Definitions

  • the present invention relates to plants for cleaning flue gases from coke ovens or coke oven batteries, and can be used in the coke industry.
  • flue gases may contain finely dispersed carbon particles, which are also contaminants.
  • the coking method is used, which consists in the processing of natural fuels, mainly coal, by heating it to 950 - 1050 0 C without air.
  • the main products that are obtained during coking are coke and coke oven gas.
  • coke coals are heated to a temperature of ⁇ 350 0 C, coke coal softens, turning into a plastic state.
  • a complex of thermal transformations of coal occurs with the release of so-called primary products having a complex composition, and at a temperature of about 500 0 C, the plastic mass hardens and a solid porous product is formed, which is called semi-coke.
  • the semi-coke loses residual volatile substances and undergoes shrinkage, causing its separation.
  • semicoke completely turns into coke.
  • Part of the primary coking products namely, primary gas and resinous substances, in contact with the red-hot walls and the coke oven vault, as well as with coke, undergo pyrolysis. Gaseous coking products are captured and used as raw materials for the chemical industry.
  • the coking process is carried out in a coke oven or in a coke oven battery, which includes at least one coke oven. Before loading coal into a coke oven, it is prepared, namely, it is crushed and a charge for coking is formed, which has a certain component composition, which ensures the production of conditioned commercial coke, which allows to increase the productivity of coke ovens.
  • the coking process proceeds in layers, and the temperature of the layers gradually increases from the heated (above 1000 0 C) walls of the coke oven to the middle of the load. Accordingly, the composition of the layers (starting from the walls) changes in the following sequence: coke - semi-coke - plastic state - dry charge - raw charge. Coking is considered complete when all layers of coke converge in the middle of the coke oven. Towards the end of coking, as a result of shrinkage, a so-called “coconut cake” is formed, which is divided in the middle part by a seam-gap running parallel to the heating walls of the coking chamber, and each half of the “cake” is divided into more or less large pieces by cracks.
  • the coke obtained in the furnace is removed from it by a coke ejector and enters the quencher, where the hot coke is cooled with water or an inert gas (“wet” or “dry” method).
  • coke ovens are combined into batteries, 37 to 100 coke ovens each, with heating gas supply systems, coal supply systems, raw coke oven gas removal and flue gas exhaust systems common to all furnaces.
  • the coke oven contains a coking chamber, heating walls located on both sides of the coking chamber, regenerators, a flue gas exhaust system, which consists of ducts located on both sides of the coke oven, while the ducts are adjacent to the hog.
  • Loading hatches are provided in the upper part of the coking chamber; from the ends, the coking chamber is closed by removable doors.
  • the length of coking chambers reaches 16 m, height 4 - 7 m, width 0.4 - 0.5 m.
  • Coking chambers are heated by burning in the vertical channels piers of coke, blast furnace or a mixture of various combustible gases.
  • the heating of the coking chambers is important for the coking process of the charge, since the quality of the coke depends on the uniformity of heating along the length and height of the coking chambers, and the combustion conditions and composition of the heating gas determine the amount and composition of flue gases.
  • the coking period of one coal charge depends on the width of the coking chamber, the temperature in the heating walls, the properties of the coal charge and is usually 13 - 18 hours. However, in some cases, the coking period can be increased to be from 18 to 30 hours.
  • the amount of heating gas for heating the coke oven changes and, accordingly, the volume of flue gases leaving the coke oven changes.
  • flue gases are formed that contain nitrogen oxides, carbon oxides and sulfur oxides. Flue gases can also contain fine carbon particles. Quantity and the composition of the flue gas depends on many factors. The main ones are: the temperature level in the heating channels and the conditions for burning heating gas; the tightness of the masonry of the heating walls of the coking chambers and the coke oven heating system, the coefficient of excess air.
  • the optimum hydraulic mode is the mode that provides a small excess pressure (0.1 - 5 Pa) in the upper part of the coke oven, under the inspection hole. This mode is ensured when the thrust in the flues located on both sides of the coke oven is at the level of 200-300 Pa.
  • Such rarefaction is supported by regulators installed in the flues, the best operating range of which is ensured when the vacuum in the hog is 400-500 Pa.
  • the hydraulic mode is constantly changing.
  • the change in the hydraulic regime depends on many factors, in particular, on the loading of coke oven with coke coal, on the tightness of the masonry walls of the coke oven, on the type of fuel used for heating the coke oven, coking period, and ambient temperature conditions. So, for example, when choosing coke oven gas with a calorific value of -4000 kcal / m 3 , one volume of heating gas is required, and when choosing a blast furnace gas with a calorific value of ⁇ 900 kcal / m 3, it is necessary to use a larger volume of heating gas compared to coke oven gas .
  • Violation of the optimum hydraulic mode of the coke oven leads to a deterioration in the uniformity of heating and, as a consequence, to a deterioration in the quality of marketable coke, and also leads to an increase in the cost of marketable coke.
  • a decrease in the rarefaction (draft) leads to a decrease in the productivity of the coke oven, and an increase in the vacuum leads to leaks in the heating system, an increase in the leakage of raw coke and heating gases, worsening of the conditions for burning heating gas, and, as a result, to a sharp increase in the content of pollutants in flue gases. Therefore, maintaining the optimum hydraulic mode of the coke oven at a given level is a necessary condition for its operation.
