System and method for producing hydrogen rich fuel

摘要

A system for providing hydrogen enriched fuel includes first and second gas turbines. The second gas turbine receives a portion of compressed working fluid from the first gas turbine and produces a reformed fuel, and a fuel skid provides fluid communication between a turbine in the second gas turbine and a combustor in the first gas turbine. A method for providing hydrogen enriched fuel includes diverting a portion of a first compressed working fluid from a first compressor to a second compressor and providing a second compressed working fluid from the second compressor. The method further includes mixing a fuel with the second compressed working fluid in a reformer to produce a reformed fuel, flowing the reformed fuel through a second turbine to cool the reformed fuel, and connecting the second turbine to the second compressor so that the second turbine drives the second compressor.

1. A system for providing hydrogen enriched fuel, comprising:
a. a low pressure compressor, wherein the low pressure compressor produces a first compressed working fluid; b. a combustor downstream of the low pressure compressor; c. a low pressure turbine downstream of the combustor; d. a high pressure compressor in fluid communication with the low pressure compressor, wherein the high pressure compressor receives a portion of the first compressed working fluid and produces a second compressed working fluid having a higher pressure than the first compressed working fluid; e. a reformer downstream of the high pressure compressor, wherein the reformer receives the second compressed working fluid and produces a reformed fuel; f. a high pressure turbine downstream of the reformer, wherein the high pressure turbine receives the reformed fuel and produces a cooled reformed fuel; g. a fuel skid in fluid communication with the high pressure turbine, a fuel supply, and the combustor, wherein the fuel skid connects the fuel supply to the combustor and to the reformer and provides a first flow path for the cooled reformed fuel from the high pressure turbine to the combustor and a second flow path from the fuel supply to the combustor and a third flow path from the fuel supply to the reformer, wherein the fuel skid mixes the cooled reformed fuel with fuel from the fuel supply, and wherein the fuel skid provides a flow path for the cooled reformed fuel from the high pressure turbine to a third gas turbine; h. a first shaft connecting the high pressure turbine to the high pressure compressor and providing a driving engagement between the high pressure turbine and the high pressure compressor; and i. a second shaft connecting the low pressure turbine to the low pressure compressor.
