Fuel oil

“ The very best of our engineering talent have been so successfully concerned with this problem that fuel oil is now used in nearly every steam plant on land and sea, for both stationary and locomotive use. Petroleum-enriched water gas is much superior in cost and quality to the illuminant it is displacing, and now requires considerable oil. Smelting with oil will soon be an accomplished fact in spite of many difficulties, and oil engines such as the Diesel also utilize the crude. ”

“ A wealth of inventive effort has been bestowed in the perfection of the burners employed to consume fuel oil. Leaving aside for the moment the principles governing the use of oil in the internal combustion engines of the Diesel or semi-Diesel type, fuel oil used for the production of power is introduced into the furnace in the form of a spray, this being accomplished by atomizing the oil in its passage through a specially designed burner. ”

“ Further, a very decided saving of fuel may be effected by this combination of oil-gas producer with the internal-combustion engine, in place of the boiler and steam-engine, in many places where suitable oil is cheap or plentiful, or where intermittent work is required. On the other hand, more heat may be produced by the direct combustion of liquid fuel with dry steam and air than by converting the oil into gas before using it as a fuel. Oil-gas is a safe, rich, permanent gas made from petroleum oil, and burned with excellent results in the gas-engine cylinder. ”

“ Fuel oil can be taken on board 79 under far cleaner conditions, and at a greatly accelerated rate, than would be possible with coal. There is no arduous manual labour required. Once the hose connections have been made, the fuel oil is pumped on board at the rate of hundreds of tons an hour, and a few hours suffice to re-fuel our largest battleship. But it is when bunkering at sea is required that fuel oil further emphasizes its immense advantages. ”

“ In tropical theaters, a thickened blend of 50 percent gasoline and 50 percent light fuel oil has been reported to give favorable results. Storage qualities are not known, however. Another mixture which has been well recommended in field reports is 15 gallons of gasoline to 5 gallons of diesel fuel oil. Issue gasoline may be used, but locally procured gasolines which contain alcohol are not suitable.
b. Proportion of thickener to fuel. Less thickener is recommended than formerly. A low ratio of thickener gives a thickened fuel with many of the characteristics of liquid fuel. ”

“ But it is on land, as well as on sea, that we find fuel oil rapidly making headway, for, as far back as 1889, hundreds of the Russian locomotives went over to the 83 84 burning of a petroleum residue. This was the first practical application of fuel oil for railway haulage. To-day, nearly 50,000,000 barrels of fuel oil are consumed annually by the various railroads in the United States, and, according to the official figures I have of the total mileage of fuel oil for the past twelve months, the United States oil-burning locomotives did journeys aggregating over 145,000,000 miles. ”

“ Vickers, in bringing their engine to its present state of perfection, have, perforce, had a varied experience with fuel oils—and a considerable one, too,—for they have experimented with oils from all the well-known producing fields, and find that, under their system, practically any fuel oil which can be made to flow may be utilized in their engines—a fact which, in its importance, speaks for itself. ”

“ The United States primarily imports crude oil but also imports petroleum products including finished motor gasoline, aviation fuel, and fuel oil. The United States imported about 15 billion gallons of finished motor gasoline and gasoline-blending components in 2004. ”

“ While the fuel most commonly used is coal, straw and wood, crude oil is often used, the fuel being determined principally by the location of the engine, and by its cost on the job. The matter of fuel should be taken into consideration when the engine is purchased as the different grades demand different fire box and boiler construction. When it is possible to obtain crude oil at a reasonable figure, it certainly should be used in preference to all others as liquid fuel is the most compact, most easily controlled, and efficient of any. ”

“ Petroleum products are also largely utilized in gas manufacture for, (1) the production of “air-gas,” (2) the manufacture of oil-gas, and (3) the enrichment of coal-gas. For heating purposes, the stoves employed are practically kerosene lamps of suitable construction, though gasoline is used as a domestic fuel in the United States. The use of petroleum as liquid fuel is dealt with under Fuel, as is the employment of its products in motors, which has greatly increased the demand for petroleum spirit. ”

“ The fuel that is used will depend upon the type of furnace and the relative prices prevailing for different kinds. Recent developments in oil heating bring this fuel in close competition from the standpoint of economy with coal or coke. Oil is particularly adaptable as a source of fuel in homes in the country since tank trucks can readily deliver oil to the home owner. Improvements in securing the maximum efficiency from all types of fuel are being developed continually ”

“ I know little beyond the fact that the crude oil arrives by pipe from the oilfields by means of several pumping stations and that it is cooked or distilled over furnaces and converted into different grade oils from petrol to heavy fuel oil. ”

“ The English have thoroughly experimented with fuel oil and demonstrated that, used in a Diesel engine, one ton of oil, or 6.8 barrels, does the work of six tons of coal; and the normal price in England is about five dollars per ton for each, although present war prices are nearly double. Burned under boilers three tons of oil equal six tons of coal. ”

“ Residual oil which was hardly fluid at ordinary temperatures has been successfully used in the Diesel and semi-Diesel types of engines, by preheating it before admission to the inlet valves. The enormously increased demand for gasoline has resulted in a great increase of the formerly useless residual oil so that it is possible that the demand for gasoline will make the production of the residual great enough so that it can be seriously considered as a fuel. ”

“ This astatki, or heavy petroleum refuse, is an excellent liquid fuel, and is at least twice as good as ordinary coal for steam-raising purposes. The light lubricating oils, intermediate oils, and kerosene or ordinary lamp oils are all being used at the present time instead of coal-gas in the cylinder of the internal-combustion engine. In some cases the heavier oils are converted into an oil-gas, which, when cooled, is admirably adapted to drive gas-engines. ”

“ As used at present liquid fuel simply substitutes coal for heating the ordinary type of boiler. But there seems every reason to believe that in the near future some type of internal combustion engine will be perfected that will use the crude, cheap oil, as the finer and lighter oils are used in motors to-day. ”

“ A ship of, say, eight or ten thousand tons, making fourteen knots an hour, could often in fair weather do fifteen knots, but that extra mile an hour would probably cost in coal or oil consumption, $150 or $200 more in the twenty-four hours. Oil makes very little smoke when intelligently "fired." If you want to make a chief-engineer of an oil-burner jump, point out the volume of black smoke coming out of the steamer's smokestacks. He will make for the fire-room and raise Cain. A big volume of smoke shows waste of oil and bad combustion. ”

“ With the discovery and development of the oil wells in the United States about 1860 a new fuel was found in the crude petroleum, as well as a source of light. The application of petroleum to engines, either to produce furnace heat, or as introduced directly into the piston cylinder mixed with inflammable gas to produce flame heat and expansion, has given a wonderful impetus to the utilisation of gas engines. ”

“ Given the one allowance that oil fuel can be procured at anything approaching a reasonable figure—and there is no reason why, in normal times, this reasonable price should not be prevalent all over the world—then petroleum offers many advantages over its older competitor, coal. The ease with which large quantities can be handled, the simple method of operating anything which is fired by petroleum as fuel, and the fact that its heat-giving units are far higher than those of coal, will ever be the chief factors governing its popularity. ”

“ At works using small amounts of fuel, especially if cost of fuel bears but a small proportion to total cost of the manufactured product, oil will be in the future very largely used. It is clean, as compared with coal, can be easily handled, and when carefully used in small quantities, is safe. There are several methods of burning oil that are well adapted to the use of brick manufacturers and other fuel consumers. ”

“ Where petroleum oil can be cheaply obtained, say for twopence per gallon, one of the Otto Cycle Oil Engines, for powers up to 20 indicated horse-power, can be advantageously employed.
These engines have the advantage of being a self-contained power, requiring neither chimney nor steam boiler, and may be said to be a waterless power. The objection is the necessity to rely upon oil as fuel, and the dangers attending the storage of oil. A good oil engine should not require to use more than a pint of refined petroleum per indicated horse-power working for one hour. ”

“ In introducing the oil it is not injected, but is simply allowed to flow in by gravity, at a point about half way up the column of fuel, the taps for its admission being placed at intervals around the circumference of the generator, and oil at first begins to flow down the inside wall of the generator, but being vaporized by the heat, the vapor is borne up by the rush of steam and water gas, and is cracked to a permanent gas in the upper layer of fuel. ”

“ Then too, whatever air may escape contains no fuel, and consequently efficient scavenging may be obtained without waste.
At the high pressure at which the fuel is injected into the cylinder of the Diesel engine, practically any grade of gasoline, naphtha, kerosene, crude oil, or other form of petroleum can be vaporized. The compressed air employed in the compression and injection of the fuel is also used for starting the motor, for this is not a type that is amenable to hand cranking. ”

“ Owing to the enormous cost of handling coal, wood, and other crude fuel, and of removing the ash resulting from such fuel, it has been demonstrated in practice by the use of crude oil that the expense connected with the burning of brick can be reduced fully 60 per cent. This large saving is made by converting crude petroleum into gas and utilizing this fuel, either directly in the arches of the kiln or by converting the crude oil into gas in a gas producer, and drawing this fuel gas from the producer and burning the same as required in kilns of suitable construction. ”

“ It is true that crude oil for brick-burning purposes is not everywhere obtainable. But there is a fuel which is even better than crude oil, namely, fuel gas, and which can be produced and employed on any brick yard at a saving of seventy-five per cent. over coal or other solid fuel. ”

“ For many years, most of the crude oil refined into gasoline in America came from home, came from domestic oil fields. In 1985, 75 percent of the crude oil used in U.S. refineries came from American sources; only about 25 percent came from abroad. Over the past few decades we've seen a dramatic change in our energy equation. American gasoline consumption has increased by about a third, while our crude production has dropped and oil imports have risen dramatically. ”

“ The ease with which oil fuel is handled is remarkable, for vessels of the largest size—that is, those using oil instead of coal for power purposes—could replenish their stores within a few hours at any oil port. In the transport of petroleum by the modern tankers, the taking on board of a full cargo is accomplished in about a single day, thanks to the most improved means of pumping oil from the shore tanks through flexible pipes. ”

“ Diesel Oil Engine. The Diesel engine marks the greatest progress in the internal combustion field made in the last few years. It marks a distinct advance in both thermal efficiency, and in the character of the fuel that it has made a commercial possibility. By the use of cheap fuel heretofore unavailable for any type of prime mover, such as the asphaltum residual oils, coal tar, etc., it has lowered the cost of power production to a point where it is unapproached by any type of heat engine. ”

“ It is the use of gasoline for fuel that makes all this possible. Gasoline, being a very volatile liquid, turns into a highly inflammable gas when heated and mixed with the oxygen in the air. A tank holding from twenty to forty gallons of gasoline is connected, through an automatic regulator which controls the flow of oil, to a burner under the boiler. The burner allows the oil, which turns into gas on coming in contact with its hot surface, to escape through a multitude of small openings and mix with the air, which is supplied from beneath. ”

“ Astral oil and mineral sperm oil are special illuminating oils of high flashing points. Crude petroleum is much used for fuel purposes in engines. Along the Pacific Coast, especially in southern California, where good coal is scarce, the locomotives consume large quantities of crude oil. Paraffin residue is placed on the market for medicinal purposes under the name of vaseline, petroleum ointment, and cosmoline. ”
