Reforming fuel-rich premixed low emissions combustor and related methods

摘要

PROBLEM TO BE SOLVED: To provide a combustion system for generating low-emission and more efficient hydrocarbon fuel as a supplementary feed to a gas turbine combustor, using heat integration.;SOLUTION: A reformer 60 for a gas turbine engine which processes supplementary fuel feed to the combustor includes a reformer core 62 that contains a catalyst composition 65, and an inlet flow channel for a reformer fuel mixture gas, air, and steam. An outlet flow channel 66 transports a reformed oil stream to the external of the reformer core to combine with a main combustor feed later, the reformed oil stream containing modified and thermally decomposed hydrocarbon and a large amount of hydrogen. Additional heat is transmitted to a first and/or second supplementary gas turbine fuel stream using one or more heat exchange units 72 and 77, because catalytic partial oxidation in the reformer is accompanied with high generation, and the fuel stream is thermally decomposed and evaporated before combined with the reformational oil. The combined hydrogen enrichment feed significantly improves the combustor performance.;COPYRIGHT: (C)2012,JPO&INPIT
