Abstract

Zwangdurchlaufdampferzeuger für die Verfeuerung von Trockenbraunkohle ohne Zuhilfenahme von rückgeführtem Rauchgas in dessen Brennkammer, wobei der Zwangdurchlaufdampferzeuger (1) eine Brennkammer (2 und einen an deren oberen Ende anschließenden Rauchgaszug (3) sowie diese umgebende Umfassungswände (4) aufweist, wobei die Umfassungswände (4) aus Rohrwänden (5) gebildet sind, deren Rohre das Arbeitsmedium Wasser/Dampf führen, die Brennkammer (2) wenigstens einen Brenner (6) aufweist und im Rauchgaszug (3) Nachschaltheizflächen (7) angeordnet sind, wobei ein Teil der Umfassungswände (4) im Bereich der Brennkammer (2) durch wenigstens eine Schottenheizfläche (8) abgedeckt ist, deren flächenseitige Größe so bestimmt ist, dass die Wärmeaufnahme der Umfassungswände (4 und infolgedessen deren Temperatur auf einen Wert reduziert wird, der die Ausbildung der Umfassungswände (4) aus modifizierten, warmfesten 2,25-2,5% Chromstählen zulässt, die nach deren schweißtechnischer Verarbeitung keine Wärmenachbehandlung benötigen.
