3 3 RELCOM Objectives Development and Demonstration of Scaling Criteria for Oxy/Coal/RFG Burners Determination of Optimal RFG Rates Investigation and Prediction of Flame Instability Development and Demonstration of Improved Burner Designs Investigation of the Effects of Oxy/Coal/RFG / Firing on Gas-Side Corrosion

4 4 RELCOM Objectives Study of Oxy/Coal/RFG Conditions on Ash Deposition and Slagging Investigation of the Impact of Oxy/Coal/RFG on Exhaust Gas Cleaning Determination of Underpinning Fuel and Combustion Characteristics Development and Application of Improved Mathematical Models Simulation of Full Scale Oxy-Pulverised Coal Boiler Operation.

5 5 Work Programme RTD Demonstration Management WP1 Underpinning Technology WP2 Simulation i WP3 Burner Development WP4 Experimental Demonstration WP5 Process Demonstration WP6 Dissemination WP7 Project Management

6 6 WP1 - Underpinning i Technology Objective To develop further understanding of oxy/coal/rfg combustion technology by addressing the current technical uncertainties and barriers which have been identified Achievements Impact of oxy/coal/rfg atmospheres on radiation, devolatilisation & gasification Explosion characterisation Gas-side corrosion under high temperature Impact of oxy/coal/rfg on flue gas cleaning Impact of mercury

7 WP2 - Simulation of Oxy/Coal/RFG / Objective Processes To develop appropriate mathematical models and tools for reliable simulation of coal/oxygen/rfg firing in both medium and demonstration scale test rigs and power station boilers Achievements Comprehensive set of sub-models developed Identification of optimal recycle rate Zone model made available to the community 7

8 8 WP3 - Pilot Scale Burner Trials Objective To develop a greater understanding of the combustion behaviour of pulverised coal under oxy/rfg atmospheres Achievements Scaled second generation burner concept developed Flame monitoring system developed & tested

9 WP4 - Medium Scale Demonstration o & Objective Scale Up To demonstrate work conducted under WP2 and WP3 at a medium and large scale for coal/oxygen/rfg fired power station boilers Achievements Demonstration of new burner concept Determination and application of scaling rules Demonstration of combustion optimisation system Demonstration of CFD modelling subroutines 9

10 10 WP5 -Process ocesssimulation, uato Demonstration stato Objective & Exploitation To remove the barriers that currently exist to a full scale demonstration of oxy- combustion Achievements Optimal retrofit and new build ldboiler designs determined Zone modelling demonstrated for parametric analysis Integrated CFD/process simulation boiler models demonstrated Methodology to minimise efficiency penalty determined

11 WP6 -Dissemination and Technology ogy Objectives Transfer To ensure the effective dissemination and transfer of the technology developed in RELCOM to European stakeholders Achievements Project web site developed ( Oxy-fuel database developed Oxy combustion handbook developed Oxy sub-models disseminated Range of open workshops in collaboration with other interested parties undertaken 11

12 12 Lessons Learned 21% O 2 in the Primary Flue Gas Recycle (PFGR) stream is safe. 67% FGR is confirmed as being a good design point for simulated air oxyfuel firing. Acceptable steam conditions over a comparatively at narrow range of FGR. Once-through boiler design is more accommodating of oxyfuel technology.

13 13 Lessons Learned 1 st generation oxyfuel burner operates over an acceptably wide range of FGR rate. Lower FGR rates will need a boiler design that is specific to the desired operating condition. Need to develop 2 nd generation burners (with hdirect O 2 injection) and 3 rd generation burners (pure O 2 supply to the windbox). Minimum FGR rate is approx. 50% for conventional coal preparation This needs pure O 2 in a 3 rd generation burner.

14 14 Projected Adoption of Oxyfuel Technologies in Carbon Capture Paris limit global warming to 2 C by Adoption of CCS is critical CCS on coal - 531GW of coal by 2050 Post Combustion Capture technologies World - 2 Degree Scenario Gross electricity capacity (GW) Oil Coal Coal with CCS Oxyfuel* CCS on coal 531GW of coal by Natural gas Natural gas with CCS Nuclear Biomass and waste Biomass with CCS have dominated demonstration projects Geothermal Mix of technologies will be required Oxyfuel demonstrated at pilot- and largescale (Schwarze Pumpe, Callide) Key technology for Coal CO 2 abatement 25% of Coal with CCS is expected to Hydro (excl. pumped storage) G th l Wind onshore Wind offshore Solar PV Solar CSP Ocean Other Total Direct CO2 emissions (Mt CO2) Industry Buildings, agriculture, fishing, non-specified other Transport Power utilise Oxyfuel, resulting in up to 133GW Other transformation Total of global installed capacity by 2050 CO2 captured (Mt CO2) Industry Power Other transformation Total Source - IEA Energy Technology Perspectives 2015 Doosan-AMBER

15 15 Summary Only EU funded Oxy-coal project over last five years Removed significant barriers to full-scale demonstration Technology will be required in countries heavily dependent on coal Demonstration will need backing of government(s)
