Eachsteam and water drum is provided in My invention relates to Water-tube boilers, its rear portion with a transverse separatingand more particularly to the boiler of my partition 18, preferably having an upper pending application, Serial No. '27 8, 88, filed September 1.4, 1905.
The present application relates to certain improved features, more especially the providing of a rear circulation which passes through the diaphragm and in providing an adjustable throttle device for the hole in the diaphragm through which the water circulation passes.
It also consists in an improved arrangement of tube-spacing and in certain combinations hereinafter described and claimed.
In the drawing, 2 represents the upper longitudin aldrum, and 8 the shorter longitudinal mud-drum, which is below and parallel to the upper drum. The upper drum extends over the combustion-chamber, which is shown as provided with grates 4, extending between the bridge-wall 5 and the front wall 6. The mud-drum extends from the rear wall 7 to the bridge-wall 5. That portion of the up-- per drum which is above the mud-drum, is connected therewith by sets of tubes 8, 9,. and 10. These tubes may be of any desirable size and may be connected into' thedrums either by curving their ends. or by using straight tubes with struck-up tubeseats in the drums. The three sets of tubes by the baffles 11 and 12, the baliie 11 extending HPWiLltlY between the tubes 8 and 9, while the baffle 12 extends downwardly between the tubes 9 and 10. The gases are thus given three up and down passes after they pass the bridge-wall before they reach the outlet-flue 13.
The roof of the combustion-chamber is preferably formed of tiles .or refractory bricks 1.4, which lie upon a series of bent tubes 15, extending from front transverse drum or chamber 16 upwardly and rear- 10 (ti/[whom it may concern:
low the water-level. The hole 20 is preferably provided with an adjustable cover or valve device 21, which is hinged and clamped to the partition by the nut and bolt 22. By entering the drum this closure can beset at any desirable point ,WliiCll will depend on the other factors. If bad Water is used, the closure should be arranged to partly close the hole, while if good water is used the holemay be left of greater area. The boiler may thus be adjusted for different localities using different kinds of water. The partition 18 is preferably in line with the baffle'12.v The tubes 9 are heated more highly than the tubes 10, and'consequently there is a circulation up through some of the tubes 9, back through the hole 20, and down through the tubes 10.- The feed-water preferably enters the rear chamber of the upper drum through pipe 23 and overflow-pan 24.
In order to provide for easy removal and replacing of the tubes, 1 preferably arrange them as shownin Fig. 2. c (1 representing the center line of the drum, I arrange the tubes in transverse rows, of which 1 have shown'fou-r to being staggered relative ,to' those on the other side. Thus the tubes 1) of the first row on one side are in line with the space between the two rows of tubes 0 and d on the opposite side. The lateral space between the adjacentrows is greater than the external diame-' ter of the tube, so that the innermost tube 1) may be taken out by passing it between the rows of tubes 0 and d, as indicated by the arrow. Similarly the innermost tube cl may be passed out between the rows of tubes 1) and e, as indicated by the arrow. These insteamhole 19 and a lower hole 20 at or be-' character of the water used and perhaps on each row, the rows onone side nermost tubes of the rows are th e most diflicultto remove, and by arranging" the rows in this peculiar manner I am enabled to cut out and replace them without removing any other tubes.
The advantages of my invention result from the water-circulating hole in the partition-With the adjustable closure, also from the partition in line with the battle in the combination, and, further, from the arrangement of the tube-spacing. I
Variations may be made in the form. and arrangement of the parts without departing from my invention.
I cl aini 1. In a longitudinal drum, water tube boiler, a steam and water drum having a transverse partition with an opening at or below the watenline, and means for varying the area of said opening; sul.)stantially as described.
2. In a longitudinal drum water-tube boiler, an upper drum, having a transverse partition with a steam-opening in its upper part, and a water-opening in its lower part, and an adjustable closure for the water-opening; substantiallyas described.
