Steam Calculators: Header Calculator

Using the Steam Property Calculator, properties are determined using Header Pressure and the Header Specific Enthalpy: Pressure = 265.6 psig; Specific Enthalpy = 532.0 btu/lbm [Steam Property Calculator] => Temperature = 210.7 °C; Assumptions. Inlet Mass Flows equal Outlet Mass Flow. Inlet Energy Flows equal Outlet Energy Flow. The combined

Temperature of Steam in a Turbine - The Physics …

A steam turbine consists of stationary and rotating blades on an axle. High pressure steam enters the turbine. The steam can be anywhere from 200 °C to 400 °C. The stationary blades direct streams of high pressure steam onto the rotating blades, which turns the axle. The steam then travels through two or more consecutive stages of stationary

Proper Sizing of Steam Header Drains Prevents Water …

2011-1-3 · Figure 3 shows a summary of these computations for P’ 2 (vent inlet pressure, top) and P 2 (vent outlet pressure, bottom) for the same steam header conditions and drain flow rates used to

Steam Calculators: Header Calculator - eere.energy.gov

Using the Steam Property Calculator, properties are determined using Inlet Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Step 2: Determine the Header …

Steam turbine flow & operation - Processing Magazine

What are the problems that can occur while running a …

Lower inlet pressure means lower inlet enthalpy. Thus you tend to get lower than predicted power output to a certain pressure provided the steam remains superheated at that pressure. This is why the machine vendors specify a particular range of pr

Development of Steam Turbine Inlet Control Valve for

2010-6-30 · The development in the steam turbine business is heading for applications with much higher steam parameters since this enables a raised efficiency. Steam parameters refer to the pressure and the temperature of the steam. The aim of this study was to generate concepts for steam turbine inlet control valves designed for higher pressure and

Steam Turbine performance with variation in inlet …

Steam Turbine performance with variation in inlet steam pressure Steam Turbine performance with variation in inlet steam pressure icecool (Mechanical) (OP) 26 Jun 14 02:10. If you drop the full load inlet pressure from 98 bar to 75 bar then the mass flow of steam thru the first row of blades will drop by almost 25% , hence the power output

Types of Steam Turbine - an overview | ScienceDirect …

The noncondensing type of steam turbine uses high-pressure steam and exhausts a lower-pressure steam to a header. • The condensing turbine exhausts to a surface condenser, which usually is a large exchanger with a hot well attached but may take the form of an air fan, to recover condensate. •
