In the process and power industries, steam is used both to perform mechanical work, such as driving a turbine, and as a heat transfer fluid. Unfortunately, both functions are accomplished best with steam properties at opposite ends of a spectrum-dry superheated steam is at the high end, while desuperheated steam near its saturation point is at the low end. What complicates steam conditioning is temperature control, or desuperheating. This seemingly simple practice of adding water to steam to lower its temperature is actually quite complex because desuperheating leads to a temporary, two-stage, liquid-vapor flow with potential control difficulties. The three general process reasons for desuperheating steam are: to improve thermal efficiency of heat transfer processes by using steam near saturation, to control unintentional superheat from reducing the pressure of steam, to protect downstream equipment and piping from elevated temperatures and pressures. The goal of steam desuperheating is to reduce the temperature setpoint at the shortest possible piping distance and elapsed time while avoiding damage from two phase flow. A number of critical installation and application parameters influence whether or ot this goal is reached. The recently developed control device on such high temperature steam is the spray-type desuperheater for a power plant. Atomized water at a lower temperature is sprayed into the steam in order to reduce its temperature in pipe. The nozzle of desuperheater control valve for power plants can decrease temperature and pressure of super heated steam in pipe. In this study, we analyse the flow resistance and the fluid friction which are influenced by the pressure variation of cooling water injection in the nozzle with using numerical analysis.
