Abstract
A method for increasing the drying capacity of a steam group (6) in a drying section of a pulp or paper machine. According to the method, a main steam flow (3) having a first steam pressure is fed to the steam group (6), the main steam flow (3) is conducted to at least one thermocompressor (9), which is driven by motive steam (4) having a second steam pressure, which is driven by motive steam (4) having a second steam pressure, which is higher than the first steam pressure, and the output steam (13) of said at least one thermocompressor (9) is fed to the steam group (6), the steam pressure of the steam that is fed to the steam group (6) being higher than the first steam pressure.
