PROCESS TO PREPARE A HEATED GAS AND GENERATE ELECTRICITY

摘要

The invention is directed to a process to prepare a heated gas and generate electricity using an apparatus for expanding a compressed combustion gas comprising a combustor, a turbine rotor, a diffusor a compressor and a generator at a pressure ratio between 2 and 5. The combustor is comprised of an axially extending space around an axially extending combustor axis provided with one or more burners at one end and an circular slit as discharge opening at its opposite downstream end. The diffusor is comprised of a circular inlet opening fluidly connected to the discharge outlet of the turbine rotor, a flow path for combustion gas which extends axially away from the combustor and extends radially outward towards an circular outlet. The circular outlet is fluidly connected along its circumference to a receiving space.
