To vacuum deaerators, as gazootsasyvajushchih devices that apply water jet ejectors. Ejector EV-30 includes a nozzle to which is fed a working water; steam and gas mixture flows in the inlet chamber. In the ejector there is a so-called mixing chamber. Gas-vapor mixture condenseries the initial section resulting from the nozzle of the working water, and the remaining pairs condenseries in the mixing chamber and the diffuser. Here is a mixture of water and air, as well as an increase in the total pressure. Water-gas emulsion is drained from the ejector EV-30 in the tank for the working water.
The water-jet ejector EV-30 use
with the cooler flash steam: HNS-2M;
with vacuum deaerators: DV-5, DV-15, DV-25
