BAGASSE AS FUEL

all the way from 5-45 to 7-95 grams, and the following observations were 

 drawn. 



1. A denser bagasse was of superior fuel value. 



2. A denser bagasse was generally rich in cellulose. 



3. Canes with most fibre give a bagasse of superior fuel value. 



These observations tend to connect the mechanical structure of the 

 bagasse with fuel value, for it is not unreasonable to suppose that a grate

area sufficient for a dense bagasse may be too small for that afforded by 

 another type, and the solution of the trouble would be in the installation of 

 auxiliary grate area. 



In addition, the trouble may be due to a combination of all the causes 

 tending towards low thermal value : 



1. A fibre with the lower limit of the recorded heat of combustion. 



2. A fibre which retains after crushing a higher quantity of water. 



3. A lower percentage of fibre in the cane.
