Abstract:
An apparatus for controlling preheating temperature of equipment having a device to be preheated and a preheating device for start-up, said preheating device including a heat source and a heat source control device which has a plurality of heating patterns to control said heat source, said apparatus comprising:a temperature measuring device for measuring current temperature of said device to be preheated within said equipment; a computing device for calculating a predicted time that is required by said preheating device to preheat said device from the current temperature to a preset temperature; a comparison device by which said predicted time as calculated by said computing device is compared with a specified start-up time; and a selecting device for selecting from said plurality of heating patterns within said heat source control device a heating pattern that makes said predicted time shorter than said start-up time.
