Abstract (en)
[origin: EP0604390A2] The system feeds a steam generator which can produce steam at a variety of pressures. It has a heating boiler with HP and LP heating surfaces esp. heated by gases from gas turbines. The water is supplied to the boiler by an eg. two-stage feed pump (1) with a single feed pipe (12) and LP (2) and HP (3) output tappings feeding water via pipes (11,10) and control valves to different parts of the boiler. There is a relief output pipe (9) connected to the HP tapping on the pump to release water and prevent bursting of the pump if the outputs to the boiler should be shut off.
