A steam blower box for applying steam onto a material web, particularly paper, which travels past the steam blower box. The steam blower box has a front and a rear limitation as seen in the travel direction of the material web and a steam chamber located between the front and rear limitations, wherein the steam chamber is open toward the material web. The steam chamber is closed off at its front and rear ends in the direction of travel by a limiting surface each of which protrudes in the direction toward the material web, and particularly forms a limiting edge; between the limiting surfaces, the steam chamber has a housing wall which is recessed relative to the material web. For achieving an air-free steam chamber of the steam blower box, a first steam outlet opening is provided in the housing wall immediately adjacent to the front limiting surface.
