The Highest Nip Load Shoe Press in Japan-Energy Saving by Introduction of High Nip Load Shoe Press to the Container Board Machine

Abstract

As companies are expected to take environmental actions, Rengo established“Eco Challenge 020”as the company's environmental action plan and is strenuously working to reduce the carbon emissions by 32% in 2020 compared to 1990 levels. In addition, Saitama Prefecture, where Rengo Yashio mill is located, has set the reduction target of CO₂ emission by 13% in 2019 compared to the average level between 2002-2004 by enforcing the local regulation of global warming prevention since 2009. Moreover, energy saving is the urgent issue of Yashio Mill because of the raising fuel cost in recent years.
Against such a background, Yashio Mill PM1 (medium machine) introduced the high nip load shoe press with an aim of improving the productivity as well as reducing the steam consumption. The outline of the retrofit and an operating experience will be discussed in detail below.
