How fossil fuels are used to generate electricity?
Power plants burn fossil fuels to heat water and make steam, which triggers complex generators inside the plant. These processes create an electromagnetic field that provides the electrical energy that people consume. A number of fossil fuels are used to make electricity, but the most common and inexpensive is coal.

Power plants can make so much energy because they burn huge amounts of fuel—and every single bit of that fuel is packed full of power. Unfortunately, most power plants are not very efficient: in a typical old plant running on coal, only about a third of the energy locked inside the fuel is converted to electricity and the rest is wasted.

How are fossil fuels used to generate electricity?
How Fossil Fuels are Used to Generate Electricity. The world is constantly in need of electricity, as it drives human activities and keeps the world in motion. To cater to practically every need, every year we consume more than 24 PWh of electricity. That is 24,000,000,000,000,000 Wh/year (Longo, 2019).
How much carbon dioxide does burning fossil fuels produce?
The burning of fossil fuels produces around 6.3 billion metric tons of carbon dioxide per year. It is estimated that natural processes of the Earth can only absorb about half of the amount, resulting in a net increase of 3.2 billion tons of atmospheric carbon dioxide per year which may lead to global warming.
How does burning fossil fuels affect the environment?
Another unavoidable consequence of burning any fossil fuel is that the process generates greenhouse gases, mostly Carbon dioxide (CO2) but also Sulphur dioxide (SO2) and Methane (CH4), all of which contribute to global warming. The burning of fossil fuels produces around 6.3 billion metric tons of carbon dioxide per year. It is estimated that natural processes of the Earth can only absorb about half of the amount, resulting in a net increase of 3.2 billion tons of atmospheric carbon dioxide per year which may lead to global warming.

In the United States, fossil fuels supply most of our energy needs, including roughly two-thirds of US electricity generation (UCS, 2019). Even in the UK where clean energy has charted a course for the country’s electricity generation needs, in the third quarter of 2019, some 39 percent of UK electricity generation was from coal, oil, and gas, and staying true to their commitment to clean (or in this case cleaner energy), 38 percent came from natural gas and less than 1 percent from coal and oil combined. (Evans, 2019).
How can a gas turbine be used to achieve high efficiency?
High efficiency can be achieved through the combination of gas and steam turbines in a combined cycle mode. A semi-closed or closed gas turbine may be used where fuel (natural gas in this case) is combusted with oxygen. A gas turbine is a type of continuous combustion engine.
How does the Kingston Fossil Plant work?
A practical example is noted in the Kingston Fossil Plant near Knoxville, Tennessee, which burns coal to heat its boilers to about 1,000 degrees Fahrenheit , thereby creating high-pressure steam. The steam is piped to the turbines at pressures of more than 1,800 pounds per square inch. The turbines are connected to the generators and spin them at 3,600 revolutions per minute to make alternating current (AC) electricity at 20,000 volts. Water is then pumped in a condenser to cool and condense the steam coming out of the turbines. The Kingston plant generates about 10 billion kilowatt-hours a year, enough electricity to supply 700,000 homes. To meet this demand, Kingston burns about 14,000 tons of coal a day (TVA).

How does supplementary firing help a combined cycle power plant?
A flexible stationary plant can make more money. Duct burning raises the flue temperature, which increases the quantity or temperature of the steam (e.g. to 84 bar, 525 degree Celsius). This improves the efficiency of the steam cycle. Supplementary firing lets the plant respond to fluctuations of electrical load, because duct burners can have very good efficiency with partial loads. It can enable higher steam production to compensate for the failure of another unit. Also, coal can be burned in the steam generator as an economical supplementary fuel.

With these limits, a steam plant has a fixed upper efficiency of 35–42%. An open circuit gas turbine cycle has a compressor, a combustor and a turbine. For gas turbines the amount of metal that must withstand the high temperatures and pressures is small, and lower quantities of expensive materials can be used.
How efficient is a combined cycle power station?
The electric efficiency of a combined cycle power station, if calculated as electric energy produced as a percentage of the lower heating value of the fuel consumed, can be over 60% when operating new , i.e. unaged, and at continuous output which are ideal conditions. As with single cycle thermal units, combined cycle units may also deliver low temperature heat energy for industrial processes, district heating and other uses. This is called cogeneration and such power plants are often referred to as a combined heat and power (CHP) plant.
How does a combined gas and steam cycle work?
So, a combined cycle plant has a thermodynamic cycle that operates between the gas-turbine's high firing temperature and the waste heat temperature from the condensers of the steam cycle. This large range means that the Carnot efficiency of the cycle is high. The actual efficiency, while lower than the Carnot efficiency, is still higher than that of either plant on its own.
