Turbine = 18.500kg
Gearbox = 4100kg
Rotor = 4740kg
Alternator plus rotor = 15500kg
Turbine takes 52 ton of steam per hour to run on full 4.5MW

Steam Inlet Conditions: 52 barg Superheated Steam (380 degC – 420 degC)
Steam Outlet Conditions: 8 barg Superheated Steam (210 degC)
Shutdown April 2012 and barred over every 12 hours since.
The system runs off Natural Gas or low carbon diesel oil It is a back pressure system so 80 to 85 percent efficient unlike the CC systems which are around 45 percent.
All attached pipework goes with the unit apart from the HV system which is used in the systems left behind.
The system is approx 14mtrs long by approx 4mtrs wide and comes complete on a purpose built skid unit.
The unit was supplied on the skid unit so it can be transported with abnormal load conditions.
WHB2 (CHP2) is also a conventional Aalborg AX-4 water tube waste heat boiler producing superheated high pressure steam with a maximum rated output of 75 te/hr and an unfired output of approximately 14 te/hr.
WHB2 is similarly equipped with twin R & V in-duct register burners for supplementary firing. NOx levels from WHB2 are not an issue (due largely to the much lower NOx levels from GT2.
The much larger burner capacity (49 MW max heat input when supplementary firing, 60 MW on fresh air firing) means that the minimum firing capacity (4 MW on supplementary firing and 6 MW on fresh air firing) are correspondingly higher than for WHB1 and therefore even on minimum firing, will produce a significant quantity of steam.

WHB1 (CHP1) is a conventional water-tube waste heat boiler producing superheated steam at 43 barg and between 360 and 380 deg C, producing approximately 11 te/hr of steam when running on Turbine Exhaust Gas (TEG).
The boiler is equipped with two R&V model TTL/MG 12.5 in-duct register burners for supplementary firing. This is a design of burner routinely used by the boiler manufacturer (Aalborg) for this type of application. The R&V burner design is well tried and tested in this type of application and has a reference list of over 300 similar applications since 1976.
The in-duct register burner is commonly used across Europe in this type of application in preference to the grid type burner more commonly used in North America.
The waste heat boiler can be fully fresh-air fired if the gas turbine is not available.
Although WHB1 is rated at 45 te/hr, it is regarded as being incapable of operation at rates above about 35 te/hr due to flame lift off.
