Spraying nozzle for injecting cooling and wash waters into hot dust and clinker-prominent gasification gas in quenching chamber, has nozzle head arranged behind inner shell, where nozzle is surrounded by sheath that extends over head

摘要

The nozzle (1) has a nozzle head (9) arranged behind an inner shell (2) around 1-4 times of a nozzle diameter. The nozzle is surrounded by a tubular protective sheath (5) that extends over the nozzle head of the nozzle around the 1-4 times of the nozzle diameter. The nozzle is bent downwards, where an annular space between the nozzle and a protective sleeve is rinsed by a sweep gas (10). The protective sheath is closed by the inner shell, and the nozzle is inserted and removed from outside of a pressure cladding (4) and connected with a quenching chamber (8) over a flange connection (7).
