It replaces an airtight
stove, which was causing problems for an occupant with chemical sensitivities.

Project
Outline
Complete Proposal
Objectives
1. To establish an accepted protocol for testing masonry and other wood-burning
devices.
2. To determine the emissions from an existing wood-burning masonry heater.
3. To determine the calculated burn efficiency of an existing wood-burning
masonry heater.
4. To determine most effective way to regulate the combustion air to
the heater
5. To compare emissions and efficiency between a masonry heater and (1)
a conventional fireplace and (2) a high efficiency manufactured wood burning
heater.
6. To determine viability of masonry heaters in Alaska.
Tasks
1a. Purchase and assemble test equipment.
1b. Consult with Omni Environmental Labs and Norbert Senf of The Masonry
Heater Association in Portland, Oregon to create the testing protocol.
1c. Base protocol on EPA and ATSM standards.
2a. Obtain cord wood with a 20% moisture content (white birch, spruce
and dimensional Douglas Fir for fuel crib construction)
2b. Separate the wood into ASTM calculated fuel cribs for the heater test.
2c. Fire the heater for 30 to 50 consecutive days for analysis.
2d. Measure O², CO, and CO2 and stack temperature starting at firing
and continuing
until completion of combustion.
2e. Collect and process samples to measure stack gas particulate (PM 2.5
and PM 10)
emissions.
3a. Calculate the energy efficiency of the heater using the weight and
moisture content of the wood, the emissions and stack gas temperature.
4a. Record burn time.
4b. Photograph flames.
4c. Record CO change with change in inlet air.
4d. Thermal image the exterior mass
5a. Obtain established emissions and efficiency data of a conventional
fireplace and of a high efficiency manufactured wood burning heater.
5b. Compare emissions and efficiency of a masonry heater with a conventional
fireplace and with a high efficiency manufactured wood burning heater.
6a. Determine viability based on quality of emissions, cost effectiveness
and performance.
6b. Determine cost-effective sources of local construction materials
