Description

Regenerative coke oven with constant flame direction. With regenerative coke ovens with constant flame direction in the heating flues there are already - compensation channels for the burnt gases withdrawn from the flues and for those from the burners Combustion air to be supplied has been proposed. According to the invention (the Each has a collecting duct for the waste heat and a distribution duct for the combustion air between (the two regenerators, @die in a known manner below and in or Run lengthways of the furnace battery, laid on top of each other. The air supply openings at the ends of the battery and the fox channels leading to the chimney each can be shut off by a special slide. This is an extensive Allows cooling and protection of the slide.

Illustrate on the drawing: Fig. I the longitudinal section through the heating wall according to the line A-B of Fig. 3, Fig. z a longitudinal section through a Furnace chamber according to the line C-D of Fig. 3, Fig. 3 a cross section according to the Lin-i, e E-F of Fig. I,.

Fig.q. a plan according to; the line GH of the AM. 3.

The furnace shows a known design of the heating walls and chambers. The special interlinking of the regenerators and equalization channels for the exhaust gases and fresh air can be seen in Fig. 3. When the A gate valve a is open, the fresh air can enter channel b and distribute itself over the latticework of regenerator c. The preheated combustion air flows from the regenerator into the lower duct d and, when the gate valve e is open, through the connecting duct f into the compensation duct. Here the combustion air is distributed to the ducts h leading to the individual heating walls and exits the sole ducts i through the openings h into the heating flues. , The waste heat is conducted above the heating flues through ducts 1 to the sloping flues m and to the equalization duct n. From this channel the waste heat goes through the connecting channel o 'when the shut-off valve p1 is open. The channel b1 above the latticework of the regenerator cl. From this regenerator the heat goes through the lower channel dl to the fox x1 and when the shut-off valve y1 is open to the chimney z. After .this run has come to an end,. for the purpose of reversing the tension, the opened shut-off valve is closed and the opposite one is opened. All shut-off valves are in their closed state on the one hand exposed to the radiant heat of the furnace interior and on the other hand to the fresh, not yet pre-warmed smell of combustion flowing past. The open slides are removed from the inner furnace heat and are in the normal air space.

With s and: s1, excess Air can be discharged. For closing and regulating the waste heat from the individual Furnaces can have the puffs placed at the head ends instead of in the middle of the furnace will; they are then passed horizontally by a horizontal one below the heating wall Channel connected to equalization channel n. Closing and regulating takes place -in the same way as with the previously mentioned channels for the combustion air next to the s and s1 digits.

It should also be noted that channels b, b and d, dl too. next to the Regeneratorem can be arranged, making the latter larger. The connection among themselves there will then be given through small, lying canals.

Claims (1)

PATENT CLAIMS: i. Regenerative coke oven with constant flame direction in (the heating flues and below the furnace battery in -their longitudinal direction- Regenerators and equalization channels for distribution or combustion air and the Waste heat, characterized in that the exhaust ducts for the air (g) and for , the waste heat (s) between the regenerators are on top of each other. Embodiment of the regenerative coke oven according to claim i, characterized in that the fox channels (x, x1) in front of the chimney (z) and the air inlets (a, d) for the regentrators can be shut off by a slider each.
