PROCESS AND DEVICE FOR IMPROVING OF SYNTHESIS AND/OR FLUE GAS VELOCITY FIELD FOR REFUSE DERIVED FUEL APPLICATIONS

摘要

Process and device for improving of synthesis and/or flue gas velocity field solves technical problem of local increase of velocity and resulting non-homogeneous flue gas field resulting in uneven temperature and concentration distribution within flue gas field by providing for homogenization of flue gas field using strategically placed obstacles in the flow field such as flaps or similar devices. This system deals with refuse derived fuel ("RDF") or other type of waste or similar matter which is to be incinerated and generates more energy than used for decomposition. Device according to this invention is comprised of primary chamber (1), grate, preferably moving (2), input of primary air (3), input of recirculation air (4), secondary chamber (5), input for secondary air (6), input for tertiary air (7), position of increased velocity (8), (9), (10), (11), and unhinged, and hinged flaps to serve as obstacles.
