Operation Experience and Analysis of the Efficiency of K-220-44 Turbine with a Ball Cleaning System in the Condensers.

摘要

A ball cleaning installation, manufactured by GEA, FRG has been in operation since 1983 at Kozloduj in the condensers of turbine no. 8, Unit 4. In order to evaluate the effectiveness of the system, the vacuum in the condensers of turbines 8 and 7 (at the same unit) are compared. It is found that the vacuum in the condensers with ball cleaning is higher by 2.28% in the average, resulting in 8.80 MW increase in the turbine power output. This result is very satisfactory and installing of the Bulgarian made ball cleaning systems for all the plant units will start by the end of 1987. (Atomindex citation 19:072664)
