JOHANNES KARL RUTHS, DJ'URSHOLM, SWEDEN, ASSIGNOR T0 .AKTIEFOLAGET VAPORA CKUMULATOR, OF STOCKHOLM, SWEDEN, A CORPORATION.
ACCUMULATOR PLANT.
Application filed August 29. 1921, Serial No. 1:96:,266, and in Sweden February 10, 1916.
(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. L., 1313.)
wherein there is a variable demand for steam, particularly steam of constant pressure. My invention aims to provide a highly efiicient plant wherein a supply of heat can be made independent of the demand for steam. A further object of my invention is to accumulate heat at a low pressure. A still further object of my invention is to regulate the accumulation of heat.
Further objects of the invention will be apparent as the description proceeds.
In the accompanying drawing which illustrates my invention; Fig. 1 shows a steam generating and s'uperheating plant including an accumulator and embodying one form of my invention; and Fig. 2 shows a modified form of accumulator.
In Fig. 1, K designates an accumulator reservoir which contains a liquid having a high specific heat as, for example, oil or a salt solution. U designates a heating device which may be of any desired construction. Pump P draws liquid from the lower -part of accumulator reservoir K through conduit L and forces the same through heating device U. From heating device "U the liquid passes through conduit L" and back to the reservoir K. Conduit L eX- tends downwardly into the reservoir to the level a-a. At the top of the reservoir there is provided a valve V which serves as an inlet and outlet for air or an inert gas, the
latter being used in case air oxidizes the particular liquid used.
0 designates a steam superheater. A designates a steam generator. F designates a feed water heater. A conduit L connects conduit L and consequently the accumulator reservoir with superheater 0. Superheater 0 is connected with a pipe S within generator A. Pipe S is connected with a coil S Within feed water heater F. Coil S is connected by means of a conduit L with conduit- L and consequently with the lower part of reservoir K. Itv is thus seen that the accumulator reservoir K is coupled in parallel with the heating device and the steam generator.
The accumulator is charged as follows:
Pump P forces liquid from the bottom of the accumulator through heating device U and back into the upper part of the accumulator. The hot liquid entering the upper part of the accumulator settles on the surface of the relatively cold liquid in the lower part of the accumulator. A distinct separating surface bb will be obtained which descends during the charging period. The charging of the accumulator is completed when surface b-b has reached the bottom of the same.
The rate of flow of liquid through conduit L 1 and consequently through the heatmg device U and conduit L is controlled in such a manner that the liquid flowing into the accumulator reservior is of constant temperature. As one means for obtaining this result I have shown a valve 14; in conduit L which valve is actuated by means of a diaphragm 13 forming one side of a diaphragm chamber 12. Diaphragm chamber 12 is connected by means of tube .11 with a bulb 1O situated in conduit L Rise of temperature in conduit L causes an ex pansion of fluid contained within bulb 10 and within tube 11 and chamber 12, which expansion is transmitted to diaphragm 13 causing increase of flow through valve 14. This valve arrangement thus operates to maintain a constant temperature of fluid flowing from heating device U and into accumulator reservoir K.
The accumulator is discharged as follows:
Pump P causes liquid to flow from the upper part of the accumulator reservoir K through conduit L and into the superheater O where it gives off heat to steam within coll X. From superheater O the hot liquid passes through pipe S and heat is transferred to water in steam generator A to produce steam. The liquid then flows through coil S and thence back to the accumulator the steam is superheated. From this coil the steam passes to use through conduit It will be seen that pipe S constitutes a steam generator heating space.
During the discharge of the accumulator the separating surface bb ascends. The accumulator is wholly discharged when this surface has reached the top of the same.
Obviously the charging and discharging operations may take place simultaneously at different rates.
If the reservoir is filled with oil or the like a very high temperature (300 to 400 C. or even higher) may be obtained without a considerable increase of pressure above atmospheric. When using salt solutionsor certain acids, however, it may be more suitable, in most cases, to operate with a pressure moderately above atmospheric.
If desired, a substance which is solid at ordinary indoor temperature, such as certain fats or the like, may be used with advantage provided provision is made for melting such substance before operation. For this purpose a steam pipe R is-provided which extends through the reservoir K to melt its contents.
Fig. '2- showsan arrangement wherein accumulation is in part effected by means of solid bodies Y, for example, metal plates, stone or coal. In order to obtain a small volume of accumulator, this solid material should be so chosen that the product of its specific weight and specific heat is as great as possible. If, on the other hand, a small weight is desired, a material having a high specific heat should be chosen.
The space between bodies Y is filled with a liquid which serves to convey heat. For this purpose the substances mentioned above in connection with the accumulator of Fig. 1 may be used and, in certain cases, readily melted metals, for instance a mixture of tin and lead, may be used.
