The ACoPP project is addressing hard coal and lignite fired power plants with advanced steam conditions, advanced integrated waste heat utilization concepts and an integrated CO2 reduction technologies (post combustion andoxyfuel) aiming at near-zero emissions while operating at highest efficiency.
In order to tackle the above mentioned targets the project will exploit advanced technology concepts such as CaO looping, oxyfuel combustion and flue gas conditioning for CO2 capture.

Nadrzędnym celem projektu jest osiągnięcie technicznej gotowości do demonstracji w skali przemysłowej koncepcji bloku energetycznego ze spalaniem tlenowym zintegrowanego z układem sekwestracji CO2 (CCS). Partnerzy skupieni w ramach utworzonego Konsorcjum ocenią i zaproponują odpowiednią koncepcję wybraną z trzech analizowanych opcji spalania węgla: spalanie pyłu węglowego w kotle pyłowym (PC), spalanie węgla w cyrkulacyjnej warstwie fluidalnej (CFB), spalanie ciśnieniowe. Zamierzeniem jest również: wskazanie możliwości przystosowania obecnego systemu energetycznego, tak aby uzyskać system bardziej zrównoważony i oparty na zróżnicowanym zestawie źródeł energii (w tym źródeł odnawialnych); poprawa sprawności energetycznej; stawienie czoła naglącym zadaniom, jakie stawia bezpieczeństwo zaopatrzenia i zmiany klimatyczne; a jednocześnie potrzeba zwiększenia konkurencyjności polskiej gospodarki.

The purpose of the project is to develop and improve the modelling methods for biomass combustion and co-combustion in circulating fluidised bed (CFB) boilers. Such method are essential for reliable design and scale up of boilers, but are at present to a large extent lacking.
The properties of different biomass fuels are quite different from typical coal-type fuels and the properties of biomass fuels vary largely both with respect to moisture content and fuel size and shape of fuel particles, e.g. from fine sawdust to long strips of bark or to large chunks of waste wood. The flow properties affect the mixing of biomass inside the circulating bed and thus the combustion behaviour. Moreover, the chemical composition of biomass (containing e.g. alkali and alkaline earth metals) can be problematic.
The main deliverable from this project is a basis for design of biomass-fired CFB boilers for heat and power generation. The objective is to improve the design tools and modelling methods concerning combustion of biomass in circulating fluidized bed at scales ranging from small scale to utility scale units. With improved tools and models, the new boiler units can be optimally designed and operated, which increases the performance, availability and efficiency and decreases the emissions of the power plants using biomass. The results from the project and the experiences gained of biomass firing will encourage European utility companies for increasing the usage of biomass as primary fuel in new power plants or as a secondary fuel in co-combustion in existing power plants currently using fossil fuels. This will support the EU's renewable energy strategy.

FLEXI BURN CFB project aims to develop and demonstrate a power plant concept based on the Circulating Fluidized Bed (CFB) technology combined with Carbon Capture and Storage (CCS). The plant will be based on the super critical once through (SC OTU) technology and oxygen-firing with carbon capture, hence, providing high efficiency, operational flexibility and potential for an almost 100% reduction in CO2. The fuel flexibility of the CFB technology enables the utilization of indigenous fossil fuels with simultaneous co-firing of biomass. Thus, the technology provides potential for addressing the needs for climate change mitigation, security of supply and reduction of dependence on imported coals.
