The U.S. Energy Information Administration released their Annual Energy Outlook in December which forecasts that by 2035, 83% of new capacity additions will be from either natural gas or renewable energy.
The forecast provides a strong correlation to government and public sentiment on energy.
The unpredictable nature of renewable power generation in select cases requires backup generation support from aero derivative turbines or other smaller scale industrial turbines. How these two fuel sources coexist remains a work in progress. Aero turbines have gas as their primary fuel system and the option of liquid fuel for backup. Of course, these systems can also be used for traditional generation such as peak generation.
A large manufacturer of aero derivative turbines recently chose Colfax America’s CIG pump line for their fuel injection pumps. A fuel injection pump delivers fuel directly to the gas turbine for combustion. The CIG pump is a Crescent Internal Gear pump with multiple stages good for applications with high pressure (4000 psi or 275 bar) or moderate pressure/low viscosity applications. It provides a user with smooth pulsation free flow, a vital feature for today’s engine requirements.
The chart to the right is a sample flow/pressure curve for the CIG pump, you will note that with a viscosity of 4.1cst, the flow output has less than a 15% change in flow over the pressure range 25psid – 1,600psid.
