A. It should be burning brightly and strong enough to prevent the draft
from putting it out when the throttle is opened. And a little smoke
should show up at the stack, which would indicate that the fire was
being forced just a little ahead of the working of the engine.
25. Q. Which is desirable, to use as much or as little steam jet
atomizer as possible?
A. It is desirable to use as little atomizer as will make engine show
perfect combustion and economy.
26. Q. What is the result of too little steam jet atomizer when standing
at stations or when the engine is working light?
A. The result of too little atomizer when standing at station or when
engine is working lightly, will result in the oil not being carried far
enough into the fire-box or arch and not properly atomized and the fire
is liable to go out. The oil will drop from the mouth of the burner into
the draft pan to the ground where it is very liable to start a fire
under the engine.
