The Pennsylvania Railroad made some very thorough experiments on the use of petroleum in their locomotives, and while the results obtained are reported to have been satisfactory, it was the opinion of those having the experiments in charge that the demand for the Pennsylvania Railroad alone, were it to change its locomotives from coal to oil, would consume all the surplus and send up the price of oil to a figure that would compel a return to coal.
It is true that production has enormously increased in the last three years, and the promise for the near future is that a high rate will be maintained. It is further true that the production of Russia has increased enormously, and will probably be larger this year than ever before. This Russian oil must go to markets and supply demands that have been met by American oil, and this will still further increase the amount of oil available for fuel purposes.
There is no doubt, therefore, that petroleum has a future for fuel uses. Many brick manufacturers are ready to use it, notwithstanding the possibility of an advance in its cost.
While there are some objections to the use of petroleum as a fuel, growing chiefly out of the risk attending its storage and conveyance to the point of consumption, it is undoubtedly true that the chief objection is the fear that with the increased demand that would follow any extended use for this purpose would come an increase in price that would make its continued use too expensive.
Just four years ago, when the fuel oil industry was first projected, it was cried down because, as its enemies claimed, there was not enough oil fuel to be obtained in America to supply the New York City factories alone, to say nothing of other territory, and because of the high prices for oil that were sure to follow its substitution for coal fuel. Since then the industry has experienced a magnificent success, the sales exceeding 20,000,000 barrels a year, while the price is lower than ever.
A curious impression seems to have gained ground to the effect that the Standard Oil Company does not want to sell oil for fuel. It may be stated authoritatively that the company is not only able but willing to sell and deliver oil for fuel purposes in any quantity that may be desired. It is now delivering oil for fuel purposes in fourteen States of the Union. For its sales in Chicago and the West and Northwest, the delivery is by tank cars from the terminus of the pipe line at South Chicago, to which point it is pumped from Lima, O. The Chicago price is 1-2/3c. per gallon, or 70c. per barrel of 42 gallons, f.o.b. cars at Chicago.
A great many of the brick manufacturers here and throughout the Northwest are beginning to use crude petroleum as a substitute for soft coal. It is smokeless, for the fine spray of oil which comes from the injector consists of such minute drops of the liquid and is so thoroughly mixed with oxygen that when it burns the combustion is complete, and only steam and carbonic acid gas go out of the top of the kiln. Not a speck of soot comes from the kiln or the smokestack or soils the whitewashed purity of the boiler room. Oil fuel is absolutely clean. It is labor saving, too. No fireman has to keep shoveling coal, there are no ashes to be dragged out from under the furnace grates, and there are no clinkers to clog up the bars. One man, by turning a valve, may regulate the heat of a kiln containing one million brick.
Not only is it cleaner than coal and calls for less labor, but it is actually cheaper as a fuel. A barrel and a half of crude oil is equal for furnace fuel to a ton of the best Illinois bituminous coal, and at 70c. a barrel any one can easily calculate the advantages petroleum has over its smoky rival. Theoretically, two barrels of oil equal in heating power one ton of best Pittsburg coal.
An examination into the relative cost of the Pittsburg and Chicago coal to the oil consumed shows that the price of oil at Pittsburg is 59c. per barrel of 42 gallons, and slack coal can be purchased at from 70c. to 80c. per ton, and the best quality of lump coal at from $1.10 to $1.25 per ton, while the same quality of fuel can be bought in Chicago at about 70c. a barrel, as against coal at from $2 to $3.50 per ton. It would, therefore, look as though there could be no question whatever as to the economy and advantages to be derived from the use of oil as a fuel in this vicinity.
The weight of oil required is less than half that of average coal to produce the same amount of steam.
