Reactor for cleaning flue gas by a dry or quasi-dry sorption process

Reactor for cleaning flue gases by injecting dry or quasi-dry sorbent into a flue gas stream, comprising

• a flue gas inlet at the bottom of the reactor,
• an outlet at the top of the reactor,
• a dry sorbent injection system with at least one dry sorbent outlet for injecting dry sorbent into the reactor, the at least one dry sorbent outlet being arranged between the flue gas inlet and the outlet, characterized in that
• a plurality of water injection nozzles are arranged beneath the at least one dry sorbent outlet, and in that
• the dry sorbent injection system has a plurality of dry sorbent outlets such that dry sorbent is injected at multiple locations, wherein the dry sorbent outlet has a lower discharge edge at which the flue gas stream flows along the dry sorbent outlet and at which the dry sorbent is injected into the reaction chamber, wherein the lower discharge edge extends back and forth, so that a length of the lower discharge edge projected in a vertical direction is greater than the width of the dry sorbent outlet.
