Actual of PaperMachine Operation by PaperMachine/CoatedMachine Operation Saport Toor

Abstract

It has not put to practical use that operating control is done by measuring wet paper web moisture content of each part on a paper machine, due to technically unavailable to measure moisture of each part and to less affected to web breaks with the variation of web moisture depend on decreasing open draws. While operators have the know-how to indirectly estimate web moisture from monitoring steam consumption of dryers and web runnability.
Now, we have developed new processing technology that indicate easily the moisture content and dewatering rate/dryness after the forming section, all press nips and drying cylinders on real-time. This technology is based on : (1) processing technology that can analyze drying trend at dryer section (2) available measuring equipment that can measure dewatering rate of individual press efficiently (3) personal computer which became cheaper and higher performance, etc.
As a result of applying this technology to real time operation monitoring and operation control over one year, it has been proved to be effective for rational papermaking.
We have commercialized this system as “MOAS”, Machine Operation Analysis System for papermaking and coating.
