Fuel
The DVC500 is designed to burn Anthracite Rice
Coal, which is approximately 3/8" long and wide
by 3/16 thick. Anthracite coal is considered either
White Ash or Red Ash.
White Ash Coal will have 13 to 14,000 btu's per
lb. White ash coal usually has less ash and will burn
longer.
Red Ash coal is usually about 12,000 btu's per lb.
and is higher in volatiles. Higher volatiles makes the
coal easier to light and produces a more yellow ame.
At a very low burn rate the TCP (Temperature
Control Probe) may be activated with Red Ash coal,
especially if the hopper lid is open or leaking. The
TCP senses the temperature of the feeder and feeds
coal if the temperature rises too much. This prevents
the re from reaching the coal in the hopper. Red
Ash Coal may form klinkers (fused together ash)
which may cause grate blockage in severe cases.
Anthracite Coal can be purchased in bags or in bulk.
If you buy in bulk, try to have the coal delivered
before temperatures reach the freezing level. This is
because salt may be added to the coal to keep it from
freezing on the truck. This will not affect burning
but will promote rust and corrosion.
Some Coal Companies wash their coal better than
others to remove nes and dirt. This makes air ow
through the coal better and produces less y ash.
Whether bagged or in bulk, the coal must be dry
before loading it into the stove. At a minimum,
open bags a few days in advance to allow drying.
Buy your bulk coal mid summer to allow plenty of
time for drying.
Good, clean, White Ash Coal is the fuel of choice,
"however" Red Ash Coal will also burn well. As
long as it is Anthracite.
