Device and method for controlling unburnt substances for regenerative burners, burner comprising such a device

摘要

The device has a regenerative tray (5) whose one end is connected to a combustion chamber (3) and another end is connected to a fuel inlet line (4) and a smoke exhaust pipe (8). The fuel inlet line is equipped with valves (2, 10) to alternate an intake phase and an exhaust phase through the regenerative tray. A purge circuit (1) is connected to the regenerative tray to purge the fuel containing the regenerative tray before the exhaust phase. The purge circuit includes a gas ejector (1.3). An independent claim is also included for a method for managing unburnt residue.
