The ALS Coal site at Richlands in Brisbane has endeavoured to be energy smart by implementing and utilising the following energy conservation measures:

All internal Preparation Shed lights were changed from 400W bulbs to high efficiency 100W fluoro bulbs. Clear plastic skylights were installed to add free daylight light to the Prep Shed.

Open roof ridge capping and vented roller doors were installed to give better air circulation and a naturally cooler Prep Shed.

Where practical, extraction electric motors have been installed with variable speed drives so that the fume cupboard fans and float sink extraction fans can be successfully run at less than 50 Hz. This allows fewer kilowatts to be drawn by each electric motor but still allows suitable extraction. The extraction motors can also be fine-tuned to help minimise noise and the need for more air conditioned make up air in the Analytical Lab.

The new cold rooms inside the now cooler Prep Shed replace multiple refrigerated shipping containers that sat out in the sun at the previous site. These new cold rooms have extra thick, 150mm insulated walls and the access doors were fitted with plastic convection screens to further minimise the loss of cold air.

Richlands is also endeavouring to set up a large automated ash furnace that may allow the use of multiple smaller furnaces to be discontinued and potentially save further electrical energy costs.
