Description

-h

pressed against the mouths of the tubes P by means of springs with efforts that cause certain pressures in the evaporators, decreasing as the evaporator of the boiler 4 is transferred to the nearest evaporator b, from it to the next, etc. The solution is concentrated in the evaporator 3 through pipes 33 from the evaporator - boiler 4 to the nearest evaporator 6, from it to the next evaporator 6, etc.

In evaporators, the level of the concentrated solution can be maintained automatically, for example, by means of floats 34.

In the last evaporator 6 (left on

drawing) the solution receives the highest

concentration and from here comes by

pipe 35 into the cavity 77 preheater 2.

Steam generated in the latter

evaporator 6, can be used

directly for heating.

The drawing shows an exemplary use of this steam for the final heating of the heated medium. Steam through pipe 5 (5 enters cavity 57 of heater 2 between grids 22 and 25, where it condenses on the outer surface of pipes 16; from cavity 57, condensate flows through pipe 38 into the regulator box 10, from where all incoming condensate flows through pipe 39 - In the boiler 7 low pressure.

Due to the evaporation of condensate in the main part 75 of the boiler 7, the concentration of the working fluid solution 14 in the boiler 7 will be greater than in the flowing condensate. A certain constant concentration of the solution in the boiler 7 can be obtained permanently by removing part of this solution from it, which is achieved by transferring the most concentrated solution 14 at the bottom to the compartment 41 of the boiler 7, and from compartment 41 through the channel 42 to compartment 43. In the separations of boiler 41 and 43, due to the evaporation of water, increase the concentration of the solution to approximately the concentration of the solution flowing through pipe 29.

 Since to obtain a pair of the same -elasticity from more concentrated

the solution requires a higher temperature; The boiler room 43 and 41 can be heated by combustion products coming out of pipe 44 of the boiler evaporator 4. In the cases of heating buildings with heated air, the compartment- / 7 of the boiler J / can be heated with air extracted from heated heater.

From the boiler compartment 43 / the solution can be continuously or periodically pumped 52 to the evaporator, the boiler - / through the pipe 45.

To remove air from the entire system, the spirit is a vacuum pump 46, sucking air mixed with steam from preheater 2 through pipes 47 and 48.

The subject matter of the invention.
