Abstract:
A Conveyor/cooler of hot loose solid materials produced by fluid bed boilers or various industrial processes comprising:one or more discharge channel(s) substantially vertical or at any inclination along which, because of gravity, the hot loose solid material leaves an area wherein the hot loose solid material is generated;a sealed metallic container connected to a downstream end of said one or more discharge channel(s);a conveyor belt disposed within said container and driven by a motor; anda speed changer for changing an advancing belt speed, the speed changer being operatively coupled to an overpressure sensor and responsive to a signal from the overpressure sensor, a material flow rate being provided by a set belt speed for a given thickness of a material layer on the belt,wherein the hot loose solid material from the downstream end of said one or more discharge channel(s) is layered forming a continuous travelling material bed on the conveyor belt,wherein said belt is adapted to absorb heat from the hot loose solid material and deliver heat to air inside the conveyor/cooler,wherein a distance between said downstream end of discharge tube(s), said one or more discharge channel(s), and the belt is set to allow passage of pieces of material having a predetermined largest supposed size, andwherein said one or more discharge channel(s), when full of the hot loose solid material, forms a plug for separation of pressure between said container and said area wherein the hot loose solid material is generated.
