ABSTRACT:
A pipe assembly-heat exchanger-steam drum unit, which comprises a pipe assembly heat exchanger for a heat exchange between media of relatively high pressure differentials and a steam drum with a liquid chamber and a steam chamber while the medium passing through the pipes of the pipe assembly-heat exchanger has a high entering temperature, and a pipe bottom located on the inflow side of the hot medium is thin. In the pipe assembly heat exchanger there is furthermore provided a device for relieving the thin pipe bottom. In the pipe assembly-heat exchanger there is also provided a device which is so designed that the cold medium entering the pipe assembly-heat exchanger is conveyed to the thin pipe bottom. The pipes of the pipe assembly-heat exchanger are as an assembly of pipes transversely and centrally passed through the steam drum while the pipe assembly-heat exchanger and the steam drum form a unit with each other. The pipes are at the inflow side of the hot medium by means of the thin pipe bottom connected to the mantle of the pipe assembly-heat exchanger while the pipes in the discharge side of the medium passing through the pipes are through a thin pipe bottom connected to the upper side of the mantle of the steam drum.
