FEED-WATER HEATER.
SPECIFICATION forming part of Letters Patent No. 590,830, dated September 28, 1897.
Application filed February 20,1897. Serial No. 624,365. (No model.)
To ctZl whom it n'tct'l/ concern.-
Be it known that I, LOUIS MARIE GABRIEL DELAUNAY-BELLEVILLE, a citizen of France, residing at Paris, France, have invented certain new and useful Improvements in or Connected with Steam-Generators and Feed- XVater Heaters Therefor, of which the following is a specification.
My invention consists in the combination, with steam-generators, of a novel feed-water heater or economizer which is in two parts or sets, one of which is placed above the steam-generating chambers or tubes, while he other is arranged at the side in the rear or above the boilers in a descending or ascending smoke flue, conduit, or channel, there being interposed between the two parts or sets of the economizer a second or supplementary gas-combustion chamber. H
In order that my invention may be clearly understood, I represent in the accompanying drawings constructions according to my invention from which its nature and the manner in which it can be performed ,to meet varying requirements will be readily understood. Figures 1 to 4 represent a group of boilers provided with an economizer constructed in accordance with my invention, Fig. 1 being an elevation of the group, the left half of the figure being in elevation andthe right-hand part in longitudinal section, the section'being taken on the line A B, Fig. 3. Fig. 2 is a plan partly in horizontal section onthe line tubes not being shown in this figure.
C D, Fig. 1, and partly in horizontal'section on the line E F, Fig. 1, the steam-producing Figs. 3 and 4 are transverse sections upon the lines G H and I J, Fig. 1, respectively. Figs. 5 to 8 illustrate a modified construction, Figs. 5 and 6 being, respectively, a longitudinal section on the line K L, Fig. 7, and a longitudinal elevation, and Figs. 7 and 8 being transverse sections on the lines M N and O P, Fig. 5, respectively. Figs. 9 to 11 represent a further modification, Fig. 9 being partly a longitudinal elevation and partly a longitudinal section on the line Q E, Fig. 11. Fig. 10 is a horizontal section on the line S T, Fig. 9; and Fig. 11 is a transverse section on the line U V, Fig. 9.
In all the figures the barbed arrows indicate the course of the combustion-gases and the barbless or plain arrows indicate the direction in which the feed-water circulates.
1 1 2 2 are the steam-generating chambers of the boilers.
3 3 4 4 are the chambers of the economizers placed above the boilers, there being one economizer for each boiler.
5 5 6'6 designate the additional combustionchambers interposed between the steam-producing chambers 1 2 and the economizerchambers 3 4.
7 8 are'the economizer-chambers placed beside and between or above the boilers. They are within compartments situated beside, be: low, or above the smoke-flue leading to the chimney. The chamber 7 serves as one common economizer for all the boilers at the same side with itself, while the chamber 8 is an economizer common to the boilers on the other side.
9 10 are smoke-fines forming an additional combustion-chamber between the economizer 3 and 7 and 4 and 8, respectively.
11 and 12 are smoke-fines next in order to the economizers 7 and S, the cleaning of which smoke-fines is effected by means of the doors 13 and 14.
15 15 are smoke-fines leading to the chimney, and 16 17 are the boiler-furnaces, having charging-doors 18 1S and ash-pit doors 19 19.
The feed-water enters each boiler-front through a pipe 20, which conducts it into the lower collector 21 of one of the common economizers, say 7. The water runs through the chambers of such economizer and passes on to its upper collector 22, whence it issues through the pipe 23, which passes to the right and left. From the pipe 23 the pipes 24 24 branch off and these conduct the water to the feed-water regulators 25 25 of theboilers. In the case of each boiler the pipe 26 conveys the feed-water from the self-controlling feedregulator 25 to the corresponding economizer 3, the water traversing the pipes of such economizer vertically either in the upward or in the downward direct-ion or horizontally,
or both vertically and horizontally, in alter-.
nate succession, and issues through the pipe 27, which conducts it to the feeding-injector 28, placed upon the purifying-collector 29,
through which injector the water enters the boiler proper.
If the vertical space available be insufficient to admit more than one of the economizcrs 8 and 4: to be situated on either side, one only is used-namely, the one that is nearest to the smoke-fluethe gases from the terminal boilers being brought down below the economizer which is retained, say 3. This economizer 3, moreover, will in that case receive through the pipe direct the water which is leaving the economizer 7, and the pipes 2% 2i will then conduct the water from the economizer 3 to the feed-water regulators of the boilers placed 011 the same side as this economizer, the pipes 26 26 will be dispensed with, while the pipes 27 27 will lead from the feed-regulators to the injectors direct.
My invention affords the following advantages:
First. In the event of scarcity of available space in the direction of height, provided there is sufficient space in the horizontal plane, the number of tubes in the economizer of each boiler may be reduced, while the economizers may be made to retain a suflicient heating-surface by connecting them with the economizer placed beside or in the rear of the boilers or within the vertical smoke-flue forming the base of the chimney.
Second. IVhere ample space is available both vertically and horizontally, so that the necessity of reducing the number of tubes of the economizer of each boiler isavoided, the heating-surface will in consequence be materially enlarged.
Third. IVhere combustion is conducted on a large scale-say at the rate of from one hundred and fifty to two hundred kilograms per hour and per square meter of grate and where the fuel used is soft coal and the gases may not be entirely consumed when they have passed into the economizers placed above the boilers and where want of space in height has narrowed down the reheatingsurface of these last-mentioned economizers the second or additional combustion-chamber will prove very serviceable in completing the combustion.
Fourth. Owing to the furnaces being charged periodically fluctuations occur in the activity of the combustion, and more particularly in the volume of the gases arising from the furnace, whence there result changes in the temperature of those gases which have passed beyond the econ om izers situated above the boilers. The economizer situated within the smoke-flue being common to several boilers enables any surplus heat which the gases may still retain on lcavin g the first feed-water economizers to be utilized.
Fifth. The feed-water undergoes its preliminary heating by contact with those gases which are least heated, and in its progress through the first economizer, as well as during its passage hence into the succeeding economizer, it gradually meets with more and more highly heated gases, which arrangement is calculated great-1y to assist the process of absorption of the heat of the gases by the Water.
Sixth. Altogether by .reason of the wide heating surface wherewith the economizer situated within the smoke-flue at the foot of the chimney may be provided, whether or not it be common to a number of boilers, that economizer first receives feed-water at the lowest temperature and absorbs the heat from the gases in a more complete manner than the economizer placed above the boiler could do alone.
Having now particularly described and ascertained the nature of thisinvention and in what manner the same is to be performed, I declare that what I claim is r The combination with a plurality of boilers and boiler-furnaces, and a smoke-flue common to all of them, of two sets of feed-water heaters or economizers, one set being arranged over the boilers and the other set in the smoke-flue, and an auxiliary or supplemental gas-combustion chamber interposed between the two sets of feed-water heaters or economizers, substantially as described.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
