  • Patent number: 10684010
    Abstract: Burner assembly and method for combustion of gaseous of liquid fuel The invention relates to a burner assembly (1) and a method for combustion of gaseous or liquid fuel to heat an industrial furnace (9) having a combustion chamber (2), at least one main combustion air inlet (3) for the supply of preheat-ed combustion air (4) into the combustion chamber (2), a burner (5) with at least one fuel feed (7) and at least one air feed (8) for supply of fuel and primary air into a the combustion chamber (2), wherein the burner (5) is positioned adjacent to a combustion zone of the combustion chamber (2) such that the combustion air (4) flowing into the combustion chamber (2) through the main combustion air inlet (3) is passing the burner (5) in the combustion zone and is then deflected such that the flow of preheated combustion air and the smaller flows of fuel and primary air are flowing mainly in parallel from the burner (5) to the furnace (9), and a control unit for controlling the supply of fuel and maybe primary

  • Patent number: 9790570
    Abstract: An apparatus for the thermal treatment of lump or agglomerated material in a firing machine includes a travelling grate configured to convey the material through the firing machine. A firing chamber has a ceiling and side walls and is configured to generate temperatures required for the thermal treatment. The ceiling has a plurality of openings and the side walls have a plurality of burners that are directed obliquely upwards. A cooling zone is configured to pass cooling gases through the thermally treated material so as to heat the cooling gases. A recuperation tube is configured to recirculate the heated cooling gases to the firing chamber through the openings in the ceiling.
