Description

METHODS FOR CYCLICALLY OPERATING COKE OVEN BANKS FROM “HEAT RECOVERY” COKE OVEN CHAMBERS}

The present invention relates to a circulating operation method of a "heat recovery" type coke oven chamber constituting a part of a coke oven bank, in particular the operation is related to the circulating process of "charging-coking-transfer" and said The cycle-determining transfer process is adjusted to distribute the hot coking gas production used in accordance with the "heat recovery" process to produce steam and energy evenly above the temporal mean of the entire coking process. The present invention relates to a method for substantially improving the production of electrical energy, in particular in the subsequent process of coking.

When carbonizing coal, the coking gas released during carbonization can be used in different ways. In some types of designs, the collected coking gas is used to recover and utilize valuable materials contained therein, such as aromatic hydrocarbons, hydrogen, ammonia and methane. In another type of design, combustion is carried out with coking gas to generate heat for use in coal carbonization processes. With these types of designs, you can take advantage of the thermal energy that is burned and released, and then export the caulking gas to the environment instead of using it anymore. This type of design is called "Non-Recovery" type coke oven. Another type of design uses waste heat to recover steam. The recovered steam can be used to generate electrical energy, for example. This type of design is called a "heat recovery" type coke oven.

The basic arrangement of a coke oven takes the form of a main apparatus, also called a coke oven bank, connected to each other by grouping 6 to 34 coke ovens. In this way, coke can be produced substantially homogeneously. Coke oven chambers must be introduced for coke production, which can greatly simplify and automate the input process by forming a chamber group consisting of several coke oven chambers. This is because coal carbonization takes place through a "feed-coking-transfer" process cycle. While the coking cycle continues in some coke oven chambers, other chambers may be fed or transferred. In this way, combustion gases may be produced constantly. The coke cooler outside the coke oven chamber opposite the coke oven chamber is filled with coke and transported. According to the method applied when naming the combination form of the oven, the combination of several "non-recovery" type or "heat recovery" type coke ovens is called "oven bank". In this regard, the combined form of existing coke ovens is called "oven battery".

WO 2006/128612 A1 is a method of carbonizing coal by combustion of coking gas in a coke oven, wherein the coking gas is initially introduced into the gas space above the coke cake and partially burned by combustion air supplied below a stoichiometric volume. It describes how. This process is called primary combustion and uses so-called primary combustion air for combustion. The partially combusted coking gas is then sent through a so-called "downcomer" to the secondary heating space for complete combustion by another amount of supply combustion air. This process is called secondary combustion and uses so-called secondary combustion air for combustion. This also heats the bottom of the coke cake, improving the quality of the coke. The claims of the present invention describe an apparatus and method for homogenizing primary combustion air supplied to a gas space above a coke cake to ensure a constant heat distribution at the top of the coke cake to obtain a better coke product. The invention is equally applicable to "non-recovery" or "heat recovery" type coke ovens.

US 5968320 A describes a "heat recovery" type coke oven for generating heat and power, which describes a coke oven for combusting the raw coking gas discharged from the coke oven in a boiler apparatus. The raw coking gas is sprayed with the cleaning liquid for purification and burned in the burner to generate steam and mechanical energy. This steam and mechanical energy can in turn be used to generate electrical energy. In order to facilitate the combustion and reduce the high installation cost of the compressor and measuring device, a suction blower is installed at the rear of the combustion chamber to generate a negative pressure in the combustion chamber. With this apparatus, the non-uniform waste gas supply from the coal carbonization generated in the operation of the coke oven chamber described above is also uniform. However, in the whole period of coal carbonization, homogenization is not perfect.

The devices described above use steam from coal carbonization and subsequent combustion to recover steam and energy. However, these devices have a disadvantage in that the generation of high temperature combustion gas above the average over time should be almost completely constant in order to uniformly supply the combustion gas to the boiler that generates steam from the heat released during coal carbonization. These boilers should be supplied with the most uniform amount of flue gas possible for optimum operation of turbines and rear-end equipment.

Throughout the coking cycle, the combustion gases produced from one coke oven chamber are not constant. It is known that as the initial 20% of the coking cycle elapses, the maximum amount of source gas is released and the coal carbonization process is greatly reduced. A typical amount of hot combustion gas measured through one coking cycle time of a coke oven chamber is illustrated in FIG. 1. If all the coke oven chambers in a bank are continuously supplied, ie transported and put in, at the end, the boiler located at the rear end is overloaded with this high temperature flue gas overload in a short time to ensure optimal operation. It will no longer work in scope. For this reason, it is practically important to specify a controlled approach to the oven in such a way that only one oven per boiler is provided throughout the entire period.

Control of the amount of combustion gas is only possible in a simple way of changing the cycle time. In view of cost, it is not advisable to arrange tank or vessel installations for hot combustion gases in the middle. On the other hand, the change in cycle time can only be achieved by precisely controlling the temporal order of the controlled approach to the coke oven chamber. From the conventional horizontal caulking chamber technology this controlled approach sequence is known under the name "transfer plan". It is also determined by the duration of the coal input process and the maximum running speed of the oven-operated equipment. By precisely and deliberately drawing up the transfer plan, it is possible to simply and uniformize the input of hot combustion gases.

Accordingly, an object of the present invention is to provide a simple process and method that can control the amount of combustion gas by changing the cycle time or transfer plan. Combustion gases are understood to include gases that are completely combusted and exit from the coke oven chamber. However, the combustion gas may be a partially burned coking gas when it is burned in a subsequent auxiliary plant or boiler.

The present invention for solving the above problems provides a device in which a predetermined number of "heat recovery" type coke oven chambers are included in a coke oven bank and a method for controllably accessing these coke oven chambers in a precisely determined order for coke transfer. do. The final stage of the so-called "feed-coking-transfer" cycle is the transfer cycle, so that the overall cycle of each coke oven chamber is controlled by the end of the transfer cycle. The temporal approach to each coke oven chamber is achieved by ensuring that the duration of the dosing and conveying process is distributed across all coke oven banks and all coke oven chambers without producing hot combustion gases. Thereafter, hot combustion gases are continuously produced during the coking cycle. Accurately controlled cycle time distribution for all coke oven banks and coke oven chambers results in a constant hot gas production, so that control equipment such as gas containers, tube switches or intermediate tanks are no longer needed.

To operate the apparatus of the present invention, the coke oven chambers are configured to be constantly connected in a spatially integrated structure to form a coke oven bank. The spatial integration can be achieved even or odd. The connection is understood as the constructive encirclement of the coke oven chamber. The connection structure may have an arbitrary arrangement. The connection can be effected by stacking or enclosing the wall. The connection may be effected by an intermediate wall. The term "feed cycle" is considered to mean "convey and feed", two constituent processes of the coking cycle. Coal is preferably not directly preheated but directly charged into an oven which has been pre-warmed by a preceding coking cycle.

It is important that all coke oven chambers have controllable access to one feeder and one feeder so that the feed and transfer process can be carried out by a single device. Basically, the feeder is used in conjunction with a refrigeration vehicle which has controllable access to the opening to be fed at all times to enable the transfer process. The conveying process is preferably carried out by carrying out the feeding process from the coke oven chamber wall of the front face, whereas the conveying process is carried out by running from the coke oven chamber wall of the front face. In this way, each cycle can be automated and fast in time.

In order to operate the device of the invention, two coke oven banks are preferably connected in pairs to one boiler. For example, if a coke oven contains ten banks of coke ovens, the entire apparatus includes five boilers. The boiler is used to generate steam and energy. The boiler is supplied with hot coking gas from the coke oven bank. This supply is advantageously made via piping which is connected to the respective coke oven chamber via a collecting device.

Controlled access to each coke oven chamber for dosing is achieved by allowing initial access to only one coke oven chamber of each coke oven bank. For example, the single coke oven chamber is the first coke oven chamber of the coke oven bank. In order to distribute the dosing process as evenly as possible throughout the entire period, the first coke oven chamber of the first coke oven bank is approached and then the coke oven chamber of the third coke oven bank. This is advantageous because another boiler (boiler number 2) is connected to the third coke oven bank, which avoids the introduction of an additional maximum volume which makes the supply of the combustion gases entering the boiler uneven. This treatment is applied to all coke oven chambers of each of the first coke oven chambers of each of the following coke oven banks until the transfer and dosing of the first coke oven chamber of the last to the second coke oven banks is complete. These processes are called first transfer cycles.

This is followed by different transfer cycles for feeding and transferring other coke oven chambers. These cycles will then be applied to each of the next coke oven chambers of each of the next coke oven banks. In this manner, the second coke oven chamber of each of the second and next coke oven chambers is controllably accessible until the access of the second coke oven chamber of the last coke oven bank is complete. In the next transfer cycle, subsequent coke oven banks are transferred and fed in this order. For example, these coke oven banks are the third coke oven chambers of the first and then coke oven bank (s).

The controlled access to each coke oven chamber also depends on the temperature gradient in the coke oven bank. Since the initial temperature of the coal is accompanied by a temperature drop in the oven, adjacent ovens y + 1 and y-1 are not provided as soon as possible after oven y , i.e. after several hours, for a constant heat budget of each oven y . It is generally important. This will entail a temperature drop across the entire oven bank section. It is meaningful to select the dosing cycle in such a way that adjacent ovens y + 1 and y-1 are provided after at least 24 hours.

When all coke oven chamber transfer and addition except the last coke oven chamber have been completed, the transfer and dosing of the last coke oven chamber of each of the first and next coke oven banks takes place in the last cycle. In this way, very uniformly produced waste heat can be sent to the boiler plant over time for all coking cycles so that the waste heat can be supplied evenly to the boiler.

In particular, in the claims, there is provided a method for circulating an even or odd series of "heat recovery" type coke oven banks comprising even or odd coke oven chambers.

The coke oven bank 1 itself consists of at least four series of "heat recovery" type coke oven chambers,

The coke oven bank is connected to a boiler device that generates steam using heat of hot waste gas from the coke oven bank,

The coke oven chamber is transported and fed in the opposite direction of the coke oven chamber by the coke feeder from the front in the precisely determined time interval range, and immediately after the transfer of the respective coke oven chambers and the coking cycle is resumed,

In the first transfer cycle, the first coke oven chamber of the first coke oven bank is transferred and introduced first, and if the number of coke oven chambers per coke oven bank is an even number then the first coke oven chamber of the coke oven bank. Is continuously fed and fed until the transfer and dosing of the first coke oven chamber of the last to second coke oven bank is completed,

In a subsequent transfer cycle, the next coke oven chamber of the next coke oven bank is first transferred and fed in sequence, and then the same coke oven chamber in the sequence of the next coke oven bank is the same coke oven chamber in the sequence of the last coke oven bank. Is transferred and input until the transfer and input of

In a subsequent transfer cycle, the next coke oven chamber in the order of the first coke oven bank is transferred and introduced, and then the same coke oven chamber in the sequence of the next coke oven bank is the same coke in the order of the last coke oven bank. Transferred and fed until the transfer and loading of the oven chamber is completed,

In the final transfer cycle, after the coke oven chamber last in the order of the first coke oven bank has been transferred and fed in, then each of the last coke oven chambers in the next coke oven bank is last in the order of the last to the second coke oven bank. Conveyed and fed until the feed and feed of the in-coke oven chamber is complete,

A method is described in which the waste heat produced very uniformly in this way can be sent to the boiler plant so that the waste heat can be supplied very evenly to the boiler.

In a preferred embodiment, the method is configured such that the number of boiler units relative to the coke oven bank is exactly half so that the coke oven banks are paired and connected to the boiler.

This method is characterized by "transfer plan 2 * x / 1 * (x + 1) / 2". x represents the number of coke oven chambers per coke oven bank. 2 * x means a difference in the number of coke oven chambers in a controlled approach and means that the coke oven chamber 29 (difference 28 = 2 * 14) approaches after the coke oven chamber 1. As mentioned above, 2 * x is then the first coke oven bank of the coke oven chamber. Then, in the subsequent dosing cycle, the second coke oven chamber of the next coke oven bank, that is, the coke oven chamber 16 (difference 15 = 1 * (14 + 1)) is approached. Finally, in the subsequent transfer cycle, the third coke oven chamber of the first coke oven bank is transferred 2 ". If the number of coke oven chambers is 14, the transfer scheme is 28/15/2.

The transfer plan can be changed. Such a change is possible in the range where substantial homogenization of the incoming combustion gas takes place. For example, the feed cycle "2 * x / 1 * x / 1" is also possible. This will mean:

In the first transfer cycle, the first coke oven chamber of the first coke oven bank is transferred and introduced first, and if the number of coke oven chambers per coke oven bank is an even number then the first coke oven chamber of the coke oven bank. Each is continuously transferred and fed until the transfer and dosing of the first coke oven chamber of the last to second coke oven bank is complete,

In a subsequent transfer cycle, the first coke oven chamber of the next coke oven bank is transferred and introduced first, and then each of the first coke oven chambers of the next coke oven bank is sequentially transferred to the first coke oven chamber of the last coke oven bank. And conveyed and fed until the input is completed,

In a subsequent transfer cycle, after the coke oven chamber that is next in the order of the first coke oven bank is transferred and introduced, each of the same coke oven chambers in sequence in the next coke oven bank is next in the order of the last coke oven bank. Conveyed and fed until the coke oven chamber is finished

In the final transfer cycle, after the coke oven chamber last in the order of the next coke oven bank has been transferred and fed, the coke oven chamber in which each last coke oven chamber in the next coke oven bank is last in the order of the last coke oven bank. The feeding and feeding is carried out until the feeding and feeding of the food is completed.

In a preferred embodiment, the method is configured such that the number of boiler units relative to the coke oven bank is exactly half so that the coke oven banks are paired and connected to the boiler.

A simpler form of operation consists of accessing the first coke oven chamber of each of the following coke oven banks. Next, the transfer plan is "1 * x / 2". The transfer plan requires substantially less cost for the mover feed. However, the incoming combustion gas may be relatively less uniform. Stronger heat is applied to adjacent coke oven chambers. The transfer plan may mean:

In the first transfer cycle, the first coke oven chamber of the first coke oven bank is transferred and introduced first, and if the number of coke oven chambers per coke oven bank is even, each of the first coke oven chambers of the next coke oven bank is Continuously transferred and fed until the transfer and feed of the first coke oven chamber of the last coke oven bank is completed,

In a subsequent transfer cycle, the next coke oven chamber of the next coke oven bank is first transferred and fed in sequence, and then the same coke oven chamber in the sequence of the next coke oven bank is the same coke oven chamber in the sequence of the last coke oven bank. Is transferred and input until the transfer and input of

In the final transfer cycle, after the last coke oven chamber of the first coke oven bank is transferred and introduced, the coke oven chambers, which are each last in the sequence of the next coke oven bank, are sequentially transferred and fed into the last coke oven chamber of the last coke oven bank. It is transported and loaded until it is completed.

In a preferred embodiment, the method is configured such that the number of boiler units relative to the coke oven bank is exactly half so that the coke oven banks are paired and connected to the boiler.

In this way also homogenization of the combustion gas flow volume may be possible.

The boiler is used to generate steam to drive the turbine. This propulsion energy can be utilized arbitrarily. The propulsion energy is preferably utilized to generate electrical energy. To this end, the boiler device is equipped with suitable devices. These devices include heater installations, boilers, turbines, steam separators, shafts and generators. Additional equipment may be provided if it is desired to utilize mechanical energy in other ways.

When passing through the boiler device, the waste gas is preferably introduced into a gas cleaning device to minimize environmental pollution that may be caused by the coke production process. In particular, the gas cleaning equipment is preferably a desulfurization equipment for removing sulfur-containing compounds from the waste gas during the gas cleaning process. For example, the gas cleaning device may be a gas cleaning device to which a gas-absorbing solvent is applied.

Coal is charged into a coke oven chamber from the front by a coal input truck. As a result of the previous coking process, coal is still hot and no other process for coal carbonization is necessary. The door is closed at the start of the coking process. After the coking process, the coke is removed from the coke oven chamber. Depending on the coal cake height, the input density and the type of coke oven, the coking process basically takes about 20 to 90 hours. In an advantageous embodiment of the invention, the transfer takes place in the other direction of the coke oven chamber. Place the coke oven chamber door on either side of the coke oven chamber for quick and easy handling.

During feeding, the hot coke is transferred to the coke cooling car. To practice the present invention, the coke cooler can individually access each of the coke oven chambers. The coke cooler may be provided with cooling equipment. However, in order to be able to perform the discharge process quickly, it is desirable to have a facility for protection from high temperature. After transferring and discharging the high temperature coke, it is preferable to pass it along with the cooling vehicle to the complete cooling system. For example, the complete cooling system is a coke cooling tower. For example, it may be a coke dry cooling facility.

In order to carry out the method of the invention, an even or odd number of said coke oven chambers are connected to a coke oven bank. In an embodiment of the invention, the coke oven bank preferably comprises 6 to 34 coke oven chambers. In a particularly preferred variant of the embodiment of the invention, the coke oven bank comprises exactly 10 to 18 coke oven chambers. In a typical embodiment, the coke oven bank comprises 14 coke oven chambers. In order to supply hot waste gas to the boiler or boiler plant, the coke oven chamber is preferably connected to a paired coke oven bank. This connection is made through piping and appropriate collection facilities. Theoretically, it can also be inferred to connect a boiler or boiler plant to each of the three coke oven banks, but in this case the distribution of hot gases becomes even more difficult. Preferably, one boiler is connected to two coke oven banks. However, it is also conceivable to connect one boiler to one, three or more coke oven banks.

The method of the present invention provides the advantage of supplying hot combustion gases uniformly to the boiler or boiler installation of the coke oven apparatus. Therefore, steam is generated substantially uniformly by the boiler apparatus. As a result, the generation of electrical energy becomes much easier. This significantly reduces the generation of contaminants and pollutants from the coke oven apparatus. When power is generated by the process of the present invention, power generation is also uniform and optimized.
