Definitions

  • the invention relates to a method for a cyclical operation of coke oven chambers of the type "heat recovery", which are part of Koksofenbänken, the operation in particular the cycle parts "loading - coking - expressions" concerns and wherein the operations of the cycle-determining expressions in time are arranged so that the production of hot coking gases, which are used for the production of steam and energy by the "heat recovery” method, is evenly distributed over the time average of the entire coking process and thus the production of steam and steam downstream of the coking process Energy and especially electrical energy is significantly improved.
  • the coking gas produced during the coking can be used in various ways. Some embodiments trap coking gas and use it to recover and recover the valuable materials contained therein, including, for example, aromatic hydrocarbons, hydrogen, ammonia, and methane. Other embodiments use the coking gas to burn it and thereby generate heat that is used for the process of coking. In these embodiments, there is again the possibility of giving the coking gas after combustion and use of the resulting heat energy without further use in the environment. These types are called non-recovery type coke ovens, while other types use waste heat to generate steam, which can be used as an example to generate electrical energy, and these are known as heat recovery coke ovens ,
  • coke oven bank The arrangement of coke ovens always takes place so that between 6 and 34 coke ovens are combined to be in a larger unit, also called coke oven bank, linked. In this way, the production of coke can be significantly made uniform. Since the coke oven chambers have to be loaded for production, the loading process can be considerably simplified and automated by combining several coke oven chambers. Indeed, coking occurs in the cycle "loading - coking - expressing.” As the coking cycle continues in some coke oven compartments, others may be loaded or squeezed in. This will also result in a more consistent emission of combustion gas. Chamber on the opposite side of the coke oven chamber accompanied by the infestation of a Löschwagens. When naming the oven combinations, the combination of several "non-recovery" or “heat-recovery” type coke ovens is called the "oven bank.” A combination of conventional coke ovens is called the "oven battery”.
  • WO 2006/128612 A1 describes a process for the coking of coal in a coke oven with a combustion of the coking gas, wherein the coking gas first passes into a gas space above the coke cake, where it is partially burned with a substoichiometric amount of supplied combustion air.
  • This process is called primary combustion and uses so-called primary combustion air for combustion.
  • the partially burned coking gas is then passed via so-called "downcomer” channels into a secondary heating space, where it is completely burned with a further amount of supplied combustion air.
  • secondary combustion uses so-called secondary combustion air for combustion. This also heats the lower part of the coke cake and thus improves the coke quality.
  • the invention claims an apparatus and a method for equalizing the supply of primary combustion air in the gas space above the coke cake, so that the heat distribution in the upper part of the coke cake is made uniform and a better Kokspro- product is obtained.
  • the invention is equally usable for a coke oven of the type "non-recovery" or "heat recovery”.
  • US 5968320 A describes a "heat recovery" coke oven which removes the raw coke gas from the coke oven and burns it in a boiler system to generate heat and electricity and burned in a burner where it is used to generate steam and mechanical energy, which in turn can be used to generate electrical energy, to facilitate combustion and to avoid the costly installation of compressors and measuring equipment, in the combustion chamber

  • the systems described use the heat from the coking and the subsequent combustion process in order to gain steam and energy.
  • a control of the amount of combustion gas is possible in a simple manner only by changing the cycle times.
  • the interposition of containers or storage facilities for the hot combustion gas is not desirable for cost reasons.

  • This procedure is carried out for all coke oven chambers of the respective first coke oven chambers of the next but one coke oven bank until the first coke oven chamber of the penultimate coke oven bank is expressed and filled.
  • the control of the individual coke oven chambers also depends on the temperature gradient in the coke oven bank.
