Abstract
A steam coil apparatus for transferring heat between steam passing through the apparatus and air flowing past the apparatus, the apparatus including a plurality of spaced outlet tubes extending substantially parallel to one another in a direction generally transverse to the direction of flow of the second fluid, and a plurality of fins or other extended surface attached to the outlet tubes and extending generally transverse to the outlet tubes. A plurality of inlet tubes are provided, each being received within one of the outlet tubes and formed of a diameter smaller than the diameter of the outlet tube within which it is received. The inlet tubes are provided with axially spaced orifices through which the first fluid passes from the inlet tubes to the outlet tubes. An outlet header is provided in fluid communication with the outlet tubes, and first and second opposed inlet headers communicate with the inlet tubes. The first inlet header communicates with a first set of the inlet tubes and the second inlet header communicates with a second set of the inlet tubes, wherein each inlet tube of the first set is spaced from each adjacent inlet tube in the first set by an inlet tube of the second set.
