PETROLEUM AS PUEL. 
193 
a view of determining the value of Petroleum as a fuel for 
steam-boilers. By a modification of the ordinary furnace, 
substituting steam and oil pipes and burners for the ordi- 
nary bars, the proper combustion of the crude petroleum 
was secured. Though not decisive as to the economy of 
petroleum for use in this manner, to determine which fur- 
ther experiments are necessary, yet this fuel is shown io be 
advantageous as respects the rapidity of getting-up steam, 
reduced loss of heat, reduced dimensions of boiler and fur- 
nace, and freedom from smoke and ash. A very obvious 
feature of the plan tried was the perfect control obtained 
over the fire, which could be reduced or increased with as ' 
much ease as the flame of an ordinary paraffin lamp.
