Boosting AF rates with flame thermography

06 November 2019, Published under Cement News

Over the past 30 years the cement industry has witnessed an increasing use of alternative fuels (AF), but the amount that can be fired in the main burner is limited by different process factors. To optimise AF firing in the main burner, VDZ has conducted several research projects with the aid of flame thermography. The know-how gained has been used to support producers seeking higher AF substitution rates, including a European plant that reached 100 per cent in the main burner without compro...

Enhancing kiln control

The major costs of clinker production are incurred in kiln pyro-processing, so it’s no surprise that this part of the process received more attention than any other. To-date, the trillions of tonnes of clinker manufactured have been produced in plants controlled mostly on elemental chemical data. Bogue equations construct hypothetical mineral compositions that ignore the heat treatment in the kiln.  Kiln control with COSMA on-line Mineral Analyser Fuel combustion specialist FCT...
