SIEMENS says that its LDS6 laser gas analyser is proven to improve safety and save cost in damage repairs in the mining industry.

The LDS6 laser gas analyser did just this for the Tasmanian Electro Metallurgical Company (TEMCO), a subsidiary of BHP Billiton, by alerting its manganese ferroalloy plant workers to an imminent furnace explosion in time to prevent it.

According to Paul Dennis, Process Technology Supervisor, TEMCO, sudden explosions are known to arise in these furnaces due to the temperature control mechanism, which pumps water through a series of tubes inside the furnace to maintain the internal temperature. Over time, the water eventually erodes these steel tubes and this allows some water to leak into the furnace.

Trials undertaken by Dennis enabled a set of control limits to be established, with the analyser detecting water leaks hours before any other traditional methods have been able to.

The safety procedure developed around the Siemens analyser was a step towards achieving zero fatalities in the highly volatile and unpredictable environment around plant furnaces.
