Reheat attemperator
WebThe reheat coils of the HVAC system heat the air before it leaves the system. This prevents over-cooling of your room due to the low temperature of the dehumidified air. As a result, … WebHeating Surface Distribution The distribution of total SH heating surface area between the primary and secondary SH has a significant impact on attemperator performance. In fact, some HRSGs are installed with a SH surface area distribution that makes startup without exceeding the maximum SH outlet steam temperature limit thermodynamically impossible.
