Molasses as a fuel. Many experiments have been made, using 

 this substance as a sugar-house fuel, and while ordinarily it 

 may be better employed m some other manner, at the same time 

 where no other provision is made for the use of this material, 

 and where there is a scarcity of fuel as well, satisfactory results 

 may be secured in its combustion if it is properly handled. 



Waste molasses consists mainly of gums, sucrose, glucose, 

 albuminoids, other organic compounds, water, and a small amount 

 of ash. 



Sucrose has the chemical formula of carbon 12 (atoms), hy- 

 drogen 22 (atoms), and oxygen 11 (atoms). The burning of 

 carbon consists in uniting oxygen to that element, forming car- 

 bon dioxide. When hydrogen burns, the oxygen combines with 

 it, forming water. During this oxidation, two atoms of hy- 

 drogen combine with one of oxygen, but in the molecule of sugar, 

 these two elements are already present in this proportion, con- 

 sequently only the carbon may be oxidized and thus give off 

 heat. This is found to be true also of sucrose, reducing sugars, 

 and many organic compounds. 



An instrument called a calorimeter is used to determine the
