Abstract
A nozzle assembly for cleaning turbines includes an offline cleaning nozzle and a pair of online cleaning nozzles. The offline cleaning nozzle directs cleaning fluid towards the inlet of turbine. The online cleaning nozzles direct a cleaning fluid in a fan-shaped pattern in a direction substantially parallel to the direction of air flow within the turbine's inlet air duct, and intersecting with each other. The longest dimension of the fan-shaped spray pattern is substantially parallel to the direction of air flow within the duct.
