(54) BATTERY OF HORIZONTAL COKE OVENS

The invention relates to the coke industry, namely the batteries of horizontal coke ovens. The closest technical solution is a coke oven battery | including the base with oblique passages, the relative piers with vertical ducts placed on it | forming chambers of coking, and vault. The coke oven is made of special-grade dinas brick, and the roof and base are made of dinas brick of various configurations and sizes. The disadvantages of the known construction are large capital costs for the construction of the battery, insufficient strength, durability of the masonry, complexity and laboriousness of installation. the disadvantages are due to the fact that for the construction of the battery they use a large number of p & various standard sizes, small-piece fire & ampoule resistant material, the assembly of the battery, features of its laying, carried out with the involvement of manual labor in a large volume, and this leads to an increase in the cost and duration of work. The presence of a large number of horizontal and vertical welds reduces the strength and durability, because during operation, due to fluctuations in temperature and mechanical loads, the connection between individual bricks weakens, and individual bricks can fall out, and the masonry, first of all, of the heating walls can be destroyed. The purpose of the invention is to reduce capital costs, increase the strength of the heating walls, increase service life and ease of installation of the battery. This goal is achieved in a coke oven battery, including a base with oblique passages, heating walls placed on it with vertical channels, forming chambers

coking, and the vault, in which the furnace base is made of alternating mono-bottom chambers of coking chambers and blocks with oblique tunnels, the vault is made of alternating monolithic blocks of cambro-coking and blocking of vertical channels of the heating npcTenKOBJ heating wall is made of monolithic blocks and a vertical channel Vgablnen in each of these blocks.

In addition, the surfaces of the bottom blocks, blocks of blocking of the coking chambers and blocks of the heating walls facing the coking chamber are futurised with refractory material, which increases the service life, and for ease of installation, the connecting surfaces of the blocks have trapezoidal projections and grooves.

The proposed implementation of the battery of large-block elements reduces the cost of building bricks. The assembly of a battery consisting of a limited number of elements is simplified and can be carried out industrially by a method with extensive use of mechanization. This leads to a reduction in time and a decrease in the labor intensity of construction.

The location of the slip seams between the elements is chosen such that it does not reduce the strength of the battery. There are no horizontal seams in the heating wall, which provides its strength for strength under the action of flexural loads.

The lining of the surfaces of the blocks, coated with the coking chamber, with a material of increased strength and durability prevents rapid destruction of the base material. The configuration of the docking surfaces by the block provides for axial centering, which creates the convenience of washing.

Fig. 1 shows a schematic of a battery, a section along the axis; Fig. 2 shows a section A-A in Fig. 1; in fig. 3 - section bb in fig. 1, fig. 4 - monolithic block of the heating pier, section.

The battery of horizontal coke ovens contains a base made of alternating monolithic bottom blocks 1, blocks 2 coking chambers and blocks 3 with oblique passages, the arch is made of alternating monolithic blocks 4 blocking the coking chambers and blocks 5 blocking vertical channels 6 of the heating walls.

The heating wall is made of monolithic blocks 7, the vertical channel 6 is made in each of the blocks 7.

The surface of the basement of blocks 1, blocks 4 of the block 7 of blocks 7 of the heating walls of the 1X walls is lined with refractory material on surfaces facing the coking chamber 2,

The coupling surfaces of the blocks 7. have trapezoidal protrusions 8, grooves 9 and channels 10, filled with a sealing material,

To provide chambers for heating the PVR system, in blocks 7 of the heating walls, transshipment windows 11 and windows 12 are provided for the circulation of combustion products. The vault of the battery is covered with a layer of thermal insulation material 13

| The battery is assembled as follows.

The regenerators are placed in parallel rows of blocks 3 with skewed strokes and hearth blocks 1. The position of these blocks and their dimensions determine the width of the coking chambers. The blocks 3 are installed blocks 7 heating walls. Their installation and sealing is facilitated by the presence of tee-like protrusions 8 on these structural elements. In addition, the blocks 7 are mutually centered; when installed, the blocks 5 overlap the vertical channels 6 and the blocks 4 block the coking chambers on top of the blocks 7. This battery design will increase the strength of the heating wall of the coking chambers under the action of disassembling efforts by 3-4 times, reducing the capital construction costs by 10% -30%, reducing the use of manual labor and the duration of the construction of batteries in it by about half.
