A Closed Steam Hood Control System of Paper Machine Based on S7-300 PLC

Abstract:

After introducing the principle of ventilation and dehumidification for closed steam hood, the key and difficulty points of its control are analyzed. Aiming at the production line of coating white board with surface sizing and high steam consumption, DCS system of steam hood based on SIMATIC S7-300 PLC is designed. The hardware structure and control algorithms are illustrated in detail. The control system has been applied on the paper machine with nearly 10 board paper plants of the coating white board paper base in Fuyang, Zhejiang province, and the good energy-saving control effect has been obtained.
