Advanced kiln and cooler control
Practices such as over-burning clinker, the introduction of alternative fuels and ensuring cooler efficiency and reliability require reliable and consistent process control, as does the drive to reduce stack emissions such as CO2 and NOx. By John Window and Victoria Martin, Mirion Technologies, UK.
Despite concerns relating to cement production overcapacity (principally in Asia), it is forecast that the global cement industry will continue to grow at a CAGR of up to seven per cent until 2020.
Increased fuel costs, environmental factors and the drive to achieve the highest product quality is once more focussing on the need for reliable and consistent process control, whether achieved by providing manual plant operators with accurate real-time data, or automatically as part of a closed-loop or ‘expert’ control system.
