It has to do with the idea of back pressure, which is the resistance that fluids and gases meet as they move through a system. Back pressure is important for engineers to understand because it affects how well systems work, how much energy they use, and even how safe people are.
A back-pressure turbine with PRDs valve and dump condenser. On this system, the turbine is speed controlled and passes steam, depending on the electrical demand. The bypass-reducing valve with integral desuperheater makes up any deficiency in the steam requirements and creates an exhaust steam pressure control.
A condenser is a vital component in steam power plants, including those utilizing back pressure steam turbines, designed to enhance the efficiency of the overall thermodynamic cycle by converting steam back into water.
17 maj 2023 · The design purpose of the condenser is to improve the thermal efficiency of the unit by reducing the back pressure of the turbine [1]. In the condenser, the exhaust steam of the turbine is cooled by circulating cooling water (sea water), and the condensate is recovered as the feed water of the steam generator.
5 sty 2018 · The turbine back pressure is the important reference for the operation of the ACCs, and it can be obtained by the corresponding condensation temperature. By CFD simulation, the condensation temperature can be calculated based on the air mass flow rate, heat rejection, the average inlet air temperature and so on [9].
The backpressure is essentially the pressure of the condenser and is directly related to the condensation temperature, which depends on the ambient temperature (if an air-cooled condenser is used). According to Fig. 8 , three operating modes are distinguished.
The back pressure model of condenser is established to analyze the influence of condenser pressure and temperature on circulating water flow, circulating water temperature and suction capacity of air ejector. The dynamic control characteristics and ability of the above factors to backpressure are analyzed. 1. Introduction.
