METHODS AND APPARATUS FOR CO-FIRING FUEL

摘要

A method of co-firing fuel within a gas turbine engine (5). The method may include injecting a first fuel (80) into a combustion system (20) of a gas turbine engine. The first fuel may include a high energy liquid fuel. The method may also include injecting a second fuel (90) into the combustion system. The second fuel may include a gaseous low Wobbe fuel. Only the first fuel may be injected during a first mode of operation. The first fuel and the second fuel may be injected simultaneously and discretely during a second mode of operation.
