Abstract

Improvements in firing furnaces with circulation heating, characterized by being made up of one or more superimposed firing chambers, with heating registers crossed by heating gases, arranged above and below the firing chambers, the registers of which are heated They are in communication, through vertical inlet and outlet channels arranged at the ends of the furnace, with a channel that closes the circuit of circulating heating gases driven by a blowing device, with a combustion chamber placed in said channel in the longitudinal axis of the baking oven, tubular, aligned parallel to the gas stream, with the burner, which serves to heat the heating gases, the inlet channels running through the door side and the channels outlet on the rear side, characterized in that the combustion chamber is arranged in the middle of the inlet channels, which form partial currents, and it is provided, for the transfer of the burner flame gases (A) to the inlet channels, with a lateral outlet opening for the burner flame gases (A) and is arranged in a rotating assembly around its longitudinal axis, in its entirety or at least with the part that carries the outlet opening.
