In accordance with the present invention, there is provided a steam desuperheater which is integrated into a steam line. The steam desuperheater comprises a segment of steam pipe having one or more spring loaded spray nozzles attached thereto. Installed within the interior of the steam pipe of the desuperheater is a liner. The desuperheater is also provided with a steam flow measurement sub-assembly comprising a differential pressure transmitter including a pair of pressure gauges which are operatively connected to respective ones of a first pressure tapping which is formed in the steam pipe before the liner, and a second pressure tapping which is formed in the liner. The measurement of the differential pressure allows for a determination of steam flow through the desuperheater. In addition to the differential pressure transmitter outfitted onto the steam pipe, the steam flow measurement sub-assembly further preferably comprises pressure and temperature transmitters which are installed in the steam line upstream of the desuperheater for providing a density determination that is also required for the steam flow determination.
A steam desuperheater for integration into a steam line, the desuperheater comprising:
A method of measuring steam flow through a desuperheater, comprising the steps of:
In a steam desuperheater comprising a steam pipe having an inlet end, an outlet end, and an inner pipe surface defining a pipe conduit for containing a flow of superheated steam, a liner mounted within the steam pipe and having an inlet end, an outlet end, and an inner liner surface defining a liner conduit for containing a flow of superheated steam, and a spray water sub-assembly attached to the steam pipe and including at least one spray nozzle assembly which extends into fluid communication with the liner conduit, the improvement comprising:
