Generator Set System Performance
The Generator Set is set up as a dual fuel system (liquid and gas) with water injection. The water injection system allows automatic changeover from gas to liquid without loss of load in event the fuel gas pressure begins to decay.
Using Bacton Natural gas (LHV= 49,940 kJ/kg) with water injection the maximum gas burn (at -10 C) under full load conditions will equate to 0.933 kg/sec. The O2 Levels in the exhaust gas will be in the range 15.5% to 15.7%.
Using Class A2 and Class D35 second gas oil (LHV= ?) with water injection the maximum gas burn (at -10 C) under full load conditions will equate to 1.042 kg/sec. The O2 Levels in the exhaust gas will be approximately 15.6%.
A high-speed single stage centrifugal pump inclusive filter instrumentation and control (bypass) provides the water injection to the gas turbine. The water injection system is rated to provide 0.57 kg/s of demin water with a maximum discharge pressure equaling 38 barg and maximum temperature equaling 60 C The water injection rate at the maximum gas burn (at -10 C) under full load conditions will equate to 0.363 kg/sec. For 35-second gas oil the water flow rate will equate to 0.454 kg/s.
The gas supply systems and water injection system are interlinked and controlled by an electronic gas turbine sequencer (Woodward Netcon 5000) which utilizes electrically/pneumatically operated flow control valves as follows:
· Liquid fuel flow control valve Woodward Model 1907 with a TM55P Actuator
· NOx water control valve Woodward Model 315 1A
· Gas Control Valve, Woodward Model 3103 with a TM55P Actuator
The combustion gases from the gas generator enter the power turbine at an approximate temperature of 1020 C and a pressure of 3.8 bar. The power turbine outlet conditions will be 490 C at a pressure varying from 120 to 300 mm of H2O (above atmosphere).
Generator Set Fire Protection & Gas Detection System
The Generator Set is also equipped with a fire protection & gas detection system. This consists of an automatic fire detection and extinguishing system based on CO2 flooding with both an initial and extended discharge for the auxiliary gas turbine and generator compartments. The combustible gas detection system has catalytic gas sensors located at strategic locations within the generator set.

Airflow:
Turbine Intake: 122735 m3/h
Turbine Compartment: 30100 m3/h, (2 fans 1 fan operating & 1 fan standby)
Generator Compartment: 16500 m3/h (generator rotor mounted fans)
Anti Icing System: For protection of the gas turbine inlet using hot ventilation air from the GT module. If icing conditions exist, the control will automatically command the 3-way valve to mix the right quantity of hot ventilation air with the gas turbine intake air.


2.)) Waste Heat Recovery Boiler
From the exit of the power turbine the combustion gases are ducted either
to the waste heat boiler or directly to the chimney via two interlinked
dampers. To accommodate a fluctuating process steam demand the bypass
can be operated from a fully opened to a fully closed position. The waste
heat boiler is designed to recover thermal energy contained within the
combustion gases and transfer this energy to process water converting it to
steam. The waste heat boiler has a nominal thermal capacity of between
24.5 and 26 MW. The waste heat recovery boiler is as follows:
Manufacturer Senior Thermal Engineering
Type Tube. Assisted circulated
Economizer, Generation and Drum
Drum pressure 10.50 bars
Boiler flow 30,000.00 kg/h max
The Waste Heat Recovery Boiler System Performance
The waste heat recovery boiler is designed to recover thermal energy contained
within the combustion gases and transfer this energy to process water
converting it to steam. The waste heat boiler has a nominal thermal capacity of
between 24.5 and 26 MW.
The boiler consists of two banks of tubes mounted vertically in the exhaust gas
flow. The lower of two banks is an economizer used to heat the incoming water
feed to saturation temperature at 10.5 bar. Water from the economizer is fed via
a small number of tubes to the boiler drum mounted on the top of the boiler
structure. The water from the drum has assisted circulation via a boiler
circulation pump to the top bank of tubes back into the top of the drum. From
here saturated steam is fed into the main process heat stream.
The temperature and pressure characteristics of the combustion gases and the
process water and steam entering and leaving the waste heat boiler are detailed
below:

4.)) Remote Control System
The gas generator set and auxiliary equipment are controlled and monitored from a remote control room by equipment provided in the gas turbine control system. The LM1600 gas turbine generator set control system uses microprocessors and digital logic circuitry to obtain the speed and autonomy of operation required.
Operating personnel issue commands to the gas turbine control system through switches and keypads provided on the control system panels. The control system registers and responds to critical malfunctions well before the operator is aware of them. The alarm printer permits the operators to observe the system operational status and functions.

The control room is comprised of a bank of control panels as follows:
· Diesel Generator control
· Vibration monitoring (Vibro-meter) and gas detection panel.
· Brush Alternator control panel.
· Generator protection panel.
· Gas Turbine Control Panel (Modicon PLC)
· LM1600 Woodward Netcon Control System
· Waste Heat Boiler Control
· Gas Compressor Vibration Monitoring
· GTG/GC fire alarm panel
· Black start fire alarm panel

Some of its key features are as follows:

Modicon PLC
The operator interface is the main operating module and contains a CRT with numeric displays showing data of the major sub systems and a keypad with soft switches which functions depend on the presented display.

Woodward Netcon 5000
The gas turbine control system is based on the Woodward Netcon 5000 system which is the central brain of the gas turbine control system. It contains the sequencing functions as well as the fuel control. The system receives input from sensors supplied as part of the turbine generator set as well from other panels.
The primary function of this controller is to maintain a constant power turbine speed of 7000 rpm from no load to full load conditions. This controller also performs the following functions:
· Matches generator output frequency to that of the active bus for automated synchronization.
· Controls the rate of acceleration and deceleration of the gas turbine
· Initiates, regulates, and terminates the flow of water injected into the gas turbine.
Vibration Monitoring System
Consists of a Vibrometer instrumentation rack complete with monitors. The monitors in the rack include power supplies and the necessary band pass and tracking filters to adjust the signals from transducers according to GE's recommendation for the gas turbine. Each monitor has a danger (alarm) and an alert (trip) level setting. Unfiltered transducer signals are available for investigating vibration problems (diagnosis). The following vibration & speed channels are monitored:
· GT Housing near the compressor rear frame vibration. (Accelerometer)
· GT turbine rear frame vibration. (Accelerometer)
· Power Turbine vibration (Accelerometer)
· HP compressor spool speed.
· LP compressor spool speed.
· Power turbine speed
· Gearbox vibration level (Accelerometer)
The generator vibration level is detected by 4 proximity probes (X-Y type arrangements). These probes are installed in pairs in both the drive end bearings and the non-drive end bearings.
