Regarding: Renewable Heat NY Program, Call for Qual ified Wood Pellet Boiler Technologies

Revised to remove statement about CBI.

To whom it may concern,

Tarm Biomass is submitting test data for the Frölin g P4 wood pellet boiler in sizes 8/15, 20/25, 32/38 , 48/60, and 80/100 kW (qualified wood pellet boiler technologies).

All test data is derived from European testing cond ucted by TUV using EN303-5 and converted by Tarm US A, Inc. and Fröling as follows:

For Converting CO from results at 13% O 2 to results at 7% O 2 :

a) using EN 303-5:2012 – chap. 5.10.4 Emission s: “These mean values of the volume parts (ppm) shall be used to calculate the mass values (mg/m3). For the rate of exchange from ppm to mg/m3, the followi ng values should be used:

• f

CO = 1,25“
 1 mg/m3 @ 13% O 2 / f CO = 0.8 ppm @ 13% O 2 E [ppm @ 13% O 2 ] = 0.8 x E [mg/m3 @ 13% O 2 ]

b) principle of dilution in dry exhaust gasses :

with
E, ref2 Emission rate referred to Oxygen concentration desired
E, ref1 Emission rate referred to Oxygen concentration given

O ref2 Oxygen concentration desired in %

O ref1 Oxygen concentration given in %

 E7 [ppm @ 7% O 2 ] = (21 – 7) / (21 – 13) x E13 [ppm @ 13% O 2 ] E7 [ppm @ 7% O 2 ] = 1.75 x E13 [ppm @ 13% O 2 ]

c) combined formula (dry exhaust gas at standa rd conditions):

E7 [ppm @ 7% O 2 ] = 1.75 x 0.8 x E [mg/m3 @ 13% O 2 ]
 E7 [ppm @ 7% O 2 ] = 1.4 x E [mg/m3 @ 13% O 2 ]www.tarmbiomass.com

4 Britton Lane ▪ P.O. Box 285 ▪ Lyme, NH 03768 ▪ 800.782.9927 For Converting Dust emissions to pounds of emission s/Million British Thermal Units:

Convert by unit analysis. Here is the conversion s et up:

21 mg g 1 lb 1 MJ 1,000,000 Btu =

MJ 1000

mg 454 g 948 Btu MMBtu

Cancel the units that you can and solve. You can d o this by first multiplying across the numerator an d then do the same for the denominator. Finally divide the numerator by the denominator.

Convert by unit analysis. Here is the conversion s et up:

21 mg g 1 lb 1 MJ 1,000,000 Btu = 0.049 lb/MMBtu

Tarm Biomass and its partners have made the require d calculations and attach them separately.

Please contact me directly if there are any questio ns or concerns about our data.
