    摘要： The present invention describes a system for drying a web-like paper sheet. The system comprises at least one drying device (12) capable of blowing high temperature dry air, supplied under pressure through one or more inlet conduits (20) on the web-like paper sheet, and of sucking from such a web-like paper sheet the moist air, ejected through one or more outlet conduits (22) connected to a recirculation conduit (26), and a combustion system (20) which comprises at least one hot gas generator (14) of the so-called direct type, provided with a system (16) for supplying fuel and a system (18) for supplying combustion air. The hot gas generator (14) consists of a burner (32), operatively connected to the system (16) for supplying fuel and to the system (18) for supplying combustion air, and of a combustion chamber (38) which is placed in direct fluid communication with the burner ( 32) by interposing a connection conduit (40). Outside the combustion chamber (38) at least one cooling channel (34) is provided, which encloses such a combustion chamber (38). The cooling channel (34) is placed downstream of the burner (32) and is operatively connected to the recirculation conduit (26), so that the hot gas generator (14) is capable of generating an air and burnt gases mixture which forms the dry air, as well as receiving, through such a recirculation conduit (26), at least part of the moist air so that it can be heated and reutilised by the drying device (12).

    摘要： An evaporative drying and desiccating system (10) for a web-like paper material is described. The system (10) comprises at least one first drying device (12), of the pressurised rotating cylinder type fed by steam, on which the web-like paper material to be desiccated is dynamically wound. The cylinder (12) contains a pipe system, for the removal of the condensate, inside it. The system (10) thus comprises at least one second drying device (14), of the hood type, which at least partially covers the cylinder (12) and that comprises at least one first burner (16) capable of producing high temperature dry air. The hood (14) is both capable of blowing the high temperature dry air onto the web-like paper material wound on the cylinder (12), and sucking the moist air released from such a web-like paper material. Positioned along the pipes (26) for releasing the moist air from the hood (14), there are at least one waste heat boiler (34), fed by the moist air released from the web-like paper material and capable of generating high pressure steam for feeding a thermocompressor (36) and a make-up valve (70), which supply steam to the cylinder (12), and at least one auxiliary burner (58), capable of increasing the temperature of the moist air coming from the hood (14). The system (10) is finished off by an exhaust and recirculation fan (32) and by a recirculation and balancing pipe system (72) that, together with the release pipes (26) and through one or more adjustment proportioning valves (64; 38), make it possible to regulate and balance the air flows. It is thus superfluous to use a fuel boiler for feeding the cylinder (12), making it possible moreover, for the thermal conditions of the hood (14) and of the waste heat boiler (34) to be independently regulated, and the amount of energy required by the system (10) is reduced.
