A combustion control system [] for a combustion system [] having a plurality of fuel pipes []. The combustion control system [] including a plurality of flow meters [], a controller [], fuel flow controls [] and secondary air controls []. Each meter [] is adapted to monitor flow of fuel within a respective one of the fuel pipes [] by sensing a pressure field within the fuel pipe []. A controller [] receives the flow information from each of the flow meters [], to evaluate performance of the combustion system []. Controller [] also providing control information for controlling the flow of secondary air dampers [] into the combustion system [], and optionally controlling the flow of fuel in each fuel pipe [

A system for sealing a port of a pulverizer. A pulverizer has journal assembly and a port for receiving the journal assembly. At least a portion of the journal assembly extends through the port. The system further includes a seal having a first end and a second end. The seal includes a first opening at or near the first end and a second opening at or near the second end. A bore extends between the first opening and the second opening. One of the first end and the second end is coupled to the pulverizer and the other one of the first end and the second end is coupled to the journal assembly. The seal inhibits fluid communication through the port.

A wear plate for mounting in a wear protecting disposition on a rotor disc of a pulverizer includes a body portion having a radially outer circumferential edge and a radially inner circumferential edge , an abutment shoulder along the one angular edge of the wear plate , an underlap flange on the one angular edge of the body portion , and an overlap rim on the other angular edge of the body portion. The underlap flange is cooperatively configured with respect to an overlap rim of a respective adjacent wear plate that is in interengagement with the wear plate such that the overlap rim of the respective adjacent wear plate at least partially overlaps the underlap flange of the wear plate.
