Abstract:
1. A fuel delivery system, comprising: a turbine operable at a range of loads from a start-up load to a full load; a primary manifold for supplying a fuel composition to the turbine, the fuel composition comprising a low energy gas, a high energy gas, or a blend of the low energy gas and the high energy gas; a secondary manifold for supplying the low energy gas to the turbine; a low energy gas delivery system comprising a low energy gas inlet, a gas split for feeding a first portion of the low energy gas to the primary manifold and feeding a second portion of the low energy gas to the secondary manifold, a low energy gas primary manifold outlet coupled to the primary manifold, and a low energy gas secondary manifold outlet coupled to the secondary manifold; and a high energy gas delivery system comprising a high energy gas inlet and a high energy gas primary manifold outlet coupled to the primary manifold, wherein the fuel delivery system is configured to allow the high energy gas to be delivered only to the primary manifold.
