Patent number: 10710035Abstract: A feed mixture distribution device configured to even out a feed of feed mixture in an annular feed mixture feed channel of a burner. The feed mixture distribution device includes a cylindrical member having a cylindrical wall, a first end, a second end, and a longitudinal central axis X. The cylindrical member is at the first end provided with rectangular flat plate means, which extend radially from the cylindrical wall of the cylindrical member and which are arranged symmetrically about the longitudinal central axis X of the cylindrical member. The cylindrical wall of the cylindrical member is between the rectangular flat plate and the second end provided with helical plate means arranged symmetrically about the longitudinal central axis X of the cylindrical member.Type: GrantFiled: February 24, 2020Date of Patent: July 14, 2020Assignee: OUTOTEC (FINLAND) OYInventors: Peter Björklund, Kaj Eklund, Aki Laaninen, Jaana Romppanen

Patent number: 10655842Abstract: Provided are a burner such as a concentrate burner, a calcine burner, or a matte burner, or a burner using a mixture of these for feeding reaction gas and fine solids into a reaction shaft of a suspension smelting furnace, and a fine solids feeding apparatus for a burner such as a concentrate burner, a calcine burner, or a matte burner, or a burner using a mixture of these. The fine solids feeding apparatus comprises gas outlets in a fine solids discharge channel upstream of a downstream outlet end of the fine solids discharge channel. The gas outlets comprise spiral path guiding members configured to facilitate gas to flow from the gas outlets in a spiral flow path around a center axis A of the fine solids discharge channel.Type: GrantFiled: October 28, 2016Date of Patent: May 19, 2020Assignee: OUTOTEC (FINLAND) OYInventors: Peter Björklund, Elli Miettinen, Aki Laaninen, Sarianna Suominen, Kaj Eklund

Publication number: 20180156541Abstract: Provided is a burner such as a concentrate burner or a matte burner for feeding reaction gas and fine solids into a reaction shaft of a suspension smelting furnace. The burner comprises an annular fine solids discharge channel that is radially limited at the outside by a first annular wall and that is radially limited at the inside by a second annular wall. The annular fine solids discharge channel is configured to receive fine solids from a fine solids feeding arrangement and to create an annular flow of fine solids in the annular fine solids discharge channel. The annular fine solids discharge channel being provided with spreading means configured to be hit by the annular flow of fine solids and configured to even out particle distribution in the annular flow of fine solids.Type: ApplicationFiled: April 7, 2016Publication date: June 7, 2018Applicant: OUTOTEC (FINLAND) OYInventors: Elli MIETTINEN, Sarianna SUOMINEN, Lauri P.

Patent number: 9957586Abstract: The invention relates to a method of using a suspension smelting furnace and to a suspension smelting furnace and to a concentrate burner (4). The concentrate burner (4) comprises a first gas supply device (12) for feeding a first gas (5) into the reaction shaft (2) and a second gas supply device (18) for feeding a second gas (16) into the reaction shaft (2). The first gas supply device (12) comprises a first annular discharge opening (14), which which is arranged concentrically with the mouth (8) of a feeder pipe (7), so that the first annular discharge opening (14) surrounds the feeder pipe (7). The second gas supply device (18) comprises a second annular discharge opening (17), which is arranged concentrically with the mouth (8) of the feeder pipe (7), so that the second annular discharge opening (17) surrounds the feeder pipe (7) opening (14).Type: GrantFiled: March 24, 2015Date of Patent: May 1, 2018Assignee: Outotec OyjInventors: Jussi Sipilä, Markku Lahtinen, Peter Björklund, Kaarle Peltoniemi, Tapio Ahokainen, Lauri P.
