The invention consists, while increasing the energy power of the gas, in carrying out the "cracking" of the tars by the use of immediately interchangeable temperature regulating components in the hearth, these simultaneously bringing about an ease of construction and of repair. The horizontal 4 and vertical 5 tuyeres are carried by a removable perforated distribution tube 3 resting on a stationary feed perforated distribution tube 1, it being possible for the tuyeres to be changed at will according to need. The temperature and cracking regulating ring 8 is also instantly demountable, the descending skirt 9 has a length determined with a coal filling ring 13, the upward return of the gases taking place via one or more vertical tubes in the hopper. <IMAGE>
