Innovative measuring technology on the burner cutsoperating costs when using liquid substitute fuels

The cement production process requires large quantities of ­energy. For this reason, the use of secondary fuels was studied intensively at an early stage, with the aim of reducing energy costs in the thermal zone of this process. The most diverse substances, extending from coarse-particled (three-dimensional) solids up to and including liquids, are used, depending on their market availability and their suitability for the combustion process, to heat the rotary kiln.

A constant energy-input rate is important in clinker production, to assure consistent and uniform clinker quality in the kiln....
