摘要： A temperature control system (50) for use in a furnace (10) for heating metal logs (13) as the logs (13) move through a furnace heating chamber (12) includes thermocouples (52a-52e) adapted to sense log temperatures by direct contact during intermittent time intervals when the logs (13) are stationary. Radiation sensors (64a-64 e) continuously sense radiant energy emitted from the logs (13) and a temperature compensation circuit (62) compares signals representative of log temperatures as measured by thermocouples (52a-52e) and the radition sensors (64a-64e). The difference between the signals is utilized during time intervals when the logs (13) are moving as a compensation factor for the continuous signals representative of log temperatures based on sensed radiation. The compensated signals and signals representative of desired set point temperatures are applied to log temperature controllers (80a-80e) to regulate the thermal energy applied to the logs (13).

摘要： An industrial heating furnace wherein hot exhaust gases from the furnace are heat exchanged in a rotary ceramic heat exchanger with air which is supplied to burners in the furnace for combustion air. The temperature of the gases within the furnace is controlled and the ratio of the flow of gases through the two sides of the rotary heat exchanger is controlled at a predetermined value which is approximately one to maximize efficiency of the furnace operation and to minimize thermal stresses on the ceramic heat exchanger.
