Abstract (en)
[origin: EP0710797A2] The mixture (25) of pilot gas (10) and air (17) for combustion is conveyed to a converter (21) inside the fuel lance (8) at the tip of the burner (2) for ignition and burning. The main burner gas (4) is supplied to the burner via a main gas pipe connected to the burner, and the pilot gas is supplied by a separate inflow pipe via the lance. The current of hot gas is mixed with the colder main current of gas inside the burner. The pilot gas is fed under pressure by a jet pump (22) integrated with the fuel lance. A sufficient quantity of combustion air is supplied from the plenum chamber outside the burner cap (6) into the lance, and pre-mixed with the pilot gas.
