APPARATUS FOR REG-ENERA'I'IN G STEAM Specification of Letters Patent.

Patented May 13, 1913.

Application filed February 5, 1910. Serial No. 542,253.

To all whom it may concern Be it known that I, RICHARD H. STEVENS, of Munhall, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Apparatus for Regenerating Steam, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specification, in which-- Figure l is a sectional elevation of apparatus constructed and arranged in accordaiu'e with my invention. Fig. 2 is a sectional plan of the same on their-regular line li it of Fig. 1.

My invention relates to the regeneration of SlQttll'l and the object of the invention is to provide an improved apparatus for etl'ecting the exchange of heat between a body of steam and of water whereby an intermittent supply of high pressure steam is utilized to provide a continuous supply of low pressure steam and a body of water is employed to storc'the heat of the high pressure steam when the supply of high pressure steam exceeds the demand of low pressure steam, and

to :lurnish the heat necessary to supply a constant supply of low pressure steam when the dei'nand exceeds the supply of low pressure steam.

A further object of the invention is to provide improved apparatus by which the steam and water are caused to circulate within the regenerator and the steam passing into and thro ugh the regenerator is brought into intimate contact with the water contained in the regenerator.

In the drawings, 2 represents a regencrator chamber having an inlet pipe 3 by which steam is led into the regenerator from the exhaust of a steam engine or other source of steam, and 4 is an outlet pipe through which steam is led from the regcaicrator 2 to a turbine or other "ow pres sure power unit in which the regenerated steam is utilized.

As shown in the drawings, the steam inlet 3 is connected with the upper end of a cylindrical compartment 5 located in the. interior of the regenerator 2 and having an open lower end. The compartment 5 is surrounded by an annular chamber (5 which has closed upper and lower ends. The wall of the chamber 6 adjacent to the lower end of the chamber is provided with a series of small openings 7 by which water or other fluid can pass into or out of the chamber before being put into the chamber 2 into the chamber 6, in order to restore the levels of the wat'erin the two chambers.

At the upper end of the partition t'orming the compartnumt 6 is a series of branch outlet openings 8 by which communication is a tl'orded between the compartment 6 and the sin'roinuling regencrator chamb at a height above the level of the water main tained in the regmierator chamber 2. The chamber 22 is divided by a cylindrical or tubu lar partition 9 into two compartments and, the lower end ot the wall 9 is provided with an annular water trough 10 having a multiplicity of small holes or openings 10 in its bot om through which water is kept eonstantly flowing in a large number of small streams. The inner compartment formed by the partition wall 9 in the regenerator chamber 2 is connected by the extension 11 with the outlet pipe 4, as is clearly shown in Fig. 1.

13 reprcsents'the overflow pipe by which the body of water maintained at a predetel-mined level in the chamber 2, and 14 is a water inletpipe by 'which water is supplied to the regenerator, the supply being controlled by the valve It. A relief the 15 is provided on the upper end 0f the connection leading from the inlet pipe 3 to the inner chamber 5 of the regcnerator by which the pressure in the chamber 2 is relieved when excetaling a. predetermined amount.

in using apparatus like that shown in the drawings, the regenerator is supplied with a body oi" water, which is prel'erably heated The relief valve 15 is then closed and steam is supplied to the regenorat'm' throughthe inlet pipe 2' The incoming steam passes from the pipe S into the enlarged clnunber and causes the water in the chamber 6 to rise and flow through the outlets 9 into the annular spraying trough It). The steam also passes downwiu'dly through the pipe 5 and upwardly through the chamber (3 formed by the cmlcenlric walls of the chambers 5 and 6 and then passes outwardly through the branch pipe 8 into the regcne 'ator 2, as is indicated by the arrows. The steam, on its entry into the chamber 2, passes over the surface of the water in the annular trough 10 and is directed and caused to pass under this trough and through the large number of small streams o'l water whlch are flowing through from the perforations 10* in the bottom of the trough l0 and then passes upwardly through the annular passage 4 formed between thewalls of the chamber 6 of the water and the steam is rendered substantially equal in the chamber 2. When the steam required by thelow pressure unit connected to the outlet pipe 4 of the regenerator exceeds the supply, the heated water in the chamber 2 will vaporize and will give up in'the form of steam enough steam to form a substantially constant supply."

By the use of my-lmprovedapparatus the fluid is broken up into a multiplicity of fine streams and, owing to the large surface of the fluid brought into contact withv the steam, causes a very intimate mixture of the two, which results in the sought for increase in the interchange of heat.

Modifications in thepconstruction and arrangement of the apparatus may be made without departing from my invention.
