Heating device for furnace installation, has flue gas circuits and heat air circuits that are connected with several furnaces, such that furnaces are simultaneously heated

摘要

The heating device (2) has combustion chamber, flue gas circuits (3) and heating air circuits (4). The flue gas circuits and heat air circuits are connected with several furnaces (5,6), such that the furnaces are simultaneously heated. The heating air circuits are coupled to flue gas circuits via heat exchangers, respectively. An independent claim is included for method for heating furnaces.
