T 0 all whom it may concern:

Be it known that I, JUAN A. ALMIRALL, a citizen of the United States, residing in borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Heating Apparatus, of which the following is a specification.

This invention aims to provide an improved system and apparatus for heating buildings in which is utilized the exhaust steam from any available source, this steam being used to heat water which is forcibly circulated through the heating pipes; the steam being condensed and returned generally to the boiler. The exhaust steam carries a quantity of oil after its passage through the cylinders of an engine, and this oil when the waste steam is finally condensed is found to be very often of a heavy quality and otherwise objectionable, especially in feed water to the boiler. I propose therefore to use a heater which while condensing the waste steam and thereby heating water for circulating through buildings will also extract the oil or the greater part of the oil from the steam, so that the latter may safely be fed back into the boiler.

The accompanying drawings illustrate an embodiment of the invention Figure l is a diagram of the principal parts of the steam circuit and the heating apparatus. Fig. 2 is an elevation partly in section of the heater. Fig. 3 is a horizontal section on the line 3-3 of Fig. 2. Fig. 4 is a similar section on the line l4. of the same figure. Fig. 5 is a section of the upper part of the heater in a plane transverse to that of Fig. 2.

Referring to the embodiment of the invention illustrated, the heater is as a whole indicated in Fig. 1 by the letter A. The water is circulated by means of a pump B, the water being forced out of the pump through a pipe C into and through the heater A, thence by a rising pipe D to a supplementary heater A using live steam and thence to the radiators throughout the build ing from which it returns by way of the return pipe E to the pump. The heaters A and A may be separately cut out of the circuit by means of the by-passes shown.

The live steam may pass directly from the boiler K through pipe 2 to the supplementary heater and return by pipe 3 to the boiler; or any other usual or suitable method of circulating the steam may be used. The

exhaust pipe F of the engine indicated typically by the cylinder G conducts steam to the heater A having a steam exhaust J and a water drip S, the former leading to the common exhaust pipe S and the water drip S leading back to the boiler (through a force pump not shown). The steam from the engine exhaust F may be cut off from the heater A and conducted directly to the common exhaust pipe S by way of the bypass shown.

The exhaust steam from the pipe F is admitted at the top of the heater A and enters first an upper steam space M from which it passes through a number of tubes N filling the water heating space 0, the water being admitted at P and discharged at Q and constantly filling the space surrounding said tubes. The steam then passes to a lower steam space R with the exhaust outlet J previously referred to, the water of condensa tion collecting in the bottom of this steam space and running down into a water chamber T from which it is removed by the drip pipe S above referred to.

From the admission branch V at the top of the heater the steam strikes first a series of filter screens which catch the greater part of the heavy oils. These screens are supported between the top of the heater and a bottom X which is inclined downward toward the front, and which is trough-shaped in transverse section as shown in Fig. 5 so as to collect the hot oils and lead them down through an outlet Y. The bottom X of the steam filtering chamber is a substantial distance above the bottom of the upper steam chamber so as to allow free access of the steam to all the tubes N of the water heating chamber.

Between the lower steam chamber R and the water chamber T is arranged a basket of rectangular shape in plan having depending sides Z adapted to support the removable wire screens a between and upon the upper one of which is supported sawdust, coke, sea grass, or other suitable material for filtering the remaining oil or grease out of the water. In ordinary use the Water in the chamber T will stand at about the level indicated, an overflow being provided at this level as indicated at Z). The chamber T thus constitutes a reservoir for the storage of water so as to be able to supply the varying demands of the force pump which conducts the water to the boiler. A man-hole 0 is also provided in the side of the water chamber.

The entire apparatus is made very compact, strong and cheap. The outer wall is composed of a cylindrical tube in two sections (or a greater number if desired according to height) connected together by stiffening rings (Z L-shaped in cross section. The division between the upper steam chamber and the water heating chamber is formed of flanged sheets 0 j perforated to engage the ends of the tubes N. The bottom of the lower steam chamber R is a removable plate 9 resting upon a circular flange h on the inner side of the shell and carrying on its under face Z-shaped members j supporting the sides Z of the basket by means of flanges upon the upper edges of said sides, the sides Z in turn being provided with internal flanges upon which the wire screens a may be rested; and the plate 9 having its central portion apertured to permit the passage therethrough of the water formed by the condensed steam. The filter plates TV for filtering the oil from the steam at its entrance to the heater are made removable, their edges sliding in channelshaped guides Z (Fig. 3) arranged vertically within the shell of the heater. The base X of the oil filtering chamber is supported by means of short angles m fastened to the bottom of the plate X and to the inner face of the shell of the heater as shown in Figs. 2 and 5.

The exhaust steam from the engine or other steam driven unit enters the heater through the opening V and impinges against the set of screens TV TV which remove a large percentage of the oil from the steam. The steam then passes through the tubes N being partially or wholly condensed and the condensed steam drips down through the perforated plate 9 and through the filtering material on the screens a a, to the chamber T. The filtering material on the screens a a removes the balance of the oil from the condensed steam so that the water in the chamber T can be returned to the boiler and used again without harm.

There are great advantages in maintaining the steam entirely separate from the water to be heated. In filtering there is only the comparatively small quantity of water formed by the condensed steam to be provided for. Furthermore this system makes possible the separate use of the water which is heated and of the condensed steam. The latter if undesirable for returning to the boiler may be put to other uses or run otf without use, being however available in case of a failure of the supply of fresh water. The heated water is entirely uncontaminated by the oily steam and may be used for any purpose for which its composition fits it.

\Vhat I claim is l. A heater comprising a shell having a chamber at the top into which exhaust steam is admitted, means for separating oil out of said steam, an intermediate chamber through which the steam passes from said steam chamber in tubes, said intermediate chamber being adapted for circulation of water about said tubes to heat the water, a bottom cham ber in which the steam condensed by its passage through said tubes is collected and made available for feeding to the boiler, and a filter between said tubes and said water collecting chamber, above the level of the water in the latter and serving to extract oil or grease from the condensed steam.

2. A heater comprising a tubular shell having a steam chamber M at the top, filter screens TY therein and in the path of steam entering said chamber, a water heating chamber 0 below the chamber M and through which the steam passes, a chamber R below the chamber 0 and into which the steam and water of condensation pass from said water heating chamber, a water chamber T below the chamber R and constituting a reservoir for the water formed by condensation of the steam and from which the water may be returned to the boiler and. a filter Z between the chambers R and T above the level of the water in the latter and serving for extracting oil or grease from the water of condensation.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
