoared with the former method was obtained. That is : 1) As the mixing rate of gas and air is much acceralated, the velocity of combusion is increased, and so, short and sharp flame is obtained. 2) The melting time is reduced by 20% 3) The fuel is saved by 15% during the melting time. 4) The flame direction and speed is easily controlled by the controlling of the pressure of compressed air.
