GALLOWAY, of Lambeth, whose improvements in tubular boilers we recently described, has since patented a method of admitting air to furnaces by a pipe or pipes under the furnace bars, into the bridge, and through the top of the bridge into the fire, by a moveable metal mouthpiece or valve. Fig. 1 of the engravings on the preceding page is a sectional elevation, and fig. 2 a longitudinal section of a Cornish boiler, having a furnace constructed according to the invention. A is the boiler, and B the firegrate. C is the air tube, which is formed by placing a plate of iron, D, a few inches above the bottom of the ashpit, and extending the whole length and breadth of it. This plate is air tight at the sides and bridge end, and forms the bottom of the ashpit, on which the ashes, &c., fall from the firegrate. E E' is the bridge, which is made hollow, as shown in fig. 2, the front part, E, or that which is nearest the fire, being built perpendicular, and the back part, E', at an angle, leaving a hollow space, F, between them, which forms a continuation of the air tube, C, and is of sufficient dimensions to admit of the movement of the parts by which the mouthpiece or valve is worked, as hereinafter mentioned. G is the mouthpiece or valve, which is of an angular form, and is supported on two or more hooks, H, built into the brickwork of the back part, E', of the bridge. I is a lever, fixed to the mouthpiece, G, and J is a rod, with a handle, under the control of the engineman, connected to the lever, I, and by means of which the mouthpiece or valve, G, can be brought to any desired position, so as to close wholly or partially the outlet from the hollow of the bridge, as may be required. The rod, J, is formed with a rack near its outer end, to enable it to be held by the catch, K, in any position to which it may have been moved. The arrangement described is also applicable to other forms of boilers, where the contraction of the space over the firebridge is not considered; but in cases where sufficient room is required for a man to pass over the bridge, the inventor forms a portion of the front of the bridge of metal, and attaches it to the fixed part of the bridge, so that it may be readily removable; the valve then works against the top edge of this metal part, instead of against the corner of the firelamp at the top of the bridge. Fig. 3 is a sectional elevation, and fig. 4 a longitudinal section of a still, copper, or boiler, having a furnace constructed according to this arrangement. Figs. 5, 6, and 7 are respectively a front elevation, a cross section, and a plan of the mouthpiece, which is fitted to the front of the bridge, detached; and figs. 8 and 9 are a back elevation and a cross section of the valve, detached. A is the copper, still, or boiler, and B the firegrate. C is the air-tube, and E E' the bridge, as before described. F is the mouthpiece, which is fitted to the front part of the bridge, E, and supported in position by the projecting piece, a a, and the end pieces, bb, which latter come against the sides of the furnace. G is the valve, which is supported by the hooks, H, built into the brickwork of the back part of the bridge, E', and is worked by the rod and lever, J I, as in the arrangement before described. The lever, I, is secured to the valve by bolts, c, and a flap, d, is fixed to the back of the valve, to prevent ashes, &c., from choking it. By removing the mouthpiece, F, and unscrewing the bolts, c, so as to free the valve, and then lifting out the valve, ample space will be given above the firebridge. In the arrangements described, the air admitted to the furnace through the tube, C, is entirely independent of that passing to the fire through the ashpit; and hence the power of the chimney draught will not be diminished, whatever may be the position of the valve, G. The air admitted through the hollow bridge is also to be heated in its passage by impinging against the front part, E, of the bridge, which is exposed to the full heat of the fire. The advantage of the valve at the top of the bridge is, that it controls the force and quantity of the air admitted by it. In no two furnaces will the draught be the same; when the draught is very sharp, the valve requires to be only slightly open; for if open too much, the quantity of air passing cools the brickwork below the required temperature, and it will not then combine with the combustible gases. When the draught is slow, the valve requires to be opened a greater distance to obtain the proper quantity of air, which then passes in with less speed, and does not cool the brickwork so quickly; in either case the valve is not required to be open longer than two or three minutes to bring the furnace to the proper condition. |
