Patent number: 11597888Abstract: A method and apparatus for production of cellulose based fuel pellets from wood logs includes steps of comminuting the wood logs to particulate wood material. The particulate material heat treated in a reactor and the pressure is reduced in a manner causing defibration of the particulate material. The material is pelletized using the softened lignin at least partially as a binder for the pellets. The comminution of the wood logs is effected as a single-step operation in which the wood logs are charged to a comminution station where at least one rotating drum provided with cutting teeth is arranged in a manner to fully comminute the wood logs. The particulate material may be fractioned and a selected size fraction used for the further treatment.Type: GrantFiled: August 15, 2018Date of Patent: March 7, 2023Assignee: Arbaflame Technology ASInventor: Rune Brusletto

Publication number: 20200017788Abstract: A reactor (3) which accommodates a biomass raw material (B1) and heats and decomposes the biomass raw material (B1) using steam (S); an offgas duct (18) through which offgas (G) generated from the biomass raw material (B1) in the reactor (3) flows; a steam generator (4) which combusts the offgas (G) from the offgas duct (18) to generate the steam (S) and supply the steam (S) to the reactor (3); a supply valve (8) which cuts off the reactor (3) from outside air; an offgas valve (19) which adjusts a flow rate of the offgas (G) in the offgas duct (18); a discharge unit (20) which discharges a processed biomass (B2) produced by heating and decomposing the biomass raw material (B1) in the reactor (3); a discharge valve (21) which opens and closes the discharge unit (20); and a control device (7) which controls the offgas valve (19) so that the offgas (G) is able to be discharged to the offgas duct (18) by depressurizing the reactor (3) at a depressurization speed at which no blasting occurs are provided.Type: ApplicationFiled: November 25, 2016Publication date: January 16, 2020Applicant: ARBAFLAME ASInventors: Yuki Endo, Rune Brusietto

Patent number: 10287525Abstract: Method and apparatus for preparation of fuel from biomass wherein the biomass is subjected to a heat treatment in a temperature range from 150 to 300 C, in a reactor pressurized with steam and air, wherein the pressure at completed treatment is released. The volume increase of steam and other gases from the pressure release is temporarily accumulated in a container of a flexible volume while steam and other gases are subjected to heat exchange in at least one heat exchanger so that condensable gases are condensed and release their heat of condensation in the at least one heat exchanger.Type: GrantFiled: February 19, 2014Date of Patent: May 14, 2019Assignee: Arbaflame Technology ASInventors: Rune Brusletto, Wolfgang Plückhahn

Patent number: 10119088Abstract: The present invention provides a carbon-enriched biomass material, a method of producing the carbon-enriched biomass material, and a method for using the carbons-enriched biomass material. A lignocellulosic material is used as a starting material and is treated at elevated temperatures under partially oxidizing conditions in a reaction vessel which is isolated from the environment. The carbon enriched biomass can be used in domestic or industrial combustion processes.Type: GrantFiled: February 5, 2014Date of Patent: November 6, 2018Assignee: Arbaflame Technology ASInventors: Rune Brusletto, Mike Kleinert

Patent number: 8585785Abstract: A method for production of fuel pellets from a biological material, preferably saw dust, wood or similar, where the method comprises the following steps: supplying the material to a drying step (1) and dry the material to a relative humidity from 40-65 weight-percent to 30-45 weight-percent; supplying the material from the dryer step (1), optionally via an intermediate storage step (2), to a reactor step (3, 3?) and heat the material to 200-300° C. by supply of steam; keeping the material in the reactor at the achieved temperature in sufficient time to soften the material; reducing the pressure of the reactor step (3, 3?) in at least two steps, in order to defibrate the material and release of lignin, and supply the material from the reactor step (3, 3?) to an additional drying step (5), optionally via an intermediate storage step (4), and optionally pelletizing of the material.Type: GrantFiled: June 16, 2005Date of Patent: November 19, 2013Assignee: Arbaflame Technology AS and Cambi Technology ASInventors: Rune Brusletto, Odd Egil Solheim, Hans Rasmus Holte
