摘要： The present invention relates to a selective catalytic reduction (SCR) reactor assembly for removing fine particles that interfere with SCR catalyst activity in biomass fuel applications. The selective catalytic reduction (SCR) reactor assembly includes at least one turning vane disposed in a plenum chamber of the reactor, at least one rectifier layer disposed downstream of the at least one turning vane, and at least one active catalyst layer for removing particulate matter. The turning vane is adapted to impart a directional turn to the flue gas flowing through the reactor, and the at least one rectifier ensures even flow distribution.

摘要： A telescoping utility line pole is disclosed. The pole includes an outer pole section configured to be held in the hand of a user and having an inner bore defined by an inner surface and an inner pole section configured to slide within the bore of the outer pole section. The outer pole section includes a plurality of grooves defined by a plurality of raised sections positioned around a circumference of the inner surface. The inner pole section includes a plurality of lugs positioned on a distal end of the inner pole section. The plurality of lugs and plurality of grooves are keyed to each other. When the plurality of lugs are aligned with the plurality of grooves, the inner pole section is permitted to engage the outer pole section for use by the user.

摘要： A method of operating a thermal system including at least a compressor, a condenser, a flow control valve, and at least one heat exchanger connected in a closed fluid loop charged with refrigerant. The method includes: regulating refrigerant pressure at a selected point within the fluid loop using a pressure regulating apparatus including: a main pressure regulator including a dome in fluid communication with a diaphragm that seals directly against at least one process void and at least one vent void; and a pilot pressure regulator in fluid communication with the dome so as to provide fluid thereto at a setpoint pressure. The setpoint pressure is maintained by the pilot pressure regulator utilizing refrigerant tapped from the fluid loop The refrigerant is tapped from a point upstream of the main pressure regulator and tapped refrigerant is returned to the fluid loop downstream of the main pressure regulator.

摘要： A duplex turbine nozzle includes a row of different first and second vanes alternating circumferentially between radially outer and inner bands in vane doublets having axial splitlines therebetween. The vanes have opposite pressure and suction sides spaced apart in each doublet to define an inboard flow passage therebetween, and corresponding outboard flow passages between doublets. The vanes have different patterns of film cooling holes with larger cooling flow density along the outboard passages than along the inboard passages.
