    the saturation pressure of the cooling water. An intercondenser, however, increases the initial cost of an ejector. It must be determined, therefore, whether or not the additional expense of an intercondenser is worth the savings that will be forthcoming in steam economy. Small ejectors for pilot plants, laboratory use or intermittent service may not warrant intercon-densing. As many as 4 or 5

  • EJECTOR REFRIGERATION SYSTEMS Description of technology

    Ejector or jet pump refrigeration is a thermally driven technology that has been used for cooling applications for many years. In their present state of development they have a much lower COP than vapour compression systems but offer advantages of simplicity and no moving parts. Their greatest advantage is their capability to produce refrigeration using waste heat or solar energy as a heat

  • Steam Ejector Used as a Substitute for Cooling Tower in

    ejector is proposed for the fermentation cooling of a typical Brazilian sugar and ethanol production plant. The steam which feeds the steam ejector is obtained from the plant utilities and the low temperature obtained from steam expansion within the ejector is used for sugar cane fermentation process cooling. The steam ejector discharge heat is recovered as it is used to sugar and ethanol

  • Understanding ejector systems necessary to troubleshoot

    ejector. Cooling water conditions A rise in cooling-water temperature lowers the available log mean temperature difference (LMTD) of a condenser. Should this occur, the condenser will not condense enough steam and condensible hydrocarbons. This will increase the vapor load to the downstream ejector. As a result of inadequate condensation, there also is an increase in pressure drop across the

  • Steam Ejector Fundamentals: An Alternative to Vacuum

    Ejector Design. Very simply, an ejector is a pumping device. It has no moving parts. Instead, it uses a fluid or gas as a motive force. Very often, the motive fluid is steam and the device is called a “steam jet ejector.” Basic ejector components are the steam chest, nozzle, suction, throat, diffuser and they discharge (Fig. 1).

  • An experimental study of an ejector cycle refrigeration

  • How To Choose Ejector Pins For Injection Molding

    The lowly ejector pin for injection mold making just doesn’t get the credit that it deserves. No matter how well the rest of the mold is made, if the ejector pins flash or are the wrong length and contour the plastic part will be rejected. That is why choosing the right pin for the job is important.
