Exploring the Efficiency and Benefits of Pick Desuperheaters

If you are looking for a simple, cost-effective, and reliable way to cool steam to within 10°F of saturation, you could benefit from Pick Desuperheaters. 


What is a Pick Desuperheater?


A desuperheater is a device that reduces the temperature of superheated steam by injecting a controlled amount of cooling water into the steam flow. Superheated steam is water vapor at a temperature higher than the boiling point at a particular pressure. Superheated steam is often used in industrial processes, such as power generation, chemical and petrochemical production, and pulp and paper manufacturing.


The Pick Desuperheater is a water spray type desuperheater with a single nozzle. It is designed to match the existing steam line pipe diameter and flange rating, and it has no moving parts within the housing. It is intended for applications that have relatively constant steam flow and cooling water demand.

How does a Pick Desuperheater work?


The Pick Desuperheater works by spraying cooling water axially, in the direction of steam flow, through a nozzle located at the center of the housing. Cooling water is metered through a flow control valve that responds to a temperature feedback loop. 


It also features a thermal sleeve and a conical insert that isolate the housing from the cooling water spray and accelerate the steam to promote turbulence and mixing. The thermal sleeve prevents thermal stress and cracking in the pipeline, while the conical insert enhances heat transfer and water absorption. 


Pick Desuperheaters are custom designed and fabricated to meet customer specifications, such as diameter, material, flange rating, and maximum allowable working pressure. It can also be easily serviced by removing the nozzle through a flanged opening in the top of the housing.


Pick can provide the desuperheater only or as a complete system with cooling water flow control valve and instrumentation.  


Pick Desuperheaters are a great choice for cooling superheated steam in a simple, cost-effective, and reliable way.
