It is very important to ensure that the temperature is just right during the drying operation of a biomass pellet hot air furnace, because too high a temperature may cause the material to overheat or burn, while too low a temperature may not achieve the desired drying effect.Accurate temperature control:Use high-quality temperature sensors: Ensure that the hot air furnace is equipped with high-precision temperature sensors to accurately measure and feedback the actual temperature.PID controller: Use a proportional-integral-differential (PID) control algorithm, which can automatically adjust the heating power according to the difference between the real-time temperature and the set temperature to achieve precise temperature control.Preset drying curve:Set the drying curve according to the material characteristics: Different materials have different sensitivities to temperature, so it is necessary to set a suitable temperature curve according to the specific drying object. For example, for some fragile or easily deformed materials, it may be necessary to slowly increase and decrease the temperature.Regular calibration:Regularly calibrate the temperature sensor: Since the sensor may deviate over time, regular calibration can ensure the accuracy of the temperature reading.Monitoring and adjustment:Real-time temperature monitoring: View temperature changes in real time through the control panel or remote monitoring system, and adjust the settings in time.Set up an alarm system: When the temperature exceeds the set safety range, the system should automatically sound an alarm and take corresponding measures, such as reducing the heating power or stopping heating.Optimize combustion efficiency:Reasonably adjust the supply of biomass pellets: Ensure that the fuel is fully burned and provide stable heat by adjusting the feed rate and the air supply to the combustion chamber.Use efficient combustion technology: For example, use secondary combustion technology to improve combustion efficiency and reduce heat loss.Insulation and heat preservation:Good insulation design: Ensure that the shell of the hot air furnace has good insulation performance, reduce heat loss, and keep the internal temperature stable.Maintenance and cleaning:Regularly clean the combustion chamber and heat exchanger: Ash accumulation and impurities will affect the heat transfer efficiency and cause inaccurate temperature control.Operation training:Train operators: Ensure that operators understand the correct operation method and temperature control strategy of the equipment to avoid temperature deviation caused by human errors.Through the above measures, the accuracy and stability of temperature control in the biomass pellet hot air furnace during drying operations can be effectively ensured, thereby improving the drying quality and saving energy.
