Abstract

The invention relates to energy and can be used in power plants. The purpose of the invention is to increase reliability by reducing scale formation. The heated hydrophobic material from layer 2 is pump 11 through the steam superheater 12 and the collector 13 is fed into the water layer 4, where it is cooled, evaporates the feed water, and then returns to layer 2. In this case, the steam, washing the steam superheater 12, overheats and through pipe 8 discharged from the steam generator. Feed water by the collector 10 is dispersed into the heated layer 2. This results in the separation of gases dissolved in the feed water, which are removed through the pipe 9, and the formation of scale-forming components in the form of sludge, which is discharged through the pipe 18. Heat transfer occurs from the contact of the hydrophobic material with feed water therefore, the sludge does not settle on the walls of the casing and internals. 3 hp f-ly, 2 ill.

Description

The invention relates to energy and can be used in power plants, in industrial energy and desalination plants.

The purpose of the invention is to increase the reliability of the steam generator by reducing scale formation in it.

FIG. Shows a steam generator, general view, a variant using a hydrophobic material with a specific weight, a smaller specific weight of feed water; figure 2 is the same, a variant with the use of a hydrophobic material with a specific gravity greater than the specific gravity of the feed water.

The steam generator includes a housing 1 with lower and upper volumes, the first of which is filled with a layer 2 of hydrophobic material with a heater 3

and a layer of water 4, and the second is divided by a solid partition 5 into the steam compartment 6 and the gas compartment 7. The compartment 6 communicates with the outlet nozzle 8, and the compartment 7 - with the outlet nozzle 9 of the housing 1. In the case I there is a distribution manifold 10 of feed water .

The steam generator further comprises a pump 11 connected in series to one another, a superheater 12, and a distribution manifold 13 of a hydrophobic matter. The pump 11 is connected to the layer 2 of a hydrophobic material located throughout the entire cross section of the housing, and the steam-superheater 12 is placed in the steam compartment 6. Under the solid partition 5 there is a louver wall 14.

A hydrophobic material, such as liquid oil, is not miscible and does not react chemically with feed water. In the steam generator, a hydrophobic material with a specific gravity or a lower or greater specific gravity of feed water may be used.

When using a hydrophobic material with a specific weight less than the specific weight of feed water (see Fig. 1), the steam generator further comprises a separator 15 placed in the steam compartment 6 between the superheater 12 and layer 2 of the hydrophobic material and the distribution manifold 13 of the latter is installed in the water layer U .

When using a hydrophobic material with a specific gravity exceeding the specific gravity of water (see FIG. 2), the distribution manifold 13 of the hydrophobic material is placed in the steam compartment 6 between the steam superheater 12 and the water layer 4, and the dispensing header 10 of the feed water is installed 2 hydrophobic material

. The case has nozzles 16 and 17 for the supply and removal of a hydrophobic material and a nozzle 18 for removing sludge,

The steam generator works as follows.

The hydrophobic material in the layer 2 is heated above the saturation temperature of the heater 3, the pump 11 is directed first to the superheater 12 and then to the distribution collection

torus 13. After collector 13, a hydrophobic material in the form of a dispersed mass passes a layer 4 of water, where by contact heat exchange it gives off its heat to the feed water and brings it to a boil. After contact with feed water, the hydrophobic material returns to bed 2, where it is again heated by heater 3 to be supplied by pump 11 to the superheater 12.

The feed water by the collector 10 is dispersed into the layer 2 of the heated hydrophobic material, heated to the boiling point. In this case, gases dissolved in the feed water are separated and scale-forming components are released in the form of sludge. The gases are removed from the steam generator through compartment 7 and pipe 9, and the released sludge through pipe 18

The resulting steam contact with the hydrophobic material steam, washing the superheater 12, overheats and overheats through the compartment 6 and the nozzle 8 is removed from the steam generator.

In the proposed steam generator, scaling in the form of sludge occurs in the layer 2 of a hydrophobic material, the sludge does not settle on the walls of the housing 1 and the internals, since heat transfer occurs from the contact of the hydrophobic material with feed water.
