Procedure for regulating a vapour drought, a vapour drought and a bioenergy combination, and use of the procedure.

摘要

The invention concerns a process for regulating a vapour drought that has a closed circulation system in which dry vapour is circulated in the circulation system by a turbomachine, a material is dried by heat transfer from the dryer, the material is separated from the dryer, at least one dry run parameter and/or a material parameter is measured, and the mass flow of the circulating dry run is regulated in relation to the measured parameter(s) or unmet parameters; the inventory also refers to a vapour drought (1) for drying materials (2) regulated according to the procedure includes an end; circulation system (3),a turbomachine (5) connected to the circulation system (3)for generating a dry vapour flow (15) through the circulation system, a dry space (6) connected to the circulation system where the material (2) is dried by heat transfer from a hot dryer (15);at least one heat exchanger (7) connected to the circulation system (3) for heating the dryer;a separator (8) connected to the circulation system for separating the dry material from the dryer, a measuring device (M) for measuring at least one dry vapour parameter and/or a material parameter; and a control and control system (14) for controlling the mass flow of the circulating dryer relative to the measured parameter(s), including a bioenergy combination and the use of the drying process for different materials.
