Specification of Letters Patent.
= PatentedAug. 14, L966.
Application'filed November 2,-:190,4.':--Seria1 No. 231,135.
To all 111720711, it may concern.-
Be it known that I, ANDREW BOLTON, a sub ect of the King of Great Britain and Ireland, residing at 49 Deansgate, Manchester,-
in the county of Lancaster, England, have invented a new and useful Improved Apparatus for Superheating Steam, of which the following is a specification.
This invention relates to that class of ap paratus used for superheating steam, generally known as field-tube. superheaters, wherein the steam from the boiler passes through a box or chamber containing a series of inner vertical tubes open at both ends, which are placed inside other or outer tubes open at their upper ends and closed at their lower ends, such tubes being suspended inside the downcast flue or the upcast flue of a Cornish or other suitable boiler, whereby the steam in passing through such tubes becomes superheated on its passage to the engine.
The manner in which my said invention is to be performed or carried into practical effeet will be readily understood on reference to the two sheets of illustrative drawings hereunto annexed and the following explanation thereof.
Figure 1 on the drawings is a vertical section of a superheater constructed with an arched diaphragm dividing the outer box into three chambers according to my said improvements. Fig. 2 is a similar view of a slight modification thereof hereinafter more particularly described. Figs. 3, 4, and 5 are horizontal sections showing diflerent arrangements of the field-tubes. Fig. 6 is a vertical section showing the diaphragm made in the form of an inverted arch; and Fig. 7 is a similar view of a further modification of the same, embracing a combination in which a double arched diaphragm is employed.
According to my present improvements, the flanged outer box a is divided by an arched diaphragm 1) into three compartments 0, d, and e. Two of these chambers c and e act, respectively, as inlet and outlet chambers for the steam to and from the superheater, and the third chamber at acts as an intermediate chamber. Through the diaphragm b I drill holes and insert therein inner tubes f, open at both ends, and I drill corresponding holes in the tube plate or bottom of the box a, (but of larger diameter,) and I insert therein tubes 9, which are closed at their lower ends and surround the inner tubes f so as to leave annular spaces-between them. Imake each-row of tubes in graduations of different diameters, as shown at Figs. 3, 4, and 5, and (by preference) I place the larger tubes behind the smaller ones, either in a direct line, as shown at Fig. 3, or zigzagged, as shown at Figs. 4 and 5.
The consequence of the above-described construction of arched diaphragm and tubes is to divide the superheating-tubes into two or more groups. The steam admitted to the inlet-chamber c circulates through the first set of tubes to the intermediate chamber (1 and in turn or series through the second set of tubes to the outlet-chamber e, which it enters-in a superheated state, and by placing smaller tubes in front of the larger tubes, as shown at Figs. 3, 4, and 5, their heating-surfaces are better exposed to the hot gases in the flue.
The arrows on the various views show the direction in which the steam circulates through the three chambers 0, (Z, and e successively by means of the respective arrangements of the field-tubes according to my invention. In Figs. 1 and 2 the steam passes from the inlet-chamber c first down one set of inner tubesf and up the corresponding outer tubes 9 to the intermediate chamber at and thence down the second set of outer tubes and up the inner tubes to the outlet-chamber e, and in Figs. 6 and 7 this order is reversed, the steam passing first down the first set of outer tubes and up the corresponding inner tubes into the intermediate chamber d and thence down the second set of inner tubes and up the corresponding outer tubes into the outlet-chamber e.
I claim as my invention- 1. An apparatus for superheating steam,
comprising an outer flanged box, and an arched diaphragm dividing said box into three compartments with communicating tubes.
2. An apparatus for superheating steam, comprising an outer flanged box, and an arched diaphragm dividing said box into three compartments, inlet and outlet compartrnents and an intermediate compartment, with communicating tubes, one within another.
3. An apparatus for superheating steam, comprising an outer flanged box, and an arched diaphragm dividing said box into three compartments with communicating tubes, in combination with means connecting IIO said compartments, said means consisting of eters, the larger tubes arranged zigzag behind a graduated series of tubes of different diamthe smaller ones.
eters. In testimony whereof I have signed my 4. An apparatus for superheating steam, name to this specification in the presence of comprising an outer flanged box, and an two subscribing witnesses.
