The inventive ozone generator comprises at least one tubular external electrode (), at least one internal electrode (), wherein each internal electrode consists of a plurality of tubular metal segments () which are closed at least partially at each end and externally ceramic-coated, said tubular segments are disposed one behind another, mechanically de-coupled from each other and electrically connected, a rod () axially crosses the tubular segments () and is provided on the end thereof with means () for axially clamping the tubular segments to each other in such a way that an electric contact is formed. Each tubular metal segment () is provided at each end thereof with an outwardly convex bottom () which is embodied substantially in the form of a spherical cap, comprises a central area () for electric contact and is provided with a ceramic coating () consisting of at least two thin layers ().

Ozone generator and an electrode thereof

A flow control apparatus for enriching gas containing oxygen with ozone includes a generator for producing the enriched mixture. A flow meter is connected to the generator outlet to measure the flow of the generated enriched gas. A mass flow control device is connected downstream of the flow meter. A flow control comparator compares a flow value as obtained from the measuring means and a preset constant value. A signal output of the flow control comparator is connected to a signal input of the mass flow control device for varying the mass flow in accordance with the comparison. An outlet of the mass flow control device is connected to an inlet of a compressor for compressing gas, the inlet gas pressure varying to keep compressed gas at a constant pressure. Feedback is provided between an outlet and an inlet of the compressor. A second mass control device is intermediately connected along the feedback connection for adjusting the mass flow of gas passing through the feedback means. A pressure control comparator compares the inlet pressure of the compressor to a second preset constant value. A signal output of the pressure control device is connected to a signal input of the mass flow control device for varying the mass flow being fedback in accordance with the comparison. The flow controlled compressed gas is delivered to a reactor at a constant pressure.

Ozone enriched process gas

In ozone generators having segmented inner electrodes (7), the electric connection of the segments is effected by means of plane contact areas (10) applied to the ends of the segments. A tension rod (11) passing through all segments ensures cohesion and, at the same time, is used as the connecting element for supplying the ozone generator with power.

Device for generating ozone

In a process for purifying and deaerating the feed water line in the circulation system of a power-generating plant heated by nuclear power, the following steps are carried out in order to solve acute problems of steam-generator corrosion:

Process for purifying and deaerating the condensate/feed water in the

In a feed water preheater of horizontal type with an integrated desuperheater, the last deflection chamber of the desuperheater is provided with lateral steam outlet ports (13). As a result, the desuperheated steam does not reach the condensation zone directly as hitherto by passing into the free cross-section of the tube bundle but, instead, it passes into the free space surrounding the condensation bundle (2) on which it can then act from the outside inwards at minimum flow velocity.

Feed water preheater

In order to reduce the difference in stress of the tubes through which heating steam is flowing in the case of heat exchangers where the tubes are concentrated in at least two horizontal bundles and where heating steam flows through the tubes and a power medium flows around the tubes, it is proposed that there are arranged at the intake openings of the tubes (1) through which the heating steam is flowing baffles (3) with different intake profiles (4) in such manner that within each bundle of tubes the intake profiles (4) will become smaller in direction of flow of the power medium to be heated.
