\ ,dented tant LUTHER R. WALLACE, OF ADRIAN, MICHIGAN.
Letters Patent No. 90,615, dated May 25, 1869.
IMPROVEMENT IN STEAM-BOILER RURNACES.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern:
Be it known that I, LUTHER R. WALLACE, of Adrian, in the county of Lenawee, and State of Michigan, have invented a new and useful Improvement in Furnaces for Steam-Boilers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, which will enable others skilled in the art to make and use my invention, reference being had to the accompanying drawings, and to the letters of reference marked thereon, similar letters referring to like parts.
The nature of my invention consists chiefly in so constructing the dre-furnaces of steam-boilers' that the draught is downward through the fire instead of upward, thereby causing a more perfect combustion of the smoke and fuel, and hence realizing far more heat from/.a given amount of fuel.
To enable others skilled in the art to make and use my' invention, `I will now' proceed to describe its con struction and use.
n In the drawings- Figure 1 represents a longitudinal section, passing l vertically through the centre of a steam-boiler, and also through the centre of my improved furnace attaohed.
Figure 2 represents a transverse section, ,passing vertically through the line X-Y in the previous figure. Figure 3 represents a view of the cover F of the i fire-furnace B.
H represents the boiler.
fff, dto., the dues.
Between the hre-furnace B and the dues, l drop down, from the upper part of the boiler H, 'a partition water-space, A, and produce it below the furnacegrates g, leaving a space between it and the bottom k of the air-space 1.
This partition waterspace A extends the whole width of the fire-furnace, and is hollow, being formed of the same material as tne boiler, and opening into -it so as to be lled with water.
E is a fire-box, and intervenes between the furnace B and the fines of the boiler, and is partially sepa rated from the furnace B by the water-space A, as
shown. in fig. 1 of the drawings.
t'l is an outside water-space, and surrounds the firefurnace and fire-box on their four perpendicular sides, and opens into the water-space in the boiler, as shown in figs. 1 and 2 of the drawings.
n and m, iigs. l and 2, represent two of the sides of a rectangular frame of iron, which forms the bottomv of the outside water-.space t, thus allowing the ashes from the furnace to fall upon the bottom hof the air-space 1.
The grates g are placedl at the bottom of the furnace, after the usual manner, to hold up the fuel.
D is an ash and fire-pit, to receive the ashes and allow they heat and flame to pass from thefurnace B, through the grates g, and down under the water-space A into the fire-box E, and thence .upward into Ithe boiler-dues f f f,- 85o., thereby causing a perfect com- 4 bustion of the fuel, and of the smoke,- in passing through the fire, and not 'allowing anything but heat and ameto enter the fire-box E and ues of the boiler.
The covering F of the fire-furnace B is represented in the third figure of the drawings, and it shows the two doors a and a', for supplying the-furnace with fue), and also the draught-damper S, with openings c c c, and representing, by dotted lines, the water-space p 't and the air-space 1.
The doors areelevated obliquely to an angle of about forty-five degrees from the cover F, so that the fuel may be thrown into the lire-furnace in the direction indicated by the arrows, so as to fall upon any part of the grates g.
This is done by throwing the fuel either against the backs b and b of the door-boxes, and letting it glance off upon the grates g, near tlie back side of the furnace B, or by thro-wiring the fuel diagonally, as represented bythe arrow t, to the front side ofthe furnace.
The fire is kindled upon the grates, in my improved furnace, in the same manner asin other furnaces, and as the coal, or other fuel, is thrown down upon it, it immediately IigniteS, and the smoke passes downward through the fire, where all the unconsuined particles are ignited, and a perfect combustion takes place.
In using coal for fuel, the economy is most markedv in my furnace,l for the draught being downward, the smoke of the coal is drawn through the fire, and conj sumed by a perfect combustion; whereas, by the common upward draught, the smoke passes off without being consumed, and is lost, and thus is wasteda large percentage of the real value f the coal. l
Moreover, the lire inthe furnace, being located between the dues of the boiler and these doors, prevents the direct actiouof the cold air upon the dues when the doors are opened to feed the fire.
'The ash-pit will be provided with the customary opening for the withdrawal of the ashes, to be arranged on either of its sides, as preferred, and provided with a tight door, or other means for closing it.
