NrrED STATES PATENT OFFICE.
JEAN BONICARD, OF PARIS, FRANCE.
STEAM GENERATOR AND SUPERHEATER.
SPECIFICATION forming part of Letters Patent No. 507,644, dated October 31, 1893.
Application filed June 24,1893- Serial No. 478,701- (No model.) Patented in France February 23, 1893, No. 228,165, and in England June 1, 1893, No. 10,759.
To all whom, it may concern.-
Be it. known that I, JEAN BONIOARD, a citizen of the French Republic, and a resident of No. 37 Rue Bouret, Paris, France, have invented certain Improvements in Steam Generators and Superheaters, (for which patents have been granted in France, No. 228,165, dated February 23, 1893, and in Great Britain, No. 10,759, dated June 1, 1893,) of which the following is a specification.
My invention relates to the class of steam generators which have connected with them suitable superheaters for the steam, interposed between the outlet for the saturated or ordinary steam and the service steam pipe.
My invention resides mainly in the superheater.
In the annexed drawings I have shown. an embodiment of my invention Figure 1 being a Vertical mid-section of the generator and superheater in the plane indicated by the line 1, 1, in Fig. 2, and Fig. 2 is an elevation, except as to the lower part, which is in section in the plane indicated by the line 2, 2, in Fig. 1.
X represents an outer casing in the base of which is constructed the furnace F.
The steam generator comprises a lower or water chamber A, and an upper or steam chamber B. These chambers are connected by tubes T, and by a drum or casing W. The hot products of combustion pass up through tubes E, which extend through the chamber A, and circulate among the tubes T, within the casing W, passing off through a chimney V, which taps the casing W. Water is supplied to the chamber A of the generator by a supply pipe O, and the saturated steam finds an outlet from the chamber B at a pipe D. This construction insures a rapid evaporation of the Water, and the steam generated passes through the outlet pipe D down through a pipe G, and thence to a superheater in the fire-box of the furnace by a pipe G The superheater comprises a strong and tight drum or chamber K, which is connected at one end with the steam-inlet pipe G and at the other end with the steam supply pipe L, which leads the superheated steam to the engine, or to any required point for use. In the pipe G is a check valve g, which prevents the superheated steam from passing back to the chamber or section B of the generator. In starting up the furnace, however, if there should be Water of condensation in the superheating drum K, it will first feel the effect of the heat and be converted into steam, and in order to allow this steam to pass into the chamber B, I provide the by-pipe Q, which connects with the pipe G at its extremities in a way to bridge over the check valve g. In this pipe Q, is a manually operated cut-off valve R. The drum K, of the superheater has a jacket M in the form of a cylinder provided with tubular journals t, through which the respective pipes GP and L pass, said pipes forming bearings about which the jacket M- may turn. One of the journals t is furnished with a hand-wheel P, by which the jacket may be conveniently turned. The jacket is open along one side, as seen at O in Fig. 2, and there is an annular space between the drum K and its jacket M, through which may circulate the hot gases from the furnace, which enter at the opening 0. By rotating the jacket M so as to bring the opening 0 more or less nearly toward the lower side, so as to expose the drum K more or less directly to the flames of the furnace, the pressure of the steam in the superheater may be regulated. The jacket M is in the nature of a shield to protect the superheating chamber more or less from the direct action of the flame and heat.
The generator may be arranged either vertically or horizontally and is so constructed that it can be readily dismantled for cleaning or repairs. It is not liable to explosion, and is sufficient to generate asteam tension in the chamber B of from one to two kilograms; when led into the superheater, the steam tenfive kilograms, this tension being controllable by the shifting or rotation of the jacket or shield M.
An economy of thirty to thirty-five per cent. in fuel may be attained by the use of the superheater, and it also enables a comparatively small generator to be used.
Having thus described my invention, I
, claim-- 1. The combination with a steam generator and its furnace, of a superheating chamber 'sion may be increased to from five to twentyfor the steam, situated in the furnace and connected on the one side with thesteam outlet of the generator, and on the other side with the supply pipe for the superheated steam, and a movable shield or jacket about said superheating chamber, adapted for shielding the latter to a greater or less extent from the direct action of the flames, as may be desired.
2. The combination with a steam generator and its furnace, of a superheating chamber situated in the furnace above the fire-bed, and connected on the one side with the steam outlet of the generator, and on the other side with the supply pipe for superheated steam, and the rotative jacket M, about said chamher, said jacket having an opening 0 for the admission of the hot gases to the jacket space and journals to support it rotatively.
3. The combination with-a steam generator and its furnace, of the horizontally arranged chamber K, situated in the upper part of the furnace and connected at its respective ends with the pipes G and L, the former of which connects with the steam outlet of the generator, the said pipes, the jacket M, which houses the chamber K, and has an opening 0 for the admission of the furnace gases, the tubular journals 6, of said jacket through which the respective pipes GX and L extend, and the hand-wheel P, on one of the journals t, substantially as set forth.
4. The combination with a steam generator and its furnace, of the steam outlet pipe D, the pipe G the pipeG connecting the pipes D and G, the check-valve g, in the pipe G, the by-pipe Q, connected at its extremities with the pipe Gand bridging the check-valve, a valve R in the pipe Q, a superheater in the furnace connected with the pipe G" at its receiving end, and the supply pipe for superheated steam connected with the superheater, substantially as set forth.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
JEAN BONIOARD.
