I IVENTOR UNITED STATES PATENT OFFICE.
JOHN E. BELL, OF BARBERTON, OHIO, ASSIGNOR TO THE BABCOGK & WILCOX COMPANY, OF
NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.
SUPERHEATER-BOILER.
Specification of Letters Patent.
Patented Dec. 22, 1908.
Application filed December 13, 1904. Serial No. 236,669.
T 0 all whom it may concern:
Be it known that I, JOHN E. BELL, of Barberton, Summit county, Ohio, have invented a new and useful Superheater- Boiler, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure l is a longitudinal, vertical section showing one form of my improved superheater boiler; Figs. 2 and 3 are similar views showing modified forms and Fig. 4 is an elevation of the superheater.
My invention relates to that class of superheater boilers wherein the boiler is provided with upper and lower drums connected by water tubes with the furnace at one side and the gases being given at least one pass among the tubes.
My invention consists in combining with such a boiler, a superheater which the gases enter at their second pass, and which provides the heating surface for the last pass or passes of the gases which enter the outlet flue after leaving the superheater.
The invention also consists in providing in such a construction a superheater of the same general type as the boiler with transverse upper and lower drums connected by superheating tubes.
In the drawings referring to the form of Fig. 1, 2 represents an upper steam and water drum and 3 a mud drum connected by water tubes 1. A battle 5 extends along the back of the water tubes to direct the gases from the furnace 6 upwardly among the tubes. At the rear of the boiler I provide a superheater which in this form consists of an upper transverse steam drum 7 connected to a lower drum 8 by superheating tubes 9. 10 is the baffle along the back of the superheating tubes which causes the gases to flow downwardly among these tubes. The upper superheater drum 7 is preferably provided with a transverse partition dividing it into compartments and the steam is led to one compartment of the upper drum 7 through tubes 11, the steam flowing down through some of the tubes 9 into the drum 8 and thence up through other tubes 9 and reaching the outlet compartment from which the steam is taken through pipe 12.
In Fig. 2 I show a form similar to that of Fig. 1, except that the superheater is provided with another upper drum 13 which is connected to the drum S by a second bank of superheating tubes 14. In this case the drums of the superheater may be made without any transverse partitions, as the steam enterii'ig drum 7 through tubes 11 flows down to the drum 8 and thence through the second bank of superheating tubes up to the drum 13 whence it passes off through outlet 12". In this case similar parts are marked with similar numerals with the letter a applied.
The form of Fig. 3 is similar to that of Fig. 2 except that the superheater portion is inverted, the drum 8 becoming the upper drum and the drums 18 and 7 becoming the lower drums. In this case the tubes 11 lead the steam from the drum 2 down to the drum 7 whence it rises through the tubes 9 to the drum 8 and thence down through tubes 14* to the drum 13 where it is taken oif through outlet 12. In the second and third forms the gases are given two serial up and down passes among the superheating tubes after leaving the first pass of water tubes.
The advantages of my invention result from providing one pass for the gases before they reach the superheater tubes, the superheater forming the last pass or passes for the gases.
Many variations may be made in the form and arrangement of the drums, the tubes, the baffling, etc. without departing from. my invention.
I claim 1. A superheater boiler having upper and lower transverse drums connected by water tubes, a refractory baffle arranged to cause the gases to flow upwardly and lon itudinally of the water tubes, and a supefheater in the rear of the first water tube pass formed by the baffle and comprising substantially the entire heating surface of the boiler in the rear of said first pass; substantially as described.
2. A superheater boiler having upper and lower transverse drums connected by banks of tubes and refractory baflles arranged to give serial up and down passes to the gases, the water tubes in the first pass comprising substantially the entire water heating surface and the next two and final passes containing superheating tubes; substantially as described.
3. The combination with a boiler having at least one upper steam and water drum connected by at least one bank of tubes to a mud drum or drums, said water tubes forming substantially the entire first pass for the gases, a superheater in the rear of the boiler proper and within the setting, said superheater having an upper drum or drums connected by tubes to a lower transverse drum or drums, and refractory baflies arranged to give the gases one pass among the water tubes and the successive final pass or passes among the superheating tubes; substantially as described.
4. In a superheater boiler, a boiler proper having an upper steam and water drum connected by water tubes to a lower transverse mud drum the water tubes in the first pass comprising the entire water heating surface, a superheater in the rear of the boiler and within its setting, said superheater having baflies arranged to give the gases one pass through the water tubes and then two final passes among the banks of superheating tubes; substantially as described.
5. A superheater boiler having upper and lower drums connected by water tubes, said Water tubes forming substantially the entire heating surface in the first pass of the gases, a superheater in the rear of the boiler and within its setting and forming the entire heating surface back of the first pass, and a stack outlet in the rear of the superheater, a refractory baffle being provided between the superheater and boiler proper; substantially as described.
In testimony whereof, I have hereunto se my hand. 1
