Introduction

 Ecological safety of electrical energy generation largely depends on operating conditions of the low-potential part of TPP, possibility of forming a deep vacuum in the condenser, possibility of reliable and environmentally safe operation of the condensing installation.

6.4.1. Analysis of application of air condensers in power industry

Analyses of design and features of air condensers operation

For a long period of time air condensers (AC) were used only for steam turbines of low capacity – from 1 to 15 MW. An air condenser for a turbine of higher capacity (160 MW) was for the first time applied at Utrillas TPP, constructed in 1970 in a water-short region of Spain. The condenser was manufactured by GEA company (Germany).

6.4.2. Analyses of new design of air condensers

Klevtsov A.V., Pronin V.A.; MPEI (TU)

Analyses of experience in application of air condensers (ACs), produced by the leading world manufactures shows that development of their designs was focused on one direction - elimination of design defects. The published information on technical characteristics testifies that average heat transfer coefficient of various AC designs significantly differs.

6.4.3. New generation air condensers (NGAC)

Klevtsov A.V., Pronin V.A.; MPEI (TU)

In recent years the efforts of researchers have been directed to improvement of air condensers design; however, AC drawbacks, listed above, are not eliminated until now. In this connection a search of new ways of the condensation process arrangement, and intensification of heat exchange from cooling air side, remain actual.

6.4.4. Design of effective configurations of tube bundles of new generation air condensers (NGACs)

Klevtsov A.V., Pronin V.A.; MPEI (TU)

Intensity of transfer processes at flow and heat exchange in transversally washed bundles depends on many factors both regime, and geometrical. For this reason working out and research of new configurations is usually carried out, using a number of approaches. The majority of these approaches is directed to improvement of characteristics of already known configurations.

6.4.5. Cost-effectiveness analysis of air condensers application

Klevtsov A.V., Pronin V.A.; MPEI (TU)

 Cost-effectiveness of new equipment introduction is determined by comparing of new and base alternatives. For the base alternative (1) we will take surface condenser (with wet water cooling tower) of turbine T-250/300-240, and for the new one (2) – air condenser (AC) under development is taken.
