Application filed December 13, 1902. Serial No. 135,041. (No model.)
To all whom it may concern.-
Be it known that I, EMILE ESTABLIE, civil engineer, a citizen of the Republic of France, and a resident of 11-13 QuaiValmy, Paris, in
the Republic of France, have invented oer-- tain new and useful Improvements in Vertical Steam-Generators, of which the following is a specification. 1
This invention relates to improvements in vertical steam-generators having a fire-box with metallic walls surrounded by the water and boiler-tubes extending vertically from the fire-box through the mass of water. The object of these improvements is to provide in that class of steam-generators means for thoroughly cleaning the walls of the fire-box by preventing the mud contained in the water from leaving deposits on said walls.
The improvements consist in surrounding the boiler-tubes by jacket-tubes, which extend upward beyond the highest water-level, which rest by their lower edge on the top of the fire-box, and which are provided at their lower end with very thin slots extending through the whole thickness and to a small height of said tubes. They further consist in supplying the boiler with a water-injection tangential to the cylindrical fire-box and leading to-the annular portion between the fire-box and the outer wall of the boiler. By the combination of these two arrangements the thorough cleaning of the walls of the tirebox is assured. I In fact, the water can only enter the space provided between the boilertubes and their jackets by passing through the thin slots of said jackets, which slot-s, besides, stop the mud. The small quantity of water which passes thus by the slots of each jacket is vaporized instantaneously as it arrives in contact with the boiler-tube, which is continuously kept at a very high temperature. This sudden vaporization acts like a small explosion and increases during a very short time the pressure at the base of the jacket-tube, which pressure produces steamjets from inside the tube to outside through the slots of said tube and assures thus a horizontal chase, which forces laterally the mud which has not been free to pass through these slots and prevents it from being deposed at the top of the fire-box. This mud falls into the annular portion of the boiler 1 which surrounds the fire-box and is carried away by the continuous rotary motion of the water produced in this portion by the tangential supply of water, which has for result to prevent said mud from leavingdepositson the side walls of the fire-box. thus continuously moved and is gathered while it continues turningat the bottom of the annular space, from where it can be evacuated when desired by means of a discharge-valve.
In the accompanying drawings, Figure 1 is a sectional view of a boiler incorporating my invention. Fig. 2 is a cross-section through the fire-box. Figs. 8 and 4 show an elevation and a horizontal section of a boiler-tube and its jacket-tube.
The boiler comprises, essentially, a cylindrical exterior shell a, a concentric fire-box b with metallic walls, a'group of tubes, a smoke-box c, and a water-supply system. The group of tubes is formed of boiler-tubes d with internal wings and jacket-tubes f. These jacket-tubes extend upward beyond the water-level and rest by their smooth lower edge on the top of the fire-box. They are provided around their periphery, from their lower end to a small distance above, with saw-notches or very thin slots so, through which the water can penetrate into 'the annular spaces exist ing between. the tubes and their jackets. The water will enter by intermittence, be cause each entrance causes a sudden vaporization which produces a thrust from inside to outside, as it has been explained.
The water-feeding system of the boiler comprises, essentially, a feeding-pipe ij, which leads tangentially to th e-ifirebox in the an nular space 12, surrounding said fire -hox.
The movement of'the water inthis pipe is assured by the injector s, to which leads the steam-pipe 1 and the water-snction conduit 2. This tangential feeding carries away the mud, as already explained, by a continuous rotary motion in the space 41 until it is evacuated by the discharge-valve 8.
With this class of boiler no deposit can ever be left on the walls of the fire-box, and all the disadvantages arising from said deposits are obviated.
