Heat Eye

The Heat Eye is a fully on-line instrument providing second-by-second measurement of the Ash, Moisture and Nett Calorific Value (Nett CV) ie the energy content of conveyed coal. This it produces in real-time rather than by the traditional method of laboratory analysis. This measurement is vital for decision making.

Heat Eye comprises an Ash Eye fully integrated with a moisture meter (e.g. Callidan MA500 or Berthold LB456 etc) The Heat Eye contains no Radioactive sources – it uses Natural Gamma and Microwave technology.

The new generation Heat Eye is fully modular. The basic Heat Eye is a conveyor mounted instrument providing real-time data to an existing computer control system. An optional Remote Display Unit is available for customers requiring a fully stand-alone system.
The Heat Eye is our latest development in world-class coal monitoring.


Heat Eye – benefits

  • In blending control systems the good use of the Heat Eye information enables suppliers to produce a more consistent product leading to higher financial proceeds. For example, this can be achieved by adjusting the ash content to counter uncontrolled changes in moisture to provide a product with a consistent Nett CV.
  • Enables a mine to adjust quickly and effectively the blend characteristics to meet the demands of customers requiring different Nett CV specifications.
  • In power station applications the Heat Eye information can be used to ensure the boilers are fed with fuel with a Nett CV falling within specification. This will ensure maximum boiler efficiency. In extreme cases, Low CV material can be diverted from the boilers, thereby reducing downtime and the associated costs.
