SECTION THROUGH STOKER
SHOWING MIXING OF GASES
CAUSED BY CURRENTS OF AIR
To sum up, it can be said that the extent of the space required to obtain a combustion which can be considered complete for all practical purposes, depends on the following factors:
(a).—Nature of coal,
(b).—Rate of combustion,
(c).—Supply of air,
(d).—Rate of heating fuel,
(e).—Rate of mixing volatile combustible and air.
Just how much the extent of the combustion space required will be influenced by these factors is the object of the experiments under discussion.
The Scope of the Experiments.—With this object in view, as explained in the preceding paragraphs, the following series of experiments are planned:
