Method and control system for controlling supply of heat energy from a furnace to mulitple dryers

摘要

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.

主权项

1. A method for controlling supply of heat energy from a furnace to multiple dryers, the method to be implemented by a control system and comprising:
(A) configuring the control system to determine a preset temperature, a preset humidity and a drying time for each of the dryers; (B) configuring the control system to calculate 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 to calculate a fuel amount to be supplied to the furnace according to the heat energy demand of each of the dryers, and a volume of hot air to be supplied to each of the dryers according to the heat energy demand of a respective one of the dryers; (C) configuring the control system to detect a drying temperature in each of the dryers; and (D) for each of the dryers, configuring the control system to compare the drying temperature and the preset temperature of the dryer, to increase the volume of hot air supplied from the furnace to the dryer when the drying temperature is lower than the preset temperature, and to decrease the volume of hot air supplied from the furnace to the dryer when the drying temperature is higher than the preset temperature.
