It was the first power station of its kind, burning enough coal to provide energy to light 1,000 lamps in ...

Coking Wikipedia

Coking Wikipedia

Coking. Coking is the heating of coal in the absence of oxygen to a temperature above 600 °C to drive off the volatile components of the raw coal, leaving a hard, strong, porous material of high carbon content called coke. Coke consists almost entirely of hydrocarbons. The porosity gives it a high surface area, which makes it burn faster (as ...

Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into the water, and returned to the boiler to start the process over. Advantages of Coal Power Plant

How CO2 Scrubbing Works | HowStuffWorks

How CO2 Scrubbing Works | HowStuffWorks

The CO2 Scrubbing Process. CO 2 scrubbing works not by physically scrubbing the coal, but by isolating CO 2 from the other flue gases before they're released into the air.

Why does burning coal generate more CO2 than oil or gas?

Why does burning coal generate more CO2 than oil or gas?

As the fuels burn, oxygen in the air reacts either with carbon, forming CO 2, or with hydrogen, forming H 2 O, or water vapor. When coal burns, its higher proportion of carbon molecules creates more CO 2 per unit of energy. For oil and gas, it's "mainly the hydrogens that will burn and generate energy, not the carbons," Stephanopoulos says.
