recently, but it’s rare to see one set goals such as PDL has set for itself. In total, 23,000 tonnes of exclusively local biomass, including raw wood, sawmill waste, bark and crushed pallets from within a radius of 150 km, will fuel the plant every year. At the same time, this investment will provide support to the timber industry, which is still under-developed in the Chablais region.


Construction took place in two distinct phases. The first consisted of deconstructing the former coal boiler, which had not been in service since 2000. Nevertheless, it was possible to preserve the building and this now houses the wood reserve and the new boiler itself. After spending almost a year taking it down, the company was then able tobegin construction of the boiler by assembling the modules that needed to be mounted. The project was finally

completed at the end of October, 2012.


It took several steps in order to bring the boiler into operation: the first two weeks of November, 2012, were spent connecting it to the steam piping and also obtaining the certification necessary to run it.


By mid-November, it was fired


up for the first time so that the interior building work could dry. The temperature was increased by 100 degrees every 24 hours over ten days in order to reach 900 degrees Celsius.


The boiler was officially started on 1 December, 2012 – the initial goal was to have it running at 50% capacity for several days


and then make any adjustments so that it could begin regular operation by early January. A whole set of tests were performed, including emergency shutdowns, in order to test all of the mechanical systems for automatic operation and safety. Since 7 January, the boiler has been running at optimum capacity. Tests, measurements and performance evaluations with the operator have made it possible to verify the installation and the match between the services it provides and the modes and methods that appear in the contract.


Today, the new biomass boiler at PDL has attained a constant level of performance and will make it possible, beginning this year, to reduce CO2 emissions from the plant by 11,500 tons per annum.

ten years after the new unit has been commissioned, all the biomass will be sourced locally. Jinwon Mok, CEO of Doosan Power Systems, said: “This major contract win for E.ON’s Provence


project is further confirmation of Doosan’s capability to undertake major plant conversion and construction projects, drawing on technical expertise and project management skills across


our turbine, boiler and after- build service businesses. It is also a valuable reference for Doosan in the biomass sector, following on from our 2012 contract wins for the conversion of the


Ironbridge power plant in the UK and the Atikokan Generation Station in Ontario, Canada”. More information from www.doosanpowersystems. com
