Problems solved by technology

However, the additional hardware necessary to control the inhibitor concentration and inject the inhibitor can increase the cost of the turbine engine to the point where the cost outweighs the possible benefit from such injection
Furthermore, in many known turbine engines, physical space constraints can limit access to transport and install such additional hardware, and limit the positioning of additional wall and casing penetrations

Abstract

The invention relates to an additive injection system for use with a turbine engine and a method of assembling same. Concretely, a method for assembling an additive injection system for use with a turbine engine includes coupling an atomizing air connection to a fuel nozzle assembly and coupling an additive source to the atomizing air connection.

Description

technical field [0001] Embodiments described herein relate generally to rotating machines, and more specifically, to turbine engine fuel nozzle assemblies. Background technique [0002] At least some known turbine engines ignite a fuel-air mixture in a combustor to produce combustion gases that are directed toward the turbine via a hot gas passage. Known combustor assemblies include fuel nozzles that direct fuel to a combustion zone of the combustor. The turbine converts the thermal energy of the combustion air stream into mechanical energy used to rotate the turbine shaft. The output of the turbine can be used to power machinery such as a generator, compressor or pump. [0003] In at least some known turbine engines, during operation, the combustion of fuel and air may introduce impurities into the combustion airflow that may adhere to portions of the combustor and portions of the turbine engine downstream of the combustion zone. Over time, such impurities can cause corr...
