DE2027376B2 - Leveling hole closure for the doors of horizontal chamber furnaces for the production of coke and gas - Google Patents

Description

The invention relates to a leveling hole closure Horizontal chamber furnace on the doors for the production of coke and gas.

There has long been a desire for horizontal chamber furnaces to produce coke and gas to make the filling level of the coal variable, e.g. to accommodate the different shrinkage capacity to adapt to the coal or to the gas conversion processes taking place in the gas collection room to influence by different choices of the height of the gas collection space or the location to take into account the upper gas reversal in the neighboring heating flues.

According to this wish, the path of the leveling or leveling bar, which on the machine side the battery is retracted through the reinserted door, be height-adjustable. This is also necessary if, after part of the fermentation period, there is a layer of fine coal be refilled and this should also be leveled.

In order to be able to change the height of the leveling bar, the so-called leveling opening must be used be designed accordingly in the door. You already have the grading hole for this purpose formed larger and in front of the same a height-adjustable or swiveling 180 ° Sealing frame arranged for the leveling door.

In this case you only need to give the leveling door, the so-called leveling hole cover, a height, which is sufficient for the leveling pole to pass through. But you can also use a Leveling door that closed the larger leveling hole by means of wedge-shaped inlaid in the leveling hole frame Bclagstücks reduce the opening of the leveling hole or move it in height.

With such an arrangement, however, a relatively large portion of the coke oven door is the exposed to the effects of heat occurring during operation, making the door unusable at an early stage will.

The aim of the present invention is to reduce the risk of damage to the furnace door by the effects of heat emanating from the interior of the furnace chamber.
For this purpose, a tubular housing, which allows the leveling pole to pass through, but also does not have a significantly larger opening, is attached within a door opening, the height of which is greater than that of the housing, at different heights on the door body by means of strips on both sides.

screwable. This closes the top and bottom of the housing parallel to the door seal lying flat Attachments to that with substantially horizontally extending bulges of the door body and the bottom or the roof of the housing after the furnace chamber to open, with refractory material Form lined heat protection rooms. The mentioned attachments can also consist of individual There are horizontal flat bars that are above or below the strips of the housing on Door bodies can be screwed on.

The housing, which protrudes as far as possible into the furnace chamber, protects the leveling door frame and the leveling cover largely from the effects of heat; those above and below the case Due to the heat protection rooms in front of the door, lying parts of the door cannot be inadmissibly high Accept temperatures. For better support of the fireproof lining of the heat protection rooms an upper one on the inner edge of the housing roof and a lower one on the inner edge of the housing bottom continuous nose be provided.

In the drawings is the upper part of a coke oven door with the leveling hole lock on it shown, namely shows

From the furnace head, which is through the furnace door

closed chamber 11, the heating walls 10 can be seen, the furnace opening is; completed by the door frame 12, which is square in cross section. The oven door is formed by a U-profile which is formed from the base plate 13 and the two flanges 14 will. The sealing edge 15 can be seen on the side flanges, and the one on the front of the door frame 12 comes to the sealing support. 16 is the one made up of several layers of refractory bricks Door stopper, through which the metallic door body 13, 14 largely protects against the effects of heat is shielded, which extend from the interior of the chamber. Around an opening for the retraction of the leveling pole To create, there is a rectangular opening in the base plate 13 of the door, which for example can be seen in Fig.2. This opening is limited at the bottom by an almost horizontal bulge 18 and an upper bulge 17 of the door body? those from one side flange 14 to the other run through.

The essential element of the innovation is a housing, the height and width of which are just dimensioned so _that ; _ß the leveling bar can extend and retract.
