Ash System

When coal is burned in the boilers, two types of ash are produced.

The heavier ash, which collects in the bottom of the boiler, is called "bottom ash". This ash is collected and trucked back to the mine site, where it is buried before the land is reclaimed.

The remaining, lighter ash, which is carried through the boiler with the exhaust gas, is known as "flyash". The flyash is removed from the furnace exhaust by electrostatic precipitators. With the flyash removed, the remaining flue gases are discharged up the stack.

Much of the collected flyash is sold to be used in the manufacture of concrete. The remaining flyash is returned to the mine for burial.

Hours of operation 2023

We are located on the grounds of the Leduc West Antique Museum. Travel 5 miles west of Leduc on Highway 39. Go north on Range Road 260 (Cohne Dale Road) for about 800 metres and the museum will be on your right. The LWAS Annual Exposition on July 22 & 23 was a great success and now we look forward to the Fall Harvest on September 9 & 10, with public tours, exhibits and the Tractor Pull Provincial Finals event. The final music performance of the season will feature “Celtera” and as their name implies is steeped in the music from the Emerald Isle and Scotland. Finally, on September 15 & 16, the Lesco Pro Truck Show n' Shine arrives at Leduc West. Although our museum will only be open on the 16th, please come out and see the trucks on both days!
