ABSTRACT:
The invention relates to an air impingement system arranged outside the jacket of an air impingement roll in the drying section of a paper machine or the like for heating and drying a web travelling around the said air impingement roll. The air impingement system comprises a mainly closed hood, which has control means for directing air onto the paper web. From the hood, air is directed by blowing with at least one fan to the blower nozzles and back again into the said hood as a circulation air process, and the system incorporates at least one heating device for heating the air. The air impingement system's hood and its said equipment are used in conjunction with an air impingement roll, which is of the size of approximately 1.5–2 m in diameter. The hood of the air impingement roll is at maximum 5 m high, preferably only 1.5–2.5 m high.
