Jerry Frisch supplied the preliminary summary below of the recent emissions tests at OMNITEST Services.
Description of each group of bars:(from left to right)
Large group on left:
The "round robin" woodstove used by EPA to compare inter-laboratory repeatability. The PM numbers are shown in order of increasing burn rate.
- Note that this stove has very low emissions at its optimum burn rate, and high emissions both at low burn rates and at high burn rates.
- Note that results are shown for both the EPA fueling protocol and the Northern Sonoma (NSC) protocol.
Tall pair of bars:
A 36" zero clearance (metal) fireplace. It required the use of a grate, because it had a sheet metal floor.
Middle group of four bars:
Four masonry fireplaces burned with doors closed. The fireplaces are as follows:
- Fireplace "A" - "Western States Clay Products Assoc. (WSCPA)" fireplace designed by Jerry Frish - a standard fireplace with insulation between the firebricks and the facing.
- Fireplace "B" - "standard" masonry fireplace, burned with a grate
- Fireplace "C" - a 36" Rumford fireplace.
- Fireplace "D" - a Frisch Rosin fireplace developed at Lopez Labs
Rightmost group of four bars:
The same 4 fireplaces as above, burned with the doors open.
Comments from Jerry Frisch:
The metal fireplace and the "standard" masonry fireplace both used a grate, and had the highest emissions numbers.
