### 1 DESCRIPTION

1.1 General

The tested pellet burner EVOTHERM P 100 ECO manufactured by Evoth erm Heiztechnik Ve rtriebs GmbH with a nominal heat output of 105,0 kW comprises a boiler with integrated combu stion chamber and a vertically arranged three

- pipe heat exchanger, a fuel feeding system with int egrated burn

- back protection device and the stoke r screw. The burner is equipped with an electric

ignition fan, an automatic cleaning system for the heat exchanger, a speed

- controlled draught fan

and combustion fan, a Lambda sensor, a SPS

- system with control panel and the display with a ssociated switches and sensors.

A cuboid sheet metal storage container was used to perform the tests. The screw conveyor for the

fuel extraction is directly driven by a gear motor and transports the pellets to the downpipe with i ntegrated burn

- back flap. The stoker screw t ransports the fuel on the front side from below to the

combustion chamber with movable step grate. A firebed sensor is controlling constant supplies.

The combustion chamber is automatically cleaned from the ashes via a vertical shaft on the back

of the ste p grate.

The speed

- controlled combustion fans direct the combustion air as primary air flow through the

fuel bed and as secondary air flow to the fuel gases. The hot fuel gases pass through the aut omatically cleaned three

- pipe heat exchanger and release t heir heat. At the outlet of the heat e xchanger the speed

- controlled draught fan, the Lambda sensor and the flue gas sensor are i nstalled. The fuel is automatically ignited with a hot air blower. Below the combustion chamber the

ash container is sit u ated wh ich is automatically drained off. An electric control system ensures the

automatic operation of the system. Once the system has been switched on, the fuel is conveyed to

the combustion chamber and then ignited with an electric ignition. The optimal boiler temperature

is monitored by the control system. For optimizing the heat transfer the fuel volume, the primary

air and secondary air flow are regulated by the control system via a firebed sensor, the Lambda

sensor and the te m perature sensor.

The combustion chamber and the heat exchanger are thermally insulated from the outside.

### 2 TEST AND RESULTS

Measurements were taken to determine the heat output, boiler efficiency (direct method), flue gas

composition, flue gas te mperature in the measuring section, feed pressure (draught), emission

characteristics and the electrical power consumption. The surface te m peratures were measured at

nominal heat output and at stationary operation; this allowed the surface losses to be est imated.

The measurement equipment and the measurement methods correspond to ÖNORM EN 303

- 5:1999, ÖNORM EN 304:2005 and EN 267:1999. The measurement accuracy and the measur ement uncertainty are stated in the procedures for verification in the quality manag ement manual

i s sued by the Federal Institute of Agricultural Engineering (Bundesanstalt für Landtechnik).

### 2.2 Performance of heating tests

HEAT OUTPUT: The measurements were carried out in accordance with ÖNORM EN 303

- 5:1999

at nominal an d minimum heat output ( < 30 % of the nominal heat output) respectively. The nom inal heat output measurements were performed after the burner had been in operation for at least 3

hours in the nominal heat output range. The measurements themselves were taken over a test p eriod of at least 6 hours. The efficiency was calculated by taking into account the heat stored in the

boiler water.

GASEOUS EMISSIONS: Carbon dioxide, carbon monoxide, organic carbon and nitrogen oxide

va l ues were averaged over the whole te st duration.

DUST CONTENT: For determining the dust content, basically according to ÖNORM EN 13284

- 1:2002, the extraction time per filter was limited to 30 minutes. The dust content was determined

by 6 half

- hourly averages, evenly distributed over the te st duration. Calibration gases were used to

check the gas analysers before and a f ter every test period.

SETTINGS: The declared measurements relate to reproducible tests using optimised settings. The

settings were made during preliminary tests based on rec ommendations of the manufacturer. It

was aspired to maximise the carbon dioxide content whilst at the same time minimising the carbon

monoxide content.

FUEL: The measurements were performed with wood pellets according to ÖNORM M 7135:2000

with a diameter of 6 mm and a water content of 6,8 % and 6 ,9 % . The water content, the ash co ntent and the calorific value were determined; the average values of the chemical data relating to

the water

- and ash

- free su b stance were taken from ÖNORM M 7132:1998.

FUNCTION CHECK of the temperature controller, safety temperature limiter and monitor and the

installation to verify the rapid shutdown of the system . The measurements were performed as specified in 5.13 and 5.14 of ÖNORM EN 303

- 5:1999.



### 2.3 Interpretation of emission measurements

The emission measurements were analysed by calculating the complete flue gas analysis using

the carbon monoxide and carbon dioxide content averaged over the measurement period together

with the fuel composition data. The speed of the flue ga s at the measuring point was calculated

from the flue gas volume taking into account the pressure and temperature.

The content of organic gaseous substances was measured in damp flue gas; the emissions were

then converted for dry flue gas conditions and d eclared as organic carbon. The content of nitrogen

oxides was measured in dry flue gas and declared as NO 2

### 2.6 Surface losses

The heat loss through the boiler surface is determined using DIN 4702

- 2:1990 basing on radiation

coefficients and arrangements of technical surfaces (according to Nusselt). Temperatures were

measured at 58 points on the boiler surface during the test at nominal heat output. The mea sur ement results are shown in the following table and the table of measurements in appendix 5.2:

### 3 SUMMARY OF RESULTS

3.1 He ating tests

The tested EVOTHERM P 100 ECO pellet burner from the company Evotherm Heiztechnik Ve rtriebs GmbH , with a nominal heat out put of 105 ,0 kW, was tested in the power range of 30,0 to

105,0 kW using wood pellets compliant to ÖNORM M 7135:2000 having a diameter of 6 mm and

a water co n tent of 6,8 % and 6,9 %.

Since the boiler flue gas temperature is less than 160 K above room temperature at nomina l heat output, the boiler manufacturer shall make recommendations in accordance with ÖNORM EN 303

-

5 :1999 regarding the flue installation in order to ensure sufficient draught and to prevent sooting

up of the chimney and condensation.Pag e 15 of 18

### 3.2 Function check of the temperature controller / safety temperature limiter on

the boiler

The functional check of the temperature controller and the safety temperature limiter and monitor on the boiler was performed in accordance with section 5.13 of ÖNORM EN 303

- 5 :1999. The r equirements were fulfilled.



### 3.3 Fun ction check to verify the rapid shutdown of the system

Since t he tested pellet burner EVOTHERM P 100 ECO from the company Evotherm Heiztechnik

Vertriebs GmbH is not equipped with a device to dissipate the residual heat as described in se ction 4.1.5.11.3 of ÖNORM EN 303

- 5 :1999 , the operating and fault conditions assoc iated with a

power outage and sudden loss of heat extraction were simulated in order to satisfy the definition of

a burner system with a rapid shutdown faci l ity.

During the course of the checks on the temperature controller, the safety temperature limiter and

the rapid shutdown facility no dangerous operating conditions arose neither with the water system

nor the burner.Pag e 16 of 18
