Process for supplying oxygen to fixed-bed reactors for producing a weak gas from biogenic substances

摘要

The invention relates to a method for supplying oxygen to fixed bed reactors, comprising an air blower (2) for sucking air, measuring pressure (12) and volume flow (13) of the sucked air, distributing the volume flow to four control valves (14, 15, 16, 17) ), the preheating of the individual volumetric streams via heat exchangers (18, 19, 20, 21) and the distribution of the air volume streams via a nozzle base (45) in the cross section of the reactor. The nozzle base consists of nozzle rings (22, 23, 24) via which the air is distributed, measuring the temperatures in the nozzle rings (25, 31, 26). The pressure (28) and the temperature (27) are measured by means of a cyclone (8) and are then fed to the gas purification unit (29) and sucked by a vacuum compressor (30) ) and volumetric flow (33).
