SU30667A1 - Combined Regenerative Coke Furnace - Google Patents

Description

The main structural elements of modern coke ovens are the heating device of the chambers and the device utilizing the heat of waste combustion products. Depending on the principle of heating the chambers, the heating passages of the heating wall of the furnaces are combined with each other in the form of doubles, arranged along and across, chambers for mutual maintenance, then the heating springs of two adjacent heating walls connected to each other, The furnaces located in the roof or, finally, the chambers are heated by systems of heating channels separated in two, connected at the top by a common bypass collecting horizontal channel.

A device that uses heat from the combustion waste products may be either common to the whole battery, or. separate for each chamber, or, finally, for each vertical channel, and the combination with the heating wall of the chambers can be designed by directly connecting a number of bypass channels located under the chambers under the bottom of the chambers or under the heating wall. The latter option, as is known, is not desirable (141)

It is solid, since, apart from weakening the structural strength of the installation, it makes it very difficult to evenly distribute air and gas flows in the heating passages.

The newest designs of coke ovens of the combined type, unlike furnaces operating on their own gas, require for structural design, besides the presence of air regenerators, also gas and combinations of the latter, i.e. two pairs of regenerators with heating walls of chambers operating according to the principles indicated above, which is the most difficult problem to solve when designing furnaces.

Combined coke ovens, currently under construction in Western Europe and America, still do not sufficiently solve the problem of a regenerative device for furnaces of this type. The newest structures, however, with paired, mutually serving channels, in order to avoid the above disadvantages, already connect the regenerative device with the heating walls through the bypass bottom channels, which, in addition to weakening the structural strength, cause uneven distribution of air-gas flows.

The proposed coke flax furnace, despite the direct connection of the heating passages of the heating pier of the chambers with air "gas regenerators, is aimed at eliminating the above disadvantages, which is supposed to be achieved by arranging regenerators of one or another thickness of the supporting wall, Thus, the structural strength of the furnace with the uniform distribution of gas and air flow in the heating passages, as well as full If there are no cracks, there is no gas bypass of air and air, since the walls separating these streams can be developed in any thickness and, besides, their contact surface is insignificant.

In the proposed furnace (Figs. 1. and 2), the principle of heating chambers is carried out by paired mutually serving heating channels, the even system for which two adjacent heating walls are directly connected to two gas floors d and air 1 regenerators located under the furnace hearth. and divided in half by a transverse wall. The odd system b is also associated with transverse walls split in half and gas and air regenerators e and 1 arranged in two floors, working either upward or downward, depending on the inversion. In addition, the proposed furnace provides for the possibility of positioning air and gas regenerators, depending on the inversion, either in the upper or in the lower floors, for example, e and d, then ej and ufi. Finally, the specified regenerative device can, depending on the choice of the principle of heating the chambers, be combined with paired mutually serving heating passages located both along the heating wall and across the chambers, as well as with the heating passages of two adjacent heating walls connected with each other. other bypass channels located in the roof of the furnace chambers, etc.
