Fuels and Combustion Ratio of primary air to secondary air increases with increase in the rank of coal, because the Ratio of fixed carbon to volatile matter increases High rank coals have higher amount of volatile matter Oxygen content progressively decreases Calorific value of the coal increases Ratio of fixed carbon to volatile matter increases High rank coals have higher amount of volatile matter Oxygen content progressively decreases Calorific value of the coal increases ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion Fussain Is friable, charcoal like substance Has highest fixed carbon and lowest volatile matter content of all the four banded components of coal All of these Is non-coking, but when blended with highly coking coal, controls its swelling and produces high strength coke on carbonisation Is friable, charcoal like substance Has highest fixed carbon and lowest volatile matter content of all the four banded components of coal All of these Is non-coking, but when blended with highly coking coal, controls its swelling and produces high strength coke on carbonisation ANSWER DOWNLOAD EXAMIANS APP
