Product Description

  Desuperehater System Overview:

 

Desuperheaters, sometimes called attemperation or steam conditioning, is the reduction of steam temperature. Its most common application is the reduction of temperature in a steam line through the direct contact and evaporation of water. Most Desuperheaters incorporate the venturi design which uses the velocity of the steam to atomize the cooling water and resulting in final steam flow at the desired lower temperature.

 

 

In 1970, Hangzhou Worldwides Valve introduced its first mechanical desuperheater in China, and in 1976 the venturi desuperheater was developed and successfully marketed to satisfy a wide range of applications. During the development, we have full line of desuperheaters includes classical venturi design, double venturi, multiple spring nozzle and annular venturi desuperheater for selection. All desuperheaters are custom built for each specific application, ensuring trouble-free service and lead to numerous variations and larger capacities for critical power plant needs.

  Desuperehater System Structure:

 

As for different working conditions, we have many structure for desuperheater design. Also, we offer customized solutions with total system end to end station with all necessary mechanical and instrumentation components and take guarantee of entire control system.

 

 

  Highlights and Technology:

 

OPERATION PRINCIPLE

The desuperheaters reduce steam temperatures by introducing cooling water directly into the hot steam. Temperature reduction is essentially a matter of heat transfer, where the cooling water is placed in direct contact with steam and receives the necessary heat for evaporation.
After sufficient time, all of the liquid is vaporized, resulting in final steam flow at the desired lower temperature. Cooling water flow is controlled by a feed water control valve which responds to changes received from temperature controller or temperature control system. The water then passed through the main tube of desuperheater to the spray nozzle and discharges into header as a fine spray. By controlling the flow through the spray nozzles and maintaining proper header velocities, good reliable temperature is obtained.

 

VENTURI CONCEPT

The venturi design is based on a sophisticated concept. The upstream steam comes from venturi chamber with accelerated velocity, which turns the spray water and flows with it through the mixing module where steam and water meld together with very high contacting efficiency. The design brings many advantages including minimal pressure drop, shorter installation length and higher range ability, also there is no moving parts which ensure the stability and low maintenance cost in future operation.

 

MULTIPLE NOZZLE DESIGN

HZVALVE has incorporated the latest technology in the multiple spray nozzle design. The high quality spring loaded nozzle was employed and assembled with desuperheaters to atomize the water droplets and produce the heat transfer contact area necessary for cooling the steam so that to bring steam and water to meld together with very high contacting efficiency.

SPECIAL SPRAY EFFECT

The spray water enters the nozzle chamber through multiple tangentially drilled holes, thereby causing water to swirl within the nozzle chamber. The spring, which is pre-compressed to a certain set pressure, keeps the nozzle plug pressed against the seat. As soon as the pressure differential between the water & steam exceeds the set pressure, the plug lifts from its seat and the spray water exits through the small circumferential opening, in the form of a fine mist. Number of nozzles, spring range and spring set pressure is selected based on the process specifications.

Feed Water Control Valve

Feed water control valve is one of the most important control components of the feed water line, it controls the supply of feed water to the nozzles, the commonsense is the high performance of feed water control valve with accurate  flow and pressure controlling is the priority concern for the operation of desuperheater.

According to different working conditions and construction investment, we give full types that covers multi-stage type, cage guide type and labyrinth type and more.
