Abstract

A steam heat exchanger for a wood pulp dryer. The heat exchanger has a plurality of tubes extending between the ends of the heat exchanger in parallel,spaced-apart relationship to each other. A plurality of fins is connected to the tubes.
There is an outlet header near the bottom of the heat exchanger, the outlet ends of the tubes being connected to the outlet header. There is a steam inlet header near the top of the heat exchanger. The inlet header has an inner conduit with a plurality ofopenings spaced-apart therein for discharging steam from the inner conduit. There is an outer conduit extending about the inner conduit. The inlet ends of the tubes are connected to the outer conduit.
