By condensing the vapors before sending the stream on to the next stage, the vapor load is reduced. Ejectors with suction pressures below 1mm.
Good afternoon, I am now trying to calculate a steam ejector for vacuum production. corresponds to each ejector’s air consumption. The shell-and-tube ejec-tor condenser reduces load on the downstream ejector, which reduces overall motive steam consumption. steam production rate is reduced, then maintenance costs should more properly be considered to be variable. There are distinguished by critical back pressure and break down back The accuracy of the condensation model is confirmed in this section, and the significance of considering the NEC in steam ejector is reiterated, providing a theoretical foundation for investigating two-phase heat transfer in the steam ejector, as well as energy consumption and exergy destruction in the ejector pump refrigeration system. The theory behind the Steam Jet Ejector For rough estimation of an ejector’s steam consumption, one can simply use the following equation: 9 Ra = >Pd (0. Vacuum Producers: Ejector-based systems are particularly appropriate as primary vacuum producers, particularly where motive steam is almost always available. Experi mental verif~cation of these relat~ons is included.
However, if the manufacturer of steam-using equipment has specified the amount of steam pressure and steam consumption for their equipment, these values should be used in the calculations. High pressure is admitted to a nozzle A that sends a jet of very high velocity into throat of a venturi. In most of the cases, multi nozzle ejectors designed for the same conditions usually reduce steam consumption by 10% to 15% as compared to Single Nozzle Ejector.
