Description of the invention: [Technical field to which the invention pertains] The present invention relates to a method for compensating a heat recovery coke: a flue gas heat, which is used in a flue gas generated during carbonization of coal. Recycling steam or hot water 'because it may interrupt the operation of the coke oven chamber for a period of time, causing the coke oven chamber to contain no coking coal or only a reduced amount of coking coal, and with additional burners, the coke oven chamber can be avoided Unwanted cooling occurs; these additional burners are used to maintain the heat of the coke oven chamber during the interruption of the operation, and compensate for the flue gas by at least one additional compensating burner disposed outside the coke oven The reduced thermal energy causes the boiler to be supplied with a fixed amount of thermal energy. [Prior Art] The operation of the coke oven chamber is performed in a cyclic manner, which means that the coke oven must be packed cyclically, and the coal is heated to generate coal char, and the most: coal char product is from the coking chamber. Introduced to take advantage of the final coal char product after carbonization of the coal. It often happens that the condition is that after the coking coal is introduced, the coke oven chamber is not filled immediately, = the storage capacity cannot be obtained, or because the manufacturing process must be rooted. Therefore, the coke oven chamber is empty for a period of time, and the coal char is placed. The cooling of the coke oven chamber must be avoided. As a result, the L1 will deteriorate and the structural material of the coke oven chamber will be damaged. However, heating the coke oven chamber requires additional cost. Black has to heat up the heat of I, thus making the cost quite high. 201120381 In principle, multiple burners can be installed in the coke oven chamber. These furnaces are heated by external sources, so that the coke oven chamber is not interrupted or Cooling occurs during the delay. However, as a result, a flue gas having a temperature drop of L is generated, which becomes troublesome because the flue gas from the coke oven chamber of the heat recovery coke oven is used in a so-called boiler to generate steam. Hot water, if the temperature of the flue gas fluctuates and is different from the normal operation of the coke oven, then the boiler cannot be operated in a more economical way. The capacity of the extra burner in the coke oven chamber is often insufficient to use the flue. The flue gas in the gas passage is heated by the step. According to the prior art, a number of methods for heating the flue gas in the coke oven chamber are known. U.S. Patent No. 4,045,299 discloses a structure of a coke oven chamber having a lateral coke oven chamber wall, a forward coke oven chamber door, a loading hole at the top, and a coke oven chamber floor, wherein the coal block is placed The bottom plate is used for carbonization of coal. Below the bottom plate, there is a secondary air bottom which passes through the passage provided at the side of the coke oven chamber and stagnates in the free gas space of the furnace above the coke oven. Then, the two-person air bottom is stagnated in a heating chamber provided with an externally heated combustion furnace, whereby these can be made before the unburned residual gas in the coke gas is sent back to the recuperator The unburned residual gas is completely burned off. If desired, coking gas from the free gas space of the furnace above the coke oven can be supplied to the heating chamber so that the flue gas can be burned completely and has a temperature suitable for combustion of the flue gas. However, this structural design is only applicable to “non-recycling” coke ovens and must be operated continuously to ensure that the flue gas has a sufficiently high temperature. This U.S. patent does not describe how to recover steam and ensure a fixed temperature of the flue gas as in 201120381. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method for enabling a flue gas having a fixed high temperature to generate steam or hot water during operation interruption of a coke oven chamber, and at the same time preventing coke ovens. Unwanted cooling occurred in the room. In order to achieve the above object, the present invention provides at least one compensating burner on the outdoor side of the coke oven, and introduces the heated flue gas into the flue gas passage, so that the coke oven can be compensated by additional flue gas. The enthusiasm generated by interruptions in scheduled or unscheduled operations in the room. Thereby, it is possible to provide a flue gas having a fixed temperature in the boiler, so that the weaving can be operated in a more economical manner. The compensating burner may be placed at any position on the outdoor side of the coke oven, however, a preferred position is located upstream of an inlet adjacent to the flue gas distributor into the burner. The invention particularly claims a method for supplementing the flue gas enthalpy of a heat recovery coke oven, wherein: the eclipse coke oven chamber is connected into a coke oven group, and the coke oven group is connected to a / boiler 'at least one The pin furnace utilizes hot flue gas from the coke oven group to generate steam or hot water; the operation of the coke oven chambers is periodically interrupted to remove coking coal from the coke oven chambers; in normal operation' Using the combustion of the coke gas and air to heat the coke and provide the heat energy required for the carbonization of the coal, so that a heat of 201120381 flue gas can be generated; and during the scheduled or unscheduled operation interruption, the coke ovens The chambers are respectively insulated by the at least one external ignition-heated additional combustion furnace, so that during operation interruption or delay, a hot flue gas generated from the flue gases of the combustion furnaces may also be supplied; The reduced heat flow compared to normal operation is supplemented by at least one additional compensating burner at the outdoor side of the coke oven, so that the steel furnace can provide a comparison with normal operation. More fixed heat flow. During the operation interruption or delay, during the process of the outdoor side of the coke oven, there is no additional compensation for the so-called hot idle state of the furnace (h〇t_idle(7), the heat flow of the flue gas is generally reduced by up to Fifty, but this is only a reference value. The reason is that the capacity of the additional burner in the coke oven chamber does not keep the flue gas at a fixed high temperature. In an advantageous embodiment of the invention, the compensating burner system is set. At the upstream of the flue gas distributor, the flue gas distributor is located upstream of the combustion furnace. Depending on the type of structure of the compensating furnace, the flue gas is positively corrected (4). Or close to a hundred = 100' extension - the point occurs in a momentary fixed manner. Depending on the type of structure, the performance ratio of the compensating burner can be automatically changed to a function of a temperature sensor. The compensating burner located on the outdoor side of the coke oven is operated by a fuel containing a f-hydrogen compound. In the preferred embodiment the fuel is natural gas. However, in the method of the present invention In an embodiment, the additional compensating burner may also be operated with coke oven gas in 201120381. In another embodiment of the method of the invention, it may also be by vaporized liquid hydrocarbon or hydrocarbon-containing. Gasification of the fuel to operate the additional compensating burner. In another embodiment of the method of the invention, the additional compensating burner may be operated by a liquefied gas, for example a so-called LPG (liquefied natural gas or low pressure gas) may be used. 'The gas can be maintained in a liquid state by pressure or low temperature. The heat flow or heat of the flue gas is utilized, and steam is generated by the boiler, and then the steam is used to generate a current. In an embodiment of the invention, the combustion is compensated. The furnace system is directly disposed upstream of the boiler. In another embodiment, a lockable emergency smoke provided with a locking device is disposed between the flue gas collection pipe and the boiler, and the additional compensation burner is directly disposed. In the emergency smoke from the upstream. In another embodiment of the invention, the compensating burner system is disposed in the exhaust pipe of the flue gas and is located between the coke oven and the boiler The number of compensating burners and their combination of configurations can be arbitrarily selected. The present invention has the advantage that the method of the present invention can provide flue gas having a fixed high temperature during operation interruption of the coke oven chamber, and at the same time prevent coking Unwanted cooling of the furnace chamber. Therefore, the boiler can be operated in a more economical manner.
