Description
Method and Apparatus for Elimination of Charging Gases that Form During Coal Charging of Coke Oven Batteries The invention concerns a method and apparatus for eliminating charging gases that form during coal charging of coke oven batteries.
It is known from Gluckauf, 122 (1986), No. 5, pp.
367-374 that the charging gases that form during coal charging of coke ovens can be fed to the gas collecting main by the partial vacuum created from pressurized water spraying or stream injection via the standpipe of the oven being charged, and via a jumper pipe connectable to so-called ministandpipes on the opposite end of the chamber and travelling by means of the larry car, through the gas collecting space of a neighbouring chamber in which relatively little gas is evolved at this point via its standpipe.
In this process the gases are conveyed horizontally to the standpipe through the coke oven chamber. Constrictions for gas flow and thus increased charging gas pressures in the gas collecting space (space above the coal and oven roof} occur on this account primarily at the end of the charging phase and during levelling of the coal. Gas pressures develop on this account within the oven chamber and at the charging holes, which can lead to more or less severe charging gas emissions, which develop mostly at the charging holes between the charging hole frame and so-called charging telescope.
To achieve emission-free or at least low-emission charging despite these conditions it is essential to operate offtake via the standpipe with a correspondingly high partial vacuum. However, this again means that larger amounts of coal particles are entrained into the gas collecting main and adversely affect the purity of the coal tar.
Since one ministandpipe is required for each chamber on the side of the chamber opposite the main standpipe, the investment costs for this method are relatively high, in particular, a corresponding refit of a coke oven battery is possible at best after shutdown of the concerned oven chambers.
Each ministandpipe is provided with a cover. Sealing ordinarily occurs with a water bath. In addition to the investment costs for these additional standpipes, a significant cost must be incurred for cleaning and maintenance, since contamination of the water bath occurs during transfer of the gas stream and the covers must be cleaned.
A similar generic system is known from US-A 4,004,702 in which the charging gas stream is supposed to be reduced by a constriction on the charging telescope and better distributed in the coke oven chamber, accepting a longer charging time. A
transfer device with a jumper pipe for additional charging gas distribution can be used here.
The underlying task of the invention is to devise a method and apparatus of the type mentioned in the introduction with which emission-free or at least low-emission charging of coal is made possible with comparatively limited technical expenditure and minimal operating costs.
The invention provides a method for removal by suction of charging gases that form during charging with coal one of a plurality of chambers in a coke oven battery using a larry car, in which the charging gases are fed through the gas collecting space of a neighbouring oven chamber and through a corresponding standpipe into the gas collecting main of the coke oven battery via both the standpipe of the oven chamber being charged and via a jumper pipe travelling with the larry car, wherein part of the charging gas formed in said one oven chamber is drawn of=f via one or more charging holes of said one oven chamber by means of known charging telescope therein, said part being collected by means of one or more gas collection lines and transferred by means of one or more charging gas transfer telescopes into a gas collecting space of a second of said oven chambers and from said gas collection space of said second oven chamber via a standpipe into the gas collecting maim of the coke oven battery.
From another aspect, the invention provides apparatus for removal by suction of charging gases that form during charging of a coke oven battery with coal using a larry car wherein ;aid larry car includes at least one charg-ing telescope that is adapted to change coal into a selected one of a plurality of chambers in said coke oven battery, and a transfer device that can be connected to a second chamber in said coke oven x>attery, wherein each charging telescope has an annular gap chamber that is connected via at least one charging gas collection line to at least one transfer telescope that is arranged in a position on the larry car to effect fluid connection of said at least one transfer telescope to at least one charging hole in said second chamber in said coke oven battery.
Preferably only a single gas collecting main is used which is connected to all of the charging holes of the coke oven chamber being charged and is connected to a single charging hole of the neighbouring oven chamber through a single charging ga:c transfer telescope. The second oven chamber may be one that is adjacent or non-adjacent the oven chamber that is being charged.

The underlying task of the invention is to devise a method and apparatus of the type mentioned in the introduction with which emission-free or at least low-emission charging of coal is made possible with comparatively limited technical expenditure and minimal operating costs.
The invention provides a method for removal by suction of charging gases that form during charging with coal one of a plurality of chambers in a coke oven battery using a larry car, in which the charging gases are fed through the gas collecting space of a neighbouring oven chamber and through a corresponding standpipe into the gas collecting main of the coke oven battery via both the standpipe of the oven chamber being charged and via a jumper pipe travelling with the larry car, wherein part of the charging gas formed in said one oven chamber is drawn of=f via one or more charging holes of said one oven chamber by means of known charging telescope therein, said part being collected by means of one or more gas collection lines and transferred by means of one or more charging gas transfer telescopes into a gas collecting space of a second of said oven chambers and from said gas collection space of said second oven chamber via a standpipe into the gas collecting maim of the coke oven battery.
From another aspect, the invention provides apparatus for removal by suction of charging gases that form during charging of a coke oven battery with coal using a larry car wherein ;aid larry car includes at least one charg-ing telescope that is adapted to change coal into a selected one of a plurality of chambers in said coke oven battery, and a transfer device that can be connected to a second chamber in said coke oven x>attery, wherein each charging telescope has an annular gap chamber that is connected via at least one charging gas collection line to at least one transfer telescope that is arranged in a position on the larry car to effect fluid connection of said at least one transfer telescope to at least one charging hole in said second chamber in said coke oven battery.
Preferably only a single gas collecting main is used which is connected to all of the charging holes of the coke oven chamber being charged and is connected to a single charging hole of the neighbouring oven chamber through a single charging ga:c transfer telescope. The second oven chamber may be one that is adjacent or non-adjacent the oven chamber that is being charged.
In the meaning of the invention the second or "neighbouring" oven chamber is one from which the amount of gas to be taken off from its gas collecting space is so small that the amounts of charging gas transferred to it can also still be taken off; a directly neighbouring oven chamber would therefore not be involved, but rather one that is, say, two or three chambers away.
As known from the prior art, part of the charging gases are drawn horizontally into the standpipe of the oven chamber being charged and from there sent to the gas collecting main. Charging gases are additionally fed from the oven chamber in the vertical direction via several, preferably via all charging holes, i.e., distributed over the chamber length, into another oven chamber by means of a special transfer system and from there likewise fed to the gas collecting main. Since the charging gas is taken off at different sites distributed over the length of the oven, high charging gas pressures that can result in emissions can no longer occur.
The amount of charging gas increases continuously during the charging time (usually between 50 and 120 seconds, depending on the charging system and the amount of coal). The pressure and temperature on the charging telescope is also increased accordingly. In order to allow for this, according to a modification of the invention the offtake capacity is adjusted to the amount of forming charging gas by recording the naturally occurring pressure and/or temperature changes on the charging telescopes.
According to another embodiment of the invention the offtake capacity can also be controlled via the time trend during the charging time. The transfer system according to the invention is fully installed on the larry car and consists of the following components.
- charging telescopes with annular gap chambers for vertical charging gas offtake from the oven chambers;
- a charging gas collecting main connected to the annular gap chamber;
- a charging gas feed device in fluid connection with the charging gas collecting main, preferably a blower, such as a hot gas blower with controllable volume capacity as well as, - a single charging gas transfer telescope for fluid connection of the charging gas collecting main to a single charging hole of an oven chamber spaced from the oven chamber being charged.
In addition the following is advantageously provided:
- at least one plenum cooler for charging gas temperature reduction of the charging gases being transferred;
4a _ 2~~~0~~
- shutoff dampers in the pipeline system between the charging telescopes and the transfer telescopes;
- temperature and/or pressure sensors for blower regulation or control.
The oven roof of the charging hole of the neighbouring, oven chamber, through which the corresponding part of the charging gas is transferred into the gas collecting space of the neighbouring oven chamber, is raised with an electromagnet incorporated in the transfer telescope or by means of a device outside of it and repositioned after completion of the transfer process. The charging hole of a neighbouring oven chamber to be used for charging gas transfer can be chosen corresponding to the space relations on the tarry car. A limitation of the transfer site to the coke side, as in the known jumper pipes, drops out, i.e., any of the, say, 3 to 5 charging holes of one of the neighbouring, oven chambers can be utilized. Preferably the transfer site lies close to the standpipe in order to achieve the least possible pressure losses.
A particular advantage of the invention is that the charging gas transfer telescope according to the invention can be a relatively simply designed device in which it is merely ensured that a sufficiently gas-tight connection can be produced between the preferably single charging gas collecting main and the preferably single (coal) charging hole of the "neighbouring" oven chamber. Sealing and handling problems, like those that occur in the known jumper pipes and are especially troublesome during, spanning of several oven 2~~~3~15 chambers because two gastight pipe connections must be made simultaneously, do not occur in the charging gas transfer telescopes according to the invention.
The invention is further explained below with reference to the drawing:
Figure 1 shows a perspective schematic cutaway of a coke oven battery with charging gas extraction, Figure 2 shows a schematic view of a charging gas transfer telescope according to the invention partly in vertical cross section.
It follows from Figure 1 that a coke oven chamber 100 of a coke oven battery 101 is charged with coal 30 by means of a larry car 103 traveling on rails 102 on the roof of the coke oven in which a gas collecting space 31 remains beneath the coke oven roof 32. As indicated by arrow A part of the charging gases are withdrawn via charging; holes 1 2 3 and 4 into a known charging telescope with annular gap chambers 5, 6, 7 and 8 (see detail in Figure la). For reasons of clarity only charging telescopes 5 and 8 are shown schematically. The charging gases are conveyed through the annular gap chambers to a gas collecting line 9 10 11 17 and 20 via pipelines with shutoff dampers 12 13 14 and 15. The charging gases are cooled in a so-called plenum cooler 16 as required. A hot gas blower 18 with controllable drive 19 is arranged behind plenum cooler 16. The charging gases are then fed via line 20 and a charging gas transfer telescope 2 1 to a charging hole 22 of a neighbouring oven (Figure 2) and as shown by arrow C drawn into the gas collecting main 24 of the coke oven battery via a 2~586~5 standpipe 23.
The other part of the charging gases as shown by arrow B are drawn into the gas collecting main 24 via a standpipe 25.
Because of division of charging gas offtake according to the invention pressurized water spraying or steam injection into the standpipes can be reduced so that energy is saved and discharge of coal particles is reduced.
Figure la shows a cutaway enlargement of the charging telescope with annular gap chamber 5. The right half of the figure shows the charging telescope in the lowered position and the left half in the raised position. The charging telescope 5 consists of flexible seal 5A two telescope tubes 5B and 5C and a sealing ring 5D that can be mounted gas-tight on the opening of charging hole 1 for the charging hole frame on oven roof 32. Telescope tubes 5E and 5F
are arranged in telescope tubes 5B and 5C so that an annular gap chamber R opened downward is formed on one side between telescope tubes 5B 5C and on the other side between telescope tubes 5E 5F to which a pipeline 5G is connected which is connected to gas collection line 9. Coal is charged into the coke oven chamber 100 via telescope tubes 5F and 5E through a coal feed device 5H (arrow D). The charging gases, as shown by arrow E, are withdrawn into the gas collection line via annular gap chamber R and pipeline 5G.
As is apparent from Figure 2, a charging gas transfer telescope 21 preferably rigidly connected to each individual charging gas collection line 20 consists of a 215~~~15 flexible seal 21A, two telescope tubes 21B and 21C and a sealing ring; 21D that can be mounted essentially gas-tight on the opening of a charging hole 22 for the charging hole frame on the oven roof 32. An automatically functioning charging hole cover lifting and placement device is preferably provided in the region of the charging gas transfer telescope on larry car 103 but is not expressly shown in Figure 2, since it is known.
