Abstract
Furnace for processes and treatments in a sub-stoichiometric atmosphere, includes a combustion chamber (1) provided with a fuel-feeding mechanism, feeding mechanism (3) for combustion promoter and an extraction mechanism (4) for the gases produced in the interior of the chamber (1). The feeding mechanism (3) for combustion promoter and the extraction mechanism (4) for the gases are connected, in an alternating way with suitable selection mechanisms (203, 213, 104, 114), to the furnace through at least one device (2) connected by a suitable mechanism (402) to an open port (121) on the combustion chamber (1) of the furnace. The device achieves post-combustion (102) of the gases, heat exchange and heat storage (112).
