2 Claims.
The invention relates to boilers and more especially to hot water boilers.
The primary object of the invention is the provision of a boiler of this character, wherein a maximum area or surface is arranged for direct contact with the body of burning fuel, thereby increasing the heating qualities of such boiler without necessitating excessive consumption of fuel for such purpose.
Another object of the invention is the provision of a boiler of this character, wherein the fluid to be heated is circulated within spaces, the walls of which are in confronting relation to the fuel bodywhen burning so that a maximum of heat can be transmitted to the fluid, whereby the temperature thereof may beraised quickly and economically maintained at a high degree, the boiler in its entirety being of novel construction.
A further object of the invention is the provision of a boiler of this character wherein the construction thereof is such that the products of combustion from the fuel must travel along the entire surface of the heating units before the spent products of combustion are exhausted or escape from the boiler, thereby insuring maximum heating qualities and perfect efficiency in the working of the boiler.
A still further object of the invention is the provision of a boiler of this character which is comparatively simple in construction, thoroughly reliable and eflicient in its purpose, strong, durable, and inexpensive to manufacture and install.
With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention, and pointed out in the claims hereunto appended.
In the accompanying drawings:
Figure 1 is a front elevation partly in section of a boiler constructed in accordance with the invention.
Figure 2 is a top plan view thereof.
Figure 3 is a sectional view on the line 3-3 of Figure 1 looking in the direction of the arrows.
Figure 4 is a sectional view on the line 4--4 of Figure 1 looking in the direction of the arrows.
Figure 5 is a sectional view on the line 5-5 of Figure 1 looking in the direction of the arrows.
Figure 6 is a sectional view on the line 6--6 of Figure 1 looking in the direction of the arrows.
Figure '7 is a sectional view on the line 7-7 of Figure 1 looking in the direction of the arrows.
' Figure 8 is a sectional view on the line 88 of Figure 4 looking in the direction of the arrows.
Similar reference characters indicate corresponding parts throughout the several views in the drawings.
Referring to the drawings in detail, the boiler constituting the present invention has a base body 10 which is preferably upwardly tapered and forms an ash pit 11 accessible on the opening of a front door 12. This body 10 at its upper end. carries a grate 13 which may be of any approved type.
Superimposed upon the body 10 is the cylindrical outer shell 14, the same including the units 15, 16 and 17 respectively, these being united in any suitable manner and this shell constitutes the casing of the boiler. The unit has formed therewith an inner corrugated wall 18, the same being spaced from the outer wall of said shell 14 and forms a fluid space 19. The unit 16 also is formed with a corrugated inner wall 20 spaced from the outer wall and constitutes therebetween a fluid space 21, while the unit 17 has the inner wall 22, this for a part thereof constituting the bottom to a hollow crown 23 of said unit providing a fluid space 24. The spaces 19, 21 and 24 are intercommunicative through connections 25, these being vertically arranged at equidistant spaces from each other concentrically of the said units. The units 15, 16 and 17 below the crown 23 constitute a fire pct 26 and a combustion chamber 27, the fire pot 26 being accessible on the opening of the front fire door 28. The shell 14 of the boiler also carries the clinker and cleanout doors 29 and 30 respectively, at the front of the furnace. Rising vertically and disposed centrally with respect tothe crown 23 is a steam outlet pipe 31 and this crown, through flues 32 formed therein, discharges the spent products of combustion through a dome 33 to an outlet flue 34 leading from said dome. The dome concentrically of the pipe 31 is equipped with a removable two-part cap 35 latched by the fasteners 36 carried thereby.
Connected with the unit 16 are the main feed pipes 37, while connected with the unit 15 are the return pipes 38 of the water system associated with the boiler.
Depending from the bottom of the crown 23 centrally thereof into and combustion chamber 26 is a mushroom-shaped water leg or column 39, while formed concentrically of this leg or column are hollow nipples 40 so as to increase the heat surface the boiler. The column or leg at the lowermost portion thereof communicates with a water circulating pipe 41 which opens into the space 19 of the unit 15.
Formed with the inner wall 20 of the unit 16 is a hollow annular ledge 42 having depending hollow nipples 43, these increasing the heat surface of said unit 16. The inner wall 18 of the unit 15 has projecting from its corrugations, near the upper end of said unit, inwardly extended radially disposed hollow nipples 44.
It should be seen that by the arrangement and in the construction of the units at the inner walls thereof a maximum heating surface is presented and thus a high efiiciency is had in the use of the boiler with a minimum consumption of firing fuel. It is of course to be understood that the boiler is susceptible for use in heating with steam, vapor or water.
The corrugations of the inner wall of the unit 18 are vertically disposed, while the nipples of the units 16 and 17 depend within the combustion chamber.
What is claimed is:
1. A boiler of the character described comprising an ash pit base, an outer shell supported thereby and including superposed units having inner walls spaced from the outer shell to provide fluid spaces therein, connections establishing communication between the spaces of the units, hollow nipples projected from the inner walls of said units, a crown formed on the uppermost unit, a hollow fluid leg depending from said crown and having communication at its lowermost end with the fluid space of said lowermost unit, a dome rising from the crown and having an outlet flue for discharging spent products of combustion, flues formed in the crown for establishing communication between the interior of the boiler and the said dome, a fluid outlet pipe leading from the crown, and a cap about said fluid outlet pipe and detachably connected with the dome.
2. A boiler of the character described comprising an ash 'pit base, an outer shell supported thereby and including superposed units having inner walls spaced from the outer shell to provide fluid spaces therein, connections establishing communication between the spaces of the units, hollow nipples projected from the inner walls of said units, a crown formed on the uppermost unit, a hollow fluid leg depending from said crown and having communication at its lowermost end with the fluid space of said lowermost unit, a dome rising from the crown and having an outlet flue for discharging spent products of combustion, flues formed in the crown for establishing communication between the interior of the boiler and the said dome, a fluid outlet pipe leading from the crown, a cap about said fluid outlet pipe and detachably connected with the dome, and main feed and return pipes of a fluid system communicating with the fluid spaces.
