SPECIFICATION forming part of Letters Patent No. 542,371, dated July 9, 1895. Application filed July 28, 1894.. Serial No. 518,849 (N model.)
the production of certain inexpensive improvements for use chiefly with boilers in which the bridge-wall is located between the fire-box and the lines, as in marine boilers,
whereby more perfect combustion will be assured than is ordinarily obtained. In carrying into effect my improvements I have, of
necessity, utilized a principle wellknown and frequently adopted in this class of boilers namely, that of introducing directly into the combustion-chamber a supply of airindependent of that which passes th roughthe' grate and fire-pot, thus supplying needed oXygen to the gases, which otherwise would be non-inflammable and which would pass olf through the stack. By thus rendering it feasible to ignite said gases and produce perfect combustion all smoke, cinders, and other matter mingled with said gases may be consumed and the resulting caloric utilized to aid in making steam.
Heretofore more or less difficulty has been experienced in distributing thesupply of air throughout the combustion-chamber to oxygenate the gases in the type of boiler to which I apply my improvement, before portions of the latter escape into the stack, without interfering with the draft or obstructing the passage to the lines for the purpose of cleaning them, and it has also been difficult to estimate and provide the-exact volume of air required to produce the best results under all conditions.
boilers as well as new and for the heating of the inducted air before it reaches the combus- 5o tion-chamber.
In the annexed drawings, Figure l is an end View of a marine boiler embodying my invention; and Fig. 2 is a longitudinal sectional view of the same, taken on line ac x of Fig. 1.
Fig. 3 is an enlarged detached view of the distributing end of the induction-pipe. Fig. 4 is an enlarged view, partly in section, of the exposed end of said pipe, showing also a valve for regulating the inflow of air.
In the drawings, the letter A indicates as a whole a boiler of the horizontal-flue type. a
denotes the fire-pot ofone of its furnaces; b, the ash-pit; c, the combustion-chamber, located, as'here shown, immediately at the rear of the fire-wall b; d, the tubes of flues leading into asmoke-ehamber e, and e the smokestack.
In the bottom of the ash-pit is located a tube or pipev g, having its exposed end provided with a bell-mouth g.
bustion-cha'mber c, and its end is bent upward to a point about midway said chamber in Fig. 2. whence branch pipes h h 71. lead in directions calculated to discharge and distribute the supply of oxygen to the gases within said combustion-chamber most advantageously, each of said branch pipes being perforated, as shown. By locating the bridge-wall between the fire-box and the flues and at a short distance from the ends of the fines and placing the perforated end of the pipe g in the chamber thus formed between the bridgewall and the end of the lines, whereby the unconsumed particles are forced down over, the ends of the branch pipes, I am thus able to insure the perfect and instant intermingling of oxygen and gases, permitting said gases to ignite and burn all inflammable matter within the combustion-chamber, and by thus converting said gases and matter into caloric the best possible results are obtained from the fuel used.
The location of the induction-pipe g in the extreme lower part of the ash-pit should be Said pipe extends through the firewall b into the comnoted, as the high temperature of said ashpit serves to heat the pipe 9 and the current nace, and it is also desirable toshut oif the supply of air when not using steam or when it is desirable to bank the fires, and thismay be readily done by partially or completely closing the valve 70.
My invention costs very little, is easily applied to old or new boilers, and I find in prac- I tice that it results in a marked savingof fuel. 1
Having described my invention, I claim as new and wish to secure by Letters Patent In combination, a steam boiler provided with a fire box and an ash pit at one end a smoke chamber at the rear, tubes intermediate 3 the fire box and the smoke chamber, and a bridge wall between the tire box andthe flues and ata short distance from the lines, whereby a combustion chamber is formed between the bridge wall and the ends of the fines, and an air induction pipe leading from the front of the'boiler through the ash pit into the combustion chamber, the outer end of which is provided with a valve and the inner end is 'bent upward to a point substantially midway lOf the combustion chamber and provided with perforated branch pipes, substantially as set forth.
