Description

This invention relates to a power system and can be used in steam turbine condensers.

The aim of the invention is to improve the economics by preventing the formation of salt deposits in condenser tubes.

The figure shows schematically the structure of a capacitor.

The condenser comprises a housing 1 with a steam supply pipe 2, a supply pipe 3, and a cooling water outlet pipe 4, supplying and discharging water chambers 5 and 6, respectively, a bundle of heat exchanging tubes 7, a device for treating cooling water, installed in the pipe 3 and made in the form of a collector 8 with cylindrical nozzles 9 placed along the movement and connected to an external steam source (not shown), the height of the nozzles 9 decreasing along the movement of steam in the collector 8, and mounted on e nozzles 9 enlarger 10 bubbles, made in the form of plates with an adjustable angle of inclination.

The capacitor works as follows.

The steam enters through the pipe 2 to the bundle of heat exchange tubes 7, is cooled and condenses. The cooling water entering through the nozzle 3 is degassed by local heating of its individual parts to a temperature close to the saturation temperature of steam entering the steam collector 8 through nozzles 9. The fine mixture formed during degassing enters the coarsening plates 10 where due to shear stresses and a profile of the velocity of water varying over the cross section, the connection of small bubbles into large ones takes place, and the size of the bubbles depends on the angle of inclination of the plates. Next, the cooling water enriched with coarse gas bubbles enters the water chamber 5 and pipes 7, where it heats and enters chamber 6 and is removed through pipe 4. The presence of large bubbles in the water circulating through the pipes 7 increases the flow turbulization and prevents sticking of bubbles to the walls of pipes 7, which, with a reduced gas content of water, helps to prevent the formation of solid deposits.
