The conversion from coal to electricity takes place in three stages. Stage 1 The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2 The second stage is the thermodyna…

In a post-combustion process, CO2 is separated and captured from the flue gases that result from the combustion of fossil fuel. This process is the most commonly used technique in carbon-capture technology. It's a convenient strategy because it can be deployed at both new and preexisting coal-fired power plants.

How Natural Gas Works. Published Jul 15, 2008 Updated May 9, 2023. Natural gas, also known as methane or just "gas," is used in heating, cooking, electricity production, transportation, and as an industrial feedstock. In 2021, it made up 32 percent of the US energy mix, and has grown since. Because gas is a fossil fuel, like oil and coal, it ...

Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity. With more than 400 commercial reactors worldwide, including 93 in the United States, nuclear power ...

The normal yield of coal tar during the coal carbonizing process is around 4 %. Coal tar has a specific gravity normally in the range of 1.12 to 1.20, but exceptionally it can go upto 1.25. It depends on the temperature of carbonization. The lower specific gravity tars are generally produced when low carbonization temperatures are used.
