How to control the heating rate during furnace drying
Thread Content
How is the heating rate controlled during furnace drying? For example, how can heating at a rate of 20 degrees Celsius per hour be precisely controlled?
What is the method used for heating the furnace? Oil? Gas? Or something else? The heating rate is determined in accordance with the furnace drying curve provided by the manufacturer of the furnace lining. After the measurement points are installed, the opening degree of the fuel valve, the opening degree of the flue dampers, and the flow rate of the medium inside the furnace tubes are adjusted as appropriate based on the actual temperatures measured (this method is not recommended; it is better to monitor the temperature at the outlet of the medium) in order to control the temperature rise curve
Half an hour at 10 degrees is fine; it’s not that strict – as long as it doesn’t exceed 20 degrees, that’s okay
