Multi-combustor turbine

摘要

A system for the gradual oxidation of fuel is disclosed. The system includes an oxidizer that has a reaction chamber with an inlet and an outlet. The reaction chamber is configured to receive a fluid comprising an oxidizable fuel through the inlet. The oxidizer is configured to maintain a flameless oxidation process. The system also includes a heating chamber with an inlet and an outlet. The inlet of the heating chamber is in fluid communication with the outlet of the reaction chamber. The heating chamber is configured to receive the fluid from the reaction chamber and selectably heat the fluid.

1. A system for gradually oxidizing fuel, comprising:
an oxidizer having a reaction chamber with an inlet and an outlet, the reaction chamber configured to receive a gas comprising an oxidizable fuel through the inlet, the oxidizer configured to maintain a flameless oxidation process; a first heating chamber with an inlet and an outlet, the inlet of the first heating chamber in fluid communication with the outlet of the reaction chamber, the first heating chamber configured to receive the gas from the reaction chamber and to heat the gas; a turbine having an inlet and an outlet, the inlet of the turbine coupled to the outlet of the first heating chamber and configured to receive the gas from the first heating chamber; a compressor coupled to the inlet of the reaction chamber to compress the gas prior to the gas being received by the reaction chamber; a second heating chamber coupled between the compressor and the inlet of the reaction chamber, the second heating chamber being configured to receive the compressed gas from the compressor and to heat the gas prior to the gas being received by the reaction chamber; and a heat exchanger having a first portion coupled between the compressor and the second heating chamber such that the gas from the compressor passes through the first portion before the gas is received by the second heating chamber, and a second portion coupled to the outlet of the turbine such that the gas from the turbine passes through the second portion, the heat exchanger configured to thermally couple the gas in the second portion to the gas in the first portion.
