First UK SCR project will include Clyde Bergemann�s on-load cleaning technology

Scotland/UK, August 2010
Doosan Power Systems, UK, (formerly Doosan Babcock Energy) experts in steam generation technology for the global power market, awarded Clyde Bergemann Ltd, Scotland (CBS) the contract to deliver on-load cleaning systems (sootblowers) for two new economisers on 1 x 500 MW unit at E.ON�s Ratcliffe Power Plant in the UK. The systems to be installed include 20 PS-PB part retractable oscillating sootblowers and 4 PS-SB part retractable fully rotating sootblowers. The additional 3 x 500 MW units at the plant will be upgraded in subsequent years thereafter and will also be installed with Clyde Bergemann technology.

The plant is undergoing an environmental boiler upgrade known as the Ratcliffe Environmental Upgrade � REU, in order to ensure the plant meets legislative targets for reduced emissions, as agreed by the Large Combustion Plant Directive (LCPD). Part of the REU includes the installation of Selective Catalytic Reduction (SCR) technology to reduce NOx emissions. The SCR module includes a new economiser with the existing boiler back pass economiser also being replaced. Ratcliffe�s SCR technology will be the first of its kind in the UK with other plants expected to follow in order to meet the timeline of the LCPD.

The technology to be supplied by CBS is designed to eliminate the build up of ash deposits on the economisers which can lead to a reduction in heat transfer during the boiler feedwater pre-heating process leading to increased operating costs. The first set of blowers for boiler unit one are due to be delivered in June 2010 with the other three boiler units planned for each subsequent year thereafter.

CBS�s long standing relationship with Doosan Power Systems as well as the high level of technical support provided from the initial stages of the project helped secure the contract for CBS.

CBS Sales Manager, Iain Carruthers, comments: “This was a targeted contract for CBS and we look forward to working as a key technology partner with Doosan Power Systems on what is the first installation of its type in the UK�.
