Coal is the cheapest power source but also the dirtiest. Its well-known that China has comparatively lax environmental policies. Major cities like Beijing are notorious for their high levels of smog, produced mostly by burning coal. Energy producers can freely burn coal and use the energy for Bitcoin mining. Read

  • The Steam Engine, the Industrial Revolution and Coal

    This solution was Thomas Newcomen s 1712 invention of a simple single-piston pump, the first machine to successfully direct steam to produce work. Newcomen engines were quickly put to use all over England to pump out the water that regularly flooded the coal mines. Coal Feeder is a device that regulates the amount of coal to be supplied into the Coal Mill. The amount of coal is regulated according to the needs in the boiler combustion chamber (furnace). The number regulation system in the coal feeder can be done in two ways based on the type, namely by weight fraction or coal volume fraction.
