An ever-increasing need for steam at specific temperatures and pressures exists in many modern plants. Fortunately, significant improvements have been made to increase operational thermal efficiency and heat rates by the precise, coordinated control of the temperature, pressure and quality of this steam. But, much of the steam produced in power and process plants today is not at the required conditions for each application, so conditioning is required, often by a desuperheater system.

When specifying a desuperheater, it is advisable to consult with the manufacturer because most desuperheater suppliers have multiple models from which to choose. Critical parameters (figure 2) include:

Spray-water temperature.

Spray-water pressure.

A desuperheater nozzle has a specific flow coefficient (Cv). A control valve also has a range of flow coefficients based on its design. The flow coefficient for the valve and desuperheater must be matched so that overall system flow coefficient is optimized.

It presents results in the thermal energy recovery system (TERS) investigation, and the possibility of introducing them to production vehicles as subsystems. This prospective new technology should reduce dependence on fossil fuels. One of the TERS systems' research objectives is to create a sustainable, electrical power source, suitable for the energy to be stored and later used in the electrical vehicle driving mode (EV)1. It will also lower the impact on the environment by reducing fuel consumption through the application of automotive thermoelectric generators (ATEG) instead of classical alternators that convert mechanical energy to electrical.

Pressure reducer and desuperheater system (PRDS) is used for Steam Conditioning Services for reduction of pressure and temperature of steam. Suitably designed pressure reducing valve installed on superheated steam line, reduces steam pressure to desired operating pressure. The steam temperature is reduced close to saturation by injecting water into high velocity steam by controlled water flow through water control valve and often injected into the steam where steam velocity and turbulence are at their highest, which gives quick and efficient cooling. The purpose of this project is to optimize the Pressure reducing and desuperheating system to overcome the current losses such as valve leakage, gland leakage and header leakage.
