<p>An ambient pressure gas turbine system is provided that is suitable for mid-range power plants (for example, 1-4 MW) while achieving low NOx emission levels. The system includes a combustor (14) that burns a hydrocarbon fuel in air or another working fluid at ambient pressure. A first heat exchanger (12) upstream of the combustor (14) heats the working fluid to the combustor inlet temperature. A turbine (18) downstream from the combustor (14) expands combustion gases received from the combustor. The combustion gases are directed to the first heat exchanger (12) for heat exchange with the working fluid and then to a compressor (22) operative to compress the combustion gases. A second heat exchanger (20) between the first heat exchanger (12) and the compressor (22) further cools the combustion gases to the compressor inlet temperature. The system may also be used with coal fuel and may reduce omission of CO2.</p> |
