摘要： A dual fuel burner system includes a fuel burner housing and a main fuel supply conduit within the fuel burner housing. A main fuel nozzle is positioned proximate to a downstream end of the fuel burner housing and is in fluid communication with the main fuel supply conduit. The main fuel supply conduit is configured to provide 100% of the heat input requirement of the dual fuel burner system. A secondary fuel supply conduit is within the fuel burner housing. The secondary fuel supply conduit is configured to provide 100% of the heat input requirement of the dual fuel burner system. An air circuit is in fluid communication with an outlet of the main fuel nozzle. A direct spark ignitor is positioned proximate to the outlet of the main fuel nozzle.

摘要： A solid fuel nozzle tip for issuing a flow of mixed solid fuel and air to a boiler includes a tip body having an inlet and an outlet defining a longitudinal axis therebetween. The tip body includes a slot on an inlet side of the tip body extending in a direction parallel to the longitudinal axis. The slot includes an opening facing the inlet side of the tip body and a recess formed at an angle with respect to the longitudinal axis to at least partially retain a pivot pin. A solid fuel nozzle assembly for issuing a flow of mixed solid fuel and air to a boiler includes a solid fuel nozzle tip with a tip body, as described above, and a locking plate operatively connected to the tip body to assist in retaining a pivot pin within the slot of the tip body.

摘要： An elbow for a solid particle conveyance system includes an elbow body having an inlet duct and an outlet duct with an interior space defined between the inlet and outlet ducts. An aeration insert is mounted to the elbow body for aerating solid particles passing through the interior space of the elbow body. The aeration insert is mounted to the elbow body to provide aeration from an elevation between that of the inlet duct and the outlet duct to facilitate downward movement of solid particles from the inlet duct across the aeration insert, and out through the outlet duct.

摘要： A heat exchange system includes a shell having an interior with an inlet and an outlet wherein a first fluid circuit is defined from the inlet, through a heat exchange volume within the interior of the shell, to the outlet. A tubesheet is mounted within the shell dividing between the heat exchange volume and a plenum of a second fluid circuit within the interior of the shell. A set of tubes extends through the heat exchange volume, a respective interior passage of each tube being in fluid communication with the plenum through a respective opening though the tubesheet. The second fluid circuit includes the plenum and interior passages of the tubes. A spray nozzle is mounted in the plenum of the second fluid circuit with a spray outlet directed toward the tubesheet for cleaning the tubesheet with a submerged impingement jet issued from the spray nozzle.

摘要： A solid particle distribution controller includes a plurality of division plates proximate a division between an upstream solid particle conveyance pipe and a plurality of downstream pipes. The solid particle distribution controller also includes a plurality of extension plates. Each of the extension plates is movably mounted proximate to a respective division plate for movement in an upstream and downstream direction with respect to the division plate. The plurality of extension plates are configured and adapted for motion in the upstream and downstream direction independent of one another to extend upstream of the division plates as needed to improve solid particle distribution among the downstream pipes.
