COMBUSTOR MIXING ASSEMBLY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18450633 titled 'COMBUSTOR MIXING ASSEMBLY

Simplified Explanation

The patent application describes a mixing assembly that includes a pilot mixer and a main mixer. The main mixer consists of a main housing, a fuel manifold, a mixer foot, and a main swirler body with vanes. The main swirler body surrounds the main housing and creates an annular mixing channel. An annular main fuel ring extends into the mixing channel from the mixer foot. Fuel injection ports are positioned in either the mixer foot or the main fuel ring to discharge fuel into the central portion of the mixing channel.

  • The mixing assembly includes a pilot mixer and a main mixer.
  • The main mixer consists of a main housing, a fuel manifold, a mixer foot, and a main swirler body with vanes.
  • The main swirler body surrounds the main housing and creates an annular mixing channel.
  • An annular main fuel ring extends into the mixing channel from the mixer foot.
  • Fuel injection ports are positioned in either the mixer foot or the main fuel ring to discharge fuel into the central portion of the mixing channel.

Potential Applications

  • This mixing assembly can be used in various combustion systems, such as gas turbines, jet engines, and industrial burners.
  • It can improve the efficiency and performance of these systems by ensuring proper fuel-air mixing.

Problems Solved

  • The mixing assembly solves the problem of inefficient fuel-air mixing, which can lead to incomplete combustion and reduced performance.
  • It addresses the challenge of achieving uniform fuel distribution in the mixing channel.

Benefits

  • The mixing assembly improves fuel-air mixing, resulting in more efficient combustion and reduced emissions.
  • It enhances the performance and reliability of combustion systems by ensuring proper fuel distribution.
  • The design of the mixing assembly allows for easy installation and maintenance.


Original Abstract Submitted

A mixing assembly includes a pilot mixer and a main mixer. The main mixer includes a main housing, a fuel manifold positioned between a pilot housing and the main housing, a mixer foot extending outward from a forward end of the main housing, and a main swirler body including a plurality of vanes. The main swirler body surrounds the main housing and defines an annular mixing channel between the main housing and the main swirler body, and being coupled to the mixer foot. An annular main fuel ring extends axially aft from the mixer foot into the annular mixing channel. The mixer foot extends farther from the main housing than the main fuel ring. At least one of the mixer foot or the main fuel ring includes a plurality of fuel injection ports positioned to discharge fuel into a central portion of the annular mixing channel.
