ATOMIZING DUAL FUEL NOZZLE FOR A COMBUSTION TURBINE

摘要

The dual fuel nozzle assembly (70) comprises a swirl cap (82) that is adapted to securely mount with an independent atomizing cylinder (74). A nozzle tip (78) that is adapted to removably mount with a liquid fuel pipe (76) is provided. The independent liquid fuel pipe and nozzle tip are removably positioned within the receptacle of the independent atomizing air cylinder. An atomizing airflow passage (84) is defined between the air cylinder wall and the outer surface (106) of the liquid fuel pipe such that the airflow passage is in fluid communication with the atomizing air supply channel (86) defined by the liquid fuel pipe flange portion (108).
