Ionpure contributes to Rijnmond success

Water pretreatment plays an important role in the power generation centre and the success of the Rijnmond Energy Centre in the Netherlands is due to its 1288 m3/h water pretreatment system and a 170 m3/h demineralization system.

Ionpure Technologies equipped the USFilter demineralization system with IP-LX continuous electrodeionization (CEDI) modules. Designed to produce high-purity water for boiler feed, the demineralization system includes two reverse osmosis systems feeding two CDI-LX systems with 25 modules per skid, each with a capacity of 85 m3/h.

The demineralization system treats brackish water from Rotterdam harbour. USFilter and Bechtel-Enka – the joint venture which constructed the new power plant – completed startup of the water treatment system in April, and performance has since been very good.

“Water quality from the RO/CDI system is exceptional, with conductivity averaging less than 0.07 µS/cm,” says Todd Hook, P. E., director of engineering and project management at USFilter. “In addition, the sodium concentration in the RO/CDI product water is about 1 part per billion and the silica concentration is below 3 parts per billion (ppb).”

The performance of the system significantly exceeds the water quality specifications, which require that the conductivity be less than 0.1 µS/cm and the sodium and silica concentrations be less than 10 ppb.

LK boosts reverse engineering

With the help of LK Limited, Qinetiq Power has enhanced the reverse engineering capabilities of its Gosport, UK, facility, enabling it to create CAD models of gas turbine generator blades.

Until recently, Qinetiq’s test centre in Gosport was a development facility for the design of ships’ hulls and propellers, and submarines and submersibles. The centre was equipped with an LK co-ordinate measuring machine (CMM) which was installed in 1992.

The gradual demise of shipbuilding in the UK coupled with the ability of modern simulation software meant that the amount of marine work passing through the site reduced dramatically a couple of years ago. That was when Qinetiq Power, headquartered in Farnborough, UK, took the opportunity to harness the underused CMM at Gosport for creating CAD models of gas turbine blades for reverse engineering.

Qinetiq sanctioned a £28 000 ($50 000) upgrade of the CMM, which was carried out on-site in just one week by LK in 2003. The old VAX computer with CMES software was replaced with a PC running LK’s Camio Studio DMIS-based on-line programming and measurement software, which allows more efficient data management. At the same time a new LK 2000 controller was fitted and the machine was rewired.

The most notable operational improvement following the upgrade has been the ability to digitally scan the surface of the blades at much higher speeds than was previously possible.

Pegasus Technologies and Ready Engineering sign coal alliance

Pegasus Technologies, Inc., a majority-owned subsidiary of Kennecott Energy Company, has entered into an alliance agreement with Ready Engineering Corporation to provide intelligent fuel management systems for coal fired power generation units.

Pegasus Technologies will market and license Ready’s coal blending and coal handling automation solutions (including Abacas and Coal Fusion) into the coal fired power generation industry in the US and other markets. The alliance offers operators of coal fired power generation units the capability to intelligently manage the fuel delivery systems, and optionally integrate with combustion optimization technology (Pegasus OS-2005 Optimization Suite). Power generating companies are now able to leverage their legacy coal handling hardware and control to their maximum potential.

Lee Ready, founder and president of Ready Engineering Corporation, said, “Our partnership with Pegasus brings a unique combination of optimization solutions to the power generation industry that will enable utilities to leverage more value from existing assets.”

Coal blending allows for the production of coal which is better tailored to the operational needs of individual power stations. The benefits of coal blending include: cost savings to power station operators through improved boiler performance and provision of fuel with better combustion properties; minimization of emission of harmful by-products such as NOx, SOx, ash and slag; and enhanced fuel flexibility.

Ready Engineering’s Automated Blending and Coal Analysis System (Abacas) is installed and successfully operating at a number of sites, delivering cost effective real-time coal blends based on plant operating requirements. Licensing and installation fees for automated coal blending range from $150 000-$300 000 depending on plant configuration.

Shell opens world-class centre

Companies that develop lubricants, fuels and additives will be able to benefit from world-class expertise, technical support and testing facilities at Shell’s new Marine and Power Innovation Centre in Hamburg, Germany. Opened in September, the new centre has already received long-term commitments from leading companies such as Infineum UK Ltd.

The facilities in Hamburg replace Shell Global Solutions’ existing centre in Amsterdam, and offer a range of low- and medium-speed diesel engines, from fully commercial multi-cylinder engines to single-cylinder research engines. These machines reproduce harsh working environments and help customers to predict the performance of the finished application. Customers will also be able to benefit from Shell Global Solutions’ expertise: “The centre’s scientists are experts in this field,” says Paul Snaith, vice president, Shell Global Solutions (UK). “The centre will serve a global market and will have the flexibility to accommodate future requirements within the marine and power sector.”

The centre includes offices, conference rooms, laboratories and other special test facilities. Substantial investment has been made on the facility, including a high-tech, 14-fuel vessel tank farm that will bring lubricants and fuels development closer together.

Scottish and Southern adopts CableSniffer as fault-finding standard

Scottish and Southern Energy customers in the UK can expect faster repairs and fewer holes in roads and pavements, as it becomes the first electricity company to adopt EA Technology’s revolutionary CableSniffer underground fault location equipment as standard.

The FTSE100 company has ordered nearly 200 CableSniffer kits for field engineering teams in its Southern Electric and Scottish Hydro-Electric regions. The equipment is also being trialled by every other network operator in Britain.

“The benefits of CableSniffer are clear – our extensive trials have confirmed that it pinpoints problems in underground low voltage cables much faster and more accurately than any other method,” said John Morea, Scottish and Southern Energy’s director of engineering.

“This means quicker restoration of service for our customers and far fewer holes in the road, with the added bonus of major cost savings. It’s a classic win-win solution for everyone concerned.”

CableSniffer works by recognising gases given off by insulating material when faults occur, in concentrations as low as 60 ppm. The operator uses a spike to make a series of test holes, 200 mm deep and 16 mm wide, and inserts the CableSniffer’s probe to check for fault gases. The rate at which readings rise or fall gives a highly accurate indication of the fault’s position: the higher the reading the nearer the fault. Each reading takes around two seconds.

EA Technology’s Colin Vickers said: “CableSniffer can normally locate fresh faults to within a metre, in under an hour, compared with several hours of hole excavations for cut and test methods.

“It typically costs £600 to £1000 ($1088-$1813) to dig each hole, so a CableSniffer unit can easily pay for itself in a single day. Operators who currently have to dig many holes each year to locate underground faults can make significant cost savings. CableSniffer has proved so sensitive that we can virtually guarantee ‘no reading, no fault’ on fresh faults, with a very good chance of locating older faults.”

EA Technology developed the CableSniffer with the assistance of the Strategic Technology Programme (STP) – an R&D programme funded by a consortium of electricity company members.

CableSniffer is available as a complete package, comprising a searcher bar for making test holes (a design used widely by the gas industry), gas detection unit with two spare heads and four spare filter papers, plus 100 tar plugs.
