Quick-setting cement manufacturer Lafarge Aluminates, based at Fos-sur-Mer, near Marseilles, has optimised fuel efficiency, improved process control and reduced plant downtime with a Servomex gas analysis system fitted to one of its two furnaces.

The plant produces cement from bauxite and adds aluminium oxide to give the material refractory qualities and corrosion resistance. It also produces special quick-setting cements for rapid runway and road repairs.

One problem which Servomex engineers had to overcome was that of the hostile environment in which the analysers would have to operate. The probe has to be located close to the burners in the furnace, and this could cause a potential blockage.

The system is based around a Servomex 1100 oxygen analyser, a Xendow 2500 measuring concentrations of nitric oxide and a 2510 measuring carbon monoxide, plus a sample conditioning system which cleans and dries the gas sample before it is presented to the analysers.

Data from the analysers enables the process control computer to optimise the use of fuel, minimising fuel costs.
