US 10,533,284 B2 · Method for operation of a heating group subsystem, and heating group subsystem

Abstract

A method for operating a heating group subsystem of a machine for the production or treatment of a fibrous web. The heating group subsystem includes a first heating group and a last heating group and at least one additional heating group; in each case having at least one device that is heated with pressurized heating steam. Viewed in a direction of travel, the fibrous web is fed first through the first heating group, then through the at least one additional heating group, and thereafter through last heating group. The steam pressure of the heating steam of the at least one additional heating group is adjusted lower than the respective steam pressure of the heating steam of first heating group and of last heating group.

A method for operating a heating group subsystem in a machine for a production or treatment of a fibrous web, comprising:

providing a first heating group including at least one first device that is heated with a pressurized heating steam, at least one additional heating group including at least one additional device that is heated with a pressurized heating steam, and a last heating group including at least one last device that is heated with a pressurized heating steam;
feeding the fibrous web, when viewed in a direction of travel, first through the first heating group, then through said least one additional heating group and thereafter through the last heating group;
and
adjusting a steam pressure of said pressurized heating steam of said at least one additional heating group lower than a steam pressure of said pressurized heating steam of the first heating group and a steam pressure of said pressurized heating steam of said last heating group.

A heating group subsystem for a machine for a production or treatment of a fibrous web, comprising:

a first heating group including at least one first device that is heated with a pressurized heating steam;
at least one additional heating group including at least one additional device that is heated with a pressurized heating steam;
and
a last heating group including at least one last device that is heated with a pressurized heating steam, wherein the fibrous web—viewed in a machine direction—is guided first through the first heating group, then through said at least one additional heating group, and thereafter through the last heating group such that a steam pressure of the pressurized heating steam of said at least one additional heating group is lower than a steam pressure of the pressurized heating steam of the first heating group and a steam pressure of the pressurized heating steam of the last heating group.
