Gas Fired Power Stations
Installation and Commissioning - Combined Cycle Gas Turbine
Installation and Commissioning of gas turbines, HRSG (Heat Recovery Steam Generators) and steam turbines.
Gas fired power stations are very much lower in carbon emissions because of efficiency and the amount of hydrogen rather than carbon in the fuel. They hydrogen burns to water in the exhaust rather than carbon dioxide.
The Combined Cycle referrs the gas turbine power cycle with the exhaust gasses providing heat for a steam power cycle involving the Heat Recovery Steam Generator and Steam Turbine.
This is the base load power station of choice in much of the world because of its refined and robust design providing efficiency, reliability and international support. Ratings from 100MW to 750MW.

Installation and Commissioning HRSG

Two HRSG
Installation and commissioning of Heat Recovery Steam Generators. For base load operation, available with modifications to suit start stop operation and to support variable demands of the grid. Supplementary firing into the inlet duct can be added to boost output or balance fuel usage.
Installation and Commissioning - Gas Turbines

GE Frame 9 GT
The GT Forms the basis of the power system. With it modular construction and integrated distributed control system rapid build programmes and sophisticated operation and controls are the norm. It is often arranged with bypass stacks to allow the GT's to run in simple cycle without the steam cycle thus increasing flexibility of operation.
Power Station Control Schemes
HMI for Gas Turbine
Loftus Technical Services are expert in the integration of controls for power stations. A Top level DCS (Distributed Control System) will overview the individual controls supplied by the main suppliers for Gas Turbines, Steam Turbines, HRSG and Balance of Plant. The contractor for the DCS and the suppliers of other key plant on the power statiion (water Treatment, Supplementary Firing, Desalination, dispatching, communications, protections and firefighting) all need integrating to the overall control scheme.
The information is presented to operative, engineering and managment by HMI (human machine Interface) screens as the one shown on the left for the Gas Turbine.

Balance of Plant HMI
The steam cycle is key area requiring integrating into the overall station contol system. The steam cycle operation largly defines the efficiency of the plant as there is much to develop during the design phase and optimise over the lifetime of the installation.
Several individual suppliers will have been involved in the putting together of the steam cycle components such as the HRSG, steam turbine, condenser, duct firing, feed pumps, feedwater dosing, vacuum pumps etc. The intergration of the design and control system and the mangement of these sub-suppliers during their supply and commissioning are key ares where Loftus Technical Services can add value to the project.
