Title:
METHOD AND APPARATUS FOR OPERATING A GAS TURBINE USING WET COMBUSTION
Document Type and Number:
WIPO Patent Application WO/2017/084656
Kind Code:
A3
Abstract:
The aim of the invention is to significantly increase the electrical efficiency or the proportion of the effective work of gas turbines, even in small gas turbines or microsize gas turbines having a simple design. According to the invention, the drawbacks of the prior art are overcome using wet combustion with oxygen, the oxygen being supplied via mixed-conducting ceramic membranes. The driving force needed for the oxygen to penetrate is created by lowering the partial pressure of the oxygen on the permeate side of the membrane module (5), and the energy required therefor is taken from the process energy produced in the gas turbine process.
