ABSTRACT Two or more compartments or steam chamber increments are sep- arated by intermediate walls, and headers or conduits lead into such compart- ments for individually supplying steam thereto. The bottom wall of the compart- ments has longitudinal slots through the length thereof for discharging steam from the compartments down on a pulp mat. These slots are formed by upwardly and inwardly turned extensions on the side walls of the chamber in combination with one or more V-shaped troughs, and the upper edge portions of these extensions and the troughs have reversely turned ends for supplying rigidity to these mem- bers. In one arrangement, horizontal headers or conduits extend in from one end wall of the steam chamber and have steam supplying portions in the respective compartments. These headers are supported in end walls of the compartments, and tubular supports are mounted on the end or intermediate walls to support the inner ends of the headers and allow expansion and contraction of the headers resulting from temperature changes. In another embodiment, a common steam supply header is employed and individual conduits or hoses extend into the com- partments. The individual compartments may be of varying length and the steam supplying members are of the necessary size and associated with steam inlet control means to furnish the required volume of steam. - 1 -
