Gas generator

摘要

A gas generator is provided for the production of gas from fuel and steam under conditions of high pressure and temperature. The requisite temperature is preferably provided by a nuclear reactor. The gas generator includes a cylinder wth a hollow interior. Extending transversely through the hollow interior of the cylinder is a container. Tubular heat exchangers are vertically arranged over the length, width and height of the cylinder in such a manner that the density of heating surfaces decreases along the length of the container.
