A steam creator (1) has coal dust firing (16). It includes a vertical rectangular-section gas chimney (2) with a combustion chamber (3) at the bottom, producing dry slag. The chimney has enclosing walls and a bottom wall (8). These walls are formed from tubular wall heating surfaces with a heat carrier flowing through them. The bottom wall has at least three ash outlet apertures (9). |
