Abstract (en)
[origin: WO2010057929A1] The invention relates to a closed hearth comprising a substantially closed combustion chamber and a system for supplying air and discharging burnt gases that is connected to said combustion chamber and includes an air supply circuit which has a forced air circulation device (18, 30), and a burnt gas discharge circuit. The supply and discharge circuits are in contact over one or more common segments (6) downstream of the forced air circulation device (18, 30) in order to exchange heat between the air and the burnt gases. The closed hearth is characterized in that said system for supplying air and discharging burnt gases also includes a control unit (24) for the forced air circulation device (18, 30), said control unit (24) being connected to a flow rate sensor (25) and being designed to control an air flow rate in such a way that the minimum combustion factor ? in the combustion chamber amounts to 1.5.
