Abstract
A positive displacement pump supplies a low lubricity liquid fuel through a main supply line to the combustors of a turbine. A pressure transducer and a flow meter are provided in the main fuel supply line. The fuel is supplied to a pressure compensated fuel delivery valve which divides the fuel equally among the combustors and affords pressure compensation. A controller is responsive to the pressure in the main fuel supply line to control a bypass pressure valve to supply fuel in the main supply line at a predetermined pressure. The controller also controls the total volume of fuel flow rate through the pressure compensated fuel delivery valve responsive to the flow meter. In another form, a centrifugal pump supplies fuel to the pressure compensated fuel delivery valve. A controller responsive to the flow meter in the main supply line controls the total fuel flow rate to the valve which divides the fuel equally among the combustors at equal flow rates.
