Dynamic compressed air economiser device

摘要

The device has a single or multi-path radiation heating coil (14) arranged in a housing. The coil is held axially or radially in an optimally heat insulated chamber (HKS) enclosed by a reflecting sleeve (9). The chamber is divided into two air insulation chambers (H1,H2) and the chambers containing still air during the heating-up process. A small volume of compressed air is heated in the centre section around the radiation coil without any real heat loss.
