摘要： A liner fabrication tool includes a handle engaged to a first cam support and a second cam support where each of the cam supports has forward edge. An axle extends between the first cam support and the second cam support. A gripper is rotatably engaged to the axle between the first cam support and the second cam support. The gripper includes a first wall, a second wall, and a base extending between the first wall and the second wall, the base has an opening where the opening is positioned between and proximate to the forward edges. The opening receives a pin of a liner and insulation system where rotation of the handle in a forward direction applies leverage against the first cam support and the second cam support to bind the pin in the opening and compress the liner and insulation system immediately prior to welding.

摘要： The boiler cleaning apparatus and method provides for cleaning the exterior surfaces of a heat exchanger. The apparatus and method include tools and steps, respectively, for temporarily spreading tubes and holding open the tubes to gain access to tube lanes. Once access to a lane is attained, a nozzle assembly having an outlet for blowing high velocity cleaning fluid is selected from a group of nozzle assemblies. The selected nozzle assembly will have an outlet for blowing fluid in a direction that effectively cleans the tubes adjacent the opened lane. After the tubes are cleaned the tool for holding the lane opened is removed and the process is repeated for another lane.

摘要： A heat transfer panel, or multiple panels, utilized to absorbed heat from the turbine exhaust gas as part of the Rankin cycle which simultaneously distributes the exhaust gas through the waste heat boiler. The panel varies the gas flow characteristics across a transverse and longitudinal plane, thereby eliminating the need for a separate flow distribution device.
