Drying bagasse by using flue gas which comes from air preheater to chimney is an optimum solution to enhance efficiency of boiler in sugar factory as bagasse has high calorific value but due to its moisture about 50% not able to use its full heat. The present work suggest to place Cylindrical shell type dryer, in between the air preheater and chimney, and flue gas pass from dryer’s one end and from another end bagasse by carriage, makes dryer to act as a counter flow heat exchanger where flue gas gives its heat at 190°C to the bagasse at 45°C this reduce moisture of bagasse from 50% to 46%, increased CV of bagasse around 784 KJ/kg which increases boiler efficiency from 79% to 81% in sugar industries.
