A dust injection system for engine testing and related methods are provided. The system includes a carrier pipe that defines a fluid flow path between an inlet and an outlet and an injection nozzle disposed within the carrier pipe between the inlet and the outlet. The injection nozzle receives a slurry comprising dust particulates and a carrier liquid, and injects the dust particulates and the carrier liquid into the fluid flow path. The carrier liquid is atomized and evaporates in the fluid flow path prior to the outlet to enable dried version of the dust particulates to exit the outlet.

A coated component may have a consumable coating that protects the component from dust. A coated component may include a silicon containing substrate defining a substrate surface, a barrier coating on the substrate surface, with the barrier coating defining a barrier surface, and a consumable coating on the barrier surface. The consumable coating may include a ceramic oxide that includes a silicate. A component, such as a component of a turbomachine, may be protected from dust by applying a consumable coating on the component.

A porous membrane structure is disclosed, which includes a porous substrate, a mesoporous, aluminum oxide layer disposed on the substrate; and a relatively thin, continuous, microporous barrier layer disposed on the mesoporous aluminum oxide layer, also formed from aluminum oxide. The membrane is capable of improving hydrogen selectivity within a gas stream, e.g., a synthesis gas composition. Membrane supports containing these structures are also described, as well as gas separation modules, and related processes. Power plants which incorporate the gas separation modules are also disclosed herein.
