Abstract
The synthesis gas cooler is provided with a movable platform in the space between the inner and outer flue. The platform may be constructed in segments with separate cable and winch means provided for raising and lowering of the platform segments via suspension structures. The suspension structures may also be secured in a raised position by bars which pass through fittings at the upper end of the suspension structures and which are supported in a partition above the movable platform.
Claims11
A heat exchanger comprising
- a pair of coaxial vertical flues disposed in spaced relation to define an annular space therebetween with the inner flue defining a central chamber, each said flue including wall tubes for passage of a medium therethrough;
- at least one gas lead-through communicating with said central chamber at one end of the heat exchanger;
- at least one gas lead-through communicating with said annular space at said one end of the heat exchanger;
- at least one orifice in said inner flue communicating said central chamber with said annular space at an opposite end of the heat exchanger;
- an annular platform disposed within said space coaxial of said flues;
- means for moving said platform vertically between said flues;
- and
- at least one manhole between said gas leadthroughs for providing access to said space.

A heat exchanger comprising
- a pressure vessel;
- a pair of concentric vertical flues disposed within said vessel in spaced relation to define an annular space therebetween with the inner flue defining a central chamber;
- at least one spigot in said vessel communicating with said central chamber at one end of said vessel;
- at least one spigot in said vessel communicating with said space at said end of said vessel;
- an annular platform disposed within said space concentrically of said flues;
