Abstract

In order to improve the performance of the flue gases exhaust from the tight chamber boiler, IABER S.p.A. uses a hooked pressure tube and a venturi tube, mounted inside the scroll. The location of the venturi and pressure tubes within the fan scroll allow pressure detectors not be affected by the intake air flow, caused by the natural draught of the stack, when the boiler is off. Also the venturi tube alone is useful to this purpose; actually, the solution providing for the only presence of the venturi tube allows a higher stability of the pressure signal reaching the pressure switch and assures that the boiler is shut-off in case of abnormal machine operation. <IMAGE>
