Abstract: The invention relates to a process system and a method for preliminary treatment of disintegrated cellulose-containing material, preferably wood chips, prior to pulp digestion. The process system and the method according to the invention make use of a process vessel intended to function both as a so-called chip bin and as a pre-impregnation vessel. The characteristics of the invention are that a sloping steaming vessel is arranged downstream of the process vessel for the purpose of separating an excess of pre-impregnation liquid from the pre-impregnated cellulose-containing material, that the sloping steaming vessel is arranged for supplying steaming vapor which preferably has been generated by flashing of extraction liquor from a pulp digester, and that the sloping steaming vessel is connected to a chip chute communicating with a condenser for connection to a system for managing foul-smelling process gases.

Abstract: Portable turner for combustion of a gaseous fuel comprising an elongated combustion chamber (1), the front end of which is open and the back end of which is closed with a back (2) and that is connected partly with a fuel gas conduit (4) and partly with a combustion air conduit (5.1), and that is enclosed by a concentric cooling jacket (1.2) for the flow of a cooling medium. The cooling jacket (12) shows an exhaust opening at the open front end of the combustion chamber (1) and is connected with a cooling air conduit (5.2) for the delivery of cooling air, that in its turn is connected with a compressed air source. The compressed air source may consist of a cooling blower (10) that is connected with an air motor (9) via a shaft (10.1) and that is fed with compressed air from a compressed air conduit (5).
