Abstract:
1. A particulate cleaning composition for on-line cleaning of surfaces hydrocarbon fuel burning gas turbine system a comprising: a high purity expandable coke or a mixture of high purity expandable cokes, a high purity non-expandable coke or a mixture of high purity non-expandable cokes, or mixtures of high purity expandable cokes and high purity non-expandable cokes, where: the coke particles have sizes ranging between about 0.01 microns (μm) and about 1,000 microns (μm), the high purity cokes are greater than 99% carbon, the expandable coke particles are capable of expanding up to about 150 times their initial volume when heated above a predetermined temperature, and the composition is capable of cleaning selected sections of a hydrocarbon fuel burning gas turbine system without significant loss of in system power production.
