Abstract: A pyrolysis vapour condenser system (1) and a method for condensing pyrolysis vapour, the pyrolysis vapour condensing system comprising a condenser vessel (2), comprising a vapour inlet (3), and a cleaning device (9) for removing deposits from the vapour inlet (3). The cleaning device (9) is moveable between a cleaning position, in which it is disposed at least partially in the vapour inlet (3) for cleaning it, and a retracted position, in which the cleaning device (9) is retracted away from the vapour inlet (3) towards the condenser vessel (2).

Abstract: A device for pyrolysing biomass comprises: a reactor space; a first feed for biomass material connecting to the upper zone thereof; a second feed for heated heat carrier material connecting to the upper side of the reactor space; a first discharge for pyrolysis gas connecting to the upper zone of the reactor space at a distance from the first feed; and a second discharge for solid material, for instance carbon and heat carrier material, connecting to the underside of the reactor space. A substantial separation between the discharge flows of pyrolysis gas and solid material takes place predominantly under the influence of gravitational force, without interposing of a cyclone. The reactor space is modeled such that the direct flow from the first feed and the second feed to the first discharge is blocked. A mechanical mixer is present in the reactor space for the purpose of mixing the flow of biomass material with the flow of preheated heat carrier material.

Abstract: A method of pyrolysis wherein pyrolysable particles mixed with heated carrier particles are treated at an elevated temperature yielding a flammable product. According to the invention, use is made for mixing a rotating, vibrating or shaking element or by mixing at a volume density of less than 40%, and mixing occurs to a specified minimum degree after the mixture is deposited and is pyrolysed in the reactor after depositing.
