DEVICE AND A METHOD FOR MANAGING UNBURNED RESIDUES IN REGENERATIVE BURNERS, A BURNER INCLUDING SUCH A DEVICE

摘要

A device for managing unburned residues, the device comprising a regenerator (5) having one end connected to a combustion enclosure (3) and an opposite end connected to a fuel admission pipe (4) and a flue gas exhaust pipe (8), the pipes being fitted with valves (2; 10) to alternate between an admission stage and an exhaust stage through the regenerator. A purge circuit (1) connected to the regenerator (5) acts before the exhaust stage to purge the regenerator of the fuel that it contains. The invention provides a corresponding method of managing unburned residues and a burner including such a device.
