摘要： The invention relates to a method for recovering heat in a drying section (2) of a machine for producing a material web, in which drying section the material web is dried at least by a heatable drying cylinder (TZ) and by hot air by means of at least one high-temperature drying element (3), an exhaust air flow (LA) being produced thereby. At least part of the waste heat of the exhaust air flow (LA) is fed to an evaporation system (4) arranged in the exhaust air flow (LA) of the high-temperature drying element (3) by means of at least one heat exchanger (W1) in order to generate steam (D) for at least one steam consumer (V). The invention is characterized in that processed feed water or fresh water is used as a starting fluid (AM) for generating steam (D), said water being heated by means of waste heat from the exhaust air flow (LA) and fed into the evaporation system (4) and, in the evaporation system, either being at least partially evaporated such as to produce a mixture of steam and condensate (DKW1), preferably completely evaporated such as to produce steam (D) at the at least one heat exchanger (W1), or being heated in the heat exchanger (W1) and depressurized after exiting the heat exchanger (W1).

摘要： The invention relates to a method for recovering heat for a drying section (2) of a machine for producing a material web, in particular a fibrous web in the form of a paper web, cardboard web, or tissue web. The material web is dried at least by a drying cylinder (TZ), which can be heated with steam, and by hot air by means of at least one high-temperature drying element (3). A starting fluid for generating steam, such as a condensate and/or feed water, is fed to at least one heat exchanger (W1) in the exhaust air flow (LA) of the high-temperature drying element (3), wherein said at least one part of the condensate (K2) absorbs heat from the exhaust air. The invention is characterized in that the at least one part of the condensate (K2) developing in the drying cylinder (TZ) is evaporated in the heat exchanger (W1) at least partially such as to produce a mixture of steam and condensate (DKW1) and preferably completely such as to produce steam (D).

摘要： The invention relates to a method and a system (1) for recovering heat for a drying section (2) of a machine for producing a fiber web (F), in particular a paper, paperboard, or tissue web, using the exhaust heat of the exhaust air flow (LA), comprising a steam-heated drying cylinder (TZ) and at least one high-temperature drying element (3). The invention is characterized in that the at least one part of the condensate (K1) from the condensate separating stage (S) that is connected downstream of the at least one drying cylinder (TZ) is either at least partially evaporated, preferably completely evaporated, in the heat exchanger (W1), thereby generating a mixture of steam and condensate (DKW1), or heated in the heat exchanger (W1) and expanded while being at least partially evaporated after exiting the heat exchanger (W1). The steam is at least partially fed into a steam line (20) or a steam container, said steam line (20) and/or steam container being at least indirectly connectable to at least two steam consumers (V1, V2, V3, V4, V5, V6), and the steam line (20) and/or the steam container is selectively connected to at least one of the steam consumers (V1, V2, V3, V4, V5, V6).

摘要： The invention relates to a method for heat recovery for a drying section of a machine for producing a fibrous web (F), in particular a paper, cardboard or tissue web, wherein the fibrous web (F) is dried at least with a steam-heated drying cylinder (1) and at least one high-temperature hood (L1) by way of hot air, wherein the at least one drying cylinder (1) is loaded at least partially with fresh steam (D1), wherein the condensate/steam mixture (K1) of the at least one drying cylinder (1) is fed to a condensate separator (A1), wherein the steam (D3) is fed from the condensate separator (A1) to the fresh steam (D1) or a fresh steam/high-pressure steam mixture (D1,2), wherein at least one part of the condensate (K3) is fed from the condensate separator (A1) which is connected behind the at least one drying cylinder (1) to a heat exchanger (W1) in the waste-air stream (L6) of the high-temperature hood (L1), and wherein the condensate (K3,4) is heated there and absorbs energy from the waste air (L6), is subsequently relieved by a pressure-reducing element (DR1) and, as a result, evaporates again at least partially. The method according to the invention is characterized in that the condensate (K*3,4) which is heated by the heat exchanger (W1) and was subsequently relieved by a pressure-reducing element (DR1) and was vaporized again at least partially as a result is fed at least partially as high-pressure steam (D2) into a steam line or a steam container, the pressure of which is higher than the pressure of the condensate separator (A1) which is connected behind the at least one drying cylinder (1). The application likewise relates to a device (100) for carrying out the method according to the invention.
