Furnace Technology Ingress of cold air in the furnaces through cracks, charging doors, openings etc. Reduces the flue gas temperature and makes the furnace atmosphere oxidising Increases the load on the induced draft fan Reduces the furnace draught All of these Reduces the flue gas temperature and makes the furnace atmosphere oxidising Increases the load on the induced draft fan Reduces the furnace draught All of these ANSWER DOWNLOAD EXAMIANS APP
Furnace Technology Metallic recuperators are not used for waste heat recovery, if the hot flue gas temperature is above __________ °C, because corrosion prevails at higher temperatures. 350 750 1250 1050 350 750 1250 1050 ANSWER DOWNLOAD EXAMIANS APP
Furnace Technology In a furnace employing forced draught as compared to induced draught, The fan operates hot and hence blades are liable to corrosion and erosion Positive pressure exists in the furnace Air is sucked in, so air leaks are more and hence the furnace efficiency is reduced None of these The fan operates hot and hence blades are liable to corrosion and erosion Positive pressure exists in the furnace Air is sucked in, so air leaks are more and hence the furnace efficiency is reduced None of these ANSWER DOWNLOAD EXAMIANS APP
