Definitions

  • the invention relates to a method for a cyclical operation of coke oven chambers of the “Heat Recovery” type which form part of coke oven banks, said operation particularly relating to the cyclic phases of “charging-coking-pushing” and with the procedures of pushing determining the cycle being so arranged that the production of hot coking gases utilized according to the “Heat Recovery” process for the production of steam and energy is evenly distributed over the temporal mean of the entire coking process, thus substantially improving the production of steam and energy, and in particular of electrical energy downstream of the coking process.
  • the coking gas evolving on carbonization can be utilized in different ways.
  • the coking gas is captured and utilized in order to recover and exploit the valuable substances contained therein, for example aromatic hydrocarbons, hydrogen, ammonia, and methane.
  • the coking gas is utilized to burn it and thereby to generate heat which is exploited for the process of coal carbonization.
  • These design types in turn, it is possible to pass the coking gas after combustion and exploitation of the evolving thermal energy without any further use into the environment.
  • These design types are called coke ovens of the “Non-Recovery” type.
  • Other design types in turn utilize the waste heat to recover steam thereof. This can be utilized, for example, to generate electrical energy.
  • These design types are called coke ovens of the “Heat Recovery” type.
  • coke ovens The arrangement of coke ovens is basically so taken that between 6 and 34 coke ovens are grouped together to be linked to each other in a major unit, which is also called a coke oven bank. In this manner, the production of coke can be substantially homogenized. Since the coke oven chambers have to be charged to allow for production, the charging procedure can by noticeably simplified and automated by forming groups of several coke oven chambers.
  • coal carbonization is accomplished in a “charging-coking-pushing” phase cycle. While the coking cycle still lingers on with some coke oven chambers, other chambers can be charged or pushed. In this manner, a constant output of combustion gas is also achieved.
  • Coke pushing is accompanied outside the coke oven chamber on the opposite side of a coke oven chamber by the filling of a coke quenching car.
  • the method applied is that a combination of several coke ovens of the “Non-Recovery” type or “Heat Recovery” type is called “oven bank”. Conversely, a combination of conventional coke ovens is called “oven battery”.
  • WO 2006/128612 A1 describes a method for carbonization of coal in a coke oven with combustion of coking gas, said coking gas initially streaming into a gas space above the coke cake where it is partly burnt with an understoichiometrical volume of supplied combustion air.
  • This process is called primary combustion and it utilizes so-called primary combustion air for combustion.
  • Partly burnt coking gas is then passed via so-called “downcomer” channels into a secondary heating space where it is completely burnt with another quantity of supplied combustion air.
  • secondary combustion and it utilizes so-called secondary combustion air for combustion. Thereby the lower section of the coke cake is also heated, thus improving the coke quality.
  • the invention lays claim to a device and a method for homogenization of the supply of primary combustion air into the gas space above the coke cake, so that heat distribution in the upper section of the coke cake is homogenized and a better coke product is thus obtained.
  • the invention is equally exploitable for a coke oven of the “Non-Recovery” or “Heat Recovery” type.
  • U.S. Pat. No. 5,968,320 A describes a coke oven of the “Heat-Recovery” type which discharges the raw coking gas from the coke oven and burns it in a boiler system in order to generate heat and electric power.
  • the raw coking gas is sprayed for cleaning with a flushing liquor and burnt in a burner where it is exploited to generate steam and mechanical energy. This can be utilized, in turn, to generate electrical energy.
  • a negative pressure furnished by installing a suction blower downstream of the combustion chamber is generated in the combustion chamber.
  • a control of the quantity of combustion gas is only feasible in a simple manner via a change in cycle times.
  • an intermediate arrangement of tanks or accumulator facilities for hot combustion gas is not desired.
  • a change in cycle times can only be accomplished via a precisely controlled temporal sequence of the controlled approach to the coke oven chambers. From conventional horizontal-type coking chamber technique, the sequence of such a controlled approach is known under the name “pushing schedule”. It is also determined by the duration of the coal charging procedure and by the maximum travel speed of the oven service machines.
  • a precisely planned set-up of a pushing schedule allows for a simple homogenization of the stream of hot combustion gas.
  • Combustion gas is understood to cover a gas, too, that is completely burnt and streams out from a coke oven chamber. But it may also be a partly burnt coking gas if it is burnt in the succeeding auxiliary facilities or in the boilers.
  • the invention solves this task by providing a device that combines the coke oven chambers of the “Heat Recovery” type in a distinct number to coke oven banks and by providing a method that controllably approaches these coke oven chambers in an exactly determined sequence for coke pushing. Since the so-called “charging-coking-pushing” cycle terminates with the pushing cycle, the entire cycle for the individual coke oven chambers is controlled with the end of this pushing cycle. The temporal approach to the individual coke oven chambers is so accomplished that the temporal duration of the charging and pushing procedures performed without production of hot combustion gas is distributed over all coke oven banks and over all coke oven chambers. Hot combustion gas is then continually produced during the coking cycle. Owing to the exactly controlled temporal distribution of the cycles over all coke oven banks and coke oven chambers, the production of hot waste gas is so homogenized that control facilities like gas accumulator, tube switches or intermediate tanks are no longer required.
  • the coke oven chambers are so configured that they are steadily linked in a spatial integration to form coke oven banks.
  • the spatial integration can be accomplished in an even or odd number.
  • a linkage is considered to be a constructive encirclement of coke oven chambers. It can be of any arbitrary configuration. It can be implemented by brickwork or jacketing around. But it may also be implemented by an intermediate wall.
  • the term “pushing cycle” is deemed to mean both parts of the coking cycle “pushing and charging”. Coal is preferably not preheated and directly charged into the oven pre-warmed by the preceding coking cycle.
  • the charging machine is always combined with a quenching car that can controllably approach the opening to be charged so as to allow for a pushing procedure.
  • the pushing procedure is preferably so accomplished that the charging procedure is performed by proceeding from the frontal front-end side coke oven chamber wall while the pushing procedure is performed by proceeding from the frontal rear-end side coke oven chamber wall.
  • two coke oven banks each are connected in pairs to one boiler.
  • the coke oven is comprised of ten coke oven banks, then the entire unit is comprised of five boilers. These are utilized to generate steam and energy.
  • the boilers are supplied with hot coking gas coming from the coke oven banks. This is advantageously accomplished through a piping that is linked via a collecting device to the individual coke oven chambers.
  • a controlled approach to the individual coke oven chambers for charging is so accomplished that only one coke oven chamber of the individual coke oven bank is initially approached. For example, this is the first coke oven chamber of a coke oven bank.
  • a coke oven chamber of the next but one third coke oven bank is approached after approaching the first coke oven chamber of the first coke oven bank.
  • Another boiler (boiler number 2 ) is linked to the third coke oven bank, thus avoiding an additional maximal volume flow which would lead to an uneven supply of combustion gas into the boilers.
  • This proceeding is applied on all coke oven chambers of the first coke oven chambers each of the next but one coke oven bank each until the first coke oven chamber of the last but one coke oven bank has been pushed and charged. These procedures represent a first pushing cycle.
  • a controlled approach to the individual coke oven chambers also depends on the temperature gradient in the coke oven bank.
  • the coal charging procedure initially entails a temperature drop in the oven, it is generally of some importance for a constant heat budget of an individual oven y that the adjacent ovens y+1 and y ⁇ 1 are not served immediately, i.e. a few hours, after oven y, if possible. This would entail a temperature drop in an entire oven bank section. It is purposive to choose the charging cycle in such a manner that the adjacent ovens y+1 and y ⁇ 1 are served only after at least 24 hours.
  • Claim is particularly laid to a method for cyclical operation of a sequence of an even or odd number of coke oven banks of the “Heat Recovery” type comprised of an even or odd number of coke oven chambers, wherein
  • the method is so devised that relative to the coke oven banks exactly half the number of boiler systems is existing so that these are linked in pairs to the boilers.
  • This method is characterized by the term “pushing schedule 2*x/1*(x+1)/2”.
  • X represents the number of coke oven chambers per coke oven bank.
  • the pushing schedule may be varied. This is feasible in the extent in which a substantial homogenization of the combustion gas stream is effected. For example, a pushing schedule “2*x/1*x/1” is also feasible. It would mean that
  • the method is so devised that relative to the coke oven banks exactly half the number of boiler systems is existing so that these are linked in pairs to the boilers.
  • a simpler mode of operation consists in approaching the first coke oven chamber of the next coke oven bank each.
  • the corresponding pushing schedule is then called 1*x /2′′′. This requires substantially less expenditure on movements of the charging machine. The homogenization of the combustion gas stream, however, will then be less. Likewise, adjacent coke oven chambers are more strongly charged with heat.
  • the pushing schedule means that
  • the method is so devised that relative to the coke oven banks exactly half the number of boiler systems is existing so that these are linked in pairs to the boilers.
  • the boilers are utilized to generate steam in order to drive a turbine.
  • This propellant energy can be exploited arbitrarily.
  • the propellant energy is preferably exploited to generate electrical energy.
  • the boiler system is equipped with appropriate devices. These devices include heater facilities, boilers, turbines, steam separators, shafts and generators. Supplementary facilities may also be provided, if the mechanical energy is to be utilized in a different manner.
  • the waste gases are preferably fed into a device for gas cleaning to minimize environmental pollution possibly caused by the coke making process.
  • sulfuric compounds are removed from the waste gas during the gas cleaning process so that the gas cleaning facility preferably is a desulphurization facility.
  • this may be a gas scrubbing unit applying a gas-absorbing solvent.
  • the coal is loaded by a coal charging car from the frontal side into the coke oven chamber.
  • the door is closed.
  • the coke is removed from the coke oven chamber.
  • the coking process basically takes approx. 20 to 90 hours.
  • pushing is effected towards the other side of the coke oven chamber.
  • Coke oven chamber doors easy and quickly to handle are located on either side of the coke oven chamber.
  • hot coke Upon charging, hot coke is pushed into a coke quenching car. To execute the invention, it can approach the single coke oven chambers individually.
  • the coke quenching car may be provided with a cooling facility. But to be able to quickly execute the discharging processes, it is preferably equipped with a facility for protection from high temperatures. After pushing and discharging of the hot coke, it is preferably passed with the quenching car into a completely cooling facility. For example, this is a coke quenching tower. But it may also be, for example, a coke dry quenching facility.
  • the coke oven chambers are combined in even or odd number to coke oven banks.
  • the coke oven bank is preferably comprised of 6 to 34 coke oven chambers.
  • the coke oven bank is exactly comprised of 10 to 18 coke oven chambers.
  • the coke oven bank is comprised of 14 coke oven chambers.
  • To supply the boilers or boiler facilities with hot waste gas they are preferably linked to pairs of coke oven banks. This is accomplished via pipelines and appropriate collecting facilities. In theory, however, it is also conceivable to link the boilers or boiler facilities to three coke oven banks each, but in this case the distribution of hot gas is much more difficult.
  • one boiler is linked to two coke oven banks. However, it is also conceivable to link one boiler to one, three or more coke oven banks.
  • the inventive method provides the benefit of a uniform supply of hot combustion gas to boilers or boiler facilities of coke oven systems. Consequently, the generation of steam by the boiler systems is substantially homogenized. As a result hereof, the generation of electrical energy is much easier. The output of contaminants and pollutants from a coke oven system is thus reduced noticeably. If electrical power is generated by the inventive process, then the generation of electrical power, too, is homogenized and optimized.
