INTRODUCTION 

Page 4 of 18 

From May 13-31, 2005 lntertek Testing Services NA Inc. (lntertek) conducted tests on 

the Brian (code name for unit) outdoor boiler to determine emission and efficiency 

results for HPBA. The results to be used to help determine testing procedures for the 

proposed protocol test method. ' 

Tests were conducted by Bill Keen and Brian Ziegler. The tests were conducted at the 

lntertek Testing Services NA Inc. laboratory located at 8431 Murphy Drive, Middleton, 

Wisconsin. The laboratory elevation is 860 feet above sea level. Tests were evaluated 

to the Proposed Test Protocol for Outdoor Boiler Efficiency and Emissions Research 

Testing created by Rick Curkeet, Chief Engineer Building Products, lntertek. 

I. B. TEST UNIT DESCRIPTION 

The unit code named Brian is an· outdoor boiler. Further description is withheld to 

not allow identification. 

I.C. RESULTS 

The unit as tested produced an adjusted average emissions rate for oak 4x4 pieces of 

68.87 grams/hour and an average emissions rate for cordwood of 44.27 grams/hour. 

J.D. PRETEST INFORMATION 

The test unit was received at lntertek Testing Services NA Inc. in Middleton, 

Wisconsin on April 25, 2005. The unit was inspected upon receipt and found to be in 

good condition. The unit was set up following the manufacturer's instructions 

without difficulty. Following assembly, the unit was placed on the test stand and 

instrumented with thermocouples in the specified locations. 

The chimney system and laboratory dilution tunnel was cleaned using standard wire 

brush chimney cleaning equipment. 

On May 12, 2005, the unit was ready for testing.

III.B. UNIT DIMENSIONS 

Suppressed for identification security. 

III.C. AIR SUPPLY SYSTEM 

Combustion air enters the unit at the lower rear of the unit aided by a combustion air 

blower. Combustion air is controlled by an aquastat, which in turn starts the 

combustion blower and operates a solenoid that opens an air damper. This air is 

directed under the coal bed as under fire air. Combustion products then exit the unit 

through a eight-inch flue collar located at the top of the unit. 

III.D. OPERATION DURING TEST 

The water-to-water heat exchaf!ger was adjusted for each of the heat loads by 

increasing or decreasing the water flow through the cooling side of the heat 

exchanger. The inlet and outlet cooling water temperatures were monitored along 

with the Delta-T.

III.E. START-UP OPERATION 

Report Date: May 31, 2005 

Model: Brian 

Page 9 of 18 

Each test was started with a clean firebox and the scale zeroed. A fire was started 

using scrap wood. Once the unit had cycled at least twice, the firebox was cleaned 

out and the scale rezeroed. Coals were then returned to the firebox along with 

enough wood to have at least 2 cycles before starting the test. During the pretest 

loads, the water flow was adjusted to establish target heat draw. When the unit met 

the coal bed requirements; the scale.was rezeroed, test load inserted and the 

sampling system was started and was operated for the duration of the test run. 

IV. SAMPLING SYSTEMS 

The EPA Method 5-G3 sampling procedure was used. 

IV.A. SAMPLING LOCATIONS 

Particulate samples are collected from the dilution tunnel at a point 16 feet from the 

tunnel entrance. The tunnel has two elbows ahead of the sampling section. (See 

Figure 3.) The sampling section is a continuous 14"foot section of 12-inch diameter 

pipe straight over its entire length." Tunnel velocity pressure is determined by a 

standard Pitot tube located 96 inches from the beginning of the sampling section. The 

dry bulb thermocouple is located six inches downstream from the Pitot tube. Tunnel 

samplers are located 36 inches downstream of the Pitot tube and 36 inches upstream 

from the end of this section. (See Figure 1~)-

Stack. gas samples are collected from the steel chimney section 8 feet ± 6 inches 

above the scale platform. (See Figure 2.)

SAMPLING METHODS 

PARTICULATE SAMPLING 

Page 17 of 18 

Particulates were sampled in accordance with EPA Method 5G-3. This method uses 

two identical sampling systems with Millipore 47-mm diameter glass fiber filters. The 

dryers used in the sample systems are filled' with uDrierite" before each test run. ' 

V.B. EFFICIENCY 

Efficiency is reported in % of input energy delivered to the heated space and is 

denoted as rroelivered Heating Efficiency". 

VI. QUALITY ASSURANCE 

VI.A. INSTRUMENT CALIBRATION 

VI.A. (1 ). STACK SAMPLE ROTAMETER 

The stack sample rotameter is checked by running three tests at each flow rate used 

during the test program. The flow rate is checked by running the rotameter in series 

with one of the dry gas meters for 10 minutes with the rotameter at a constant 

setting. The dry gas meter volume measured is then corrected to standard 

temperature and pressure conditions. The flow rate determined is then used to 

calculate actual sampled volumes. 

VI.A. (2). GAS ANALYZERS 

The continuous analyzers are zeroed and spanned before each test with appropriate 

gases. A mid-scale multi-component calibration gas is then analyzed (values are 

recorded). At the conclusion of a test, the instruments are checked again with zero, 

span and calibration gases (values are recorded only). The drift in each meter is then 

calculated and must not exceed 5% of the scale used for the test. 

At the conclusion of each unit test program, a five-point calibration check is made. 

This calibration check must meet accuracy requirements of the applicable standards. 

Consistent deviations between analyzer readings and calibration gas concentrations 

are used to correct data before computer processing. Data is also corrected for 

interferences as prescribed by the instrument manufacturers instructions. 

Calibration gases are checked by ORSAT analysis when received to verify suppliers 

analysis.

TEST METHOD PROCEDURES 

LEAK CHECK PROCEDURES 

Page 18 of 18 

Before and after each test, each sample train is tested for leaks. Leakage rates are 

measured and must not exceed 0.02 CFM or 4% of the sampling rate. Leak checks are 

performed checking the entire sampling train, not just the dry gas meters. Pre-test 

·and post-test leak checks are conducted with a vac;uum of 10 inches of mercury. 

Vacuum is monitored during each test and the highest vacuum reached is then used 

for the post test vacuum value. If leakage limits are not met, the test run is 

rejected. During, these tests the vacuum was typically less than 2 inches of mercury. 

Thus, leakage rates reported are expected to be much higher than actual leakage 

during the tests. 

VI.B.(2). TUNNEL VELOCITY /FLOW MEASUREMENT 

The tunnel velocity is calculated from a center point pitot tube signal multiplied by 

an adjustment factor. This factor is determined by a traverse of the tunnel as 

prescribed in EPA Method 1. Final tunnel velocities and flow rates are calculated 

from EPA Method 2, Equation 6. 9 and 6.10. (Tunnel cross sectional area is the 

average from both lines of traverse.) 

Pitot tubes are cleaned before each test and leak checks are conducted after each 

test.
