    Pulverised Coal Combustion With Higher Efficiency

    Pulverised coal power plants account for about 97% of the worlds coal-fired capacity. The conventional types of this technology have an efficiency of around 35%. For a higher efficiency of the technology supercritical and ultra-supercritical coal-fired technologies have been developed. These technologies can combust pulverised coal and produce steam at higher temperatures and under a higher pressure, so that an efficiency level of
