ABSTRACT:
A once-through stem generator includes a vertical gas flue having a total given height, a bottom, a lower part having a height equal to less than 70% of the total given height, an upper part, and fossil fuel burners disposed on the lower part. The lower and upper parts are formed of gas-tight tube walls with tubes. The tubes of the lower part rise obliquely, while the tubes of the upper part are vertical. The lower part has a lower end limited by the bottom, and the upper part has an upper end limited a partition of the vertical gas flue, by a cross-sectional restriction of the tube walls, or by a lower edge of a heating surface within the vertical gas flue.
