For Fuel and Power).
In Roman times, and until 1900, however, owing to lack of fuel, the smelting was done on the mainland.
The glass industry began in Wheeling in 1821, and there a process was discovered by which in 1864 for soda ash bicarbonate of lime was substituted, and a lime glass was made which was as fine as lead glass; other factors contributing to the localization of the manufacture of glass here are the fine glass sand obtained in the state and the plentiful supply of natural gas for fuel Transportation and Commerce.
With closed stoves much less heat is wasted, and consequ;ntly less fuel is burned, than with open grates, but they often cause an unpleasant sensation of dryness in the air, and the products of combustion also escape to some extent, rendering this method of heating not only unpleasant but sometimes even dangerous.
The system is economical in fuel, but needs skilled attendance to keep the appliances and fittings in order.
In the choice of a boiler of this description it should be remembered that rapid heating, economical combustion of fuel, and facilities for cleaning, are requisites, the absence of any of which considerably lowers the efficiency of the apparatus.
In this primeval, or rather timeless because ever-proceeding, sacrifice, time itself, in the shape of its unit the year, is made to take its part, inasmuch as the three seasons - spring, summer and autumn - of which it consists, constitute the ghee (clarified butter), the offering-fuel and the oblation respectively.
The cotton-wood timber, though soft and perishable, is of value in its prairie habitats, where it is frequently the only available wood either for carpentry or fuel; it has been planted to a considerable extent in some parts of Europe, but in England a form of this species known as P. monilifera is generally preferred from its larger and more rapid growth.
Here again both capital and labour are short, and the cultivation of the soil suffers from the fact that, owing to the absence of timber, dry dung is used for fuel instead of being employed as manure.
The Ural industry is the older, and is still conducted on primitive methods, wood being largely used for fuel, and the ore and metals being transported by water down the Kama and other rivers.
- The maximum power which can be developed by a locomotive depends upon the maximum rate of fuel combustion which can be maintained per square foot of grate.
A tender, however, is so much dead-weight to be hauled, whilst the weight of the water and fuel in a tank engine contributes largely to the production of adhesion.
These are generally tank engines, carrying their fuel and water on the engine proper.
Holden developed the use of liquid fuel on the Great Eastern railway to a point beyond the experimental stage, and used it instead of coal with the engines running the heavy express traffic of the line, its continued use depending merely upon the relative market price of coal and oil.
(Fuel.) (WinterCotton seed yellow stearin.) (Cattle food) with the meal.
Fuel oil is submitted to certain of the foregoing tests and in addition the calorimetric value is determined.
The total exports of the Cardiff docks in 1906 amounted to 8,767,502 tons, of which 8, 433, 629 tons were coal, coke and patent fuel, 151,912 were iron and steel and their manufactures, and 181,076 tons of general merchandise.
Jn 1841 natural gas was found with salt brine in a well on the Kanawha, and was used as a fuel to evaporate the salt water.
Pig iron is manufactured cheaply because of the low price of fuel; in 1907 the value of pig iron manufactured in the state was $6,454,000.
The typically industrial region of France is the department of Nord, the seat of the woollen industry, but also prominently concerned in other textile industries, in metal working, and in a variety of other manufactures, fuel for which is supplied by its coal-fields.
Attempts have frequently been made to use the mineral for ordinary fuel purposes, but its inferior quality has prevented its general use.
Coal takes, however, an altogether secondary place as a fuel in Russia; wood is much more extensively used, not only for domestic, but also for industrial purposes.
At the same time large quantities of petroleum refuse are used as fuel in the railways of S.E.
The Rocket possessed the three elements of efficiency of the modern locomotive - the internal water-surrounded fire-box and the multitubular flue in the boiler; the blast-pipe, by which the steam after doing its work in the cylinders was exhausted up the chimney, and thus served to increase the draught and promote the rapid combustion of the fuel; and the direct connexion of the steam cylinders, one on each side of the engine, with the two driving wheels mounted on one axle.
- The resistance against which a train is moved along a railway is overcome by means of energy obtained from the combustion of fuel, or in some few cases by energy obtained from a waterfall.
Peat is largely used as fuel, coal being obtained only at a cost of £3 a ton.
Even if the sun were made of one mass of fuel as efficient as coal, that mass must be entirely expended in a few thousand years if the present rate of radiation was to be sustained.
That vigorous chemical action is accompanied by a brisk evolution of heat is evident from such familiar examples as the combustion of fuel or the explosion of gunpowder.
Besides the petroleum refineries the town possesses oil-works (for fuel), flour-mills, sulphuric acid works and tobacco factories.
The wood is burned for fuel, its heat-giving power being reckoned in Germany about one-fourth less than that of beech.
For a long time these shells or hulls, as they are called, were burned at oil mills for fuel, 22 tons being held equal to a cord of wood, and 43 tons to a ton of coal.
Here was material enough for an explosion, even if personal misunderstandings and aggravations, adding fuel to the fire, had not naturally occurred (or even been deliberately plotted) during the negotiations.
There are also in the city several large grain mills and breweries, a biscuit factory, wire and hemp roperies, fuel works, general foundries and engineering works.
The gas is excellent, is used for lighting the town, supplies light and fuel for the people, and a number of industries are using the gas for manufacturing.
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.
