摘要:
Air cleansing apparatus includes an electrostatic precipitator in which the collector plates are made of, for instance, reticulated chemical vapor deposited silicon carbide, or reticulated silicon carbide ceramic coated with titanium nitride, zirconium diboride, or chemical vapor deposited silicon carbide. Microorganisms entrained on the collector plates are thermally degraded or vaporized by microwave radiation directed against the plates during a sterilization period which follows a collection period.
摘要:
A gas turbine component subject to extreme temperatures and pressures includes a wall defined by opposite first and second surfaces. An airflow aperture through the wall is defined by an aperture wall surface which extends from a first opening in the first surface to a second opening in the second surface. The aperture wall surface is flared at a juncture with the first surface, such that the first opening has a greater cross-sectional flow area than the second opening. A high-pressure, high-temperature coating is adhered to the first surface, and adhered to at least a portion of the aperture wall surface.
