44 VAPOBIZING OF PARAFFIN. the faet that the total volume of mixture is drawn through a large exhaust heated chamber, such as shown in the sectional elevation (Fig. 36). In this vaporizer, which works efficiently with any of the refined flash- proof lamp oils, the mixture is only heated to the com- paratively low temperature of 300° to 400° F., in which 2/2 connéction it is well to understand that the more per- t t.-c feetly an oil is atomized the lower is the temperature necessary for its combustion, which is an advantage, Fig. 36.—Exhaust-Heated Vaporizer with Compressed-Air Jet Atomizer. | if not off-set by the necessity for a more than corre- sponding complexity of apparatus, which in this case, as will be seen, requires^an air pump and for the fuel to be contained in a tank subject to a pressure of 8 to 15 Ibs. per square inch ; and this again obviously neces- sitates^ a separate hånd pump, or a pressure supply for starting. For this and other reasons, single- and double- cylinder engines on this system have not been able to
