Automation System

HuDe Autostandpipe

The Autostandpipe is a system based on pneumatic operated stand pipe actuators, already existing on the battery or being upgraded by pneumatic piping and pneumatic cylinders suitable for the coke plant environmental conditions. The pneumatic cylinders are operated by electric impulse valves which need only an electrical impulse to be set in the required position. Thus, the position will be held also at power supply failure.
In case of automation fault, a hand lever allows manual switching. An automation system located in stainless steel cabinet operates the valves and provides the fibre optic interface to the HuDe control computer for standpipe automation, located at the battery control room nearby the coordination PLC (already existing) of the coke battery.
The coordination PLC gives the necessary information via Ethernet link to the HuDe computer. A standpipe automation control software will realise the automation process for standpipe operation on the battery. The charging cars are connected to the coordination PLC in order to synchronize the charging process with the Autostandpipe – System.

Positioning System

The HuDe HDC (HuDe Drive Control) system is designed for long travel control, oven identification and positioning of any type of coke oven service and operating machine working in coking plant surrounding under extremely high environmental temperatures.
The system supports unmanned operation for auto-positioning and redundant position identify permitted for cross battery interlocking. With features such as self-controlled function unit, automatic long travelling controlled by an integrated track calculator, the HDC systems also does validation check along with communication to the PLC over standard bus interfaces.
The HDC has certain functions: Rough positioning at long travel (by absolute encoder), fine positioning at oven (by light barrier system in reader head) and oven identification (by RFID tag in target plate and antennas in reader head).

Optimization of Oven Charging

HuDe coal charging systems guarantees a maximum individual oven chamber filling, short filling times and minimized opening periods. With high priority given to product optimization and emission protection, this system is used for the controlled optimization of the filling process of the oven chambers for top charging coke plants.

Control of Stamping device

All users of stamping machines need the patented HuDe Stamping Control System. It allows the online monitoring and controlling of all sequences of the process. The explosion-protected sensors are mounted at every stamp pusher. All sensors transmit their wireless data to the central data analysis unit.

Process automation and visualization

HuDe software for visualization (HMI human machine interface) allows a realistic reproduction of all sequences of processes. The softare presents detail processed information and has a clear representation, it supports the operating, the controlling and the maintenance activities of the operator.

Data Communication systems

HuDe data link and communication units are security oriented. The data link is based optional on the following two types of different transmission medium: glass fiber optic technology and HF data radio technology. A safety transmission medium combined with robust software protocol structures forms the stable backbone of the HuDe automation technology.

Wharf Coke detection Systems

The coke wharf is used to gather coke discharged by the Coke car. After a complete discharge, the coke is checked for glowing points which have to be quenched manually. The coke remains on the wharf for approximately a half hour. During this time, the coke can cool down and the wate steam can be volatilized. Thereafter, it can be transported to the screening plant where the coke is crushed, sorted and loaded.

The Coke wharf is subdivided into sections with each of them belonging to the discharging position with the capability to house wagon loads of coke. Each section is permanently monitored by three radar sensors respectively. The sensor provides the information if the subjacent monitored wharf section is empty or occupied.
