Temperature control method and device of heat-conducting oil furnace and application of temperature control method and device

The invention provides a temperature control method and device of a heat conduction oil furnace and application of the temperature control method and device. The temperature control method comprises the steps that (1) an energy storage unit, a main heating furnace and at least one hot standby furnace are provided, and the main heating furnace and the hot standby furnace are independently and circularly connected with the energy storage unit; the energy storage unit provides heat energy with a target temperature for a user side; (2) controlling the main heating furnace to continuously supply heat to the energy storage unit; (3) a rated difference value is set, and based on the target temperature and the rated difference value, a temperature threshold value of outlet oil temperature change of the hot standby furnace is obtained; and (4) the real-time oil outlet temperature of the hot standby furnace is obtained, and the relation between the real-time oil outlet temperature and the temperature threshold value is
