FRANK H. F CHELSEA, MASSACHUSETTS APPARATUS FOB UTILIZING 'WASTE HEAT EROI PRODUCTS 0F CO-IBUSTION.

To all whom it mog concern.'

Be it known that I, FRANK a citizen of the United States, resi at Chelsea, in the county of Sufolk and tate of Massachusetts` have invented new and useful Improvements in A tus -for Utilizing Waste Heat from roducts of Combustion, of which the following is a specification.

This invention relates to improvements in apparatus for utilizing waste heat from products of combustion.

The object of this invention is to provide an apparatus adapted to be used in connection with boilers or heaters for the purpose of securing from the smokegas or products of combustion substantially all of the heat units which would normally be charged as waste through a stack to the air or otherwise, such heat units representing from 40% to 6592 of the total number contained in fuel.

Another object of this invention is to provide simple and eicient means for still further reducing the temgerature of smoke or gas and in carrying o the smoke and cinders.

Still another object of the invention is to provide meansfwtleereby the smoke llskaend air passages o apparatus may pt ree from smoke and cinders.

li'he invention in the an arrangement o parts set o in following tion and particularly Pd m te immens F- 1- erring to i e igure is a longitudinal sectional elevation of a boiler illustrating one form of apparatus embodymy invention.

charge orifice 8 into a smoke llue 9. In the present case however gases are preferably not discharged directly into the smoke iiue 9, but pass through an economizer or what is sometimes called a secondary boiler 10 of the usual and well known construction and adapted to heat water, which is aed thro said econcmizer, by means o lpipes Il an subsequently delivered to the boi er 5 in a partially heated state in order that the eiliciency of the boiler may not lbe reduced when the same is ini therein. A ffer leaving the secondary boiler 10 the snoke line 9 preferably descends slightly and is connected with a casing 12 preferably containing a plurality of smoke passages or ues 13 and a plurality of air passages or conductors 14 extending longitudinally of said casing and alternating with said smoke passages, said air passages being in close proximity to said smoke passages.

The casing 12 is preferably rectangular in shape and horizontally disposed, while a plurality of partitions 15 extend longitu nally of said easing dividing the same into passages which constitute said smoke and air paagcs. These partitions are refer abl corrugated transversely of their length, sai corrugations in the present instance gif vertically disposed as at 16. The de spacing of said partitions is by means of bolts 17 transversely of the casing through the side walls 18 and 19 thereof upon which are mounted sections 0f tubes 20, 20 offthe desn.'edf` h lengths whilci engage'opposite aces o e partitions I n the preferred embodiment of the invention there are four of said partitions 15 which divide the casing 12 into live passages 21, 22, 23, 24 and 25, the paages 21, 23and25beingairpassages,whilethepas sages 2 2 and 24 are smoke paages therebv providing a circulation of air along each side of the smoke paages.

The amount of smoke pasing therethrough is governed by dampers 22' and 24 adjacent the inlet ends of said lines.

The opposite ends of the ilu 22 and 24 unite with a common smoke liue 28 which is bent substantially at right angl to form @$1110 Clinge plpe ffor the blower- 32 preferably an elbow :29 extending downwardly carried thereby front'of the boiler; said erably operated'by 4an the er?) ,wat ma upwardly and connect with the erlydrectly extendsnansversely of to which said blower is to Pipe 34 hung 4-the "furnia I form thenxbq by the blower 32 the winnaar-Mee m24 for he mener:
