In late June, the super heaters were removed from 576.  Each unit has 4 sets of curved parallel pipes that send steam back into the tubes re-using the heat from the boiler to convert the saturated steam into dry steam. The longer pipes in the front are for the super heaters along the bottom. The units in the middle and the top are tucked behind the front row. (taken from Nashville Steam Facebook page)
