DEVICE AND METHOD FOR THE THERMOCHEMICAL HARMONISING AND GASIFICATION OF WET BIOMASS

摘要

The invention relates to a device for producing an energy carrier and/or raw material carrier from moisture-containing and/or dry biomass with the aid of a heatable carbonisation reactor (1) having a closable inlet opening (13). The biomass is converted in the carbonisation reactor (1) into a solid, pourable or gaseous energy carrier and/or raw material carrier and for interim storage of the energy carrier and/or raw material carrier is then delivered via a closable outlet opening (14) to a coolable tank (9) connected to the carbonisation reactor (1). The tank (9) is connected to an adjoining heatable gasification reactor (16), in which gas and waste substances, such as ash, are separated from the energy carrier. The device is characterised by the following features: a) the carbonisation reactor (1) is surrounded by a heating jacket to which external thermal energy is fed and to which further thermal energy at least from the gasification reactor (16) is fed; b) cooling energy is fed to the gasification reactor from a second tank or cooling tank (9); c) water is fed to the second tank or cooling tank (9) in order to ensure an approximately constant humidity, at least for the charcoal production; d) reaction gas is fed from the carbonisation reactor (1) and/or the second tank or cooling tank (9) to a gas storage facility (20).
