Rare radial steam turbine rejuvenated, Precision reverse engineering resolves vibration issues
Overhauling a steam turbine as part of a planned maintenance schedule is a regular task for many large-scale industrial enterprises that depend on these units to generate electrical power. However, for one pulp manufacturing plant in Eastern Canada, the refurbishment of its 25 MW Stal Laval radial steam turbine required expert engineering to resolve the vibration issue – the first time this repair has been completed in North America.
Lift-off: energy storage brings renewable energy to the mainstream
In the past, a severe shortcoming of renewables has been that they are intermittent: the power stays on only as long as the wind blows or the sun shines; if the wind blows too hard, the turbines must stop turning in order not to overload the grid. Newer and more efficient storage techniques are changing the equation. It is now possible to store excess power and tap into it during periods of power shortage. This article outlines some of the many technologies employed.
Effect of rotational speed on intergranular corrosion resistance of friction welded SDSS SAF 2507...
In this research paper super duplex stainless steel SAF 2507 has been selected to investigate the intergranular corrosion resistance of friction welded SDSS SAF 2507 joints. The joints were welded at three different rotational speeds: 700 rpm, 1080 rpm and 1600 rpm and three different friction pressures: 40 Mpa, 69 Mpa and 78 Mpa.
Stainless Steel World Conference & Exhibition 2017, 10th birthday party tops the charts!
Amidst a buzz of excitement and a cloud of golden balloons the tenth jubilee edition of SSW conference & exhibition kicked off from 28 to 30 November in Maastricht, the Netherlands. With a record number of attendees, a vibrant mix of familiar friends and new faces celebrated two decades of successfully bringing together the global CRA community. However the main focus was firmly on the future, judging where the industry is heading and helping exhibitors and delegates alike.
“Sustainability creates opportunities”
With time fast ticking away to the tenth Stainless Steel World Conference in November there’s already a buzz of anticipation about the topics that will be extensively discussed during the presentations and workshops. SSWN interviewed Catherine Houska about her keynote speech which is very encouragingly titled: Resiliency and sustainability create opportunities for stainless steel.
