Abstract
A solid fuel nozzle tip (201) having at least first (205) and second (207) ceramic shells is provided by the present invention. An inlet end of the first ceramic shell (205) is interconnected to a pulverized solid fuel nozzle (34), and an outlet end (301) of the first ceramic shell (205) is interconnected to an inlet end (305) of the second ceramic shell (207).
Claims17
A solid fuel nozzle tip, comprising:
- a first ceramic shell having an inlet end adapted to interconnect to a solid fuel nozzle and receive a flow of solid fuel from the interconnected solid fuel nozzle, an outlet end distanced from the inlet end, and a chamber having a peripheral wall defining a first passageway for directing the received flow of solid fuel from the inlet end to the outlet end of the first ceramic shell;
- and
- a second ceramic shell having an inlet end adapted to interconnect to the outlet end of the first ceramic shell and receive the flow of solid fuel from the interconnected outlet end of the first ceramic shell, an outlet end distanced from the inlet end of the second ceramic shell and a chamber having a peripheral wall defining a second passageway for directing the received flow of solid fuel from the inlet end to the outlet end of the second ceramic shell.
A solid fuel nozzle tip for use in cooperative association with a pulverized solid fuel nozzle of a firing system of a pulverized solid fuel-fired furnace, comprising:
- a first ceramic shell having an inlet end interconnected to the pulverized solid fuel nozzle so as to receive a flow of solid fuel from the nozzle, an outlet end distanced from the inlet end, and a chamber having a peripheral wall defining a first passageway for directing the received flow of solid fuel from the inlet end to the outlet end of the first ceramic shell;
- a second ceramic shell having an inlet end interconnected to the outlet end of the first ceramic shell so as to receive the flow of solid fuel from the first ceramic shell, an outlet end distanced from the inlet end of the second ceramic shell, and a chamber having a peripheral wall defining a second passageway for directing the received flow of solid fuel from the inlet end to the outlet end of the second ceramic shell;
- and
- a third ceramic shell having, an inlet end interconnected to the outlet end of the second ceramic shell so as to receive the flow of solid fuel from the second ceramic shell, an outlet end distanced from the inlet end of the third ceramic shell and a chamber having a peripheral wall defining a third passageway for directing the received flow of solid fuel from the inlet end to the outlet end of the third ceramic shell.
