2390 Goldstream Road:
A Model 220 Coal Fired Boiler
Application:
The property this furnace is providing heat for is a 2 story, 8 unit
apartment building with 16 bedrooms. The boiler is also providing
domestic hot water for the property. This property required a
little over 5,000 gallons of heating oil per year, prior to conversion
to coal.
History:
This Model 220 was purchased in the fall of 2005, and transported to
Alaska in the back of a Dodge pickup. The preliminary work on the
gravel pad for the furnace room and an underground utilidor was done in
the late fall. Over the rest of the winter, whenever the weather
permitted, work proceeded on the furnace room. Although the room
wasn't done, by early April 2006, the oil fired furnace that was
heating the
property was failing, so we did the minimum required to get it
fired. So there remained a fair amount of work: the
coal bin is
far short of completion (including completely lacking a roof); the
boiler room needs to be finished and the
pipes connecting the buildings need to be properly insulated.
Work resumed on the bin and building in the summer of 2007. While the
concrete pad and back wall of the coal bin had been poured last summer,
the retaining wall was poured this summer. Then 60 yards of gravel was
laid to properly slope the ramp up to the bin for dumping the coal into
the bin. The temporary sloping sides in the bin were replaced with
permanant ones. Also the permant collection box (for clearing auger
jams) was installed. Half of the structural wiring in the furnace
room is now complete (including a lightswitch once it started getting
dark again in the fall!) Work still needs to be done insulating the
pipes and completing the roof.
