Description
Patented Aug. 30, 1938 UNITED STATES PATE-NT porri-ce FURNACE Ireneus 'Basil Holtz, Ashviile, Pa. Applicationv February 10,1938, Serial No. 189,859 7 claims. (ci. 122-135) y This Vinvention relates toffurnaces of the hot water, steam or vapor type. f
In conventional furnaces of the round or lscniare type the hot fuel and the hot gases of combustion cannot transmit the heat units to the side walls very effectively so that the greater portion of the heat units must be dispensed through the upper regions of the furnace to the heating fluid which lis circulated in the boiler whereby too great a quantity of the heat units are lost in the flue and chimney.
It is an object of the present invention tok provide an elongated furnace which is substantially triangular in horizontal section with a relatively deep iirebox so that the heat units are not only transmitted to the heating fluid inheaders or coils which form a tortuous path for the hot gases of combustion but are also transmitted to the fluid along the extended side walls of the furnace whereby a maximum utilization of the BV. t. u.s s had.
Another object ofthe invention is the provision of a furnace which is substantially triangular in horizontal section and which has a hollow dome in communication with a header suspended below the dome to provide a tortuous path for the hot gases of combustion not only below the header but around the longitudinal side edges thereof and also above the header, the suspend- 3K0' ingmeansvfor the header being hollow` for placing the dome in communication with the header, while the suspendingmeans provides an elongated discharge channel for the hot gases of combustionand this channel is connected to the flue, v hollow members 'extending from the side walls of the lelongated furnace and having their inner ends spaced from each other to provide a restricted passage for the hot gases of combustion from the iirebox to an elongated flat passage below the header, said members being in communication with the dome and with coils forming the side walls of the furnace to not only provide for a continuous and complete circulation of the iiuid but to provide for a maximum heating surface in the furnace.
A still further object ofthe invention is the provision of a furnace which is substantially triangular in cross section in which a plurality of heating units are spaced from each other to provide a tortuous path for the hot gases of combustion from the flrebox so that the gases will travel at times from one end of the. furnace to the other before they are discharged in theusual flue, the top of the firebox including a pair of elongated members extending from the side walls of the furnace towards each other with their inner ends spaced from eachother to provide a restricted passage for the escape ofhot gases from the Firebox, said passage being progressively expanded frornthe front endV to the rear endof the furnace.
This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawing forming a part of the specification; nevertheless, it is to be understood that the invention is not conned to the disclosure, being susceptible of such changes and modifications as define no material departure from the salient features ofv the invention as expressed in the appended claims.
Y In the drawing:
Figure l is a vertical section taken along the line i-I of Fig. 2,
, Figure 2 is a horizontal section taken along the line2m'2 of Fig. 1, and V y,
'v Figure 3 is avertical longitudinal section `taken along the line l5 3 ofvFig. 1.
Referring more, particularly to the drawing, lil designates generally a shell or housing `of the furnace which is formed in sections, as shown atY Il in Figs. 2 and 3 and these sections are connectedtogether throughout the length of' the furnace in the usualmanner by the well known formof, conventional nipples although such nipple construction has not been illustrated.
, These sections rare hollow to provide chambers K l2 for a fluid which is heated for creating a circulation of either hot water, steam or vapor as the case may be. `The sections li are sho-wn as 'being vertically dispos-edalthough they may in- 35 clude horizontal sections of the conventional type.
A grate l5 is supported from the side Walls of the furnace and thereby divides the main body of the furnace into a rebox i6 and an ash pit l1. The rebox is relatively deep so that the hot coals I8 will not only be in contact with a large surface area of the side walls of the furnace but alarge heating surface will be presented to the hot gases of combustion.`
A vpair of hollow members 20 and 2lY project from the side walls of the furnace and form the top of the rebox. These members are hollow to provide chambers 22 which are in communication with the chambers I2 inthe side walls while the tops 23 of these members are'liiat. Theirr underfaces, as shown at 24, are curvedto form the top wall of the reboX. 'Ihe inner reduced ends 25 are spaced from each otherl to provide a central passage 26 which connects the rebox i6 55 with a at elongated passage 21 below a header 28. This passage 26, as shown in Fig. 2, is progressively .expanded from the front end to the rear end so that the wider portions of the passage are located in the reduced end 29 of the furnace and adjacent a ue 30.
A hollow dome 3| covers the top of the furnace and isjin communication at its side'eges with the vertical chambers |2 in the side walls o the furnace.
The header 28 is suspended from the'dome 3| by means of elongated hollow hangers 35 whereby the header 28 is placed in communication with.
the dome 3|` by means of the restricted passages 36. These hangers in connection with the upper surface 3'! of the header 28 and the bottom wall'V of the dome 3| form a channel 39 which is con-V nected with the fiue 30 at its rear end while it is in communication with elongated chambers 40 formed by the header 28, the hangers 35 and the These passages 40,
nace but which converge towards each other atV the rear end f the furnace.
While I have shown that the rebox in this instance is charged with coal it will be appreciated that either gas or oil may be utilized for fuel as is well known in the art.
It will be noted that the hangers 35 have their forward ends 50 spaced from `therfront Wall 48'of the furnace to provide restricted passages to permit the hot gasesfrom the passages 40 to enter the longitudinal discharge channel 39.
In view of the fact that the furnace is triangular in horizontal section the header 28 will likewise be approximately triangular as will be the members 20 and 2|. The grate 5 likewise Willrbe substantially triangular with the Wider portions of these members located at the front end of the furnace. l
In this type of construction large heating surfaces are presented to the hot gases of combustion and to the flame or fuel in the firebox while a tortuous path is provided for the hot gases throughout the furnace in order to delay the passage of the gases whereby they will come in contact` with the maximum heating surfaces for the uids in the various coils or header.
At .6 8 isy shownA a section nipple. A number of' thev nipplesY are employed for placing the various sections ofthe domein communication with each other.
