How to ensure that the Paddy dryer is heated evenly
1. The air gate of the Paddy dryer should be reasonably controlled and the ventilation volume should be controlled. When the ventilation volume is too large, the damper should be lowered in time to ensure that the entire firing zone operates in a positive pressure environment, reducing the back wind. After the temperature in the dryer returns to normal, gradually increase the air gate to make the front fire open, and ventilate the rice dryer to speed up the burning of fuel and increase the heat in the rice dryer. When the ventilation rate is too small, the height of the air gate should be increased, so that the front part of the firing belt is in a negative pressure environment, and the rear part is in a positive pressure environment for material calcination. At the same time, the air intake volume in the heat preservation position and the cooling position is maintained to improve the combustion quality and heat exchange efficiency of the fuel, and eliminate the phenomenon of underfire in the rice dryer.
2. Change the calorific value of the fuel in the paddy dryer and appropriately increase the external fuel of the Paddy dryer. If the calorific value of the currently used fuel is higher than the heat generated by the original fuel incineration, reduce the amount of fuel increase, and vice versa Increase the amount of fuel added to the paddy dryer to maintain a balance of heat in the paddy dryer.
3. The temperature in the Paddy dryer should be detected, and the temperature in the paddy dryer should be accurately judged according to the changing trend of the temperature in the paddy dryer, and based on this, the increase in external fuel should be controlled. Ensure that external fuel additions are carried out in accordance with repeated minority guidelines.
4. It is necessary to detect the temperature in the Paddy dryer. According to the changing trend of the temperature in the paddy dryer, the temperature in the paddy dryer should be accurately discriminated, and it will be used as a control according to the increase of the external fuel. Ensure that the increase of external fuel is carried out in accordance with several guidelines to prevent the increase of too much or too little fuel from causing the temperature rise to be substandard or incomplete incineration.
