PURPOSE:To facilitate to change a cone by dividing a cone into two parts and constituting the top part to be detachable, in the titled burner for drying at the time of work to construct a refractory furnace for use of industry. CONSTITUTION:When a part 26 is fitted to the cone 27 of a high velocity burner, hooked metal fittings 26a of a change part 26 are inserted halfway into the projections 25a of a shell part 25, with the shell part 25 being fitted to a main pipe 21, and the part 26 is pulled to the side of an injection port, after the part 26 is turned round until the hooked metal fittings 26a come to contact with the projections 25a. By this procedure, the change part 26 is jointed to the shell part 25 with a part overlapped to each other. The part 26 can be detached by a reverse procedure. With such an arrangement, the efficiency of work can be increased. |
