Gas Turbine Air Controls

 

 

Air control is becoming more and more necessary to meet the emission requirements for operational GTs. It improves the starting reliability and load flexibility of gas turbines. The tighter demands of necessary emission control call for highly accurate and responsive air control VGV or VIGV control is vital, with OEMs adding multiple independent drives. Air bleed for compressor control and anti icing is vital.

In the last ten years HEINZMANN has supplied hundreds of electric guide vane servo systems to a gas turbine OEM in Europe for machines from 4 through 20 MW shaft power. HEINZMANN now offers electric bleed air control valves for the same range of turbines based on its high-performance electric actuation technology.

Gas Turbine Fuel Controls

 

 

HEINZMANN UK has supplied many hundred fuel control products to gas turbine OEM's and operators since 1993. Machines ranging from the smallest to over 100 MW. These may be supplied as component parts or as complete fuel systems. Gas or liquid systems for Legacy and younger engines, dual-fuel, DLE fuel systems may be supplied.

HEINZMANN fuel controls are based on electric motor, digital electronic and safety technologies and experience developed in the HEINZMANN Group since the 1980's and products feature many innovations not found in competitor products. These features deliver ease and flexibility of application, quality of control and reliability for customers.

Gas Fuel Systems

 

 

HEINZMANN UK can build fuel systems to suit any size or make of gas turbine; single or multi-stream as required for low NOx combustion systems, liquid fuel metering. All systems can be combined on one skid with purge if required.

• Upgrading the original fuel controls with replacement systems built into the space occupied by the original system
• Replacement of original hydraulically actuated fuel assemblies with electrically actuated systems designed one replacement of the original system
• No limits on size we build fuel system frames for all types of turbines.

Ignition

PROMETHEUS is an igniter power system for gas turbines. Used in conjunction with standard surface effect spark plugs it produces an intense spark twice a second while energised from a nominal 24 VDC battery power supply.
Energy conversion and utilisation in the spark plug is very high and compared with alternative systems. The spark projects further out from the tip of the plug providing more successful ignition considering air fuel ratio and pressure. This is especially true on liquid fuelled turbines with pressure atomised burner nozzles.
