The super-heated steam circulatory system begins with the 688ºF dry steam coming from the steam drum via the steam outlet connection piping to the primary super-heater inlet header. The steam circulates through the primary super-heater inlet and outlet tube banks, circulating up and down until it reaches the primary super-heater outlet header.
