Title:
HEAT EXCHANGE METHOD
Document Type and Number:
WIPO Patent Application WO/2002/003003
Kind Code:
A1
Abstract:
A heat exchange method capable of suppressing a loading on a rotating motor and a wear of a seal part and simultaneously performing a recovery of heat from exhaust gas and a reduction in NOx, comprising the steps of detecting the density of Nox in the exhaust gas exhausted from a furnace (10) such as a billet heating furnace and a billet heat treatment furnace having a rotating regenerative heat exchanger installed therein and controlling the speed of a rotor (3) by a controller (14) so as to increase the speed of the rotor (3) of the rotating regenerative heat exchanger when the density of Nox is increased, whereby the speed of the rotor is not required to be increased at all times for the maximum load of the furnace, and the load on the motor and the wear of the seal part can be suppressed.
