The analysis the state of coke batteries was carried out, with the help of which the main types of masonry wear the coke oven heating walls were established. The dynamics and nature of the damage suggest that for batteries with a long service life an individual approach is needed, both in the choice of the technological mode and in the selection of the raw material base coking, taking into account the pressure magnitude of coking blend. Since, in the process of coking coal blends, one the external manifestations of this process is a development of pressure expansion to the walls of coke oven chambers, when calculating the strength of coke ovens, the pressure of 7 kPa is taken as the critical pressure expansion. Exceeding this value leads to an increase in amperage and drilling of furnaces during the coke delivery of, premature wear of the refractory masonry, which requires more frequent repairs, and in extreme cases, deformation the walls of coking chambers. Therefore, coal blend, it is necessary to compile, taking into account not only the production of coke with the necessary mechanical strength, but also ensuring a bursting pressure not exceeding the standard value. To do this, in a laboratory setting to determine the pressure expansion, it is necessary to classify the incoming coal concentrates according to the indicator of pressure expansion, in order to compile blends with a safe value of pressure expansion.

The existing experience and results of previous studies for the production of emulsions from resinous waste and by-products of coke production has been analyzed. A necessary condition for the creation of stable emulsion is the presence in its composition of three main components: diluent oil, emulsifiers and a neutralizing agent. In order to determine the suitability of waste and by-products of production of PJSC "YUZHKOKS" as components of water-oil emulsions, the physicochemical characteristics of acid tar of ammonia capture, neutralized acid tar of rectification of crude benzene, resins and oils of biochemical plant, non-boiling residues of monoethanolamine desulfurization of coke oven gas, alkaline water, storage waste and coal tar has been studied. The ability of these materials to mix with each other has been also studied. As a result of research, it has been found that the presents of coal tar in the composition of the diluent oil leads to the formation of more stable over time emulsions with low viscosity. The amount of coal tar in diluent oils should be 50-70 %. Non-boiling residues of monoethanolamine purification of coke oven gas from hydrogen sulfide proved to be a better neutralizing agent than alkaline water, in particular, for the reason that in some cases their use allowed to obtain homogeneous mixtures without delamination and separation of the aqueous layer by mixing emulsion components. It has been shown that when emulsions preparing it is important to follow the order of mixing the components. Based on the obtained data, formulations have been developed and the conditions for obtaining stable emulsions has been determined. Recommendations for obtaining emulsions for the purpose of their qualified use by feeding to the coal blend and improving the operation of the existing plant for waste and by-products utilization at the enterprise has been formulated.

Addition Amount

In this paper, a research on adding dusts of blast furnace (DBF) which contains iron and carbon to the coal blend was carried out on 5 Kg coke oven. The influences of addition amount (0.25%~1.25%) and size distribution (0~2.5 mm) for DBF on the quality of the coke were investigated. The results showed that the influence on the quality of the coke was little when amount of DBF was less than 0.25% and particle size was from 0.5 mm to 1 mm, but the quality of the coke decreased obviously when addition amount was more than 0.25% and the size was larger than 1 mm.
