Abstract

A system is provided for collecting and analysing data relating to an operating condition in a top-submerged lancing injector reactor system having a lance, the lower end of which is to be submerged in a molten bath during operation of the top- submerged lancing injector reactor system. The system includes: (a) at least two sensors configured to sense an indicator of the operating condition and to generate a sensed data signal, each sensor being of a different sensor type and at least one of the at least two sensors being a lance-based sensor; and (b) a central processing unit for receiving a plurality of sensed data signals and analysing the sensed data signals relating to at least two indicators of the operating condition to determine a current status of the operating condition.
