SPX Flow CombiTherm Plus[/caption]
SPX Flow’s CombiTherm Plus pump provides safe and reliable transfer of hot fluids without the need for additional, external cooling systems. It is available in two configurations suitable for the pumping of hot oil or hot water. The pump keeps fluid temperatures uniform to ensure processes are predictable while its design protects seal faces and bearings from the heat of the fluid. Optimized cooling fans and large fins keep the temperature around the shaft sealing below 220°F even at high process temperatures up to 660°F. The heavy duty centrifugal pump is centerline mounted which allows thermal expansion without affecting shaft alignment. The combination of low temperature and alignment protects seals and bearings. The pumps are designed to handle high pressure throughout their flow range with hot oil pumps operating up to 360 psi and hot water pumps up to 450 psi.
New Voith gear
Voith Turbo unveiled VoreconNX, the next generation of its variable speed planetary gear. It is said to offer speed control with reliability and low life cycle costs for the oil & gas sector. The NX series operates in a low power range up to 10 MW. The Vorecon can be used in upstream, mid-stream and downstream applications. Depending on the speed required, power is fed back to the driveline by way of the planetary gear on the driven side. Adjustable pump blades in the torque converter provide stepless and wear-free control. A helical gear on the output side adapts the output speed to the compressor. It also has an integrated control and lubrication oil system.
Solving electrostatic discharge
Today’s environmentally-friendly hydraulic fluids and lubrication oils are produced with additive packages that contain no toxins or carcinogens, are free of heavy metals, and are ashless (produce no residue as a result of combustion). However, they solve one problem, but create others. A lack of metal content results in low electrical conductivity which can lead to electrostatic discharge (ESD) within the system. ESD may result in arcing in the reservoir, damage to costly hydraulic components (valves, filters, cooler fans, electronics) or the formation of oil-aging deposits.
Take the case of a gas turbine lubrication system at a power plant. Plant personnel observed a crackling noise emanating from the lube oil filter housing, which was most evident during startup or cold start conditions. It would then fade away as the temperature increased. An inspection revealed burn marks on the surface of the filter housing. Discoloration and erosion of the housing surface caused by extreme ESD arcing was evident. Hydac Stat-Free filter elements were introduced. This led to no further audible evidence of ESD discharge, as well as no residual voltage in the oil flow directly downstream of the filter elements.
HYDAC’s Stat-Free filter element series combats ESD with a design that includes conductive components and with media combinations that minimize the charge generation of the filter and the oil. This technology has been designed and tested for gas and steam turbine applications.

GE Power has unveiled the Digital Power Plant for Steam, a suite of technologies that reduces greenhouse gas emissions by improving the performance and efficiency of coal-fired steam plants. By monitoring and analyzing data from more than 10,000 sensor inputs across the plant, the software is said to reduce CO2 emissions by 3%, maintain fuel quality, and reduce fuel consumption by 67,000 tons of coal per year with the same MW of output based on a 1,000 MW power plant. Operating on the GE Predix platform, the software suite includes: asset performance management to monitor equipment health; operations optimization for plant and fleet-wide; boiler optimization, a coal analyser for tuning combustion and exhaust management processes, a digital twin of the physical steam plant that is continuously monitored to identify gaps between actual and ideal performance relative to key performance indicators such as output or emissions; smart start; and business optimization (aggregates information such as fuel and power price, demand, and plant capacity to enable energy traders to make better buying and selling decisions).
A2A Group, for example, has installed GE digitization software at its Chivasso power plant in Northern Italy to make it more competitive in the ancillary service market. GE upgraded one Ansaldo steam turbine and two 9FA gas turbines with its Dry Low NOx 2.6 + combustion system, as well as providing a new boiler system through its legacy Alstom business.

With FlexSILon TMC, HIMA offers a new approach to turbomachinery control. It includes operation, control and overspeed protection in a single safety system. It comes with standardized function blocks for operation (start-up, operation, manual functions), control (speed control, steam distribution, anti-surge) and protection, (bearing, temperature, pressure), and the ability to implement overspeed protection. This is an alternative to dedicated components from different manufacturers, which call for increased engineering and wiring effort, require more space in the control cabinet and necessitate the retention of a large inventory of spare parts. HIMax and HIMatrix safety systems, as well as the SILworX configuration, programming and diagnostics tool are the core of FlexSILon TMC. This core is supplemented with solutions for local visualization of on-site operation and sequence-of-event recording.

Petro-Canada Lubricants launched Turboflo Low Varnish (LV), a turbine fluid that resists varnish and sludge build-up. By minimizing harmful accumulation, it is said to optimize equipment performance and reliability, while also preventing downtime for removal. GTs have a common turbine and hydraulic reservoir, operate at extremely high temperatures with intermittent starts and stops, which can accelerate oxidation. This is the leading cause of varnish formation and deposition, and thermal degradation of the turbine fluid. Turboflo LV helps improve fluid and equipment performance. After six years of field testing in two GE Frame 7 FA units with peaking service, the Turboflo LV prototype fluid is said to remain in excellent condition and resisting excessive degradation with little or no varnish deposition.
