Abstract
A method for controlling supply of heat energy from a furnace to multiple dryers includes: determining a preset temperature, a preset humidity and a drying time for each of the dryers; calculating heat energy demand of each of the dryers according to the preset temperature, the preset humidity and the drying time of a respective one of the dryers, and calculating a fuel amount to be supplied to the furnace, and a volume of hot air to be supplied to each of the dryers; detecting a drying temperature in each of the dryers; and for each of the dryers, comparing the drying temperature and the preset temperature of the dryer, increasing the volume of hot air when the drying temperature is lower than the preset temperature, and decreasing the volume of hot air when the drying temperature is higher than the preset temperature.
