The objective of the current research work is to analyze the behavior of the vacuum pressure in a steam system, studying the factors that cause its reduction and therefore the limitation of the power produced in a combined cycle thermal power plant. Of these factors considered, emphasis was placed on analyzing the importance of identifying non-condensable gas (CNG) infiltrations, infiltrations is a very common problem when working at very low pressures, and then the few existing non-invasive methodologies were analyzed in order to propose corrective actions, thus avoiding the unavailability and economic loss of the generating companies. The design and type of research work is of a mixed nature, according to the scope it is descriptive and the research design is experimental. The data for the analysis were obtained from several sources, but mainly it was from SCADAT3000, Siemens software for continuous monitoring in real time and on the other hand from tests carried out in the field that allowed to have records of operating parameters, to calculate the infiltration flow of air (Kg/s) to the system, then analyze and take action based on the indicators in order to carry out a preventive control over time. The main result of the present investigation was to analyze the effects of the CNG on the vacuum pressure, calculating the air flow to verify the existence of oxygen infiltrations and in which specific place, proposing an improved methodology based on the test of the “Vaccum decay test“ applied in combined cycle plants that work with air condensers as a cooling system.
