ELECTRICITY PRODUCTION

RYAN AND CHETTA (CJ)

Can you imagine your life

without electricity?

Americans call the night of July 13, 1977 "Night of fear." Then there was a huge in size and consequences of the accident at the power

grids in New York. Due to lightning and power line in 25 hours 9 million New Yorkers turned out to be without electricity. Tragedy of the financial crisis was accompanied by unusually hot weather and

the unprecedented wave of crime. After a power outage on the fashionable quarters of the city attacked the gang from poor

neighborhoods.

It was after those terrible events in New York, the term "blackout" has become a commonly used in relation to accidents in the power industry.

Already in ancient times the fire was an indispensable source of heat, light,

human, means for cooking, hunting tool.

Modern community is increasingly dependent on electricity as well as heat. Accidents on the electricity and heating systems applied to tangible losses to enterprises, governments and the public.

We can not imagine myself now without technical equipment you

use, whether it is production, vehicles, information or life.

Since that time, the development of technical ideas allowed to reach a new level

of human life.

WHAT PRODUCES OUR ELECTRICITY?

COAL PLANTS

• Coal Plants produce 44% of our electricity.

• A typical (500 megawatt) coal plant burns 1.4 million tons of coal each year.

• As of 2012, there are 572 operational coal plants in the U.S. with an average capacity of 547 megawatts.

The engine room installed power boilers. They produces steam for the turbines.

During the combustion of fuel in the water tubes, arranged inside the boiler is heated to the boiling point and is converted into steam.

The power boiler comprises of the plurality of pipelines,

auxiliary devices and mechanisms.

Boiler drum. It resultant vapor is separated from the water and heated to the desired

temperature.

Boiler furnace, which burns fuel supplied to the boiler.

Pipelines station - is "artery" of the station, which connect its equipment together.

Pipelines steam enters the power boiler of the steam turbine.

Flue gases from fuel combustion, cooled through the chimney smoke exhausters

removed to the atmosphere.

I had the unique opportunity to visit the

Arkhangelsk cogeneration plant ...

... and see the process of production of electricity and

heat myself.

The paper used CHP fossil fuel energy. It is produced by burning

natural gas and fuel oil.

All pipelines in the territory of CHP are yellow

HYDRO PLANTS (NIAGARA FALLS) Hydroelectricity is

the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy, accounting for 16 percent of global electricity generation – 3,427 terawatt-hours of electricity production in 2010, and is expected to increase about 3.1% each year for the next 25 years.

Treatment - is the processing of water from a natural source, to bring it into

conformity with the quality requirements of the process.

Pipelines station - is "artery" of the station, which connect its equipment together. Pipelines steam

enters the power boiler of the steam turbine.

WIND TURBINES• A wind turbine is a device that converts kinetic

energy from the wind into electrical power.

• The smallest turbines are used for applications such as battery charging for auxiliary power for boats or other smaller things.

• Bigger wind turbines can be used to create large amounts of electricity that can be sold to electrical companies.

• Many countries are now creating wind farms to allow less fossil fuels in the air.

The windmill above is located at Holy Name High School in Worcester Mass.

SOLAR POWERSolar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photovoltaic effect. The PV industry is beginning to adopt levelized cost of energy (LCOE) as the unit of cost. For a 10 MW plant in Phoenix, AZ, the LCOE is estimated at $0.15 to 0.22/kWh in 2005.[

I've always wondered, where there is electricity in our house?Who is responsible for ensuring that the apartments, schools, hospitals was always

warm?

It turned out that our city is the main producer of electricity and heat - Arkhangelsk HPP.

HOW DOES IT GET TO OUR HOMES?

• ELECTRICITY IS TRANSPORTED TO A DISTRIBUTION CENTER

Power line - one of the components of the power system for transmitting electricity, consisting of wires and auxiliary devices for transmission and distribution of power between

consumers.

Transformer - a device adapted to raise the voltage of the electric

current to reduce the losses in power lines.

After the generation of electric power from an

electric transformer

flagged.

THEN THE ELECTRICITY TRAVELS TO OUR HOMES

VOLTAGES

• HERE WE USE 120 –240 VOLTS TO POWER OUR HOUSES

• BUSINESS BUILDINGS USE 277-480 VOLTS OR 208/120 VOLTS

RECEPTACLES (PLUGS)

• OUR RECEPTACLES ARE DIFFERENT FROM YOURS

• IF WE WERE TO COME THERE WE WOULD USE AN ADAPTER

Every year on the last Saturday in March, millions of people around the world turning off the lights for an hour. This action - a symbol of our respect for the home planet, it is designed to draw attention to the unsustainable use of

natural resources and environmental problems

Energy gives us light and heat. And more in the development of mankind advances, the more energy it needs.

However, very often people do not think about what fuels that are used for energy (gas, oil, coal) are irreplaceable natural

resources, which are slowly but surely come to an end.

Each of us needs to understand how important it is to conserve energy and use energy saving simple rules in your home.

0.5 kg of coal

The most efficient way to use energy - just learn how to protect it.

When saving 1 kW/h we saved:

0.4m ³ of gas

0.3 liters of oil
