Keppel Seghers has secured a $35 million (€17.3 million) contract for the engineering, procurement, fabrication, testing and commissioning of Keppel Seghers’ proprietary BOILER PRISM technology, and a steam boiler for the expansion of an existing waste-to-energy (WtE) plant in Moerdijk, southwest of the Netherlands owned and operated by Afvalverbranding Zuid-Nederland NV (AZN).

The Moerdijk plant is the third largest plant in the Netherlands with a capacity to treat 660,000 tonnes of solid waste a year.

The state-of-the-art secondary air BOILER PRISM technology raises the overall energy efficiency of the plant. It will optimise air flow and mixing of flue gas as well as improve the combustion and heat conversion efficiency of the WtE plant. The proven BOILER PRISM technology will increase the effective throughput of the plant, reduce unscheduled stops and lower maintenance cost. It will also avoid the severe corrosion problems that many existing WtE plants are dealing with, extending the useful life of such plants.

Said Mr Marc Van Craen, Business Manager (Waste-to-Energy) of Keppel Seghers, “This repeat order from AZN is a vote of confidence from our valued customer for the superiority and reliability of Keppel Seghers’ technologies.

“Europe has a large number of waste-to-energy plants, many of which have been in operation for some years and are now facing problems as the waste that they are treating has considerably higher heat value than they were designed to handle originally. The BOILER PRISM offers owners and operators of such plants a cost-effective solution to deal with these problems, thus extending the plant life, increasing plant throughput and lowering maintenance cost” Mr Van Craen continued.

Keppel Seghers has previously delivered BOILER PRISMs to the first three production lines of the Moerdijk plant, and performed retrofit works on the existing grates and flue gas cleaning system. The BOILER PRISMs increased the availability of each production line by 500 hours a year, corrosion of the boiler was decreased by a factor of 10 to 0.05mm per 1000 hours in the critical zones. In addition, the interval between manual cleaning of the boiler was extended by 50%, while the overall maintenance costs were reduced by 14%.

One key benefit of the BOILER PRISM technology is that it can be retrofitted into most incineration plants, regardless of the supplier of the original incinerator design. Keppel Seghers has been supplying BOILER PRISMs to plants which use both Keppel Seghers designs as well as other supplier’s incinerator designs.

KIE orderbook exceeds $2 billion (€1 billion)
Keppel Seghers is actively pursuing over a billion dollars in new contracts even as it clinches the Moerdjik contract, which will bring its current order book to over $2 billion (€1 billion), including the $1.7 billion (€0.8 billion) solid waste management facility in Qatar secured in October 2006.

Keppel Seghers’ waste-to-energy technology is very well established in China and Europe. In China, Keppel Seghers is the undisputed market leader for imported waste-to-energy equipment with more than 60% of the market share.

In Singapore, Keppel Seghers has commenced the construction of Singapore’s newest waste-to-energy plant at Tuas South on 5 October 2006. This is Singapore’s first incineration plant to be built under the Public-Private Partnership (PPP) initiative.
