Coal Quality Monitoring and Control

Increase efficiencies & realize fuel cost savings with optimal coal blends

Coal is still used in most cement plants globally, to deliver the energy needed for the heat inside the kiln. Potential product solutions include the Thermo Scientific CQM FLEX Coal Analyzer and the Thermo Scientific ECA-3 Elemental CrossBelt Analyzer, both powered by PGNAA technology. These analyzers control coal blends to allow cement producers to mix low cost coals with higher costs coals to provide additional cost savings in fuel, and to allow a consistent feed to the kiln.  Our belt scale offerings and tramp metal detectors provide value in production and safety.

Products used in coal blending for coal power generation

Facilitate sorting, blending and out-of seam dilution control with the Thermo Scientific ECA-3 Elemental Crossbelt Analyzer. The ECA is a Prompt Gamma Neutron Activation (PGNAA) coal sampling unit designed to mount around an existing conveyor belt and analyze the composition of the total burden of coal on the belt in real-time.

Minimize variations in coal quality, ensure contract compliance, and improve efficiency with the Thermo Scientific CQM FLEX Coal Analyzer. The CQM FLEX is a full-featured coal quality analyzer that can incorporate either Prompt Gamma Neutron Activation (PGNAA) or Pulsed Fast Thermal Neutron Activation (PFTNA), and it provides the option of sourcing the neutrons from traditional Cf-252 radioactive sources or via an electrically driven neutron generator.

Blend up to six coal sources based on multiple quality parameters with the Thermo Scientific COBOS Coal Blend Optimization System. COBOS software continuously monitors coal quality for high quality coal blends while achieving more cost-effective, efficient operations.

Monitor raw material feed to crushers, mills, screens, preparation plants, and coal-fired power plants to help ensure precise feeding of process materials and maintain product quality. Thermo Scientific Ramsey conveyor belt scales provide vital information for the effective management and efficient operation of cement raw material handling.

Protect expensive crushers, conveyors and other process equipment from damage by tramp metal. Thermo Scientific Ramsey Oretronic IV Tramp Metal Detectors detect all types of metallic scrap that conventional metal detectors may miss.

PGNAA and PFTNA help ensure coal blends meet specifications

In the coal blending process, different quality coals are mixed to meet requirements for particular applications. Blending decisions impact the total amount of each product that a mine site is able to sell, so it is important that the blended coal meet quality specifications.

Online and At-Line elemental analyzers are used to measure the composition of coal in real-time and proactively address process variations to ensure more consistent coal blends. The analyzer mounts around an existing conveyor belt or adjacent to a main conveyor with an in-line coal sampling unit to continuously monitor coal quality. When combined with coal blending software these unique instruments offer the most effective way to minimize variations in coal quality, ensure contract compliance, and improve efficiency.

Online and At-Line coal analyzers utilize an analysis technique termed either Prompt Gamma Neutron Activation (PGNAA) or Pulsed Fast Thermal Neutron Activation (PFTNA) technology. These technologies are deeply penetrative and measure the entire material volume travelling by conveyor at a high frequency, making them ideal technologies to help ensure that all the coals in the supply mix are properly blended.

Our online elemental analyzers utilize a Neutron source and also generate Gamma rays as part of the analytical process. We offer radiation detection pagers to assess the possible radiation exposure and ensure that these stay within acceptable limits.
