SOOTBLOWER NOZZLE ASSEMBLY WITH NOZZLES HAVING DIFFERENT GEOMETRIES

摘要

In accordance with the teachings of the present invention, a sootblower design incorporates a downstream nozzle (308) positioned on a nozzle block (302) body and an upstream nozzle (310) positioned longitudinally from the position of the downstream nozzle (308) farther from a distal end (307) of the nozzle block than that of the downstream nozzle (308). The upstream nozzle (310) has a geometry that is different than the geometry of the downstream nozzle (308). By having nozzles (308, 310) of different geometries, each nozzle (308, 310) can be individually optimized for the flow conditions each nozzle (308, 310) experiences.
