Centrax is to supply the gas turbine generator set at the heart of a new energy centre at a major health campus in Scotland, where it will reduce the hospital’s emissions by nearly 20 per cent while cutting costs by some £2m ($3.2m) per year.

The combined heat and power centre, at Aberdeen Royal Infirmary’s Foresterhill site, will feature a natural gas fired Centrax generator set, powered by a Rolls-Royce 501-KB7 gas turbine, combined with a waste heat recovery boiler.

In addition there will be a biomass boiler fired by woodchips for renewable energy and three dual-fuel boilers running on gas and light oil. The Centrax package will produce 5.5 MW of electricity plus 12 tonnes of steam per hour.

“This energy centre will not only replace our high-maintenance boiler plant but will also provide a flexible system suitable for what is one of the largest single health campuses in Europe,” said Gary Mortimer, estates manager for National Health Service Grampian Estates.

“It will provide extra energy needed for current and future developments at Foresterhill and bring a 17 per cent reduction in present C02 emissions, equating to some 4500 tonnes per year. This partial shift away from fossil fuels also puts NHS Grampian in the best position to manage future energy cost fluctuations.”

The new centre will generate about 90 per cent of the Foresterhill site’s electricity.

This order for Centrax extends the company’s successful recent sales record in the UK healthcare sector, which is committed to reducing emissions. Major hospitals recently choosing Centrax gas turbine plants include Dundee (2.6 MW) and Leeds (4.8 MW). 


Westinghouse to provide emergency power supply 

Westinghouse has won a contract valued at €130m ($176m) to provide two new emergency power buildings with related emergency power systems for Axpo’s Beznau nuclear plant in Döttingen, Switzerland.

Beznau is a 730 MW two-unit nuclear plant equipped with Westinghouse pressurized water reactors. The contract includes engineering, procurement and construction of two buildings, in total four diesel generator sets with sub-systems, switch gears and transformers, HVAC systems, fire-protection systems, as well as all related digital safety and non-safety instrumentation and control systems.

Each diesel generator will provide emergency power in the range of 3 MW to one of the emergency power trains of Beznau units 1 and 2.

Emergency power connections for Beznau units 1 and 2 currently are provided by a hydroelectric plant located on the Beznau nuclear island and existing emergency diesel power units; however, the hydroelectric plant is scheduled to be dismantled in 2015. As a pre-condition, the new emergency power solution must be in place.

FG Wilson has redesigned its popular 26–200 kVA range of 23 models to give optimum performance, durability and serviceability to meet customers’ power requirements precisely. The range offers outstanding value for money and guarantees maximum efficiency and productivity as well as improved performance, durability and serviceability, say its makers.

This intelligent product redesign introduces a common-sense component arrangement to significantly increase the serviceability of the generators. The Open Set Range offers improved cable access and same-side positioning of frequently serviced items. A wide fuel fill neck on the base frame allows easy access and fill by the operator, avoiding spills.

The control panel tower is mounted on the side of the set and has a full-height door giving total access to all components and wiring. Drag points on the base frame ease transportation and reduce the risk of damage during forklift and other handling. A robustly constructed base frame, paint-coated using advanced processes, offers optimum corrosion resistance.
