But they have the disadvantage that the output of hot combustion gases must be almost completely constant by a measure of time in order to ensure a uniform supply of combustion gases to the boiler which produces steam from the waste quantities of coalification

Embodiment Construction

[0050] figure 1 Shows the crude gas amount of coking gas formed above the coke cake during coking and mainly composed of hydrogen, carbon monoxide, methane, and water vapor components. The amount of crude gas is determined in volume units of standard cubic meters per hour throughout the coking cycle. The amount of raw gas is directly proportional to the amount of fully burned coking gas, which flows into the coke oven chamber as combustion gas.

[0051] Figure 2 shows the cycle plan for the "charging-coking-pushing" cycle including the 28 / 15 / 2" coke pushing plan. Each small rectangular block represents a coke oven chamber arranged as a coke oven bank. Each coke The oven groups are numbered in the first column of the illustration and are vertically delimited by columns (Balken). These columns are numbered from 1 to 10. Each coke oven battery consists of 14 coke oven chambers; Numbered in the second column with a number from 1 to 140. The times of the individual cycles are ind...

Abstract

The invention relates to a method for cyclically operating a coke oven device, wherein said device comprises an even number of coke oven banks, each in turn comprising an even number of coke oven chambers. Boiler devices are connected downstream of the coke oven banks, driving turbines using the hot exhaust gases from the coke oven banks. Energy is obtained in this manner. The coke oven chambers are cleared and filled in a precisely defined cycle, so that the production of hot exhaust gas can be homogenized over time.

Description

technical field [0001] The invention relates to a method for the cyclical operation of a "heat recovery" type coke oven chamber which is part of a battery of coke ovens, wherein the operation relates in particular to the cycle stages "charging-coking-pushing" , while the cycle-determined coking process is timed in such a way that the production of hot coking gas used in the method of "heat recovery" for the production of steam and energy is evenly distributed over the time measure of the entire coking process, And thus the production of steam and energy downstream of the coking process is significantly improved, and in particular the production of electrical energy is significantly improved. Background technique [0002] In the coking of coal, the coking gas released during coking can be utilized in various ways. Some configuration types collect and utilize the coker gas in order to capture and utilize the valuable species contained therein such as aromatic hydrocarbons, hy...
