High consistency forming process for paper making. Part 1. A research, development, and demonstration program plan for the US Papermaking Industry. Final report
The subject of research, development, and demonstration (RD and D) of energy conserving technologies applicable to papermaking operations downstream of the pulping process is addressed. An RD and D Program Plan is presented based on a survey of leading representatives of the papermaking industry, equipment manufacturers, consulting engineering firms, the American Paper Institute, and the Technical Association of the Pulp and Paper Industry. For perspective, the program plan is presented against the general background of the industry's current issues and concerns. The second part of the paper, Phase I, final report, deals with papermaking test facilities. The case for a centralized test facility is discussed. The results of a survey of existing pilot paper machines are presented. The energy saving potential of high consistency forming is considered and related to existing evidence. Simple theoretical models for the press nip action and the drying process are developed to predict where high consistency forming will reduce energy consumption. A special dynamic former has been designed, fabricated, and commissioned to allow development of a laboratory high consistency headbox. The design and construction of a low speed headbox has been completed and the complete system operated. Special equipment and techniques for the measurement of the water and air permeability of sheet samples have been developed and are described.
