Abstract
A dual fuel nozzle for a combustion turbine having a swirl cap that is adapted to securely mount with an atomizing cylinder proximate its discharge end. A nozzle tip that is adapted to removably mount with a liquid fuel pipe is provided. The atomizing cylinder comprises an outer wall having an inlet end and opposing discharge end, and flange portion formed proximate the inlet end. The flange portion is adapted to be securely coupled with the liquid fuel pipe to the combustion turbine. The outer wall and flange portion define a receptacle that extends from the inlet end and substantially downstream to the discharge end. The receptacle is adapted to removably receive the liquid fuel pipe and the nozzle tip. The liquid fuel pipe has an inlet end and discharge end with the discharge end adapted to removably receive the nozzle tip. The liquid fuel pipe defines a liquid fuel flow passage that extends from the inlet end and substantially downstream of the flange portion proximate the discharge end. The flange portion further defines an atomizing air supply channel. The liquid fuel pipe and nozzle tip are removably positioned within the receptacle of the atomizing air cylinder. An atomizing airflow passage is defined between the air cylinder and the liquid fuel pipe such that the airflow passage is in fluid communication with the atomizing air supply channel at one end and the swirl cap proximate the other end.
