The invention relates to the production of carbon products and can be used for calcining products in multi-chamber ring furnaces.

The purpose of the invention is to increase the yield of the product by improving the quality of heat treatment of carbon products to reduce energy costs for transporting flue gases.

Figure 1 presents the chamber furnace, a vertical section; figure 2 - section aa in Fig, 1; Fig.3 section bb in Fig.2.

A chamber kiln for burning carbon products contains working chambers 1. In the separating section 2 of the chambers, vertical chambers 3 are made between chambers to sequentially transfer flue gases from one chamber to another.

Each chamber consists of a lined body 4 with a bottom 5, a removable vault 6 and cassettes 7 mounted directly on the bottom of the furnace.

In the side walls of the cassettes of the chambers there are horizontal channels 8 for the passage of flue gases connected to vertical channels and arranged in rows along the height of the furnace. The burner 9 is installed above the channels 3. Carbon products 10 and backfill 11 are located between the walls 12 of the cassettes. In the underspace space 13 of the cassettes, there are holes 14 for outputting the effluent to the inter-chamber channels. The holes 15 with the pipe 16 connects the channels 3 with the exhauster 17.

Chamber kiln for burning carbon products works as follows.

The cassettes 7 of the chamber 1 are loaded with carbon products 10 and backfilling 11. Chamber 1 is closed with a removable vault 6, after which the burners 9 are ignited. The flue gases produced during the combustion of fuel from the vertical (chamber) channel

enter the horizontal channels 8, the machine 12 cassettes 7 of the furnace chamber 1, and then into the subsequent vertical inter-chamber channel, etc.

The heat of flue gases is transferred to the carbon products 10 through the walls 12 of the cassettes 7 and backfill 11. When heated, volatiles are released from the products 10, which enter the underflow space 13 of the furnace chambers 1, and then through the opening 14 enter the vertical inter-chamber channel 3 mixed with flue gas.

Flue gases with volatile gases pass through a number of furnace chambers. Exhausted by a smoke exhauster.

17 through the hole 15 and the pipe 16.

In the proposed design of a chamber furnace for burning carbon products by connecting inter-chamber vertical channels along the entire height by horizontal channels in the walls of the cassettes, the yield of the product increases by 1.2 times. The energy costs of transporting flue gases through the chambers are reduced by 10% while reducing the hydraulic resistance to the passage of gases by 30%, and the design of the furnace is simplified.
