Entrained-flow reactor for generating synthesis gas

摘要

Entrained flow reactor for producing synthesis gas from a carbon-containing fuel with an outer pressure-bearing reactor wall (1), which - a reaction chamber for the formation of raw gas and slag, - a cylindrical cooling screen (2), which delimits the reaction chamber from the reactor wall (1) is formed by cooling water flowable tube windings and has a conical lower section - an annular space (16) between the cooling screen (2) and the reactor wall (1), which can be flushed with an inert gas, - a quench chamber (17) adjoining the reaction chamber, in which the Raw gas is cooled in contact with water, and - a funnel-shaped body called slag drain body (6) for overflowing raw gas and slag from the reaction chamber into the quench chamber (17), which continues the conical lower section of the cooling screen (2) and a central opening encloses between reaction chamber and quench chamber (17), the slag drain body (6) comprises a funnel-shaped tube winding with protective coating through which cooling water flows, characterized in that - a horizontal intermediate floor closes off the quench chamber (17) at the top, the intermediate floor at the level of the slag drain body (6) from the reactor wall (1) to the slag drain body ( 6) extends and is connected in a gas-tight manner to the reactor wall (1) and the slag drain body (6), - an annular plate (8) is gas-tightly connected to the cooling screen (2) and a collar winding (19) of the slag drain body (6) and all cooling water supply lines and Cooling water discharge lines within the reactor, which are assigned to the cooling screen (2) and the slag drain body (6), are led into the reactor above the intermediate floor and are connected to the tube windings of the cooling screen (2) and the slag drain body (6) above the intermediate floor.
