Definitions
- the invention relates to a method for compensating flue gas enthalpy losses of "heat-recovery" coke ovens, which extract steam or heated water from the flue gas produced during coking, wherein the operation of the coke oven chambers can be interrupted for a certain time, so that the coke oven chamber contains no or a reduced amount of coke, and unwanted cooling of the coke oven chambers is avoided by additional burner, which heat the coke oven chambers during the stoppage on, with at least one further compensation burner, which is located outside the coke oven chambers, the reduced amount of heat in The flue gases is compensated, so that the boilers are supplied with a constant amount of heat.
- the US 4045299 A describes an arrangement of coke oven chambers with lateral coke oven chamber walls, frontal coke oven chamber doors, loading openings in the ceiling and a coke oven chamber floor on which the coal cake is loaded for coking.
- Below the floor are secondary air soles, which communicate via channels in the sides of the coke oven chamber with the gas space above the coke cake.
- the secondary air soles communicate with a heating chamber equipped with externally heated burners, whereby unburned residual gases in the coking gas can be completely burned before being placed in the recuperator.
- the heating chamber may, if necessary, be supplied with coking gas from the gas space above the coke cake, so that the flue gas is always completely burned and provided with a temperature suitable for flue gas combustion.
- the design is only suitable for "non-recovery" coke ovens and must be operated continuously to ensure a correspondingly high temperature of the flue gas.A way to gain steam and to ensure a constant temperature of the flue gas is not described.
- the invention achieves this object by means of at least one compensation burner, which is arranged outside the coke oven chamber, which introduces the heated flue gas into the flue gas channel, so that the enthalpy of heat enthalpy resulting from a scheduled or unscheduled interruption of operation of the coke oven chambers is additionally caused fed flue gas can be compensated.
- a flue gas with an always constant temperature is provided in the boilers, so that the boilers can be operated economically.
- the one or more compensation burners can be arranged outside the coke oven chamber at any point. However, these are preferably arranged in the boiler prior to entry in the vicinity of the flue gas distributor.
- Particularly claimed is a method for the compensation of flue gas enthalpy losses of "heat-recovery" coke ovens, wherein A number of coke oven chambers are connected to a coke oven bank communicating with at least one boiler utilizing the hot flue gas from the coke oven banks to produce steam or heated water; and
- the coking gas is used to heat the coke cake by combustion with air and to supply the heat necessary for coking to produce a hot flue gas
- the individual coke oven chambers are kept warm during the scheduled or unscheduled interruption of operation with at least one externally fired auxiliary burner, so that even during the interruption or delay of operation, a hot flue gas is provided, which comes from the flue gas of the burner, and which is characterized that
- the heat flow of the flue gas at interruption or delay of operation is typically reduced by up to 50 percent without the additional compensation burner in the so-called holding operation outside the coke oven chambers.
- this is only a guideline. This is due to the fact that the capacity of the auxiliary burner in the coke oven chambers is often not sufficient to keep the flue gas consistently high temperature.
- the compensation burners are arranged in an advantageous embodiment in front of the flue gas distributor, which is located in front of the boiler.
- the heat flow of the flue gas is attributed to 100 percent or almost 100 percent of the heat flow of normal operation. This is done temporally constant.
- the power of the compensation burner can be regulated automatically in dependence on a temperature sensor.
- the one or more compensation burners outside the coke oven chambers are preferably operated with a hydrocarbonaceous fuel. This is natural gas in a preferred embodiment. In one embodiment of the method according to the invention, however, it is also possible to operate the additional compensation burner (s) with coke oven gas. In a further embodiment of the method according to the invention, it is furthermore possible to operate the additional compensation burner (s) with vaporized liquid hydrocarbons or vaporized hydrocarbon-containing fuels.
- liquid gas such as LPG (Liquefied Petroleum Gas or Low Pressure Gas)
- LPG Low Pressure Gas
- the heat flow or enthalpy of the flue gas is typically used to generate steam through the boilers.
- the steam is then used to generate electricity.
- the compensation burners are arranged directly in front of the boiler (s).
- the compensation burners are located between the flue gas manifold and the one or more boilers a lockable emergency fireplace, which has a shut-off device. Then the additional compensation burner (s) are placed directly in front of the emergency chimney.
- the compensating burner (s) are located in the flue gas duct between the coke ovens and the boiler.
- the compensation burners can be present in any number and in any combination as far as the arrangement of the compensation burners is concerned.
- the invention has the advantage of providing a method which provides a flue gas at a consistently high temperature during the stoppage of coke oven chambers and at the same time prevents unwanted cooling of the coke oven chambers. This allows the boilers to be operated economically.
- FIG. 1 shows an arrangement of four coke oven chambers (1) which are combined to form a coke oven bank (2). These coke oven chambers (1) are set burners (3) equipped. The coke oven chambers (1) are empty after expressing the coke cake. The hot flue gas (4) is led into the flue gas duct (5), which finally leads into the boiler (7) via a common flue gas duct (6).
- the common flue gas duct (6) can be equipped with a flue gas distributor (8) in front of the boiler (7).
- the hot flue gas (4) is used in the boiler (7) to generate steam, which in turn is used to generate electricity (9).
- the boiler (7) must be supplied with flue gas (4), which has a constant temperature over the entire time.
- the cooled (11) is carried out after flowing through the boiler (7).
- FIG. 2 shows the same arrangement of four coke oven chambers (1), which are combined to form a coke oven bank (2).
- the hot flue gas (4) is passed into the flue gas duct (5), which finally leads via a common flue gas duct (6) into the boiler (7).
- the common flue gas duct (6) is equipped in front of the boiler (7) with an emergency chimney (12), which can be shut off when operating the compensation burners (10a-c) with a suitable device (12a).
- the compensation burners are arranged here (10a) both in front of the emergency chimney (12) and directly in front of (10b) the boiler (7) and (10c) on the outlet channel (5) for the exhaust gas (11), the additional flue gas in the common flue gas channel (6) feeds.
- the cooled exhaust gas (11) is carried out after flowing through the boiler (7).
