FUEL=ECONOMIZER.
SFEGIFIGATION forming part of Letters Patent No. 744,929, dated November 24, 1903. Application iiled February 25,1908. Serial 110.145,039. (No model.)
To tZZ whom t may concern.-
Be it known that I, JOHN MILNE, a citizen of the United States of America,and a resident of the borough of Brooklyn, city of New York, county of Kings, State of New York, have invented certain new and useful Improvements in Fuel-Economizers, of which the following is a specification.
My invention relates to new and useful improvements in fuel-economizers. One of its objects is to provide means for heating water preliminary to its being pumped into a boiler and to so construct the device that it may be placed in the fines of boilers, blast-furnaces, and the like or in connections thereto, so as to utilize the heat of the gases of combustion. In my Patent No. 519,023, dated May l, 1894, I have shown and claimed a similar device, and with the present invention a higher efficiency is secured, due to separating a portion of the tubes from the general body of the apparatus, so that the injection-water will take a separate and independent path before mixing with the main body of water, thus presenting a surface having a much lower temperature to the gases of combustion just previous to exit of the same.
Referring to the drawings, Figure l represents a partial sectional elevation of my invention in a chamber with its accompanying chimney. Fig. 2 shows a partial plan and section of Fig. l on the line a 0c.
The invention is shown to comprise an upper drum A, a lower drum B, the said drums being connected by tubes C, between which latter are shown baffle-plates O O. From the lower drum B there extend other tubes D, which are secured at their upper ends into a header E, the said tubes being staggered with each other. The header is supported by the upper drum A by means of brackets F, ex-
tending from the said header; but the ,interior of the header is not in communication with and is isolated from the upper drum. A feed-pipe G is connected to the header E, and an outlet-pipe H extends from the upper drum A, and the drums have openings for the manholes A B, respectively.
The apparatus is supported on saddles I, that are carried on beams J, resting on columns K, and although the plan view shows the said structure of saddle, beam, and columns on one end of the upper drum only it is evident that the same construction is intended for the other end of the said drum.
In the drawings a flue is shown at L, a chamber at M, and a chimney at N. In the flue L or at any convenient situation there may be placed grates P, that can be fed with fuel through an opening Q, thereby constituting a furnace, so that the heat imparted by the gases to the water in the tubes O may be intensied. By using the grates the gases coming from the iiue L may be cut off and the apparatus employed as a steam-generator.
When using my invention, the heated gases resulting from combustion pass from the flue L through the chamber M on their way to the chimney N, and in so doing pass first around and about the tubes C and then about and around the tubes D. The water to be heated enters through the pipe Gr', passes through the tubes D, and then into the lower drum B, after which it rises in the tubes O to enter the drum A, being finally delivered by the outlet-pipe H.
My invention may be modified by placing lthe tubes D with the header E at either or both ends of the upper drum A, and the apparatus may also be turned ninety degrees from the position shown in the drawings with reference to its location in the chamber.
I-Iaving described my invention, I'claimil.' In a fuel-economizer, the combination of an upper and a lower drum, tubes connecting the said drums, other tubes extending from the lower drum and capped by a header having its interior isolated from the upper drum.
2. In a fuel-economizer, the combination of an upper and a lower drum, tubes connecting vthe said drums, other tubes extending from the lower drum, a header having its interior isolated from the upper drum capping the second lot of tubes, a feed-pipe connected with said header, and an outlet-pipe connected with the upper drum.
3. In a fuel-economizer, the combination of an upper and a lower drum, tubes connecting the said drums, baffle-plates between some of the said tubes, other tubes extending from the lower drum, a header 4having its interior IOO isolated from the upper drum capping the second lotv of tubes, a feed-pipe connected with said header, and an outlet-pipe connected with the upper drum.
4. In a fuel-economizer, the combination of an upper and a lower drum, manholes in the drums, tubes connecting the said drums, baffle-plates between some of the said tubes, other tubes extending from the lower drum, a header having its interior isolated from the upper drum capping the second lot of tubes, a feed-pipe connectedwithsaid header, and an outlet-pipe connected with the upperdrum.
5. The combination of a nue, a chimney, a chamber connecting the said elements, an upper drum, a lower drum, tubes connecting the said drums, other tubes extending from the lower drum, a header having its interior isolated from the upper drum capping the second lot of tubes, a pipe connected with the header, andY a pipe connected with the upper drum.
6. The combination of a iiue, a chimney, a chamber connecting the said elements, an upper drum, alower drum, tubes connecting the said drums, other tubes extending from the lower drum, a header having its interior isolated from the upper drum capping the second lot of tubes, a pipe connected with the header,a pipe connected with the upperdrum, and means to suspend the upper drum.
7. The combination of a liuc, a chimney, a
chamber connecting the said elements, an upper drum, a lower drum, tubes connecting the said drums, other tubes extending from the lower drum, a header capping the second lot of tubes, a feed pipe connected with the header, and an outlet-pipe connected with the upper drum, saddles under the upper drum, girders supporting the said saddles.
8. The combination of a flue, a chimney, a chamber connecting the said elements, an upper drum, a lower drum, manholes' in the drums, tubes connecting the drums, other tubes extending from the lower drum,a header capping the second lot of tubes, the said tubes lbeing staggered in the header, a feed-pipe entering the header, an outlet-pipe extending from the upper drum, and a furnace for fuel adjacent to the tubes.
9. The combination of a chimney, a chamber connecting therewith, an upper drum in the chamber, a lower drum, tubes connecting the drums, other tubes extending from the lower drum, a header having its interior isolated from the upper drum capping the second lot of tubes, a pipe connected with the header, and a pipe connected with the upper drum, a grate adjacent to the tubes, and an opening to supply fuel to the grate.
10. In a steam generator and economizer the combination of an upper drum, a lower drum, tubes connecting the drums, other tubes extending from the lower drum, a header having its interior isolated from the upper drum capping the second lot of tubes, a pipe connected with the header, a pipe connected wit-h the upper drum, and a furnace arranged with the said elements.
