Inside the yankee, the steam condenses and transfers its heat to the shell. The resulting condensate must be removed at the same rate as it forms in order to maintain the efficient transfer of heat to the sheet. The condensate removal equipment includes the condensate headers, soda straws, riser pipes, and central steam collection pipe. The condensate headers receive condensate collected by soda straws in the grooves of the shell. The condensate is carried away from the headers by the riser pipes to the central steam collection pipe. The soda straws are thin pipes that extend from the condensate headers into the centers of the grooves inside the dryer shell. Because the pressure inside the dryer is higher than the pressure inside the condensate headers, the condensate plus some steam, flows up the straws into the headers.
