Abstract

The invention relates to a device and method for creating a fine-grained fuel from solid or paste-like raw energy materials by means of torrefaction, comprising an impact reactor having a rotor and impact elements which is temperature resistant up to 350 degrees Celsius, a feed device for hot circulation gas in the lower region of the impact reactor, a feed device for solid or paste-like raw energy materials in the head region of the impact reactor, at least one withdrawal device for a gas flow comprising comminuted and torrefacted raw energy particles and a separation and withdrawal device for crushed and torrefacted raw energy particles from the gas flow taken out of the impact reactor.

Description

technical field [0001] The present invention relates to the thermal pretreatment, ie torrefaction, of solid fuels containing carbon and hydrogen in an impactor reactor. In the following, said fuels (which may also have a pasty or viscous consistency) are referred to as solid or pasty energy feedstocks and include, for example, biogenic and other highly reactive fuels, fossil fuels and residues. Pastes refer to all materials comprising a mixture of solid and liquid components, examples being sludge and water-based or solvent-based industrial residues or energy-containing liquids such as oily substances or lubricants. There is a general drive to develop the use of renewable energy and to recycle waste and residues, where thermal gasification allows particularly efficient utilization from an energy and material point of view. Entrained bed gasification is particularly advantageous, the plants for which are usually of great capacity and also run on coal. The invention also enabl...
