Definitions
- the invention relates to a coking plant according to the non-recovery process or the heat recovery process for the production of coke from coal.
- High throughput is of particular importance for the economy of a coking plant according to the non-recovery method or the heat recovery method, collectively referred to below as NR / HR. This is mainly because in this technology due to the slight influence of the combustion gas release over the conventional horizontal chamber technology always a prolonged operating time, that is to say a lower cost-effectiveness. The speed of this
- Coking technology can only be influenced by uniformly feeding the air into the process in several stages, thus optimizing combustion.
- FIG. 1 An example of the refractory structure in the lower furnace is presented in the plan view in Fig. 1.
- the raw gas / waste gas mixture formed in the combustion chamber of the top furnace is fed to the bottom channels in the bottom furnace in 2 to 20 downcomer channels per furnace. There it is completely burned with the addition of combustion air.
- the heat generated there is the coking of the coal charge from below, which ensures a shorter operating time and high performance of the furnace.
- this so-called secondary air is sucked through the openings on the front sides, which is offered via a branched vertical channel system the actual Sohlkanal2020 used for secondary combustion of combustible gases. This creates a variety of short individual flames in the Sohlkanälen.
- the procedural measure of the exhaust gas recirculation in the combustion chambers of the NR / HR furnace is proposed.
- an internal exhaust gas recirculation in the bottom channel system of the lower furnace can be used.
- a partial exhaust gas stream is branched off immediately before its final evacuation from the furnace in the Sohlkanal and returned via a channel system or one or more openings upstream in the Sohlkanal.
- the drive for the exhaust gas recirculation forms the pressure difference between the upstream and the downstream Sohlkanal, which causes a return to the upstream channel.
- the pressure difference is explained by the higher exhaust temperature and thus the lower density in the upstream Sohlkanal.
- This measure causes a delay of the secondary combustion, extends the individual flames in the Sohlkanal and promotes the equalization of Ausbrand characterizing and the heat release in the lower furnace.
- the partial pressure of oxygen in the Sohlkanal2020 the furnace is lowered, resulting in a reduction of the thermally formed NOx exhaust gas portion results. This is due to that due to the addition of exhaust gas, the temperature of the media and thus the thermal NO formation in the bottom channel is reduced.
- exhaust gas only in the further flow, i. to be taken externally from the channel system of the furnace and returned via a blower of the furnace chamber, the downcomers or the Sohlkanalsystem in the lower furnace.
- exhaust gas only in the further flow, i. to be taken externally from the channel system of the furnace and returned via a blower of the furnace chamber, the downcomers or the Sohlkanalsystem in the lower furnace.
- further components which are harmful to the environment or to the process can be withdrawn from the exhaust gas before they are returned to the furnace.
- FIGS. 2a and 2b show the flow guides and the formation of flames in the FIGS
- FIG. 4 shows a further plan view of the sole system of 2 adjacent coke ovens.
- FIG. 5 shows a further front view of the sole system of 2 coke ovens adjacent to one another
- Fig. 2a shows the flow guides and the flame formation in the Sohlkanälen according to the prior art.
- the raw gas-exhaust gas mixture of the upper furnace from the downcomers 5 and burns in the flames 11 and 12 with the air from the Sekundär Kunststoffaustritten 13 in the Sohlkanälen 8 and 9.
- single-circuit flow openings 10 are provided which a Allow backflow of the exhaust gas, which improves the geometry of the flames 11 and 12 and set the advantages of the invention in terms of pollutant formation.
- FIG. 3 shows an example of a sole-channel geometry with a single opening 10 for generating an internal exhaust gas recirculation in the lower furnace.
- FIG. 4 shows an example of a sole-channel geometry with two individual openings 10 for generating an internal exhaust gas recirculation in the lower furnace.
- FIG. 5 shows two examples of external exhaust gas recirculation possibilities, in which blowers 14 each provide for the return.
