Application filed July 8, 1897. $eria1Noi643A79. (No model.)
ZbaZZ whom it may concern:
Be it known that 1, CHARLES E. BRINEY, of Allegheny, in the county of Allegheny and State of Pennsylvania; have invented a oer nace which shall be simple and inexpensive in construction, effective in" operation, and having its working members so constructed and related as to be protected from the destructive action of the heat of the furnace and capable of convenient and expeditious installation and removal without'disturbing the brickwork of the furnace.
The improvement claimed is hereinafter fully set forth.
Inthe accompanying drawings, Figure l is a vertical longitudinal section at the line to w of Fig. 2 through a steam boiler furnace, illustrating an application of my invention thereto; Fig. 2, a view in elevation of onehalf of the fire-front thereof; Fig. 3, a transverse section at the line row of Fig. 1; Fig. 4, a half-horizontal section at the line y y of Fig.1; Fig. 5, a'similar section at the line a z of Fig. 1; Fig. 6, a view, partly in elevation and partly in vertical central section and on an enlarged scale, of an air-injecting device embodying my invention; and Fig. 7, a plan or top view of the same.
My invention is herein exemplified in connection with the furnace of a return tubular steam-boiler Q, which is setbetween brick side walls R in the ordinary manner. The
furnace is closed at its front by a cast-iron fire-front 8, provided with fire-doors C and ash-pit openings D, and extends from the fire-front to a transverse bridge-wall B. The products of combustion from the fuel which is fired upon the grate-bars A pass through openings E above the bridge-wall into a con1- bustion chamber S below the boiler, and thence through a back connection (not shown) into the boiler-tubes T, from which they pass into the front connection or uptake P and thence to the exit flue or stack V. The furnace is provided with suitable means for preheating the air which is to be supplied above the grate-bars, these not constituting in and of themselves any part of my present invention and being in the instance illustrated a horizontal flue F, passing through the bridge wall and controlled by end doors or registers 0, said flue communicating bya vertical flue Gwith "another flue H, extending through the bridge-Wall and having end doors N. -The flue H communicates by vertical fiues I with horizontal flues J in the side walls R, and these in turn lead into a horizontal flue K, formed in the front wall a short distance above the fire-doors C.
It is obvious that any other suitable and preferred construction of air-heating passages, many of which have long been known in the artas, for example, fines or passages located in: the uptake P or in any other posiother suitable and preferred description, is
supplied to a furnace at any desired point above the grate-bars thereof through the draft or suction induced by a jet of steam or other fluid under pressure. Referring more particularly to Figs. 6 and '7, the preferred form of air-injecting device embodying my invention (any desired number of which devices may be applied to a furnace) is shown as comprising an air receiving and delivery chamber in the form of a T-shaped hollow casting having a cylindrical body 1, a lateral air-inlet passage 3, which communicates in this instance with the air-heating passage K, but which may be connected to any other appropriate avenue of air-supply, and an air outlet or discharge opening 2, leading into the furnace at one of its ends. The opposite end of the body, which abuts against the firefront 8, is internally threaded to engage an externally-threaded sleeve or nipple 10, by which the receiving and delivery chamber is connected to the fire-front 8, said sleeve passing freely through the fire-front and being engaged bya nut 9, by which it and the connected air receiving and delivery chamber are firmly secured to the fire-front with the capacity of ready detachment therefrom for removal when required. Fluid under pressure, which is preferably steam from the boiler, is admitted to the air receiving and delivery chamber by a fluid-pressure-supply pipe 4, leading from a point outside the furnace, said pipe fitting removably in the sleeve 10 and terminating, with a discharge-opening 5, formed in a plug at its inner end, adjacent to the bottom ofthe air-inlet passage 3. The discharge of steam or other fluid under pressure from the opening 5 is regulated and controlled by a supply-valve stem 6, having a valve formed on its inner end, which is adapted to seat on and wholly or partially close the adjacent end of the opening 5. The stem 6 passes through a union or coupling 7, which is connected to the outer end of the supply-pipe 4, a suitable packing-nut 12 being provided to prevent leakage, and carries a hand-wheel 13 on its outer end, by which it is operated. The stem 6 is preferably threaded to engage a nut in the union 7 in the ordinary manner, but may, if desired, be moved directly in and out by hand. Where a plurality of air-injecting devices is employed, as in the instance shown and as is ordinarily the case, steam is supplied to one of the unions 7 by a supply-pipe M, leading from the steam-dome or any other suitable point in the steam-space of the boiler, and to the other unions of the series by pipes 14, by which they are connected one to another.
It will be seen that the velocity and volume of the currents of steam discharged through the openings 5, and consequently the quantity of air injected into the furnace, may be readily and accurately regulated by proper adjustment of the supply-valve stems 0. The volume of air admitted to the furnace may also be controlled by the registers of the air-heating. flues or conduits. The air-injecting devices are set at such angle as will insure a thorough mixture of the currents of air and steam with the gaseous products of combustion, and to assist such mixture piers or buttresses of any desired shape maybe built up on the bridge-wall B. If desired, the main valve controlling the steam-supply pipe M or the individual supply-valve stems 0 of the air-injecting devices may be connected to an ordinary damper-regulator or to a thermostat for'the purpose of making the apparatus as a whole more or less automatic in its action. While my invention is herein shown as applied in a steam-boiler furnace, it is not limited in application to a furnace of such spean exit-opening for the products'of combustion.
A special feature of advantage of my improvement is found in the fact that the Working parts are effectively protected from the destructive action of the heat of the furnace and may be removed and replaced whenever required without disturbing the brickwork or any other portion of the furnace structure. The valve of the supply-stem 6, being of the needle class, can be readily regrouud when worn, and all the steam connections being outside the furnace they are accessible for renewal or repair whenever desired. The form of the air receiving and delivery chamber is such that it can be readily inserted in and removed from the brickwork of the setting without any material disturbance thereof.
