IMPULSE - Advanced Industrial Manufacture of Next-Generation MARBN Steel for Cleaner Fossil Plant

点击翻译按钮获取中文摘要

IMPULSE will work with novel "MARBN" high temperature steel, recently developed in TSB project "IMPACT" and shown tooffer capability for an increase in steam power plant temperature of 25 degrees C. IMPULSE, whose consortium includesmost IMPACT members together with new pipe, welding and innovative research partners, will take MARBN from thelaboratory on to full-scale industrial manufacture of ingot castings, pipework, and weldments. This will improve efficiencyand reliability of current and future steel-based steam power plant, and thus increase security of supply and reduce costand carbon emissions. MARBN 8-tonne ingot casting technology will be developed, and following high temperature (to1250 degrees C+) testing and manufacturing simulation, two full-scale pipe extrusion trials will be undertaken, with productvalidation by testing and electron metallography. Matching welding consumables will also be developed, qualified andtested. Long term creep and creep-fatigue data generation will feed into performance validation, materials standardisation,and pressure vessel design codes. Interaction with the KMM-VIN collaboration will enable constructive interchange withparallel European projects.The Nottingham team will provide the required expertise for testing MARBN specimens under creep and creep-fatigueconditions and developing the fatigue life model and the associated Finite Element modelling capabilities to enable the lifeprediction of welded MARBN pipes under flexible power plant operating conditions.
