Reel-up Secti on the opti ons were limited so, aft er an extensive review of all potenti al opti ons ABB’s Network Platf orm 700 was chosen due to its industry-leading compact installati on footprint. The result made space more available. This greatly assisted
Stoneywood in the mechanical installati on of the scanner as major civil and mechanical work would have been necessary to install a Network Platf orm 1200. Had the NP1200, or similar, been the only opti on this would have raised the overall project costs (by about £250,000 or 25 per cent) but also extend the shutdown period by up to ten days with a huge knock-on eff ect due to lost revenue. As an added bonus, Arjowiggins and ABB agreed to include the
boiler controls within the project scope. This allowed the mill to remove the MOD30 controllers which controlled the drum level and the fuel loops. This has also been a great success. The overall result has been measurable improvements in net producti on, saleable paper and mill profi tability. They are the result of
Arjowiggins personnel having access to, and having confi dence in, much more reliable and accurate informati on from the QCS 800xA system. The system is also automati cally providing faster and more accurate measurements to the control algorithms which in turn are now calculati ng the required process changes much more quickly and with greater accuracy to get the process variables to target
