Low NOx conditioner system for a microturbine power generating system
First Claim
Patent Images
1. A microturbine power generating system for producing power, comprising:
- a turbine for converting gaseous heat energy into mechanical energy;
a power converter for converting the mechanical energy produced by the turbine into electrical energy;
a combustor for producing gaseous heat energy by igniting an air and fuel mixture;
a fuel supply for supplying fuel to the combustor;
a compressor for compressing intake air and supplying the compressed air to the combustor;
the turbine receiving the heat energy from the combustor;
a recuperator disposed between the compressor and the combustor;
a single shaft coupling the turbine, compressor and power converter to allow the power converter to rotate in unison with the turbine and to thereby use the mechanical energy extracted by the turbine to power the compressor and produce power; and
a low NOx conditioner segment operably disposed between said compressor and the combustor the low NOx conditioner segment generating preheated compressed air, forming a heated air-fuel mixture with the preheated compressed air to a second temperature pre-oxidizing the mixture and supplying the mixture to the combustor during startup of the system.

Abstract
A microturbine power generation system includes an electrical generator, a turbine and a compressor intermediate the generator and the turbine. The turbine, compressor and electrical generator are secured together by a tieshaft. The tieshaft is prestressed such that faces of the turbine, electrical generator and compressor maintain contact during high-speed, high-temperature operation of the system.
