Turbines and associated equipment are normally cleaned via water or chemical pressure washing via a mist, spray systems. However, these systems fail to reach deep across the gas path to remove fouling materials. Various embodiments herein pertain to apparatus and methods that utilize the water and existing chemicals to generate a foam. The foam can be introduced at that gas-path entrance of the equipment, where it contacts the stages and internal surfaces, to contact, scrub, carry, and remove fouling away from equipment to restore performance. Various embodiments pertain to spout assemblies for providing foam to the compressor of commercial fan engines, and in yet other embodiments to engines receiving air from a long inlet duct, especially those having a serpentine inlet ducts.
Turbines and associated equipment are normally cleaned via water or chemical pressure washing via a mist, spray systems. However, these systems fail to reach deep across the gas path to remove fouling materials. Various embodiments herein pertain to apparatus and methods that utilize the water and exiting chemicals to generate a foam. The foam can be introduced at that gas-path entrance of the equipment, where it contacts the stages and internal surfaces. In one embodiment, the method can include: forming a first foam with a liquid cleaning agent and pressurized gas; flowing the first foam over a member or matrix and increasing the size of the cells of the first foam to form a second foam; and flowing the second foam through a structure such as a mesh or one or more apertured plates and decreasing the size of the cells of the second foam to form a third foam.

Various embodiments herein pertain to apparatus and methods that utilize the water and existing chemicals to generate a foam. The foam can be introduced at that gas-path entrance of the equipment, where it contacts the stages and internal surfaces, to contact, scrub, carry, and remove fouling away from equipment to restore performance. Various embodiments include operating a gas turbine engine; measuring the performance of the engine during operation; determining that the engine should be foam washed based on the measurements; mixing pressurized gas with pressurized liquid and creating a supply of foam; and streaming the supply of foam into the engine.
