Siemens has released an upgrade to its SGT-800 gas turbine. This provides an output of 53 MW and an electrical efficiency of 39% in simple cycle application. In a 2x1 combined cycle configuration, the power output is 150 MW at a net efficiency of more than 56%. Its dual fuel Dry Low Emission (DLE) systems keeps NOx levels below 15 ppm and CO emissions below 5ppm. This upgraded turbine will be offered in addition to the two current SGT-800 versions with power outputs of 47.5 and 50.5 MW. Contracts for the first six 53 MW units have been signed. They will be delivered in 2016.
The upgraded turbine is based on the full-scale engine validation testing and operational feedback from the 50.5 MW unit. The 53 MW rating has been achieved through: optimized and re-staggered first compressor stages which increase efficiency and mass flow; optimized cooling layout of turbine guide vanes; and adjusted clearances in turbine stage 1 and 2. Minor changes of the machining of four stationary components have been required to exploit the performance tuning potential in the turbine section. No changes have been made to castings or materials and the outlet temperature from the combustor remains the same. All improved components are retrofittable within the existing 50.5 MW series.
Siemens has launched a new release of its power plant control system. The SPPAT3000 R7.2 focuses on the humanmachine interface (HMI). New functions and simplified operations help control room personnel react reliably to critical situations. It will be part of all Siemens new control solutions and can be integrated or retrofitted to existing control systems. New features in the SPPA-T3000 R7.2 include shift management, condition monitoring of the power plant components and diagnostics tools, alarm displays, classification of messages and alarm indicators.
In addition, the Siemens SPPA-T3000 Cue is the latest release of its instrumentation and control system. Its optimized HMI helps personnel interact with the system efficiently. SPPA-T3000 Cue supplies contextbased and targeted information (cues).
Siemens has produced a steam turbine in the capacity range up to 10 MW that operates almost entirely without lubricants. The bearing systems consist of oil-free, air-cooled, electromagnetic bearings. The valve actuators operate with a minimum oil supply and are controlled via software-controlled electric motors. The trial run of the first turbine equipped with magnetic bearings was successfully completed in Vattenfall’s lignitefired Jänschwalde steam power plant, located in the southeast of the German state of Brandenburg, after which the model SST- 600 steam turbine was officially handed over. The turbine has been running in fullload operation since February 2015, at speeds of up to 5,700 rpm. It is used as a feedwater pump drive. www.siemens.com
The company has developed the Roots centrifugal compressor to boost the energy efficiency of industrial air and gas and wastewater applications. The design is said to be more efficient than turbo blowers and fans, and is said to improve energy efficiency by at least 5% for a mediumsize compressor/impeller. Compression energy accounts for up to 60% of entire plant operation costs because of its intensive energy use, making it an obvious target for efficiency savings. www.geoilandgas.com
Diesta heat exchanger technology for aircooled LNG plants has been developed by GEA Batignolles Technologies Thermiques, Wieland Thermal Solutions, and Technip. Diesta (Dual Internally and Externally Structured Tube for Air-coolers) is a combination of two established technologies for the outside and inside of a tube, the key component of an air-cooler. This technology is said to increase LNG production by 2 to 3%, while taking advantage of compression power savings. The footprint can be reduced 20%. www.gea-heatexchangers.com
As well as designing new cranes, Konecranes can renovate, retool and refit older cranes to help companies wring every last ounce of capability out of their equipment. The process replaces worn parts and adds more modern features such as controls to extend useful life, raise capacity and bring equipment into compliance with OSHA standards.
A typical modernization includes gearing, motors, drums, bearings, shafts, axles, brakes and controls. Modernization reduces the weight of older cranes, as new motors, trolleys, hoists and other components are lighter than original equipment. An engineering assessment evaluates the current condition and provides an estimate of its remaining design life and recommendations for next steps. www.konecranesusa.com
After a billion dollar investment plan, GE has manufactured its first 9HA gas turbine at its Belfort Gas Turbine Center of Excellence in France. It will be shipped to Bouchain, France, where Électricité de France (EDF) is developing a new plant. It is scheduled to enter commercial service in mid- to late- 2016 in the Nord Pas-de-Calais region.

Ametek Land has launched the 4650-PM Continuous Dust Monitor to help power plants meet the U.S. EPA’s new Mercury and Air Toxics Standards (MATS) for particulate matter measurement, which sets limits for coal and oil-fired generation. It is suitable for both PM-CEMS (PMContinuous Emission Monitoring) and PM-CPMS (PM - Continuous Parametric Monitoring System) in dry stacks where condensed water is not present. It has a minimum range of 0-15 mg/m3. www.landinst.com
Johnson Controls’ YCP-2020 is a containerized Gas Turbine Inlet Air Cooling (GTIAC) solution. The 8,000 kW system comprises York mechanical chillers, chilled and condenser water pumps, electrical starters and a Metasys control system. Its modular design minimizes site space requirements, and allows flexibility in layout. GTIAC is said to enhance power output by up to 30% and efficiency by up to 4 %. www.johnsoncontrols.com
Schneider Electric has introduced Foxboro pressure transmitter “S” series models IDP10S, IGP10S and IAP10S. These two-wire pressure transmitters feature FoxCal technology.
Designed for industries requiring differential, gauge and absolute pressure measurement, the S series eliminates inaccurate sensor selections. The instruments transmit a 4 to 20 mA signal with a superimposed HART smart instrumentation digital signal for remote configuration and monitoring. www.fielddevices.foxboro.com
Overspeed protection is an essential requirement to minimize the risk of failure in the pump speed governing system which can lead to rotor damage. The Sensonics Sentry G3 system has an independent digital signal processor (DSP) for each channel of measurement. It is typical for overspeed protection to use a two out of three (2oo3) channel arrangement to meet spurious trip requirements. This is implemented in G3 by using 3 modules, each with a single DSP channel to maintain channel hardware segregation, and configured with the overspeed algorithm. The rack based system operates on a dual +24V power supply. Response time is less than 20ms. www.sensonics.co.uk
FLIR Systems FLIR GF343 Optical Gas Imaging camera is being used for monitoring leak detection on hydrogen-cooled turbogenerators. Hydrogen-cooled generators are monitored for their hydrogen concentration for safe and efficient operation. Concentrations of hydrogen (4% to 75%) in air can be explosive. Typically, leak detection and repair (LDAR) of the generators is performed during a shutdown. By adding a small concentration of CO2 (< 5%) as a tracer gas, maintenance teams can monitor for leaks during full operation using a FLIR GF343 CO2 Optical Gas Imaging (OGI) camera. www.flir.com
Schneider Electric released its Tricon CX compact safety system for operational integrity, and protection against external threats such as cyberattacks. It is said to be smaller, faster, lighter and more powerful than previous safety systems. Form factor is reduced by 50% and weight by 67%. The performance boost is said to be five times. www.schneider-electric.com
Swift-JB International has announced a line of high pressure T-Type filter assemblies. They have a stainless steel construction and working pressures up to 20,000 psi (1,378 bar). They are intended for extreme environments such as those found in the offshore oil industry and power generation.
The FJV-3 Series high pressure filters use porous metal felt filter elements that employ filter media of thin filaments of non-woven stainless steel. Because it is up to 85% porous, metal felt media provides flow rates up to 20 times higher than those of other media. Random fiber filtration (metal felt) can provide absolute particle retention, longer on-stream time and high dirt-holding capacity for under 60 micron filter elements. www.swift-jbinternational.com
