DEVICE FOR THE PRESSURE RELEASE OF REACTORS FOR GASIFICATION OF POWDERED FUELS

摘要

A reactor for the production of gases containing CO and H2 by partial oxidation of liquid fuels or fuels in the form of dust, especially fuels with an ash content, using a gasification medium containing free oxygen, the process being effected at high temperatures and elevated pressure. In such a process the pressure jacket of the reactor must be reliably shielded from overheating and the effect of the crude gas and have a long life. This is achieved in that the wall of the reactor chamber (4) is formed from tubing (7) and surrounded by a gastight housing (8) which in turn is accommodated inside an outer pressure vessel (1). The gap between the housing (8) and the tubes (7) of the coil is filled in with a refractory clay material (19). Webs (16) secured to the inside of the housing divide this into a plurality of sections. The reaction chamber is connected to a space (11) between outer pressure vessel and housing by one or more openings (12, 13). The supply of an inert flushing gas is effected through at least one socket (22) to the space (11).
