Fuel Nozzle Assembly Flushing After Ultrasonic Cleaning

The patent applies preliminary action by first performing ultrasonic cleaning to loosen and remove deposits from the fuel nozzle assembly, then followed by a flushing operation using pressurized solution to clear residual debris from internal cavities. This sequential approach ensures that the preliminary ultrasonic cleaning prepares the surface for effective subsequent flushing, preventing residual debris from remaining in hard-to-reach areas.

The patent utilizes hydraulics by introducing a pressurized flushing solution through the fuel nozzle assembly after ultrasonic cleaning. The pressurized fluid flows through internal passages and cavities, carrying away loosened debris and residues that ultrasonic cleaning alone cannot remove. This hydraulic flushing action effectively eliminates residual debris from complex internal geometries.

The patent applies dimensionality change by introducing a fluid dimension to the cleaning process. Instead of relying solely on mechanical disassembly or surface-level cleaning, the method uses a pressurized flushing solution that penetrates into internal cavities and passages of the fuel nozzle assembly. This fluid dimension allows the cleaning agent to reach areas that are inaccessible to external cleaning tools, achieving complete debris removal while keeping the assembly intact.

The patent uses a flushing solution as an intermediary medium between the cleaning system and the fuel nozzle assembly. This intermediary fluid carries cleaning agents and flushes out debris from internal cavities without requiring direct mechanical access or disassembly of the assembly. The solution acts as a mediator that penetrates complex geometries and removes contaminants effectively.
