Abstract: An ash transport system and method is provided that includes a transport line, four hoppers, and an airlock or hopper valve attached to each hopper. The ash transport system transports an ash mass from the airlock or hopper valve to the transport line if pressure in the transport line falls below a predefined pressure threshold assigned to the respective airlock or hopper valve. After a predefined period of time elapses, the ash transport system transports the ash mass from the airlock or hopper valve to the transport line if the pressure in the transport line falls below different respective predefined pressure thresholds. The airlocks and hopper valves simultaneously transport the ash masses to the transport line if, prior to the predefined period of time elapsing, the pressure in the transport line falls below each of the respective predefined pressure thresholds.

Abstract: A sootblower isolation wall box provided for sealing the wall box opening of a large scale boiler to provide sootblower lance tube access to the boiler. The wall box assembly includes a clamping seal assembly having radial sealing segments which are individually actuated. Applying fluid pressure to actuating cylinders causes the seal segments to be clamped against the outer circumference of the sootblower lance tube. During cleaning cycles, the segments are actuated to provide a radial clearance with the lance tube. Preferably, the clamping seal assembly is used in connection with another seal assembly which is relied upon to provide sealing during the cleaning steps. In a preferred embodiment, the additional seal assembly is in the form of a labyrinth-type seal assembly.
