Data Sources Helpful in Assessing Emissions from Titan 2 Auger-fed Coal Boiler
OMNI Lab Space Heating Study Fairbanks Draft Report Rev 4
Tested at low: “Two tests were performed with this unit at the same heat output rate, which was approximately 35% of the maximum achievable heat output.” p 15
Moisture content of “wet stoker coal” 33.5%, p 15
Emissions gas by-products grams/hour table p 17; Titan 2 (#28 and #29) had highest emissions of sulfur and nitrogen oxides of 9 devices tested.
OMNI Lab Draft Appendix A PM2.5 Laboratory Results
Titan 2 tests #28 and #29, pp A22-A23: Hazardous Air Pollutant are very high – lead, selenium, chromium, cobalt, manganese, nickel, and arsenic
Not tested: mercury and beryllium
#2 Heating Oil Furnace #18, p A14
EPA Phase 2 Hydronic Heater Partner Agreement, p 5
EPA emissions limit standard = 18 grams per hour cap
Continuous feed models test procedure = “two runs for the maximum burn rate”
Sierra Research Critique of OMNI Space Heating Study
…”substantial emission reduction possible when using augerfed coal compared to a conventional coal stove or coal-fired hydronic heater” p 3
No comparison to oil furnace emissions that are more likely to be replaced. Used PM 2.5 grams/ton of fuel, not EPA emission limit standard which is g/hour. G/ton is not used to approve devices based on their emissions.
FNSB approval of Titan 2 coal boiler 1-24-2012 for OIT
Asserts unwritten “discretionary authority” not in FNSB Code Chapter 8.21.020 1.A.a.
Titan 2 email 05-10-2011 FNSB low burn rate
“Low burn” rate, not high burn rate, ordered by the Borough.
Plus, the Borough was asking for 2 more days worth of coal for Titan 2, “as there is not enough from the amount that we sent.” That coal never arrived.
Titan 2 email 2011-06-06 FNSB ambient temperatures
Dr. Jim Conner had concerns about OMNI performing the tests in a warm warehouse rather than at ambient winter temperatures that go below minus 40ºF. With coal of 33.5% moisture content, at colder temperatures ice feeds directly into the combustion chamber along with the coal. This cooling could increase the byproducts of incomplete combustion.

OIT/North Pole Coal’s “business plan” to sell a large number of Titan 2 coal boilers.

“The purpose of the test was to obtain certification by the Borough that this boiler met the air quality standards that apply to wood-fired boilers.” p 2
USGS report, Healy Coal Quality
“Usibelli mine coal contains high concentrations of lead and selenium and low concentrations of beryllium and mercury, all of which are designated as hazardous air pollutants (HAPs) by the 1990 Clean Air Act Amendment.”
