Gas Boilers: A Quick Guide | Boiler Advice | Ideal Heating

Put simply, a gas boiler heats up water. It does this by pumping the circulated water in pipework over a series of gas flames. As the water passes the flames, it is heated up, just like water in a pan or kettle. This water serves two purposes in the modern home: central heating and providing hot water.

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Coal Power - Eskom

Due to the heat in the boiler, the coal particles combust and burn to generate heat to turn water into steam. The steam from the boilers is used to turn the blades of a giant fan or propeller, called a turbine. The turbine turns a coil made of copper wire (the rotor) inside a magnet (the stator). Together they make up the generator.

Coal utilization - Coal combustion | Britannica

Pulverized coal can be mixed with water and made into a slurry, which can be handled like a liquid fuel and burned in a boiler designed to burn oil. Coal-water slurry fuel (CWSF) normally consists of 50–70 percent pulverized or micronized coal, 29–49 percent water, and less than 1 percent chemicals to disperse the coal particles in the water and prevent settling of the coal.
