Procedure for control and regulation of drying process, esp. in paper mfr.

摘要

A procedure entails control and regulation of a, esp. paper, drying process where different energy flows, each individually variable, are utilised. The flows are measured continually and the ratio of the energy flows one to another is instantaneously adjusted by steps till total energy costs, w.r.t. pre- specified specific costs for each energy type, attains a min.. Also claimed is a process control and regulation system where an optimisation system is connected to the process conduction system to achieve and regulate a desired prod. quality.
