Well when I hear the word "Fired" used in reference to a boiler, it is used to describe the type of fuel used to heat the boiler (to fire it) such as a "Coal fired" or "Gas fired"
A boiler in a coal power station is responsible for converting water into steam. The coal is burned in the furnace of the boiler, producing heat which is used to generate steam. This steam is then used to drive a turbine, which spins a generator to produce electricity.
Yes, wood can be burned in coal-fired boilers, provided that the boiler is designed to handle multiple types of fuel. However, using wood can impact the boiler's efficiency and emissions profile differently compared to coal, so it is important to consult with a professional to ensure safe and effective operation.
Coal is burned in the firebox of the boiler to heat the water to steam which then turns the turbines which are connected to the generators which produce the electricity.
A tangentially fired boiler has between 4 and 8 burners, placed in the corners of the boiler. These are sometimes angled vertically to maximize impingement of the flames. They are fired into the center of the boiler, not directly into the center, but at the wall to adjacent to them. This causes the flames to swirl inside of the boiler, causing an even distribution of flame throughout the boiler. This is shown pretty well here: http://www.alstom.com/power/coal-oil/utility-boilers/firing-systems This website also has a lot more detail than previously provided.
Beside small power producer, coal is widely use in cement and paper industry. SCG (Siam Cement Group) is one of the large company utilizing and commercializing of coal in Thailand. However, there are many more company utilizing coal fire boiler and not limited to only the SCG.
For getting better efficiency from boiler, coal is pulverized in mills (powder form) before entering into boiler along with hot air. This is done in order to control damage to boiler tubes and plates due to high (but cheap) sulphur content in coal. These types of boiler are usually called super critical boiler and works on high pressure (3600psi) and temperature (610 degree C) unlike sub critical boilers. alok bh.

Energy cannot be 'made' or 'destroyed'. It can simply be transformed to a different type of energy. Coal contains chemical energy, which will for example, be converted to heat energy in say a coal fired industrial boiler.
Yes, coal is burned in a boiler to produce high-pressure steam, which then spins a turbine connected to a generator to produce electricity. The heat energy from burning coal is converted into mechanical energy and then into electrical energy in the process.
Actually it ran on steam. It had it's own coal/wood fired boiler. I'm not to sure about the date but were talking in the 1700's
