APPARATUS FOR CLEANSING STEAM AND HEATING- WATER.
, Steam and Heating Water, of which the following is a specification.
This invention relates to apparatus for cleansing steam and heating water and 1s particularly suitable for use on 'steamships for heating boiler feed water by means of steam, as for example the exhaust steam from auxiliary engines. 4
The object of theinvention is to provide improved steam'cleansing and water heating apparatus whereby the steam can be cleansed and the water heated in a more efficient manner than heretofore usual and the weight of the apparatus reduced.
For these purposes the invention consists in novel constructions and combinations and arrangements of=parts, all 'as hereinafter described and pointed out in the claims. v
Inthe accompanying illustrative drawings, Figure 1 is a sectional elevation on the line A-A of Fig. 2, Fig. 2 is a sectional plan view on line BB of Fig. 1, and Fig. 3 is a part sectional elevation on the line CC of Fig. 2, showing steam cleansing and water heating apparatus according to the invention.
Referring to Figs. 1, 2 and 3, a is a cylindrical water heating vessel having an inlet branch I) through which the water (hereinafter called feed water) to-be heated is forced to flow past a spring loaded inlet j valve 0 into the interior d of the vessel. In this vessel the water falls throughv a spraying device 6 and through the heating steam, into a chamber f which is provided with an outlet 2'. The chamber f may contain a float 9 arranged to operate a valve h for controlling, in a well known way, the supply of steam to a feed pump for withdrawing the heated feed water from the chamber f} through the outlet 2'.
Around the heating vessel a is a wall a arranged to form with the vessel a an annular passage j-provided with oil collectors k, the passage being so arranged that the steam entering it at one end through the branch Z is constrained to flow around the passage to the partition m at the other end thereof and thence through an opening n into the heating vessel 0 Specification of Letters Patent.

Application filed January 23, 1912. Serial No. 672,942.
' apparatus are favorably afiected. The path of steam flow through the cleanser being circular, in the example described, also piomotes the deposition of liquid particles from the steam by centrifugal action, while the velocity of flow is also maintained by reason of the length and relative narrowness of the passage 7'.
The oil collectors k in the arrangement illustrated, consist of angle bars vertically disposed, arranged at intervals and attached to bands 0 which are secured to the inner and outer walls of the passage j in such a manner that they canbe easily withdrawn from the apparatus for inspection or clean ing on removal of the cover 10. The oil deposited on the angle bars la drains to the base of the passage j where it collects, to gether with water of condensation and flows into a well 9 which is arranged adjacent to the end wall m of the passage j and is divided into two compartments 8 andu by a partition 7 so that the float oil is retained in the compartment 8 for periodic removal through a cock t while the water may be continually discharged from the compartment u 'by a cock 2).
Although not shown it will be understood that the apparatus is to be provided with the usual fittings including an air valve, relief valve, and pressure gages.
What I claim is i .1. In apparatus for cleansing steam and heating water, the combination with a water heating chamber having an inlet for water at the top and an outlet for heatedflwater at the bottom of an oil and water separating chamber arranged around said water heating chamber, said separating chamber having a tangentially arranged steam inlet forming a continuation of said chamber at its outer end, a steam outlet at its inner end communicating directly with the interior of said water heating chamber below said water inlet, an exit at its lower end for separated water and oil, and a wall arranged between said steam inlet and outlet whereby steam is constrained to flow horizontally in one direction only around and within said separating chamber to the outlet therefrom and thence into said heating chamber,
, heating chamber having an inlet for water at its upper end and an outlet for heated water at its lower end of an oil and water separating chamber arranged around said 1 water heating chamber, closed at its upper and lower ends and having a tangentially arranged inlet for steam at its outer end, a lateral outlet for steam at its inner end formed in its inner wall between the upper and lower ends thereof and opening directly into the water heating chamber below the water inlet, a wall arranged between and separating the lateral 'inlet and outlet for steam and a lower outlet for separated oil and water. v
3. In apparatus for cleansing steam and heating water, the combination with a water heating chamber having aninlet for Water at its upper end and an outlet for water at its lower end of an oil and water separating v chamber arranged around said water heating chamber, closed at its upper and lower ends, having a tangentially arranged inlet for steam, a wall separating the inner end of said oil and water separating chamber from the tangentially arranged inlet for steam, a lateral outlet for steam extending through the wall of said water heating chamber adjacent to said first mentioned wall and an exit for separated oil and water. 4
4. Apparatus for cleansing steam and heating water comprising a water heating chamber having an inlet for water at the top and an outlet for heated water at the bottom, a receptacle for heated water below said heating chamber and an oil and water separating chamber arranged around the water heating chamber, said separating chamber being closed at top and bottom, having a tangentially arranged inlet for steam, a vertical wall adjacent to said tangentially arranged inlet and closing the inner end of said chamber, a lateral outlet adjacent to said wall and communicating with the water heating chamber between the top and bottom thereof and an exit at the bottom for separated oil and water.
5.,Apparatus for cleansing steam and heating water comprising a water heating chamber having a'valved water inlet at the top, a receptacle for heated water at the bottom, and a lateral inlet for steam between its top and bottom and an oil and water separating chamber closed at top and bottom, encircling said water heating chamber, having a tangentially arranged inlet for steam, a vertical wall arranged adjacent to the lateral steam inlet to said heating chamher and separating said inlet from the tangentially arranged steam inlet to said separating chamber, a receptacle for separated oil and water arranged at the bottom of said separating chamber adjacent to said partition and a water distributing device arranged Within said water heating chamber opposite the lateral steam inlet thereof.
