Abstract

A steam generator has a nitrogen removal device for fuel gas and a combustion chamber, which is followed on the fuel-gas side, via a horizontal gas flue and a vertical gas flue, by a nitrogen removal device for the fuel gas. The steam generator has a particularly low space requirement and ensures a reliable removal of nitrogen from the fuel gases of the fossil fuel. For this purpose, the combustion chamber has a number of burners arranged level with the horizontal gas flue. Moreover, the vertical gas flue is designed for substantially vertical flow of the fuel gas from the bottom upward, and the nitrogen removal device for fuel gas is designed for an substantially vertical flow of the fuel gas from the top downward.
