Abstract
A honeycomb seal cooperatively associated with a rotatable blade of a steam turbine having a cylinder, seal include a backing plate fixedly connected to a mounting portion of the cylinder, the mounting portion having an associated moisture removal channel. A plurality of rows of honeycomb cells extend radially inwardly from the backing plate so that each cell is open adjacent said blades. The said backing plate is perforated with at least one perforation for each honeycomb cell for communicating moisture collected in the honeycomb cells to the moisture removal channel of the mounting portion of the cylinder.
