Steam Boilers, Engines, Nozzles and Turbines Gradually increasing temperature of flue gases at inlet to chimney for given steam outputs is an indication of High calorific value coal being burnt Higher effectiveness of boiler Fouling of heat transfer surfaces Raising of steam temperature High calorific value coal being burnt Higher effectiveness of boiler Fouling of heat transfer surfaces Raising of steam temperature ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines Which of the following is correct? (Where pa = Actual mean effective pressure, pm = Theoretical mean effective pressure, and K = Diagram factor) pa = pm/K pa = K/pm pa = pm + K pa = pm × K pa = pm/K pa = K/pm pa = pm + K pa = pm × K ANSWER DOWNLOAD EXAMIANS APP
