commission CHAMBER.
Application filed May 12, 1925. Serial No. 29,654. Y
The present invention relates to combus tion chambers, and more particularly to radiating combustion chambers double pass type disclosed in the patent to Clarence E. Hawke and Boyd M. Johnson,
No. 1,542,552, granted June 16, 1925.
This type of combustion chamber, as shown in said co-pending application, is usually constructed with an internal hori- Zontal partition which separates the two passes except at the rear end of the chamher where they communicate with each other. In using this type of combustion chamber it has been found that in certain cases where the combustion rate was very' high, as when burning oil, there was a. tendency tooverheat this partition member which had no chance to radiate its heat, the result being that it gave way of its own weight and rendered the furnace inoperative. When burning powdered coal in this type of combustion chamber, there is also,
react with the silicon carbide or other refractory material out of which the walls of the combustion chamber are constructed.
l Vith this construction the walls of the com-. bustion chamber are also more umformly heated than in the type of combustion chamher having the internal partition and a larger amount of radiating surface is provided.
In the accompanying drawings:
Figure l is a transverse sectional view through a furnace adapted for the heat treatment of ceramic ware and similar articles and having a preferred form of combustion chamber constructed in accordance with my invention installed therein;
Figure 2 is a section on the line IIII of Figure 1;
Figure 3 is a transverse sectional view of the combustion chamber shown in Figure 1 on a slightly larger scale;
of the b Figure 4t is a side elevation partlybroken away of a portion of the combustion chainmy invention;
Figure 6 is a perspectiveview of onev of the hollow tiles used for spacing the top of the bottom pass from the bottom of the top pails in the construction shown in Figure an Figure 7 is a perspective View, of another modification of my invention.
Referringv to the construction shown in Figures 1 to 4: inclusive, 2 designates a heat per pass 5 has a burner opening 8 in the front end thereof into which projects an oil burner 9 suppliedfwith oil through a pipe 10. Secondary air is supplied to the burner' opening 8 through a pipe 11. The forward end of the lower pass 6 of each combustion chambercommunicates with a flue 12 be neath the floor of the heating chamber 3.
By reference to F iguresf3 and 4 it will be seen that the four inclined walls 13, 14:, '15
and 16 of the X-shaped partition are reino forced at intervals throughout the length of Y the partition by vertical webs 17. The outer surfaces of the X-shaped partition are exposed to the outside air so that the walls of the X-shaped partition are adapted to radiate heat as freely as the remaining portions l of the walls of the upper and lower passes and consequently the walls of the X-shaped partition will not be exposed to substan tially greater temperature conditions than 1 the remaining portions of the walls of the passes. It will be appreciated also that this construction greatly increases the total amount of radiating surface of the combustion chamber as compared with the type of construction in which the usual internal horizontal partition is employed.
In the modified construction shown in Figure 5 the upper and lower passes 18 and r 19 of the combustion chamber are separated Figure 5 is a perspective view of a moditied form of combustlonchamber embodying 60 combustion chamber v is 75 by a ventilated"*horizontal partition 20 formed of hollow tiles 21. These hollow tiles form the top wall of the lower pass and bottom Wall of the upperpass. Thisventilated partition permits the free circulation of air through the same and is adapted ingwith each other at one end of the structo radiate heat freely.
In the modified construction shown in Figure 7 the upper pass 22 ofthe'comb'us tion chamber has its bottom wall separated from the "top wallof the lowerpass23 of the chamber by ordinary bricks 24 or other suitable shapes spaced apart to permit circulation'of air between said lower and upper Walls and to'permit' said walls to'radiate heat freely. It will be seen that'in this construction the two passes of: thecombu'stion chamber'ma'y be built'up of individual sections 25.
