  • What coal is used as major fuel in thermal power plant

    Generally coal is used as a major fuel in mostly all the thermal power plants because it's the most abundant fossil fuel, easily available at relatively low cost. For electric power generation; lignite coal is generally used. Bituminous coal is also used sometimes depending upon the availability.

  • COAL BASED THERMAL POWER PLANTS: COAL MILLS FOR

    Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only two-thirds of the ball mills. However if the primary air fan power is also taken into account, in the case of a pressurized mill the power consumption is lower only by about 15%.

  • Coal Mill an overview | ScienceDirect Topics

    In coal milling for power stations, a ‘closed-loop’ process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system. The situation is further complicated by the ‘mill reject
