Abstract
The invention relates to a system for reducing radial leaks in an air heater for thermal equipment, the heater being of the type including a rotor fitted with a plurality of heater elements supported by diaphragms, a stator constituted by a leakproof metal case, and radial sealing means including hinged sector plates positioned over the heater elements together with radial gaskets provided on the diaphragms. The system has a mechanical mechanism for acting on the functional clearance that exists between each sector plate and the radial gaskets, wherein said mechanical mechanism is controlled by a regulation mechanism connected to information gathering mechanism for providing information about the operating rate of the thermal equipment, wherein the regulation mechanism continuously imposes a position for each plate relative to the radial gaskets, wherein the regulation mechanism determines the relative position based on a relationship between deformation of the sector plates and an operating rate of the thermal equipment as conveyed by the information gathering mechanism.
