GER-3646D - Steam Turbines for Large Power Applications

2019-10-4 · Modern GE steam turbine designs for electrical power generation are the result of more than 90 years of engineering development. The product line of fossil-fueled, reheat steam turbines for both 50Hz and 60Hz applications extends from 125-1100 MW and is based on a design philosophy and com-mon characteristic features that ensure high relia-

5. Steam Turbine Performance - Engsoft

2015-5-11 · 5. Steam Turbine Performance Historically, turbines have been designed to have 5% margins above required rated steam flows and pressure to provide for manufacturing tolerances and variations in flow coefficients. Therefore, the steam flow is 5% greater than that required for rated output with rated steam pressure (normal

2019-12-21 · Two rules of thumb for choosing the right flow characteristic: If most of the pressure drop is taken through the valve and the upstream pressure is constant, a linear characteristic will provide better control. If the piping and downstream equipment cause significant resistance to the system, equal percentage will provide better control.

BASICS OF STEAM TRAPS

2011-8-7 · THERMODYNAMIC STEAM TRAPS Essentially, a thermodynamic steam trap is a time cycle device which responds to imbalances of pressure applied to a valving device, usually a disc.

What is Steam Turbine - Description and Characteristics

2019-12-19 · Steam Turbine. In general, a steam turbine is a rotary heat engine that converts thermal energy contained in the steam to mechanical energy or to electrical energy.In its simplest form, a steam turbine consist of a boiler (steam generator), turbine, condenser, feed pump and a variety of auxiliary devices. Unlike with reciprocating engines, for instance, compression, heating and expansion are

Characteristics of boiler feedwater - Lenntech

Water absorbs more heat for a given temperature rise than any other common inorganic substance. It expands 1600 times as it evaporates to form steam at atmospheric pressure. The steam is capable of carrying large quantities of heat. These unique properties of water make it an ideal raw material for heating and power generating processes.

Linear or equal percentage valves: When should I use

2015-2-27 · Now the pressure drop across the valve is much lower, and a small change in valve position will not change the flow very much at all. In this case, an equal percentage valve is the appropriate choice because the characteristic of the valve offsets the effect of the piping. When the valve first opens a 5% change will not move the valve much.

An example was given for a super-critical, regenerative single-shaft, 2-casing with 2-exhaust steam turbine generation unit with air cooled condenser. The calcula-tion result was provided and compared with the result of the unit with wet cooling technology.

Miele DGD 4635 Pressure Steam Oven - Good Design

As the fastest and most powerful built-in steam oven in the world, the Miele DGD 4635 Pressure Steam Oven sets new standards in the kitchen. Like all Miele steam ovens, it is ideal for pressureless steam cooking, defrosting and reheating at precisely controlled temperatures between 40 and 100 degrees.

Control Valves and Flow Characteristics

2019-12-20 · These curves are based on constant pressure drop across the valve and are called inherent flow characteristics. the curve is called the Installed Flow Characteristic. In most applications, when the valve opens, and the resistance due to fluids flow decreases the pressure drop across the valve. Steam Control Valves

Properties of Saturated Steam - Pressure in Bar
