How is gas (Carbon Dioxide) produced in a Power Station? For example a Coal-Burning Power Station?

Question

Please can someone explain, thank you.

Answer 1

all things that can be burned contain hydrogen (H) and carbon (C). When they are burned they react with Oxygen (O)in the air to form carbon dioxide and water in complete combustion or water and carbon monoxide in incomplete combustion. (this only happens if there isn't enough oxygen around to for carbon dioxide and water.

take burning methane for example:

complete combustion

O2 + CH4 = 2H20 + CO2  balanced equation

incomplete combustion

2O2 + CH4 =2H20 + C0     balanced equation

Answer 2

Coal-burning power stations extract bond energy from the coal they burn. Most of this bond energy is in carbon molecules. To extract the energy, the high-energy carbon-carbon and carbon-hydrogen bonds have to be converted into low-energy carbon-oxygen bonds. The net result of this is that the carbon in the coal is combined with oxygen from the air to form primarily carbon dioxide.

Answer 3

When fossile fuels like carbon burn in air they release carbondioxide gas.

  C+O2=CO2

Answer 4

A power station produces electricity by spinning a giant electromagnet inside a machine that contains giant coils of insulated wire these wires are taken out from the power station and fed across the country supplying electricity to homes and businesses etc. Steam at high temperature and pressure is used to spin the electromagnet. This steam is produced in a furnace or boiler that is heated by burning coal to generate the heat required to turn water into steam.

Coal is a fossil fuel like oil and contains hydrocarbons (hydrogen and carbon compounds) that burn in the presence of oxygen. When the fuel burns in the boiler a chemical reaction takes place in which the carbon in the coal and the oxygen in the air inside the boiler combine into the gas carbon dioxide. At the same time this chemical reaction releases energy in the form of heat that turns the water into steam that turns the magnet.

    

Answer 5

coal mostly consits of carbon. when coal is burnt the carbon reacts with oxygen in the air and produce carbon dioxide.

C+O2------> CO2

but if there isnt enough oxygen then the reaction would produce carbon monoxide

2C+O2------> 2CO

CO is a pollutant  

Answer 6

Fossil Fuel burn in electricity power station  are the single major source of human-produced CO2, followed by transport and industry.
