Abstract: A modular dust collection plate assembly (10) for use in an electrostatic precipitator is provided. The dust collection plate assembly (10) includes at least one panel member (100) and at least one waveform member (200) releasably coupled together. The panel member (100) is characterized by a substantially planar contour, having first and second faces on opposing sides thereof which are commonly bounded laterally by a pair of lateral edge portions (110, 110) extending in a longitudinal direction. The waveform member (200) also extends in the longitudinal direction and is characterized by a predetermined curvilinear cross-sectional contour that enables the waveform member (200) to disrupt at least a portion of the gaseous flow that would pass across it during operation in an electrostatic precipitator.

Abstract: A fan blade protection system (100) is provided for substantially preventing erosion by particulate impingement on the fan blade. Fan blade protection system (100) includes an outer erosion resistant layer (110) laminately bonded to an elastomeric energy dissipative layer (120). The laminate structure of fan blade protection system (100) is bonded to a portion (12) of fan blade (10). The outer erosion resistant layer (110) is formed of a material having a high yield strength such that it elastically deforms on impact by high velocity particulates. The energy transferred to the outer erosion resistant layer (110) is absorbed and distributed by the elastomeric energy dissipative layer (120), minimizing the force transmitted to the surface of the fan blade.
