This document discusses improving boiler efficiency at a sugar mill by reducing the moisture content of bagasse through drying. It begins with background on bagasse being used as fuel in sugar mills and how its high moisture content (around 50%) reduces boiler efficiency. The objective is to design and test a bagasse dryer to lower moisture levels and thereby increase gross calorific value and boiler efficiency. It describes the drying process and kinetics, presents design data from a sugar mill, and outlines the methodology which includes building and testing a bagasse dryer model. Testing showed moisture reduction of 10-15% through drying, increasing bagasse calorific value and improving boiler efficiency from 69% to 81%. The conclusion is that the aims of reducing
