Ii.b(2) Deviation From Standard Method - Drolet DB03105 Installation And Operation Manual

Report prepared for: Guillaume Thibodeau-Fortin (Stove Builder International Inc.) on 12/1/2017 8:00:00 AM
Test report #103124842MTL-001 (6 of 15)
Stove Builder International Inc.
Project No. G103124842
stoves, the test was conducted in accordance with WK47329-14 - Standard Test Method
for Determining Particulate Matter Emissions from Wood Heaters using Cordwood Test
Fuel. The fuel used for the test run was cordwood.
The applicable EPA regulatory limits are:
Step 1 – 2015 – 4.50 grams per hour.
Step 2 – 2020 – 2.50 grams per hour.
II.B(2)•Deviation•from•Standard•Method••
The following were modified from initial version of the standards utilized for this test program:
Changes to ASTM WK47329-14 are:
1- The wood heater must be aged for 50 hours.
2- The end of test criteria is defined when the weight scale indicates the remaining weight of
the test fuel as 0.0 lbs or less for 30 seconds.
3- Section 9.5.1 START-UP CONDITION. The heater surface temperature per 9.2.2 and flue-gas
temperature per 9.2.4 at the start of the test run must be less than a 10degF above ambient
for the high fire test category.
4- Section 9.6.14 invalid test run. The test run shall be considered invalid if less than the full
test fuel weight has been consumed and there is no measurable weight loss or 1% of the
test fuel weight, whichever is greater for at least 30 minutes.
5- Coal bed condition prior to loading test fuel. The coal bed should be at a level plane without
valleys or ridges for all test runs in the high fire, low and medium burn rate categories.
6- The pre burn cycle burn rate category, leading into a test run, should be the same as the
attempted burn rate category of the actual test.
Changes to ASTEM E2515-11 must be as followed:
1- The filter temperature must be maintained between 80 and 90 Degrees F during testing.
2- A glass cyclone must be used between the sampling probe and filter holders when the total
particulate catch is expected to exceed 100mg or when water droplets are present in the
stack gas. This cyclone and its contents must be included in the pre-test weighting and post-
test desiccation and weighing.
3- Filters must be weighed in pairs to reduce weighing error propagation.
4- Sample filters mu;ste be Pall TX-40 or equivalent Teflon coated glass fiber and of 47 mm,
100mm of 110mm.
5- Only one point allowed outside the +/- 10% proportionality range per test ruin.
