Glycol-based systems support hot and cold batch water lines, plus
lines to production beds carrying steam for curing. Included in the
mechanical scheme are two Boilerroom Equipment Inc. HeatSponge
units, which recover flue gas heat otherwise released. They contrib-
ute to heating system efficiency around 90 percent. The Sidekick
Water Boiler Economizer (center, w/recycling symbol label) is for
condensing and non-condensing. Pennsylvania-based Boilerroom
Equipment notes that the Sidekick can bring condensing efficiency
to conventional boilers.
The bins feed a skip hoist bucket sized to transfer the full ag-
gregate requirements for each batch loaded into the Voeller Cy-
clo-Mixer 1855VB, with 6-yd. mixing tank and 5-yd. output. The
three 350-bbl. silos have fill tubes bearing anti-overfill devices
that prevent vessel and baghouse damage. Batching operations,
plus aggregate receiving and heating functions, run on a Win-
dows-based Eagan KF Batch2 controls package.
