Description

The proposed semi-coking furnace is of the type of furnaces operating on the principle of distilling crushed fuel in a thin layer, and is intended for coking non-caking coal;

In FIG. 1, h: brazh; -1et cross vertical section of the proposed furnace; fkg 2 something to, forks cf.gredl and a longitudinal vertical section; FIG. -3- DC section in FIG. TO

The proposed furnace consists of an I-unit; a coal mine, divided by its height into a series of chambers equipped with EH: heating surfaces, p. cr :; 1o: -: ennym at an angle of repose 1 ;; 1; ground fuel. The chambers are connected to each other through turnstiles in intermittent order,; -: ak and heating channel: nygrevg surfaces.

Each chamber is equipped with a filter for distilling distillation products.

Chel Binsky coal at 400-550 ° gives 70-90. gas; per ton of coal loaded with a calorific value of 5500-6000 calories and 5.5-6, primary resin.

Coal from the hopper is fed using toothed rolls onto an inclined heating surface set at an angle of angle of repose of the coal. All inclined surfaces In the first six, the process is alcoxed; and late-coking. For a uniform flow of carbon planes, they are divided by low partitions into trays with a width of 25 cm each. The finished coke is discharged onto a metal conveyor, which transfers it to the quenching chamber. Production lines are sucked from each, individual section into separate gas pipelines.

Approximately designed the following dimensions are not available: height 15 m, width 2 m and length of one section 3 m,

length of the inclined plane is 2 m. The heating of the inclined surfaces is produced by the products of gas combustion that is burnt under the lower surfaces, but additional fireboxes are provided under each. With such a heating system, 1 m of the surface can produce from 70-75 kgg / h with a coal thickness of 3 m. The resin will be free of dust due to the slow movement of the coal over the heating surfaces.

A built-in kiln with a capacity of 15 lgg / shg gave results that justified the assumption.

The subject matter of the invention.

1. A semi-coking furnace, characterized in that it consists of a vertical; a flax shaft divided by height into a series of chambers that are located -1 at an angle of repose on the surface i grpeea and connected to each other

alternately with turnstiles.

2. The form of the furnace according to p. 1, characterized in that the heating channels of the inclined heating surfaces of the individual chambers are also connected to each other in an intermittent order.

3. The form of the furnace, according to paragraphs. 1 and 2, characterized in that the heating channels of the individual chambers, in intermittent order, are provided with additional heating points.

4. Furnace, in accordance with clause 1, characterized in that the inclined heating surfaces laid out of thin dinas tiles are provided with cast iron plates H1-1. 1 located on them divided by longitudinal partitions into a number of trays.

5.Pech according to. 1-4, characterized by heme, chambers are provided with separate devices for removal of products of DHTILLATION.
