5 character whereby the water may have rapid and unrestricted circulation to permit quick generation of steam in maximum amounts with a minimum consumption of fuel.
Another object of this invention is the o provision of upper and lower pairs of drums connected by pairs of banks of tubes so constructed as to permit free circulation of the water and preventing formation of steam pockets one pair of banks of tubes being arranged in direct contact with the combustion gases from the fire boX and inter-crossing while the other pairs of banks of tubes diverge downwardly within passages for the gases after acting on the inter-crossing banks of tubes to assure maximum use of the heat.
A further object of this invention is the employment of a pair of steam drums instead of a single drum to reduce turbulence of the water in said drums and the latter having multiple steam take off tubes the entire length thereof reducing the tendency to lift water from the drums.
With these and other objects in view7 this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which y Figure 1 is a transverse sectional View illustrating a steam boiler constructed in accordance with my invention.
Figure 2 is a side eleva-tion partly in section illustrating the same.
Referring in detail to the drawings7 the numeral 1 indicates a casing or housing in which is constructed a fire box 2 receiving heat from a series of burners 3 adapted for burning gaseous or liquid fuel. Parallel steam drums 4' and 5 are arranged in the upper portion of the casing l directly above the fire box. Lower drums 6 and 7 are arranged in the casing 1 adjacent the fire bon7 1932 Serial No. 625,989.
and are connected to the drums e' and 5 respectively by banks of downwardly diverging tubes S and 9. The drums 6 an 7 are connected to the drums 5 and el respectively by banks of tubes l0 and 1l. rllhe tubes 10 and 11 inter-cross each other as shown in Figure 1 directly above the fire box rendering a formation of substantially X-shape so that the products of combustion and heat from the tire box may play directly against the banks of tubes 10 and 11. Partitions or deflcctors 12 are arranged between the banks of tubes 8 and 10 and 9 and 11 and cooperate with the partitions 12 in forming chambers or passages 13 in which the banks or tubes 8 and 9 are located. The combustion gases after passing upwardly are directed downwardly through the passages 13 and into upwardly converging passages le communicativc with lues l5 that lead to the usual smoke stack; rhe upwardly converging passages lel are formed by the partitions 12 and the walls of the casing. lt is to be understood that the walls of the casing arc suitably lined with heat resisting material.
A deiiector 16 is arranged between the drums il and 5 above the inter-crossing of the tubes 10 and ll for aiding in deflecting the heat and products of combustion downwardly through the passages 18. y The drums are connected by a wall 1T forming a closure for the upper part of the heat chamber of the furnace and arranging the major portions of the drums 4 and 5 within the heat. chamber. The path of travel of the heat and fumes from the fire box is as indicated by the arrows in Figure 1.
A steam collecting drum 18 is located between the drums 4 and 5 and is connected to u the latter by a. series of steam tubes 19 whereby the steam generated within the drums 4 and 5 may readily pass into the collecting drum 18 and thence into a super-heated steam outlet header Q0 connected to the steam collecting drum 1S by a series of removable tubes 2l extending downwardly through the bank of tubes l1 and 12 to form superheaters which comes in direct conta-ct with the heat and products of combustion as they rise from the fire box. The steam collecting drum 18 is provided with a suitable safety valve Q2.
Feed water heaters 23 are arranged within the passages 14 and are fed with water through inlet pipes 24 which communicate therewith at the upper portions thereof. Outlet pipes 25 are in communication with the lower portions of the feed water heaters 23 and are in turn connected to the drums l and 5. The pipes 25- are provided with control valves Q6, thus it will be seen that the water is pre-heated and then fed into the. drums 4 and 5 whence it circulates downwardly through the banks of tubes 8. and 9 into the drums 6 and 7. `The heated water rises from the drums 6` and 7- through the banks of'tubes l() and 11 tothe drums 5 and' 4, becoming` highly heated to generate steam in said drums which passes into, the steam collecting drum 18, thence into the super-heated steam outlet header or drum Q0.
The feed water heaters each are constructed of a series of compartments as shown in Figure 1 in which are arranged series of communicative tubes so that the water circulating downwardly prior to entering the steam drums, may be effectively pre-heated.
The boiler may be heated by fuel: other than liquid or gaseous fuel if desired.
While I have shown and described the preferred embodimentlof my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of my invention, as claimed.
Having thus described my invention, what I claim is A steam boiler comprising a casing, a fire box in said casing, means for heating the fire box, a pair of parallel steam drums arranged in the casing directly above the lire box, lower drums arranged in the casing adjacent the lire box, downwardly and out wardly extending banks of tubes connecting the steam drums tothe lower drums, diago nally extending and inter-crossing banks of tubes connecting the lower drums to the steam drums and arranged directly in the path of combustion from the tirey box, dclectors arranged between the first and second banlrs of tubes, Vdeflectors arranged be- `f"" tween the first mentioned deiiectors and the walls of the casing for forming downwardly and upwardly extending passages with the first mentioned banks of tubes arranged in the` downwardly extending passages, means HENRY A. ULRICH.
