Abstract

This invention relates to metallurgy, in particular to high-temperature fluidized bed apparatus. The purpose of the invention is to increase reliability by reducing emissions of the layer material. The fluidized bed apparatus includes a working chamber, a gas distribution grid installed above the pilot burner 2, a visor 3 with a pull 4. A visor 3, made in the form of a flat sheet, is mounted so that it can move in a vertical plane. Before the machine is kindled, air is supplied through the gas distribution grid, and the visor is installed inside the fluidized bed 7. The fuel burns under the visor, heating up the boiling layer. After the operating temperature has been reached, the main fuel is supplied to the bed, and the pilot burner is turned off. The visor is removed from the fluidized bed volume. 2 h. item f-ly, 2 ill.

The invention relates to metallurgy, specifically to high-temperature fluidized bed apparatus.

The purpose of the invention is to increase reliability by reducing emissions of the layer material.

FIG. 1 shows the device of the device with a movable visor in the form of a gate; in fig. 2 - apparatus device (f with a visor movably connected to the power unit of the working chamber.

I A device with a skull, it contains a gas distribution grid 1, a pilot burner 2, a visor 3 with a weight of 4, made in the form of a flat sheet mounted on a fire burner with a possibility of stirring, in a vertical plane. The guide frame 5 is installed in wall 6 of the working chamber.

The device with a bobbin shim is working ({; in the following way.

After the operating temperature has been reached, the main fuel is supplied to the bed, and the pilot burner is turned off.

The visor is removed from the volume of the fluidized bed and no longer affects the hydrodynamics of the fluidized bed.

The stabilization of the fluidized bed hydrodynamics leads to a decrease in the entrainment of bed material by gas bubbles, an increase in the completeness of combustion of fuel, and reliability of the apparatus.

Claims (3)

 1. A fluidized bed apparatus containing a working chamber, a gas distribution grid, main burners, a pilot burner and a visor with a draft installed above the pilot burner, characterized in that, in order to increase reliability by reducing the selection of the apparatus through the gas 2Q dew material layer, visor installed |) The distribution grill 1 is supplied with air; The air-fuel mixture is fed into it through go-2. The fuel burns under the visor and the resulting hot products of combustion, heated from under the shelf to the bed, heat it up. 25 movable in a vertical plane. 2. The apparatus according to claim 1, characterized in that the visor is hingedly mounted on the wall of the chamber with the possibility of interaction with the rod. 3. The apparatus according to claim 1, characterized in that the visor is made in the form of a gate mounted in a guide frame in the wall of the chamber. After the operating temperature has been reached, the main fuel is supplied to the bed, and the pilot burner is turned off. The visor is removed from the volume of the fluidized bed and no longer affects the hydrodynamics of the fluidized bed. The stabilization of the fluidized bed hydrodynamics leads to a decrease in the entrainment of bed material by gas bubbles, an increase in the completeness of combustion of fuel, and reliability of the apparatus.
