The desuperheating and desuperheating in the market mainly consists of nozzle-type steam desuperheaters, including Venturi desuperheaters, fixed nozzle desuperheaters, and variable nozzle desuperheaters.
Nozzle-type desuperheater is suitable for applications characterized by large superheat and large steam pressure difference, and the steam after desuperheating is slightly superheated steam. The steam quality changes with the fluctuation of the steam load, too low load and too large load, and applications with large superheat fluctuations will cause the downstream steam quality to decline.
Another type of desuperheater is the water bath desuperheater. The main application features of the water bath desuperheater are applications where the steam pressure is low, and decompression will lead to insufficient downstream steam pressure; applications where the steam flow fluctuates greatly, especially for long-term low-load applications; the steam after desuperheating is dry Saturated steam, high steam quality and high redundancy.
The Watt water bath desuperheating and decompression system adopts multi-stage pressure regulation and one-time desuperheating control. Ensure the reliability of the equipment and the quality of the steam under any load, which is conducive to maintenance, inspection and repair.
On the basis of thermal and fluid calculations, the Watts water bath desuperheating and decompression system meets the basic requirements of saturated steam for heating. It can achieve: load accuracy adjustment range of 20%-90%, steam pressure fluctuation less than 0.2barg, and dryness of 99% % above, the non-condensable gas content is below 0.5%.
The water bath desuperheating and decompression station adopts complete system control, minimal customer intervention, and convenient and good man-machine interface. Watt water-bath desuperheating and decompression station is skid-mounted and supplied, and factory designed, assembled and debugged to ensure that the design requirements are met. Reduce on-site requirements. Provide high-quality stable dry saturated steam for heating equipment.
