Objective: To develop a high-efficiency FLEXI BURN design for a CFB boiler operating with sliding pressure once through steam cycle and air-/oxygen-firing modes by
a) carrying out RTD work to extend the existing elementary knowledge of air-firing to oxygen-firing in a circulating fluidized bed (CFB) boiler that is in a CO2 - H2O- rich atmosphere differing considerably from that of normal combustion with air
b) extending and validating design tools for a CFB boiler based on elementary knowledge and experimental data from pilot plants and the commercial-scale field measurements
Objective: To demonstrate flexible air- and oxygen-firing with CO2 capture at a large pilot-scale CFB and verify the operation of a commercial-scale high-efficiency SC-OTU CFB in order to produce appropriate scale-up information by
a) demonstrating air/oxy fl exible CFB operation on the 30 MWth scale (air- and oxygen-firing) with different kinds of local fuels and CO2 capture
b) test campaigns at the world’s first and the largest high efficiency SC-OTU CFB of 460 MWe (air-firing)
Objective: To develop the overall plant concept for the reliable, safe and economical carbon capture with advanced circulating fluidized bed combustion (CFB) technology that can operate under air- and oxygen-firing mode, enabling CO2 separation and capture for geological storage by
a) integrating a air/oxy flexible CFB boiler with an air separation unit (ASU) and CO2 processing unit (CPU) in order to create an optimized overall power plant concept
b) verifying the feasibility and readiness for the utilization of the technology within different regions of the EU
To create the readiness to start engineering
of a commercial scale demonstration of an air /
oxy flexible CFB power plant with CCS that is
applicable to various local conditions within
the EU by the end of the project.
Development and demonstration on multiple scales - Principle of demonstration steps towards air/oxy flexible CFB concept.
