Title: Innovations of Ahmed Abdelhafez in Gas Turbine Technology

Introduction

Ahmed Abdelhafez is a prominent inventor based in Dhahran, Saudi Arabia. He has made significant contributions to the field of gas turbine technology, holding a total of six patents. His work focuses on clean combustion systems that enhance efficiency and reduce emissions.

Latest Patents

One of his latest patents is a gas turbine combustion system with a controller. This innovative design features an integrated ITM micromixer burner shell and tube system for clean combustion. The system includes an oxy-fuel micromixer burner that separates oxygen from air within the burner, enabling oxy-combustion. This process results in an exhaust stream consisting of carbon monoxide (CO) and water vapor (H2O). The combustion chamber is designed to allow preheated air to enter a headend with an array of ion transfer membrane (ITM) tubes. These tubes separate oxygen from the preheated air and anchor flamelets on the shell side. The combustion products from the oxy-fuel flamelets expand through a turbine for power generation, after which water vapor is separated from carbon monoxide by condensation. A portion of the effluent carbon monoxide is compressed back into the burner system, while the remainder is captured for sequestration or utilization.

Another notable patent is a method for using an ion transfer membrane micromixer head end for power generation. This design also incorporates an integrated ITM micromixer burner shell and tube system for clean combustion in gas turbines. The process mirrors the previous patent, focusing on the separation of oxygen from air and the efficient generation of power through the combustion of oxy-fuel flamelets.
