The Iron and steel magazine . workwith no intermediate losses as is the case with gas, the valueof oil over the latter is marked. It is difficult to make an actual comparison beteen oiland coal for steel melting on the basis of the cost of a ton ofmetal produced. The figures may be in favor of coal in certainlocalities, and in favor of oil in others. Yet the advantages ofoil over coal in working results are so pronounced that discre-pancies in cost against oil are offset by its usefulness. Ignoring the relative costs, the principal points in favorof oil against gas will be considered: )pen Hearth Steel ( asth 2<)<) First, the higher thermal value. A cubic fool of gas willyield L37 B. T. U. Taking 10,000 B. T. II. as anone pound of oil, and allowing a cubic foot of oil at 57 n-100pounds, then X 16,000 = B. T. U.,a substantialgain in favor of oil against an equal volume of gas. Second, the simplicity of installation. One furnace willrequire a storage tank with a capacity of about 17,000 gallons;. from this the oil is pumped to the burner (see cut) which essen-tially is the producer in the sense that the arrangement of theburner permits a necessary atomization of the oil by steam orcompressed air before ignition. It is superfluous to make afurther comparison on this point, in view of the crudity of thegas producer. Third, the use of oil lessens furnace repair costs andallows longer campaigns before shutting down for general point alone is, perhaps, the strongest one in favor of oil. 3°° The Iron and Steel Magazine Conditions of brick work in regenerator chambers do not requirethe same attention with liquid fuel as they would with is to say, should there be leakages in the partition wall
