Steam generator fired by fossil fuel

摘要

The vertical combustion chamber of the steam generator has a rectangular cross-section. The combustion chamber walls are formed by gas-tightly welded tubes. They are coupled at the working middle side lower end to trapezoidal walls of a funnel, also of gas-tightly welded tubes. The funnel lower end locates a rectangular outlet aperture. The funnel kinks of both the front and rear walls and of the side walls are at different height levels. Pref. the tubes of the combustion chamber and the funnel are helically coiled.
