Backpressure turbine drainsThe drain lines should be led to a drain channel or an atmospheric drain tank.Condensing turbine drainsThe drains from all spaces which are under vacuum during start-up must be led to the con- denser.It is recommended, however, that the drains are not led direct to the condenser but to a standpipe arranged adjacent to it. At the top the standpipe should be connected to the steam space and at the bottom to the hotwell of the condenser. The hot drains may thus flash out here without endangering the condenser tubes.
