Abstract:
A method is disclosed for mechanical stoking in firing installations, in which fuel (3, 7) is applied using a mechanical stoker (4) to a grate (2), which is disposed in the firing chamber (1), wherein the mechanical stoker is oriented opposite the delivery direction of the grate (2), and a corresponding installation. The method is characterized in that the fuel (3, 7) is introduced directly below the firing chamber ceiling (5), viewed in the delivery direction of the grate (2) before the end of the grate, so that a burnout zone (10), which does not have fresh fuel (3, 7) applied thereto, is created on the grate (2) between the mechanical stoker (4) and the end of the grate (2). The residual carbon content of the ash can thus be decreased and a decrease of the rotational speed of the mechanical stoker can also be achieved.
Abstract:
A thrower wheel of a mechanical stoker is disclosed having multiple blades (7), which are disposed on a base plate (2), and a corresponding mechanical stoker. The thrower wheel is characterized in that the height of the blades (7) increases in the radial direction in at least one area and optionally remains the same in one or more remaining areas, and the height of the blade is less at the inner end of the blade than at the outer end of the blade. As a result thereof - in comparison to the prior art (4) - the wear load of the inner blade upper edge is distributed onto a larger area, so that the wear of the blade upper edge is thus decreased. Because better kinetic energy transfer from the thrower wheel to the fuel also occurs by the reduction of the impacts, the rotational speed of the thrower wheel can be reduced.

Abstract:
In a process for operating an air-cooled mains supply unit for industrial application, temperatures influenced by outer heat sources and by heat sources arranged in the mains supply unit are measured by thermo-elements (11, 12, 13, 14, 15) and reported to a control system. Temperatures measured by at least two thermo-elements (11, 12, 13, 14, 15) arranged at different measurement points are reported to the control system, and the measured temperatures are compared with temperature patterns. The comparison with known temperature patterns makes it possible to sense the totality of the thermal conditions continuously and to derive therefrom ratings for the control system.
