Application examples
Excavation control in open-pit mine
The online analyzers installed directly on mining excavators can verify whether the actual coal quality agrees to expected parameters and adjust the excavation scenario accordingly. The resulting quality is measured on the main run-of-mine conveyors. Based on on-line measurement there can be determined the stockpiling strategy. The quality of stacked coal is monitored by the on-line analyzers on stacker/reclaimers. In reclaiming process the system can verify the resulting quality of coal delivery. The GE3000 series analyzers can be utilized in control of sorting flap-gates for immediate quality based redirection. In case of change in coal quality the flap-gate can redirect the good quality material to direct dispatching (e.g. export coal) but the reject coal can be diverted for separate storage. During coal dispatch the GE3000 series online analyzers monitor the coal quality in respect to customer requirements. The actual balance is monitored during outloading process. The overall batch quality can be corrected by addition of different quality coal in case of non-fulfilment of requirements.
Coal analysis in underground mines
The online analyzers are used for monitoring of coal quality coming from different mine sections for excavation control. The ATEX certified version of online analyzer can be placed directly in underground tunnels.
Coal analysis in power stations
For power plant coal feed control the GE3000 series online analyzers are installed on the inlet belt conveyors. Based on on-line measurement there can be determined the stockpiling strategy. The quality of stacked coal is monitored by the on-line analyzers on stacker/reclaimers. In reclaiming process the system can verify the resulting quality of feeding coal. Analyzers installed on plant feed conveyors monitor the coal quality before the feeding bunkers. The coal can be sorted to different bunkers based on quality parameters and consequently the whole quality range of input coal can be blended for optimized combustion.
Coal analysis in washing plants
The coal washeries can use the online analyzers directly for process control. There is measured not only input and output coal quality but also midlings in process of washing. The operator has all the quality information available in real time so that operative decisions can be taken immediately. The GE3000 series on-line analyzers installed at the cyclone or separator output monitor the parameters of wet coal. It is used for direct process control. In case of deviation from required parameters the system will automatically control the washing media to become thicker or thinner. To monitor the efficiency of washing processes there are also online monitored the parameters of rejects.
Transshipment and distribution
By help of GE3000 series on-line analyzers it is verified whether the quality of the coal is in line with declared parameters at the site input and also at the output just before outloading.
Special applications
- Installation on reject belt of coal sampler
- Measurement of unburned content in solid ash
- Measurement of quality of oil shales or other materials
- Measurement of coke and coking blends
Nuclear safety
The detection stage is designed with strong focus on maximum safety and reliability. The radionuclides are placed in easily transportable shielding container made of wolfram and stainless steel to ensure its endurance even in case of fire or other extraordinary situation. In inoperative position the shielding container allows safe transport and storage with no need of removal or manipulation with the radionuclides. By setting the container to working position the radiation beam is directed through the belt conveyor only while presence of personnel beside the belt conveyor is not limited.
GE 3030 in-service rapid coal analyzer
The GE 3030 allows quick determination of ash content in given coal samples directly on site, eventually in laboratories. This allows to taking operative decisions and significantly improve efficiency of operations and economy.
The content of non-combustibles is evaluated based on attenuation of gamma radiation of two different energies. The device is in desktop design. The complete measurement unit is integrated in single casing and the operator does not manipulate with the sample inside the radiation beam. Control and setup of the unit is performed using the touchscreen operator panel. The use of the unit is simple so that no special training is necessary for operators.
