Boiler Efficiency - an overview | ScienceDirect Topics
Coal preparation for pulverized coal (PC) combustion always includes drying, which must be very intensive, especially if moist lignite is used. Lignite pulverization is aided by the presence of hot flue gases (with temperature up to 1000 °C), which are extracted from the boiler through recirculation ducting.
Steam Power Station: Components, Application, and Working
Boilers for Steam Power Plants. The boiler has the capacity to convert water into steam. The process of change of water to vapor is produced by heating the water in the tubes with energy from burning fuel. The combustion process is carried out continuously in the combustion room with fuel and airflow from the surface.
•Affects combustion efficiency and boiler efficiency •Causes clinkering and slagging. Moisture Content: Moisture in coal must be transported, handled and stored. Since it replaces combustible matter, it decreases the heat content per kg of coal. •Increases heat loss, due to evaporation and superheating of vapour
