“…Equation (27) can be re-arranged to determine the frictional component of the pressure drop as follows; DP frict ¼ DP meas À DP mom À DP st (28) where the momentum pressure loss/recovery, DP mom , and static pressure loss, DP st , need to be evaluated in order to determine frictional losses. The momentum pressure loss/recovery reflects the change in kinetic energy of the fluid continuum.…”

“…In 1984, Eskom ordered air-cooled condensers for the Majuba power plant (6 x 660 MWe). It was then put into operation in 1996 and of the six units in the power plant, only three units were finally equipped with air-cooled condensers [8].…”

This paper summarizes the knowledge and results obtained in the field of designing technological platforms for energy industry. Optimal solution of the layout of elements and material of a number of technological platforms with a specific number of modules was searched. Technological platforms are the main supporting structure of the air-cooled condensers (ACC), which ensure cooling of plants. The fundament of the solution is based on the schema that the platform is composed from the at least one standardized bed containing the supporting surface equipped with the supporting columns and at least one horizontal segment for the condenser exchanger support. The platform structure must ensure sufficient spatial rigidity and stability and ACC functionality. Design requirements are defined both by size and weight of each single module of condenser and the total number of modules in assembly.

“…Du et al [28] found that the heat transfer coefficient of steam condensation inside a copper tube remains virtually constant with the increasing steam velocity at the tail of the tube, which has a diameter of 25 mm and temperature difference equal to two degrees between the saturated steam the coolant media. OˊDonovan et al [29] submitted a thermal analysis to determine the outputs of erecting an ACC in concentrated solar power. Steam condenser temperature and correspondence pressure have been measured as a function of fan speed, which varied (changing the air volumetric flow rates) at steam mass flow rates.…”

The steam condensation process has been experimentally investigated in an air-cooled condenser (ACC). The ACC has been designed and built using a flattened cross-section horizontal tube. The flattened tube has an internal dimension of 102 mm x 12 mm with 4030 mm length. A range of vacuum operating conditions are applied to operate the ACC. In the experiments, parameters such as vacuum pressure, saturated temperature, wall tube temperature, rate of heat transfer, and local average steam heat transfer coefficient have been considered along the flow direction with the variation of cooling water temperature. The experimental results revealed that the steam saturated temperature and the related pressure decrease with the reduction of the cooling water temperature, and the temperatures of the upper and lower parts of the horizontal flattened tube. The results also showed that the local steam condensation heat transfer coefficient decreases along with the direction of the flow, but it there is incrementing with the decreasing of saturated steam temperature at a certain range of cooling water temperature.
