Abstract:
A method and apparatus for vaporizing liquid fuel. The apparatus includes at least one capillary flow passage (12), the at least one capillary flow passage having an inlet end and an outlet end; a fluid control valve (18) for placing the inlet end of the at least one capillary flow passage (12) in fluid communication with the liquid fuel source and introducing the liquid fuel in a substantially liquid state; a heat source (20) arranged along the at least one capillary flow passage (12), the heat source operable to heat the liquid fuel in the at least one capillary flow passage to a level sufficient to change at least a portion thereof from the liquid state to a vapor state and deliver a stream of substantially vaporized fuel from the outlet end of the at least one capillary flow passage; and means for cleaning deposits (18, 20, 26) formed during operation of the apparatus. The flow passage can be a capillary tube heated by a resistance heater or a section of a tube heated by passing electrical energy therethrough. The liquid fuel can be supplied to the flow passage at any desired pressure depending on the required mass flow rate for the application. The vaporized fuel can be mixed with air to form an aerosol having a mean droplet size of 25 µpm or less to minimize ignition energy of the fuel-air mixture, promote fuel flow in an air stream, and combust the liquid fuel efficiently and cleanly.

Abstract:
A burner inlet assembly (200) and a method are disclosed. The burner inlet assembly (200) is for generating a fluid pulse deliverable to assist in removal of residues in a burner and comprises: a fluid accumulator (16) chargeable with a pulse fluid from a fluid source (30) at a charging flow rate; and an actuator (18) operable, in response to a change in an actuation signal, to discharge pulse fluid from the fluid accumulator (16) through an outlet conduit at a discharging flow rate, which is greater than the charging flow rate, to generate the fluid pulse. By providing a fluid accumulator (16), an existing fluid source (30) may be reused. By storing the fluid in the fluid accumulator (16), it is possible to generate the required fluid pulses to reduce or remove accumulated deposits or residues without affecting the performance of the fluid source (30) or the performance of any other parts of the processing tools. Storing the fluid is in the fluid accumulator (16) enables the fluid to be released from the fluid accumulator (16) through an outlet at a velocity or volume which is greater than that would be possible if the pulse was generated directly from the fluid source (30) itself. Accordingly, this arrangement enables a more effective fluid pulse to be generated which is better at removing residues or deposits than would be possible from a fluid pulse generated directly from the fluid source (30).
