Abstract
A turbine liquid fuel simulator exposes the components of a liquid fuel system in a turbine engine to the same fuel flows and pressures that the liquid fuel system would endure in an actual startup and run sequence, without burning or otherwise emitting the liquid fuel from the system. A fuel porting mechanism, such as a direction control valve, is installed in each combustor of the turbine engine. The fuel porting mechanism is movable from a first position, wherein liquid fuel is delivered to the combustor nozzle to be burned in normal operation, to a second position, wherein the liquid fuel is diverted to return lines that deliver the liquid fuel back to the fuel tank. To simulate the actual pressures and flows, pressure differential orifices can be installed in the return fuel lines. The orifices includes structures that modify the liquid fuel flow to mimic delivery to the nozzle.
