Steam generator with increased safety and service life

摘要

The burner chamber for a lignite-fired steam-raising plant has tubular walls (1). It has a water separator (5), flue chimney walls (2) and inner wall piping (3) of the individual flue gas return suction shafts arranged in series. One or more successively arranged convection superheater steps can be arranged between the flue chimney walls (2) and the inner piping (3) of the return suction shafts (4). The medium temperature in the pipe wall lies below the limit of the pipe wall material.
