Gas Turbines

Gas Turbines are extremely susceptible to performance losses due to aerodynamic degradation caused by fouling. Even moderate fouling can cause losses of five percent or more. Heavy fouling can rob an engine of eight percent of its rated output. This problem can be solved by:

- in-service cleaning: typically a light application of dilute cleaner for 6 - 8 minutes 2 - 3 times per week. ECT’s custom injection manifolds control droplet size and prevent blade erosion. This mode of cleaning maintains clean airfoils throughout the compressor. Fouling is encapsulated by the detergent and blows out of the exhaust as a dry ash. ECT’s unique chemistry prevents redeposit on latter stages of the compressor.

- offline cleaning: done while the engine is at "crank" speed (usually about 1,000 rpm), the compressor case is flooded with cleaner and allowed to soak for about 20 minutes. This method facilitates cleaning the entire rotor from the first stage to the last. ECT’s specialty chemicals for gas turbines are completely environmentally friendly and require no special handling. ECT specialty chemicals for gas turbines includes:

- R-MC general purpose online/offline cleaner. R-MC is cationic amine-based, non-toxic, nonflammable, and completely effective in removing normal buildup of oils, dirts, salts, etc.

- PowerBack heavy duty offline cleaner. PowerBack offers the highest concentration of solids by volume of any gas turbine cleaner on the market.
