What is Pressure Reducing Desuperheating Station?
Pressure Reducing Desuperheating Station ( PRDS Station ) is an important component of industrial equipment that converts high-pressure, high-temperature superheated steam into lower and regulated pressure and temperature (typically saturated steam) useful steam. This is done by integrating two key processes in which a pressure reduction step is undertaken whereby the atomized water is injected to cool the steam.
Working Process of Our Pressure Reducing Desuperheating Station
Pressure Sensing and Control: The high-pressure steam goes into the station and a control valve is automatically adjusted depending on the reading of the downstream pressure to downregulate the steam pressure to the required set point.
Temperature Measurement: The sensor constantly measures the temperature of the steam after pressure drop in order to identify the amount of superheat to be eliminated.
Water Injection: A special amount of fine, atomized cooling water is sprayed into the steam line via a desuperheater nozzle. The rate at which the injection is done is highly regulated in order to be fully evaporated.
Desuperheating (Cooling): The injected water immediately evaporates and absorbs the surplus heat energy of the superheated steam, reducing the temperature of the steam to a steady and saturated or slightly superheated temperature.
Why we are the Best Pressure Reducing Desuperheating Station Manufacturers in India
Accuracy in design and engineering: Our propriety of design and modelling techniques have been adopted to guarantee a high-turndown ratio and accurate control that are highly important in changing industrial requirements.
Strong Quality Assurance: All the parts including the control valve, the desuperheater, etc. are highly tested to ensure that they are stable in operations and have a long life in severe work conditions.
Tailor Made Turnkey Solutions: We do not sell off-the-shelf products, but rather we design and sell fully furnished site specific PRDS stations to the specific process parameters and layout requirements of the client.
Combined Type PRDS: A combination of the Pressure Reducing Valve (PRV) and a Desuperheater into one, smaller unit that is space and piping-saving.
Split Type PRDS: The PRV and the DSH are installed in two separate, distinct units providing flexibility but needing additional space and piping.
By Desuperheater Type
Spray Type: Sprays cooled water into the stream of steam; may have constant nozzle (constant flow) or variable nozzle (precise control).
Venturi Type: This is a nozzle that is in the form of a venturi used to provide high-speed steam, which is very important to provide perfect mixing and atomization of injected water.
Type of Atomizing Steam: This type uses minimal pressure of steam in order to disaggregate the cooling water into fine droplets to enable quick and accurate cooling.
By Type of Valve (to reduce Pressure)
Direct Acting PRV: Uncomplicated responsive valve for Pressure Reducing Desuperheating Station suppliers in India.
Pilot-Operated PRV: More sophisticated, more accurate.
