Significant upgrades were made to
the Walker Brothers Asphalt plant to
improve its performance. Hot oil
lines are used to maintain the
temperature of the asphalt cement
as it moves through the plant. The heater
that heats the oil was replaced with more
efficient equipment. Due to the effectiveness
of the new heater, 50% of the existing
hot oil lines were removed and 5 pumps
used to circulate the hot oil eliminated.
Fewer hot oil lines means less oil is required.
Insulation was also added to the new lines,
preventing heat loss and conserving energy.
Upgrades were also done to the burner on
the plant to improve its efficiency.
In 2014, the plant reduced its natural gas use by 14,067 m3, resulting in 103,332 kW of reduced energy.
