What is a 2X1 power plant?

The most common type of combined cycle power plant utilizes gas turbines and is called a combined cycle gas turbine (CCGT) plant. … For example, at a plant in a 2×1 configuration, two GT/HRSG trains supply to one steam turbine; likewise there can be 1×1, 3×1 or 4×1 arrangements.

What is meant by combined cycle power plant?

A combined-cycle power plant uses both a gas and a steam turbine together to produce up to 50% more electricity from the same fuel than a traditional simple-cycle plant. The waste heat from the gas turbine is routed to the nearby steam turbine, which generates extra power. Tour a combined cycle power plant.

Why combine power cycle is used as power plant?

Combined-cycle plants can adapt to electricity demand or production needs. This type of plants can operate at full capacity with high demand and can bring its operation capacity down to a 45% partial load. This allows the infrastructure to produce what is necessary, avoiding market imbalances or production surpluses.

What is Ccgt energy?

Combined Cycle Gas Turbines (CCGT)are a form of highly efficient energy generation technology that combines a gas-fired turbine with a steam turbine. … The technology is typically powered using natural gas, but it can also be fueled using coal, biomass and even solar power as part of solar combined cycle plants.

How does a SSS clutch work?

The SSS clutch is a freewheel-type, overrunning clutch which transmits torque through concentric surface-hardened gear teeth. … The clutch completes its engagement when the sliding component moves axially against an end stop, and then full torque passes through the helical splines and the fully engaged clutch teeth.

What is duct firing?

Duct firing, on the other hand requires injection of a fuel, such as natural gas or waste gas downstream of the CT exhaust to increase the temperature and mass flow rate of the exhaust gases. Duct firing allows production of more and/or higher pressure steam in the heat recovery steam generator (HRSG).

What is the function of HRSG?

An HRSG is a kind of heat exchanger that recovers heat from the exhaust gases of a gas turbine to an extreme degree. The heat is recovered in the form of steam which is served as the power source of a power-generating steam turbine.

What is the difference between combined cycle and cogeneration?

1) What is the difference between co-generation and combined-cycle power generation? Co-generations uses waste heat for many different processes, such as space heating or drying. Combined-cycle power generation is a two-cycle electricity generation process that uses the heat from the first cycle to run a second cycle.

What is a co generation plant?

Cogeneration—also known as combined heat and power, distributed generation, or recycled energy—is the simultaneous production of two or more forms of energy from a single fuel source. Cogeneration power plants often operate at 50 to 70 percent higher efficiency rates than single-generation facilities.

What is Curtis turbine?

The Curtis turbine is a compound impulse turbine, the com- pounding being both for pressure and velocity. … This is done by compounding the pressure drop, that is, by using several sets of nozzles, thereby reducing the drop in each set, and reducing the exit velocity of the steam accord- ingly.

How a combined cycle plant works?

In a two-on-one combined cycle system, two combustion turbine generators work in conjunction with two heat-recovery steam generators and a steam turbine generator. … The steam spins an additional turbine generator to produce more electricity. The steam is then condensed back to water and recycled.

Which is the most efficient power plant?

Today we announced that the Chubu Electric Nishi-Nagoya power plant Block-1 – powered by GE’s 7HA gas turbine – has been recognized by GUINNESS WORLD RECORDS™ as the world’s Most efficient combined-cycle power plant, based on achieving 63.08 percent gross efficiency.

What is CCGT and OCGT?

There are two types of gas-fired power plants, viz. open-cycle gas turbine (OCGT) plants and combined-cycle gas turbine (CCGT) plants. OCGT plants consist of a single compressor/gas- turbine that is connected to an electricity generator via a shaft.

How long does it take to build a CCGT?

The construction time lag (measured from the moment of the actual start of construction) is five years in the case of nuclear, four years in the case of coal, and only two years in the case of the CCGT plant.

Is CCGT green?

Making electricity green: CCGT power stations and CHP stations. … Additionally, CCGT power stations are much cheaper than some other methods of electricity generation. They cost around 50% less than a comparable coal-fired power plant and can be built in a short space of time.

What is the difference between HRSG and boiler?

Most of the HRSG’s are internally insulated so that expansion does not affect the external surfaces and the structures. Conventional boilers on the other hand are top supported and free to expand so the insulation is on the outside.

What are the types of duct?

Ducts can be made out of the following materials:

  • Galvanized steel. …
  • Aluminium (Al) …
  • Polyurethane and phenolic insulation panels (pre-insulated air ducts) …
  • Fiberglass duct board (preinsulated non-metallic ductwork) …
  • Flexible ducting. …
  • Fabric ducting. …
  • PVC low-profile ducting. …
  • Waterproofing.

Are fire dampers required in 30 minute walls?

Ductwork passing through compartment and sub-compartment walls should be provided with fire dampers. … Where a duct passes through a fire hazard room, but does not serve it, fire dampers are not required but the duct must have fire resistance of 30 minutes in respect to integrity and insulation.

How does a Herzig work?

At the Herzig Eye Institute, our IntraLase® method is a 100% blade-free approach to creating a corneal flap. … The surgeon then lifts the flap where these bubbles have created a smooth surface, and then uses the computer-guided excimer laser to precisely reshape the cornea for corrected vision.

What is HRSG efficiency?

The HRSG forms a major part of the steam system. In the combined cycle mode, the efficiency of the combined gas turbine-plus-HRSG system can reach 55–60% (lower heating value basis) with modern advanced machines, while in cogeneration mode, the system efficiency can be as high as 75–85%.

How tall is a HRSG?

130 feet tall At 130 feet tall, and weighing in at 4,000 tons, the heat recovery steam generator (HRSG) traveled from the Port of Coeymans in Ravena, NY down the Hudson to a new power plant in Sewaren, New Jersey.

What is cogeneration cycle?

Figure 1: A cogeneration cycle makes use of the waste heat generated by a thermodynamic process in order to heat homes, cars, and other appliances. Cogeneration or combined heat and power (CHP) is the on-site generation of electricity from waste heat. The remainder of the energy is lost as waste heat. …

What is cogeneration and how does it work?

Cogeneration, also known as combined heat and power (CHP), is the simultaneous production of multiple forms of energy from a single fuel source 1. … Some trigeneration applications produce electricity and recover heat while simultaneously utilizing the carbon dioxide (CO2) from the exhaust.

What is a combined cycle thermodynamics?

The name “combined cycle” refers to the two thermodynamic cycles that produce power. The most efficient combustion turbines might have a net efficiency of approximately 40%. However, using exhaust heat to generate steam for power raises the overall net efficiency of the plant significantly.
