Patent number: 11008911Abstract: A scrubber for exhaust gas cleaning onboard a marine vessel, comprising a scrubber shell (12) forming a scrubber chamber; and a tubular pipe (18) running through the scrubber shell for feeding scrubber liquid into the scrubber chamber; a concave bowl (32) for connecting the tubular pipe to the scrubber shell, the concave bowl having the shape of a solid of revolution, and the shape curving smoothly from the rim (46) of the concave bowl to the bottom (48) of the concave bowl. The tubular pipe runs through the bottom of the concave bowl in such a way that the bottom encircles the tubular pipe, and the tubular pipe and the bottom are connected to each other. The concave bowl is placed in an opening (34) in the scrubber shell in such a way that the scrubber shell encircles the rim of the concave bowl, and the scrubber shell and the rim are connected to each other.Type: GrantFiled: December 15, 2020Date of Patent: May 18, 2021Assignee: Valmet Technologies OyInventors: Kalle Hannula, Heikki Airikkala, Jere Fabritius, Juha Ojanperä, Kari Mäkelä

Patent number: 9551368Abstract: Spooling machine including two side frames spaced at a horizontal distance by a telescopic spacer beam, each frame having a pintle on supports for bearing a drum for cable pipe or hose, the telescopic spacer beam including at least one outer tube and at least one inner tube, which are slidably and telescopically one inside the other, and a locking device positioned between the outer tube and the inner tube for locking the outer and inner tube in adjustable position. The locking device includes a split part of the inner tube extending over a part of the length of the inner tube and dividing the inner tube into sections, and a force element for creating a swelling force on the split part of the inner tube to press the sections against the inner surface of the outer tube.Type: GrantFiled: August 13, 2012Date of Patent: January 24, 2017Assignee: MAILLEFER S.A.Inventor: Kari Mäkelä

Patent number: 9371987Abstract: A method for reducing corrosion of a superheater of a steam boiler. The superheater includes a superheater piping. The superheating piping includes a steam pipe where the steam to be superheated is directed. The steam pipe is separated by a protective shell having a surface settling in the flue gas space has a temperature that rises above an upper critical temperature, above which temperature in the flue gas space the compounds from the fuel are substantially in a gaseous form. A superheater of a steam boiler and a circulating fluidized bed boiler.Type: GrantFiled: December 27, 2005Date of Patent: June 21, 2016Assignee: Valmet Technologies OyInventors: Pertti Petänen, Kari Mäkelä, Kari Kuukkanen, Ari Kokko

Publication number: 20130068175Abstract: A boiler and a method in a boiler producing thermal energy, the method including: combustion or fuel and combustion air in the furnace of the boiler, delimited by walls; receiving of thermal energy by a steam superheater placed on the wall of the furnace and including at least one heat exchange surface, and supplying of gas or a gas mixture to the front of said heat exchange surface to form a barrier layer for protecting the heat exchange surface from flue gases developed in connection with the combustion. At least one supply device is provided in the superheater or in the direct vicinity of the superheater, to supply gas or a gas mixture to the front of said heat exchange surface to form a barrier layer to protect the heat exchange surface from the flue gases in the boiler.Type: ApplicationFiled: April 21, 2011Publication date: March 21, 2013Applicant: METSO POWER OYInventors: Asko Rantee, Kari Mäkelä, Kari Jääskeläinen

Publication number: 20110259284Abstract: A boiler (1) comprising at least: a furnace (2), in whose lower part the combustion used as the primary source of thermal energy of the boiler is configured to take place; devices (6) for supplying fuel into the furnace; devices (3, 7, 8, 26) for supplying combustion air into the furnace; one or more flue gas ducts (11); at least one chamber (17) accommodating at least one steam superheater (15) for recovering thermal energy. Said chamber is configured to allow a direct line of sight (16) between said superheater and said primary source, to enable the reception of thermal energy by means of thermal radiation. Said chamber is further configured to prevent the entry of said flue gases (19) to said superheater either totally or almost totally, to avoid the reception of thermal energy by convection.Type: ApplicationFiled: April 21, 2011Publication date: October 27, 2011Applicant: Metso Power OyInventors: Asko Rantee, Kari Makela, Kari Jaaskelainen

Publication number: 20060065173Abstract: A method for shielding the inner surface above the shield refractory (4) of the furnace wall (3) of a circulating fluidized bed boiler from erosion caused by suspension flows, in which method a shield structure is formed on the inner surface of the boiler wall. At least a first zone (1) and a second zone (2) are formed in the shield structure, the erosion-resistance properties of which zones differ from each other. In addition the invention relates to a circulating fluidized bed boiler, which comprises a corresponding shield structure.Type: ApplicationFiled: September 23, 2005Publication date: March 30, 2006Applicant: KVAERNER POWER OYInventors: Kari Makela, Kari Kuukkanen

Patent number: 5855736Abstract: Method of reducing corrosion in a power boiler of a pulp mill using biofuel and suspended matter obtained from the waste water treatment of the mill. In the method flue gases obtained from a waste heat boiler are fed into the power boiler, causing the sulfur dioxide contained in them to react with the alkali chlorides in the boiler and the chlorine to form hydrogen chloride.Type: GrantFiled: October 28, 1996Date of Patent: January 5, 1999Assignee: Kvaerner Pulping OyInventors: Esa Pikkujamsa, Keijo Salmenoja, Kari Makela, Jouni Kinni
