Abstract:
1. An apparatus for passively desuperheating a superheated gas stream to saturated conditions comprising: a passive desuperheater for passively desuperheating a superheated gas stream to saturated conditions; a means for accumulating condensate in the passive desuperheater wherein the condensate has a liquid level in the passive desuperheater; an incoming stream of superheated gas entering the passive desuperheater below the liquid level of the condensate; a pressure means for controlling the incoming stream of superheated gas entering the passive desuperheater; an outgoing stream of desuperheated gas exiting the passive desuperheater above the liquid level of the condensate; a heat exchanger that utilizes the outgoing stream of desuperheated gas exiting the passive desuperheater wherein the heat exchanger is elevated above the passive desuperheater; a means for accumulating condensate in the heat exchanger; and a means for supplying the condensate from the heat exchanger to the passive desuperheater.
