Description

In the proposed regenerative nechi with separate for each vertical stroke, regenerators for heating the air, separate dl of each vertical stroke are also used, which heat the lean gas.

In FIG. 1 shows a view of the proposed coke oven in a transverse vertical section; FIG. 2-cuts along the lines DC and E F on 1 | h1g. 1, fig. 3 is a modified form of the oven in a transverse vertical section; FIG. 4 is a sectional view of the CD line in FIG. 3, FIG. 5 shows a section along the EF line in FIG. 3 and FIG. 6 is a sectional view of the GH line in FIG. four.

The coke oven consists of a series of jf chambers for coking and located between the vertical heating passages S. Each vertical run 2 corresponds to a regenerator 24 for heating the heating gas and a regenerator 6 to warm up the air required for combustion. At the same time, gas is supplied to each regenerator 24 by means of pipes 26 branching from distribution pipe 25 in the same way to regenerators 6 air is supplied through pipes 22 separated from distribution pipes 21; the regulation is made from the channels located in the foundation, by means of taps 27 for gas and air valves 23. When changing the direction of movement of the heating gases, the exhaust gases from the regenerators 24 exit through the channel 28, and the gases from the air-heating regenerators 6 exit through the channel 8 to the boar. By arranging the valves in channels 28 and 8, it is possible to individually regulate the exhaust gases from the heating regenerators 6 and 24. Such a device of the furnace makes it possible to heat the heating gas, depending on its calorific value and its composition, preheating; regenerators emit waste gases in an amount that corresponds to the intended heating of the heating gas. With a gas with a significant calorific value, it is possible to pass waste gases only through air chambers, in which case gas and gas chambers work as recuperative gases.

When depicted in FIG. 1 and 2 regenerative coke oven with lower

burners, the heating passages of one half of the crawfish are alternately subjected to direct heating, while the exhaust gases exit through the heating passages of the other half of the furnace, for which there is a CUTTLE upper horizontal channel for transferring the flue gases from one half to the other. This is a disadvantage, since the device of the said horizontal channel weakens the heating walls and, in addition, heated by alternately with a direct flame and a full half of the tenkn thermal gases, the thermal equalization occurs only when switching, i.e., approximately every half hour. To eliminate these drawbacks in the form of the furnace shown in FIG. 3-6, the heated air and the heated gas are brought to separate combustion points in such a way that alternately even and odd passages are directly heated while the exhaust gases descend along unheated passages. As a result, continuous thermal leveling occurs between the individual heating passages. With such a device, for the operation of each individual furnace it is necessary that for each such furnace unit four bottom channels should be provided, which should run along the entire length of the furnace chambers. For this purpose, the air preheaters are lower than the gas preheaters and the four above mentioned bottom channels are located under the air preheaters. Due to the considerable height of the heaters, their cross-section is reduced, which enhances the stability of the retaining walls and improves the sealing of the heating chambers relative to each other.

The horizontal coking chambers 1 are located between the heating walls, in which every two heating passages S and 5 are connected in one pair, so that when run 2 is subjected to direct heating, the exhaust gases pass along the adjacent run 3 and each turn 2 is fed gas heated by regenerators 24, each stroke by 5 regenerator 24a, gas is supplied to regenerators 24 and 24a alternately through pipes 26 and 26a connected to gas lines 25 in the foundation channels (phage 1 and 2). The strokes S and 5 are connected, each, in addition, with regenerators 6 or 7 for air, to which air is supplied from the foundation channels through pipes 22, 22a, where air inlets into pipes 22, 22a from the foundation channels are provided with air nozzles, which alternately open and close.

All regenerators 24 for gas located in the same row are connected to channel 58, yet regenerators 24a in one row are connected to channel 28a ,, 1 and just as all regenerators 6 for air in one row are connected to channel 8, and all the regenerators are 7 with channel 9. The channels 28 and 8 go out into the hog 18, and all the channels 28a and 9 into the hog 18a. In front of the chimney, switching valves are placed in the channels 18 and 18a, by means of which the said channels are alternately connected to the pipe.

At one of the directions of heating the gas through the pipes 26 and the lattice spaces 24 enters the heating passages 2, where the air is supplied through the pipes 22 and the regenerators 6. The gases burn, the passage upwards through all passages 2 of one wall, passes at the upper end to strokes 5 move downward through them and already as waste gases, they drop partly through generators 24a and channels 28a and partly through regenerators 7 and channels 9 to the boar 18a, and from there into the pipe. After approximately thirty minutes, the heating direction is switched and the movement of gases occurs in the opposite direction. All switching bodies are rearranged simultaneously with a winch.
