A gas outlet monitoring system for a boiler system includes a gas probe(s) with a plurality of gas sensing locations wherein each location measures a plurality of parameters of the gas flow, such a oxygen concentration and temperature. The multi-sensor probe includes a tubular lance and a plurality of sensor pods spaced along the lance. Each sensor pod has an oxygen sensor disposed in a first port, and a first temperature sensor disposed in a second port. An enclosure is disposed at one end of the tubular lance. The enclosure has a respective pressure sensor for each oxygen sensor port. A plurality of first tubes passes through the lance between the enclosure and the first port of a respective sensor pod to provide a gas to the respective first port for the purpose of providing cleaning air. A plurality of second tubes passes through the lance between the enclosure and the first port of a respective sensor pod to provide fluid communication between gas in the respective first port and the respective pressure sensor. One pressure sensor is provided for each oxygen sensor.

Disclosed herein is a scanning device for performing ultrasonic nondestructive testing of a tube, comprising a housing; the housing having bottom surface that is concavely curved with cavities to accommodate a waveguide assembly and an encoder assembly; where the waveguide assembly comprises a waveguide and a probe that are in communication with one another; the waveguide having at least one surface that is contoured to match an outer surface of the tube; where the waveguide facilitates the transmission of ultrasonic signals into the tube generated by the probe; and where the encoder assembly comprises a spring loaded wheel that contacts the tube; and where the encoder assembly provides a signal indicative of a location of the probe relative to a position on the tube as the scanning device is moved in a direction of a longitudinal axis of the tube.

A head assembly for a pulverized coal nozzle includes removeable wear-resistant inserts having vanes. The vanes may be flat or curved to direct a stream of air and pulverized solid fuel particles from the inlet port toward the outlet port. The curved vanes curve in two dimensions to evenly distribute the stream of air and pulverized solid fuel away from the outer surfaces reducing wear and corrosion. The pipe elbow has a removable cover that allows for easy access. The vanes are attached to a wear-resistant replaceable liner thus allowing them to be easily removed and replaced. The wear-resistant liner may be made from several parts for ease of removal and replacement.

A head assemblyfor a pulverized coal nozzle includes a turning vaneor a curved vanedisposed within a pipe elbow. The vanesare angled relative to the inlet port and the outlet port of the pipe elbow to redirect a stream of air and pulverized solid fuel particles from the inlet porttoward the outlet port. The coal rope-breaking vaneis pivotable about an axis to adjust an angle of the vanes relative to a stream of air and pulverized solid fuel particles from the inlet port. An adjustment barmay connect to the vanesand extend outward through the pipe elbow to allow the vanesto be adjusted while the pulverized solid fuel particles flow through the head assembly. The pipe elbow may further include inspection portsand a removable cover. The vanes may be attached to the removable coverthus allowing them to be easily removed and replaced.

A classifier [] is disclosed that employs adjustable vanes [] that may be interactively adjusted to change the distribution of fuel particle sizes that are passed on to a furnace. The classifier employs a frame [] having a plurality of windows [] each having an adjustable vane []. A control ring [] is rotated with respect to the frame [] to simultaneously move links [] connected between the control ring [] and the vanes []. This causes the vanes [] to open or close, changing the air flow path and changing the size distribution of particles passing through the classifier [] to the furnace. The system may include an adjustment system [] that can automatically sense particle size to optimize several physical parameters related to particle size.

A wear plate assembly includes a body portion and an abutment flange extending from a radially outer circumferential edge of the body portion and substantially normal thereto. The abutment flange is cooperatively configured with respect to another abutment flange of a respective adjacent wear plate that interengages with the wear plate such that a convoluted edge of the another abutment flange of the respective adjacent wear plate intermeshes with a respective convoluted edge of the abutment flange of the wear plate. At least one polygonal recess and a corresponding abutment ramp are substantially aligned therewith at a same latitude on the body portion, the recess further includes a through hole extending through the wear plate. A first clip configured is partially received in the polygonal recess, the clip having a plurality of exposed impact surface faces.
