1 To all to 7mm it may concern Be it known that I, 'Josnrrr N. TOMES,
a citizen of the United States, residing at and more particularly to a smoke consumer for use in connection with furn aces by means of which the smoke and other products of combustion are conducted through the furnace grate so as to be burned thus eiiecting a material saving in fuel.
One of the main objects of the invention is to provide a smoke consumer of simple and inexpensive construction which may be readily applied to furnaces of standardconstruction.
A. further object is to provide a smoke consumer which may be operated, after once started, by steam generated within the boiler of the furnace. 5
Further objects will appear tailed description.
In the drawings:
Figure 1 is a front view of a furnace of standard construction with a smoke consumer constructed in accordance with my in vention applied.
FigureQ is a back view.
Figure 3 is a central vertical longitudinal section through the furnace showing the smoke consumer applied, parts being shown in section in this view.
As illustrated, the smoke consumer is applied to a furnace of standard construction including -a casing A within; which is sup ported the boiler 13 and grate C beneath the boiler, the inner end of this grate be ing supported by the usual fire wall D. The boiler is of tubular construction being provided with the longitudinally extending spaced flue tubes E of known type, these tubes communicating at their forward ends from the dewith a smoke box F which communicates at.
its top with a stack G provided with a suit able valveor damper 1. combustion from the fire box flow rearwardly over the firewall D through the space H inwardly extending tubes 8 coinuiuniia'te The products of.
and upwardly into the rearward ends of the hue tubes, I H A smoke return pipe 2 communicatesat its upper endwith the smoke box F below the damper I, this pipe communicatingat'its 'lower'end with the ash. pit adjacent the forward end thereof, beneath the grateC, as in r 5'42. Lxll t 7 i I t} i ine u. .a ian o o .sui a.) o type is moui.
this fan'being provided with a pulley secured thereon by means of which the fa.
may be readily connected to a motor for oper ing the-same. "This fanis providedwith an nt'ake p pe 5 and. a discharge pipe 6, the discharge pipe commim cating. at its up per "end with a header box or "casing i 7 mounted at the central portion of the back of the furnace casing A. A plurality-.of
with the headercasing 7 at their outer ends, these tubes projecting into the upper portion of space H and being disposed in alinement with and adjacent to flue tubes E of the boil or. A steam supply pipe 9 communicates with the casing 7 at the top thereof, this pipe being connected. to the steam dome B of the boiler-B and provided with a suitable control valve 10. The flow of air from fan 3 into casing 7 is controlled by a damper 11 in the fan outlet pipe 6. i i
In practice, when first starting the fur-- nace, the valve 10 is closed, valve 11 being ed at the rear of the jlurnace,;the shaft of.
openyand the fan i is operated through the medium ofan electric motor or in any other suitable vmanner so as to force air into the header casing 7 through pipe 6. The damper l of stack G is so adjusted as to cause the products of combustion flowing into the smoke box F to flow into the,
discharged through the tubes 8 at high velocity this air flowing throughthe flue tubes of the boiler and serving to create a partial vacuum within the upper portion of space H thus inducing a current of air and the products of combustion which have been returned to the ash pit by the return ipe 2 to flow upwardly through the.
grate I and the fire supported thereby. This mixture of air and smoke which is generated upon first starting the furnace is thus caused to flow through the fire supported by,the grate so as to be consumed thereby. It is apparent that the tubes 8;
become heated to a great degree,' during operation of the apparatus; As the smoke generated'during operation of the furnace is composed to a great extent of gases the same may be burned, thus etiecting a ma terial saving in fuel While also preventing the escape of smoke into the atmosphere. After the apparatus has been in operation for a short time so that steain is generated within the boiler VB at the desired pressure, the tan 3 may be stopped, after which the damper or valve 11 of pipe 6 is closed, valve 10 of the steam pipe being open so as to admit steamunder pressure into the header casing 7. This steam is injected by. the heated injector'tube, at high velocity and in a'small, fine spray into the flue tubes Eand acts in the same manner as the air in the operation previously described to induce flow of the products of combustion through the return pipe 2 and grate C. This steam mixing with v the products of ,combustion and then passing through the fire supported by the grate C is, under the influence of the high temperature of the fire. a
p I: have found by experience that the Witnesses damper linay be readily adjusted soas to insure complete combustion or burning of the combustible ingredients of the products of combustion from the furnace, thus effectually preventing escape of smoke into "the atmosphere While also utilizing these combustible boiler B. V
What I claim is: 7
products for heatin the i V i a In combination with a'furnace including a boiler, a smoke box in communicationwith the'firebox and the ashpit, means operable to close the smoke box whereby the smoke will be discharged into said ashpit, a header, tubes extending from the header and terminating short of and relatively JOSEPH Ni TOMES.
