The following partial list, generated from the Fern Engineering project files, represents examples of our study services.
GAS TURBINE POWER AUGMENTATION STUDY.
Fern Engineering was awarded a Small Business Innovative Research contract by the U.S. Navy to investigate the feasibility of increasing the power output of the Navy's shipboard GE LM2500 gas turbines using direct inlet water spray and/or steam injection to the combustor.
Result: Simulations indicate that the output of an LM2500 could be increased by up to 40% using maximum augmentation. A prototype water spray system is now being designed for testing.
COGENERATION PLANT GAS TURBINE RETROFIT STUDY.
Fern Engineering conducted a study for a cogeneration plant owner that examined options for replacing an unreliable gas turbine with a different model.
The current gas turbine was part of a 10-year old combined cycle power plant that also supplied process heat used to dry crops.
It was important that any replacement gas turbine matched up well with the HRSG so that the steam turbine would remain fully loaded and the heat duty delivered to the crop dryers would not decline.
Result: Fern identified a unique retrofit option that improved plant heat rate and was $7 million less than buying the full gas turbine package from the OEM.
HEAT RATE AND POWER IMPROVEMENT DESIGN.
Fern Engineering designed and optimized a plant featuring a new GE MS5001N gas turbine, a new HRSG, and a modified steam turbine.
Fern also specified and managed the plant modifications, including foundations, HRSG installation, duct work, piping, dampers, and steam turbine modifications.
Result: User generates 29,730 kW at an LHV heat rate of 9160 Btu per kW-hr.
POWER ENHANCEMENT.
Fern Engineering has investigated a variety of technologies which can increase power, improve heat rate, and reduce emissions.
Studies included inlet cooling, inlet supercharging, water and steam injection, emulsion firing, firing temperature increases, turbine hardware modifications, active tip clearance control, and water wash.
Result: A compilation, quantification, and costing for implementing technologies that increase gas turbine power.
