Furnace Technology The amount of combustible escaping uncon-sumed from the furnace, depends upon the Air preheat and the flow of gases in the furnace (mixing by induction, by acceleration or by change of direction) All of these Air supplied and furnace temperature Burner design (thoroughness of mixing versus stratification) Air preheat and the flow of gases in the furnace (mixing by induction, by acceleration or by change of direction) All of these Air supplied and furnace temperature Burner design (thoroughness of mixing versus stratification) ANSWER DOWNLOAD EXAMIANS APP
Furnace Technology In a furnace employing forced draught as compared to induced draught, 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 The fan operates hot and hence blades are liable to corrosion and erosion Positive pressure exists in the furnace ANSWER DOWNLOAD EXAMIANS APP
