Proposal Method for Assessment Evaluation of Air Cooled Condenser Used in a Biomass Power Plant of Cuba

Abstract

At present day, the use of Air Cooled Condenser (ACC) in power plants is a trend in regions with difficult access to water. In the available literature the performance analysis of the ACC is a difficult task, because not have an only method that includes all of the elements related to the ACC's use and his effect on the power plant. The Kröger's method is recognized as the more effective for the thermal analysis of the ACC, but this procedure not offer satisfactory results for elevated values of environmental temperature, as it is the case of Cuba. In the present work is developed a unique method of analysis that considers the effect of the environmental variables on the ACC, allowing obtaining its final effect on the condenser facilities. The new proposal follows the same logical order shown in the Kröger's method, since it is the one with the greatest acceptance and dissemination among researchers and specialists working in this field. In this new method are considered news procedures for the estimation of the average heat transfer coefficient, pressure drop and thermal assessment.
