Аннотация: The coal?fired power generation efficiency and minimization of loss of fuel energy for low-rank coal is essentially integrated to pulveriser performance. In this book, the merit of proposed concept of PFGR© arrangement has been established on the fact that, drying capacity of the milling system of a sub-critical PC fired power plant may be enhanced from rated allowable maximum gross raw coal moisture drying to higher percentage low-rank raw coal moisture drying without compromising the coal throughput capacity of the milling system while a fuel switching is done from mill selection coal having a gross coal ash-moisture less than gross ash- moisture of available low-rank coal. The present study has been established on the fact that there is a tangible reduction in above referred low-rank coal consumption and reduction in equivalent CO2 emission along a steam cycle heat rate incentive and simultaneously a substantial amount of boiler exhaust waste heat energy is recovered per kg of coal dried when this proposed plant performance improvement model is adopted for a sub-critical PC fired Rankine steam cycle plant with integrated drying and partial coal devolatilisation arrangement.
