MEANS FORUTILIZING BOILER, FURNACE, AND EXHAUST-STEAM HEAT.
SPECIFICATION forming part of Letters Patent No. 390,511, dated @ohober 2, 1888.
Application filed November 17, 1887. Serial No. 355,405. (No model.)
To all whom it may concern.-
Be it known that I, WILLIAM OLIPHANT, a c tizen of the United States, residing at Jersey City, county of Hudson, State of New Jersey, have invented certain new and useful Improvements in Means for Utilizing Boiler, Furnace, and Exhaust-Steam Heat, of which the following is a specification.
This invention relates to the indirect system of heating buildings wherein a current of hot air is passed through or into the several apartments, or to heating for any other purpose wherein a current of hot air is employed as a conveyer; and the object of the invention is to utilize aportion of the heat generated by a steamboiler furnace, otherwise not materially effective in contributing to the generation of steam, and also to utilize the remaining degree of heat of the exhaust steam from an engine or other consuming agent, especially after passage through a boiler feed-water heater of any usual type.
In order to enable others skilled in the art to which my invention appertains to understand and practice the same, I will proceed to describe the features and operation thereof in detail,-and point out in the appended claims its novel characteristics.
Referring to the accompanying drawings, Figure 1 is a general illustration of the system in diagram, and Fig. 2 a sectional plan view at a modified construction of the air-heating A is a shell tubular boiler, the furnace-gases whereof pass over a bridge'wall, B, through the hot-gas chamber 0, and in a return direc tion through the lines D to the stack.
E is the air-inlet pipe, one or several of which may be employed, admitting air, which is conducted througha chamber in the bridgewall, the latter being built hollow for the purpose, preferably, of a fire-brick shell, and thence conducted around or through chamber O by a pipe or pipes, E, or through a suitable due or fines, as E, Fig. 2, built of fire-brick or other material in the chamber-walls, and to the suction side of a blower, F, which draws and delivers the current to a further means of heating by the absorption or equalization of the predominating heat of the exhaust-steam in heating-chamber G.
The heating-chamber G consists of a shell having diaph ragms or tube-sheetsa 11, between which tubes 0 extend, the air circulating around the latter from inlet pipe H to outletpipe I, and thence to the place of heat application.
The exhaust steam from the engine or other steam-consuming agent is first passed through the feed-water heater J, entering atf and passing out at g, the type of heater herein shown representing .that more fully described by me in an application for a patent filed August 1, 1887,Serial No. 245,818, in its general features, (comprising, also, a filter, indicated at h.) At a point at any suitable distance from said heater. in the outlet-pipe g, I prefer to employ a live-steam jet, K, to accelerate the current, relieve back-pressure,and to supply additional heat to the exhaust-steam preparatory to its passage through the conducting pipe or pipes L in chamber 0, during which passage said exhaust-steam receives a final reheating, and is then delivered to compartment dof the vessel G, and passes downward through thetubes c to chamber 0, whence it is drawn (partly condensed) after heating the air surrounding said tubes to the suction-pipe M of a returning-pump N. The pump N delivers the condensed or partly condensed steam directly to the feed-watcr heater J or indirectly thereto through a suitable tank, and the same is afterward supplied (together with such additional supply of feedwater necessary) to the boiler through piper of said heater J by a suitable feed-pump. v
By the employment of this system I derive a maximum efficiency of utilizing both the unused furnace-heat and also the stored heat of the exhaust-steam subsequent to its delivery from the feed-water heating apparatus, at which period said exhaust-steam is readily superheated by either the live-steam jet or the exposure to furnace-gases, or both, and the air caused to absorb a total degree of heat exceeding that conveyed or imparted by final use of the exhaust-steam itself, as in common prac tice, for subsequent heating purposes of the class sought by the present invention.
It will be observed that either or both the pipes or fines E or L may be subdivided into a system of smaller tubes, subjecting the currents to an increased heating-surface during their transit through the chamber 0.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
1. In an apparatus for utilizing steam-boilerfurnace heat forindependent heating purposes such as specified, the combination of an airconducting fine or fines and an exhaust steanr conducting fine or fines, both located in or about the hot-gas chamber of said furnace and exposed to the heated furnace-gases at points apart from the boiler heating-surfaces, a means, as a blower, for propelling the aircurrents, a means, as a live-steam jet, for reheating and propelling the exhaust-steam current, and a heat-equalizing vessel wherein said air and said exhaust-steam are passed through a compartment and through tubes intersecting said compartment, respectively, all arranged substantially as and for the purposes specified.
2. In an apparatus for utilizing stean1-boilerfurnace heat forindependent heating purposes such as specified, the combination of an airconducting flue or fiues and an exhaust steamconducting flue or fines, both located in or about the hot-gas chamber of said furnace and exposed to the heated furnace-gases at points apart from the boiler heating-surfaces, a heat equalizing vessel wherein said air and said exhaust-steam are passed through adjacent compartments, as shown, a feed-water heater from whence said exhaust-steam is delivered to said conducting flue or dues, and a returning-pump adapted to return said exhauststeam in a condensed or partly condensed condition from said heat-equalizing vessel to said feed-water heater.
