The invention discloses a heating control method and a heating furnace. The heating control method comprises the following steps that the current water outlet temperature and the water return temperature are collected; when the water return temperature is not smaller than a preset low threshold value, whether the first difference value of the water outlet temperature and the water outlet set temperature is larger than a preset first threshold value or not is judged; and when the first difference value of the water outlet temperature and the water outlet set temperature is not larger than a preset first threshold value, and the heating device is controlled to heat the current output power. According to the heating control method and the heating furnace, in the process that the heating device is started for heating and heating, the water outlet temperature and the water return temperature are introduced into the tube control of the output power of the heating device, so that the defect that an existing thermodynamic system cannot be combined with the water outlet temperature and the water return temperature for heating control is overcome, and the heating control method is beneficialto improving the heating effect.
Description
technical field [0001] The invention relates to the technical field of heating, in particular to a heating control method and a heating furnace. Background technique [0002] In a thermal system using circulating water as the heating medium, the outlet water temperature and the return water temperature are two important heating indicators, which are closely related to the heating effect. in the existing thermal system. For example, for gas heating furnaces, two thresholds are generally set to independently control the outlet water temperature and the return water temperature. For example, when the outlet water temperature exceeds a higher threshold, the thermal system is controlled to stop heating; when the return water temperature is lower than a lower threshold, the output power of the thermal system is increased until the return water temperature is not lower than the corresponding threshold. This control method is relatively simple. It only provides the conditions for ...
