This invention relates to a furnace that is especially useful in connection with the USB.
The invention will be understood from the description in connection with the accompanying drawings,.in which Fig.J 1 is a vertical section through a furnace, partly 'Y broken away, showing an illustrative em` single bodiment of the invention; and Fig. 2 'is a section along the line 2 2 of Fig. 1. In the drawings reference character indicates the walls of a furnace that may be lined in the usual way with, material 6, that is highly refractory.` The combustion space of the furnace is indicated at 7 below whichthe ash hoppers 8 are located. The ash hoppers are provided with sloping floors 9 along which the slag and ashes may be withdrawnthrough doors 10 in the side ofthe furnace. u
' Water tubes 12 extend across the furnace between the combustion space and the ash hoppers, through the walls of the furnace and enter headers' 13 and 14 on the outside of the furnace walls. The headers 13 and 14 may be connected to the circulation System of the boiler -(not shown) or to any other convenient source of water through connections 15.A A valved drain pipe 16 may be provided for the inlet header 13. The tubes l2 are preferably slightly inclined upwardly from theinlet header toward the outlet headeigand are so disposed across the furnace that groups of tubes are ,located in sloping planes, as most clearly shown in Fig. 2, thus formin roof-shaped arrangements. Each row o tubes in a laneS has` the spaces between the tubes c osed` by plates or -langes 18, and spaces lare leftbetween certain ofthe other tubes through which the slag and ashes descend into the ash hoppers. In the illustrative embodiment of the invention, certain of the tubes are located in a lowermost plane, and other tubes are located in higher planes without having two tubes in the same vertical plane. The tubes maybe bent near portions thereof that pass thrcugh the furnace walls, as best shown in Fig. 1, in an 'commodate screw hand-wheels 21 by 200,797, and in Germany Iarchf12, 1926.
appropriate manner to procure the arrangement just described.
In the normal operation of the furnace, the spaces between the lowermost tubes 12 are left open 'for the passa e of slag'and ash into the ash hoppers. f the doors 10 are opened while the spaces are leftopen between the tubes, the inrush of cold air will interfere with combustion ,in the furnace. In order to prevent this interference, slldable dampers 19 are provided to close the spaces'between the lowermost tubes 12 when thedoors-lO are to be opened. Rods 20 are connected to the dampers 19 and extend through a wall of the furnace, and
have their extending ends threaded to acwhich the dampers can be slid back and forth transversely of the tubes to open or close the spaces between them. The edges of the dampers 19 rest upon supports 22 that may be provided with flanges 23 to serve as guides for the dampers.
I claim: l
1. In a furnace, water screen tubes extending acrossthe lower portipn of .said furnace arranged in separate planes each inclined to the horizontal with spaces between some of said tubes and dampers for controlling said spaces.
2. vIn tending across the lower portion of said fur-l nace arranged in separate planes each inclined to the horizontal, withA spaces between some of said tubes and dampers operable from the outside of said furnace for controlling said spaces.
3. In a furnace, water 'screenl tubes extending across the lower portion of said` aV furnace,water screen tubes ex-v furnace arranged in separate ,planes each f inclined to the horizontal, with spaces between some of said tubes and dampers slid-n able transversely `of said tubes for control ling said spaces. f
4. In\a furnace, a combustion space and an ash hopper, tubes'arranged in separate planes each inclined to the )horizontal lccated between said combustion space and ash hopper and means to close permanently the spaces between some o f said tubes andmeans to close the tubes at will.
spaces between some of the \other i 5. In a furnace, a' combustion space and an ash hopper, tubes arranged in separate planes each inclined to the horizontal located between said combustion space and ash hopper, means to close permanently the spaces between some of said tubes and means to close the spaces between some of the other tubes at will, said last named means comprising dampers movable across said tubes. A
6. In a furnace, a plurality of spaced groups of water tubes extending across the lower portion of said furnace the tubes of each group lying at a plurality of elevations oiset from each other, the spaces between the lowermost tubes and those at higher elevations of each group being closed and the spaces between the lowermost tubes in adjacent groups being closed by dampers.
7. In a furnace, a plurality of spaced oups of water tubes extending across the ower portion of said furnace the tubes of each group lyin at a plurality of elevations and in di erent vertical planes, the spaces between the lowermost tubes and those at higher elevations of each group being closed and the spaces between pairs of tubes in the lowermost row of tubes being closed by dampers.
