Turbo cylinder drain
Thread Content
At the exhaust end of the condensing turbine, there is a pipeline for draining the condensate from within the cylinder; how is this condensate removed? Some plants use VF-20 (vacuum flash tanks) connected to the cylinder drain lines, from which the fluid is then sent to the large surface condenser. Are there any other methods for emission control? What do the other sister factories do?
What we are saying to you is the same: this allows the condensate to be recovered, and it also helps maintain the vacuum level of the shaft seal.
What was said above is wrong! How does one maintain the vacuum level of the shaft seal? It should be to maintain the vacuum level of the exhaust-side units. Are there any other methods?
If the turbine discharges steam at the top, a device similar to VF20 is generally installed in this case; if it discharges steam at the bottom, no additional pipes are needed to drain the condensate during normal operation.
The lower exhaust system also has a liquid discharge pipe for direct suction treatment
Our factory exhausts steam upward, but it doesn’t have a VF20. Do you know how it manages to exhaust the steam? I don’t know; it’s connected to the hot water well that leads to the surface condenser anyway. [Last edited by *aoye613 on 2009-4-20 20:38]
