Patent ID: 7980535

Claim:
A steam dispersion system comprising: a header; a divider dividing the header into first and second interior chambers, the first and second interior chambers generally not being in fluid communication with each other, the header including a first inlet for inletting steam into the first chamber and a second inlet for inletting steam into the second chamber; a first plurality of steam dispersion tubes and a second plurality of steam dispersion tubes extending from the header, the first plurality of steam dispersion tubes communicating only with the first interior chamber, the second plurality of steam dispersion tubes communicating only with the second interior chamber; a control system including a sensor for measuring a measured humidity value, a first valve regulating steam flow into the first chamber through the first inlet, and a second valve regulating steam flow into the second chamber through the second inlet, the first and second valves regulating steam flow based on a difference between the measured humidity value and a predetermined desired humidity value, the first and second valves operable between an open position and a closed position, wherein, when the difference between the measured humidity value and the desired humidity value is below a threshold point, only the first valve is in the open position, and, wherein, when the difference between the measured humidity value and the predetermined desired humidity value increases to the threshold point, the second valve also operably moves to an open position.
