Abstract
a presente invenção refere-se a um processo para operação de uma máquina de papel (10) para produção de papel, cartolina ou papelão, com um dispositivo de transporte (16), por meio do qual pelo menos uma peça de material fibroso (14) produzida de uma suspensão de fibras é transportada em uma direção de transporte, com pelo menos uma região de secagem (20), em que a peça contínua de material fibroso (14), que é transportada pela região de secagem (20), é seca por meio de pelo menos um cilindro de secagem (26), ao qual é aduzido um primeiro meio para a secagem da peça contínua de material fibroso (14), e com pelo menos um cilindro de alisamento (28) seguinte ao cilindro de secagem (26) em direção de transporte, por meio do qual a peça contínua de material fibroso (14) é alisada em pelo menos um lado, sendo que ao cilindro de alisamento (28) é aduzido um segundo meio para aquecimento do cilindro de alisamento (28), sendo que o primeiro meio é descarregado do cilindro de secagem (26) e aduzido como fonte de calor a uma bomba de calor (34), por meio da qual o segundo meio é aquecido.The present invention relates to a process for operating a paper machine (10) for producing paper, cardboard or cardboard, with a conveyor (16), whereby at least one piece of fibrous material (14) is used. ) produced from a fiber suspension is carried in a transport direction with at least one drying region (20), wherein the continuous piece of fibrous material (14), which is carried by the drying region (20), is It is dried by means of at least one drying cylinder (26), to which a first means for drying the continuous piece of fibrous material (14) is provided, and with at least one straightening cylinder (28) following the drying cylinder. (26) in the transport direction, whereby the continuous piece of fibrous material (14) is smoothed on at least one side, and to the straightening cylinder (28) is provided a second means for heating the straightening cylinder ( 28), the first medium being discharged from the drying window (26) and fed as a heat source to a heat pump (34), whereby the second medium is heated.
