The single-shaft combined-cycle power generation system; in which the gas turbine, steam turbine and generator (STAG™) are installed in a tandem arrangement on a single shaft; has emerged as a preferred configuration resulting from simplicity of controls and operation and demonstrated high reliability.
"Steam produced from a boiler drives a steam turbine, which in turn drives the electric generator. The low pressure exhaust steam from the turbine is supplying the required heat to the process. The condensed steam from the process is then returned to the boiler."
Steam Driven Generators: Steam Turbines and Electric Generators. A steam turbine driven generator, sometimes known as "turbo generators", can be best explained by understanding a steam turbine and a generator separately. A steam turbine is a steam-driven driver. Water is heated at an extremely high temperature to convert it into steam.
85% efficiency is achievable for high-pressure steam with an optional flue gas economizer package. We guarantee 85% efficiency on low pressure steam. 99% or better dry quality steam assures the highest possible steam process efficiency.
However, usage of small CHP systems is not widespread because systems currently on the market are limited by high price, low efficiency, and short lifetime. The GENSETS program seeks to develop 1 kW (electric) CHP generators that have high fuel-to-electricity generation efficiency, long life, low cost, and low emissions.

If the plant has only one steam generator (boiler), uses a single fuel, and has a single steam pressure level, it is relatively easy to assign a cost to the steam. However, in most cases, there are multiple steam sources and multiple fuels. There are also multiple steam pressure levels with multiple

and an air-cooled generator producing variable voltage and high-frequency AC power. This high-frequency AC output (about 1,600 Hz for a 30 kW machine) is converted to constant 60 Hz power output in a power conditioning unit. The recuperator is a heat exchanger that uses the hot turbine exhaust gas (typically around 1,200°F)
An industrial process steam generator normally includes an HPR (High Pressure Return) System to collect the condensate from the process so that it can be treated and returned back to the steam generator. An HPR system improves any steam system efficiency by 15-35% depending on operation so it is a good fit to American Heating Company's
A steam generator is used as a source of heat for thawing and de-icing aggregates. This low pressure boiler also speeds up the curing process for pre-cast concrete, pipe, pre-stress, block operations, saturating the curing area with steam, uniformly heating the concrete and speeding up the normal process.
A combined-cycle power system typically uses a gas turbine to drive an electrical generator, and recovers waste heat from the turbine exhaust to generate steam. The steam from waste heat is run through a steam turbine to provide supplemental electricity.
Jenbacher Gas Engines. INNIO's Jenbacher gas engines are available in the 0.3-10.0MW electrical output range for an individual generating set.

Heat Recovery Steam Generators The heat recovery steam generator (HRSG) provides the thermodynamic link between the gas turbines and steam turbines in a combined-cycle power plant. Each HRSG solution is custom-engineered to meet your desired operating flexibility and performance requirements.
The low exhaust gas temperature from gas turbines, typically ranging from 900 to 1050F, generates less steam on unit gas mass basis in the HRSG evaporator compared to a package boiler. On the other hand, in a steam generator or package boiler, the flue gas stream is cooled from adiabatic combustion temperature of 3300 F and hence generates a

For CHP applications, gas turbines typically have favorable economics in sizes greater than five MW. Gas turbines are well suited for industrial and institutional CHP applications because the high temperature gas turbine exhaust can either be used to generate high pressure steam or used directly for heating or drying.
Aug 06, 2011 · The electrical generating efficiency of standard steam turbine power plants varies from a high of 37% HHV4 for large, electric utility plants designed for the highest practical annual capacity factor, to under 10% HHV for small, simple plants which make electricity as a byproduct of delivering steam to processes or district heating systems.
As water passes through the coil, the heat is transferred from the hot gases which causes the water to convert to steam. The generator design does not utilize a steam drum where the steam of a boiler has a disengagement area from the water in so the use of a steam/water separator to achieve 99.5% steam quality is required.
