Coke-oven Gas Exhausters
Coke-oven gas exhausters are used for suction of gas from coke ovens and for its conveying through pipelines to chemical products trapping equipment.
Application branches:
- Metallurgy
Design features
- As for the design features, the compressors are single-case, single-shaft, six-stage compressors with compressed air cooling after every two stages;
- Gear is the single-stage step-up herringbone cylindrical gear transmission;
- Performance is controlled using the throttle valve;
- Connecting and installation dimensions of the K 250 and TsTK 275/9 compressors are the same for the foundation;
- Lubrication system in K 250, K 350 and K 500 is supplied in the form of devices (lubricant tank, startup pump, oil cooler) and other elements (fittings, pipes, etc.). All devices are installed and connected to the system during the compressor installation. In TsTK 275/9, the lubrication system is made in the form of a factory assembled unit;
- Supplied with control systems devices and anti-surge protection;
- With state-of-the-art automatic control system (ACS).

Competitive advantages and design features:
- Coke oven gas exhausters are single-cylinder, two-stage, with one-side suction units;
- Case is made of cast iron, with horizontal and vertical splits;
- Suction and delivery nozzles are turned down. Two impellers fixed on a shaft, diffusers and guiding vanes form gas flow path. Labyrinth seals separate compression stages. Asynchronous motors are as a drive;
- Coke-oven gas exhausters are provided by shaft-turning gear;
- For rotation the rotor during oiling;
- When exhausters are in standby mode;
- During their steaming before start up and after shutt-down. Steaming process is carried out;
- For cleaning gas flow path from tarry substances.
