DEVICEFOR FEEDING FINE FUEL.
SPECIFICATION forming partrof Letters Patent No. 238,891, dated March 15, 1881. Application filed December 3, 1880. (No model.)
To all whom 'it may concern:
Beit known that I, AUGUSTUS GEEINEE, of Somerset, in the county of Perry and State of Ohio, have invented a new and Improved Device for Feeding Fille Fuel, of which the following is a full, clear, and exact description.
The object of this invention is to economize in the quantity of fuel used, and to use cheaper fuel for furnaces, forges, &c.
The drawing represen ts a vertical sectional elevation ot' the apparatus for containing the supply of coaldust.
In the drawing, A represents a hollow cylindrical vessel having conical ends c c, and in the upper end a suitable door, B, for the introduction of the coal-dust.
Connected with a central opening. b, in the lower end of the vessel A is a pipe, C, for the admission of the forced current of air or steam into the said vessel A, said pipe O being provided with a suitable regulating valve or cock, D. y
Connected with a central opening, c, in the upper end of the vessel A is apipe, E, for conducting the coal-d ustladen current or jet of air or steam to the furnace or tire for which it is designed.
F represents a quantity of coal-dust in the vessel A.
It is designed to arrange the vessel A between a source of steam or air pressure and the furnace or lire-box to be supplied with fuel, and to make suitable connections therewith. Coal-dust is then introduced into the vessel A through the door B, which latter is afterward tightly closed in order to prevent the escape of air, steam, or coal-dust. A suitable tire is then built in the furnace or tre-boX,and when the walls ot' said furnace or re-box have become heated to some extent the blast of air or jet of superheated steam is applied through the pipe O and opened valve D up through the coa-l dust in the vessel A, and in passing through the vessel A the air or steam column takes up a quantity of the coal-dust F and car- 4 ries it through the pipe E into the heated furnace or re-box, wherein it is ignited by the tire there and burned with a rapidity and intensity proportioned to the degree ofineness to which it (the said coal-dust) is reduced. If the coal be very finely comminuted it will take re in the furnace or fire-box and burn like a jet of gas, and if the coal be introduced into the furnace by ajet of steam the steam will be decomposed by the incandescent floating particles of cai-bon, and thereby supply .additional oxygen to thecarbon, and also furnish hydrogen for combustion.
With a continuous supply of air or steam borne dust coal ot' suitable tneness a furnace or're-box will require little or no other fuel after the walls thereof have become thoroughly heated. p
In this process line coals that are otherwise almost useless as fuel canl be used, and such coals can be obtained at much less cost than lthose of ordinary commercial grades; and,
further, it is found that complete combustion is assured with air or steam borne coal of suflcient fineness; hence the combustion of the lfuel is attended with a higher temperature Y than in the usual methods of burning coal, and
is characterized by an entire absence of smoke. Having thus described my invention, I claim as new and desire to secure by Letters Patent- An apparatus for feeding coal-dust to furnaces, consisting of an airtight coal-dust vessel provided at one end with an inlet adapted to be connected with an air or steam supply, and at the other end with an outlet adapt-ed to be connected directly with the furnace, as shown and described.
