Article Synopsis
Advanced Joint and Syphon System for Optimal Heat Transfer and Temperature Profile Corrugating International, Vol. 2, No. 3 As corrugating machinery continues to evolve at faster speeds and the market demands higher quality products, the performance of the corrugating equipment becomes more critical. Efficient removal of condensate and heat transfer is important to ensure proper application of adhesive to the corrugated medium and liner board. An advanced steam joint and syphon system has been designed to maximize the heat transfer abilities of the rolls while providing for extended performance life of the joint and syphon equipment. The patent-pending design includes an adjustable syphon clearance from outside the roll and is built for both conventional steam heated rolls and peripheral gun-drilled rolls.
Aylesford Rebuilds Newsprint Machine Paper & Tissue Industry, May 2004 Aylesford's PM13, the older of its two newsprint machines, was recently rebuilt to improve the machine's efficiency and the runnability and printability of its product. Says Kevin Bussey, PM13's operations manager, "Our new steam and condensate system, combined with the most advanced dryer management system in papermaking, has allowed us to meet our goals quickly, and go far beyond expectations."
Barriers Up and Down at Newton Kyme Papermaker, Vol. 82, No. 9 StoraEnso's Newton Kyme coated barrier board mill in Yorkshire, England, is proof that a small specialty mill can find a niche and thrive in the age of giant machines. Competing against large-scale mills, Newton Kyme has found a way to design higher performance into the way its product performs in the marketplace, and the way it falls apart for re-use.
Corrstack Doubles Output With Small Capital Investment PIMA's Papermaker, Vol. 80, No. 10 The saying goes, when you are dryer limited, you can never reach full production. So how far can you go in raising production without spending major capital for adding dryer cans or a top former. United Corrstack, a Reading, Pa. corrugating medium mill, doubled its production to 350 tons per day (tpd) without adding a single dryer can, and by making only modest, incremental investments.
Czech Investment Proves to Be Cut and Dried Pulp & Paper International, Vol. 43, No. 12 In 2001 the Frantschach Steti mill in the Czech Republic built a new steam and condensate system for its PM5. The work resulted in a 15% increase in drying rate and higher quality sack kraft right from the start. Following the mill's steam and condensate system improvements, the mill's PM5 has achieved 20% greater output (up to 560 tonnes/day) and simultaneously reduced energy costs.
Dalum Picks Up Steam Pulp and Paper Europe, Vol. 4, No. 1 Thanks to a complete rebuild of the steam and condensate system for PM7, Stora Dalum in Denmark is conserving energy, reducing breaks, and cutting unscheduled downtime dramatically. The capacity of PM7 was boosted by 20,000 tons per year of coated and uncoated fine paper following the rebuild and additional gains are being made by fine tuning.
Donnacona Leaps Ahead Pulp & Paper Canada, Vol. 101, No. 12 A new day has dawned for the employees at Bowater's Donnacona, Quebec mill, a dawn that provides the promise of a secure future. The long-awaited new paper machine, PM4, started up October 22. One novel innovation is a modern dryer drainage system that uses advanced controls to increase sheet quality, eliminate flooding, and reduce energy consumption. The Johnson Dryer Management System system uses preprogrammed pressure curves for specific grades of paper to optimize drying.
Dryer Drainage Systems Move Into the Fast Lane TAPPI Journal, Vol. 82, No. 11 With many paper machines running at more than twice the speed of a decade ago, trying to maximize steam and condensate system performance is a formidable task. Full optimization requires on-line application of greater process knowledge for the sheet and papermaking process. Steam and condensate system design using advanced controls has recently reached a new plateau. This provides maximized sheet quality, increased productivity and reduced energy consumption.
Dryer Section Rebuild Yields Extra Production for Irving Paper PaperAge, Vol. 113, No. 1 The PMI rebuild has generated positive results for Irving Paper and a fast payback on their investment. With the dryer section designed to handle much higher drying rates, it is no longer a limitation to future production increases.
Drying Gains Push Augusta Newsprint's Efficiency to Top Tier TAPPI Journal, Vol. 82, No. 8 Steam savings and reduced flooding in the dryers occurred at Augusta Newsprint in Augusta, Georgia, USA, when it switched from dual-rotary syphons to stationary syphons from the Johnson Corporation, as part of an overall retrofit of the dryer section of its PMI newsprint machine.
Drying Gains, A Hidden Advantage for Paper Brands PIMA's North American Papermaker, Vol. 82, No. 6 If someone asked you to name the first ten brand names that come to mind, chances are a paper product would not be one of them. Microsoft, Yahoo, EBay and other software and Internet brand product names are at "top of mind", not to mention long-standing leaders like Coca-Cola and American Express. Upon reflection, however, names like Kleenex and Xerox have found their way into the collective minds of consumers. In fact, over the next decade paper brands will become more prolific, and many will become well known by consumers and niche markets. Fueled by the need to differentiate, many paper companies are actively pursuing brand development, and investing heavily in the process.
From Iron to Velvet to Gold: An interview with CEO Sabatka of Frantschach Steti mill Solutions, Vol. 85, No. 6 What is now the Frantschach Steti Pulp & Paper mill near Prague in the Czech Republic has evolved into a global model of success following its escape from a communist Kafkaesque bureaucracy. From the days of the Iron Curtain to the liberating "Velvet Revolution" in the Czech Republic to today's impressive profitability, the Frantschach mill stands out as an entrepreneurial model for the industry.
Improving Dryer Control Pulp & Paper International, Vol. 102, No. 4 Significant improvements in dryer section operation and energy efficiency have been achieved through the close integration of supervisory control and steam system design. Supervisory control of all system set points is used to optimize system operation and provide ease of use for the operators. Steam pressures, flows, and differentials are managed under machine operating conditions including sheet breaks, tail threading, grade changes and startups.
Kemiart Produces Vibrant Color from Icy White PIMA's International Papermaker, Vol. 82, No. 5 Consumer brands are the focus at Kemiart in Finland, where top liner is viewed as a superior vehicle for packaging. The company is a pioneer in alkaline boardmaking, setting a standard for printability and runnability on printing presses and converting equipment. In 1999, the press and dryer sections were rebuilt. Results included steam savings of up to 18% per ton of liner, based on a change in steam and condensate system piping, as well as new joints and syphons from The Johnson Corporation.
New PM4 at Bowater Donnacona Mill Paper Equipment & Materials International, Vol. 11, No. 3 As part of a major modernization project Bowater started up its new PM4 at the Donnacona mill at the end of 2000. This new 6.6 meter wire width paper machine, supplied by Voith Paper, will have a capacity to produce 152,000 tpy of SC paper grades once it reaches its operating speed of 1500 mpm. The new machine replaces two old machines PM1 and PM2 which have been decommissioned.
