A carbo-blast cleaning involves which method?

The process of carbo-blast cleaning specifically entails the removal of carbon deposits from various engine components, such as gas passages, blades, and nozzles. This method utilizes the kinetic energy generated by blasting a fine carbon medium to effectively dislodge and clean these deposits.

Using carbon black to clean a unit is not representative of this method, as carbon black is primarily a product and not typically used for blasting. The idea of removing carbon by blasting with solvents does not align with the principle of blasting, as solvents are designed to dissolve rather than physically remove deposits. Scrubbing the blades with rice, while a form of cleaning, is not an effective or standard industrial method for high-efficiency engines or turbines.

The clarity in this process lies in how it directs a carbon medium up against surfaces to clear carbon buildup, making it an efficient cleaning method for preserving the performance and efficiency of engine components.
