A Power boiler project calls for skilled engineers

Foster Wheeler’s Engineering know-how is an essential part of a boiler project. The boiler design is made in Varkaus and production is purchased globally either from own workshops or sub-suppliers.

Foster Wheeler’s internationally recognized project execution is based on international standards.

Example project: Supercritical OTU CFB in Lagisza, Poland, Provides Cost-Effective Energy While Reducing Emissions

Foster Wheeler AG ‘s world’s largest circulating fluidized-bed (CFB) steam generator – which is also the world’s first supercritical CFB -- has successfully started operating at the Lagisza power plant, owned by Polish utility company Poludniowy Koncern Energetyczny SA (PKE).

Foster Wheeler’s Global Power Group provided the turnkey supply of the boiler island, including engineering and design, erection, civil work, start-up, and commissioning. The new CFB replaces 1960s-era pulverized coal units at the power plant and was built adjacent to the old boilers. Many existing plant systems, including coal handling and water treatment, were renovated for use with the new CFB unit.

The Lagisza CFB produces 460 MWe of electricity at an efficiency level well above that of typical coal plants. The unit incorporates a number of advanced design features such as compact solid separators, INTREX™ super heaters, and low-temperature flue-gas heat recovery that captures valuable heat that would otherwise be lost.
The unit incorporates – for the first time ever in any CFB – highly efficient BENSON vertical-tube supercritical steam technology. BENSON vertical tube is a new steam technology that is more efficient and reliable than conventional supercritical technology prevalent in the market today.

This CFB represents a culmination of 30 years of design evolution for developing a reliable, fuel-flexible technology for utility scale electricity production. The BENSON vertical tube technology not only lowers the cost of power production but, more importantly, improves the environmental performance of the plant. Specifically, in relation to the older, de-commissioned boilers, the new CFB burns less fuel and produces significantly lower levels of carbon dioxide (CO2) and other emissions for each megawatt generated.
