Description

one

The invention relates to the fuel industry and can be used for the thermal processing of solid fuels, such as shale in a transverse coolant flow.

The known furnace with a transverse flow of heat carrier, comprising a housing, vertical gratings installed in the upper part of the housing and dividing it into chambers for distribution of the heat carrier, semi-coking and collecting the vapor-gas mixture, devices for inlet and outlet of gas and solid material and a gasification chamber located in the lower part enclosures between the vertical grilles and the gas inlet.

The purpose of the invention is to ensure uniform movement of solid material over the cross section of the semi-coking chamber.

To do this, cutouts are made at the bottom of the vertical slats along the edges adjacent to the housing.

FIG. 1 shows a gas generator diagram; in fig. 2 is a section A-A of FIG. one; in fig. 3 is a section BB of FIG. one.

The furnace includes a housing 1, vertical lattices 2 and 3, made respectively of refractory material and heat-resistant steel, installed in the upper part of the housing and dividing it into chambers 4-6, respectively, of the distribution of the semi-coking heat carrier and collecting the gas-vapor mixture, respectively.

The middle part of the lattice end 2 rests on the arch 7. To the upper and lower parts of the body are attached devices for input and output of solid material (not shown) and devices 8 and 9 for gas in and out, respectively.

A gasification chamber 10 is located inside the housing between the vertical lattices 2 and 3 and the gas injection device 8. In the lower part of the vertical grids 2 and 3, along the edges adjacent to the housing 1, there are cutouts 11 and 12.

The furnace works as follows.

The solid material to be processed is loaded from above, passes through the semi-coking chamber 5, gasification and is discharged at the bottom of the gas generator. The presence of the cutouts And and 12 in the grids 2 and 3 leads to the fact that the speeds of movement of the solid material at the edges of the lattices and in the middle part of the chamber 5 of the semi-coking are aligned and, as a result, the processing of the solid material becomes more uniform.

The processing gas through the device 8 enters the gasification chamber 10, passes through the heated layer being processed

the material in the distribution chamber of the coolant, where it is further heated by burning in this chamber combustible gas. Then, as a heat carrier, the gas penetrates in the transverse direction under the force of gravity a layer of material in the semi-coking chamber 5 and through the vapor-gas mixture collection chamber 6 and the device 9 is removed from the gas generator.
