The boiler has a water jacket, a filling shaft (2), which is closed off at the bottom by a grating, a burner (13) for liquid fuels, which is built into the air duct (9') at the rear of the boiler and opens out parallel to the longitudinal axis of the boiler into the horizontal intake chamber (4) against the direction of the draught, which chamber forms with the upwardly widening draught lock (5) the combustion chamber downstream of the filling shaft (2), a rotational secondary combustion zone in the passage of the intake chamber (4) to the draught lock (5) and the upper exhaust-gas tube (8), which tube serves for preheating the fresh air which is fed to the burner (13) and the outer rotation area (20). <IMAGE> |
