### 1 DESCRIPTION

1.1 General

The tested pellet burner PELLEMATIC PE64 manufactur ed by ÖkoFEN Forschungs- und Entwicklungs Ges.m.b.H. with a nominal heat output of 64.0 kW comprises a storage container, a fuel feeding system with integrated fire protection valve, the burner including burner plate, the flam e pipe and the attached pipe heat exchanger with clea ning springs. The burner is equipped with electric ignition, an automatic cleaning system for the heat exchanger, a speed-controlled combustion fan, a draught fan and a microprocessor control system with associated switches and

sensors.

A sheet metal storage container was used to perform the tests. An extraction screw transports the fuel through the entry pipe with integrated burn-ba ck ball valve to the stoker screw. The stoker screw is driven by a gear motor and transports the fuel from below onto the heat-resistant steel burner plate. The fuel is ignited by an electric he ating cartridge. The burner is regulated by a syste m using a combustion fan, a draught fan, the boiler t emperature sensor and the combustion chamber temperature and pressure sensors to control the hea t output. A radial fan directs the combustion air as the primary air flow through the fuel and as a s econdary air flow to the fuel gas via a postcombustion ring in the flame pipe. The combustion g ases then exit the flame pipe and flow into the heat exchanger. The heat exchanger is automatically cleaned by internal cleaning springs actuated by a motor. The ash from the heat exchanger and bur ner is collected in an ash drawer below the burner plate. The combustion chamber and heat excha nger are thermally insulated from the

outside.

The ignition process is monitored by measuring the combustion chamber temperature. Once ignition has been successful, the control system sw itches to heating mode and controls the heat output level according to the required heat output. The fuel and combustion air quantities are preset for various heat output levels and then regulated d uring operation according to the boiler temperature and combustion chamber temperature.

### TESTS AND RESULTS

Measurements were taken to determine the heat outpu t, boiler efficiency (direct method), flue gas composition, flue gas temperature in the measuring section, feed pressure (draught), emission characteristics and electrical power consumption. T he surface temperatures were measured at nominal heat output and stationary operation; this allowed the surface losses to be estimated.

The measurement equipment and measurement method co rrespond to ÖNORM EN 303-5:1999, ÖNORM EN 304:2005 and EN 267:1999. The measurement accuracy and measurement uncertainty are stated in documented procedures for verification in the quality management manual issued by the Federal Institute of Agricultural Eng ineering (Bundesanstalt für Landtechnik).



### 2.1 Test setup – measurement methods

BOILER TEST RIG WITH HEAT EXCHANGER: Heat output measurement by directly measuring the amount of water circulated through the heating circuit and its temperature increase (DIN 4702- 2:1990).

FLUE GAS EXTRACTION through a vertical measuring section, generating th e feed pressure using a flue pipe, diameter 200 mm, height above gr ound level 9 m, feed pressure limited by draught limiting flap.

HEAT OUTPUT MEASUREMENT: Determining the mass flow using the Coriolis mass flow meter PROMASS 63 F from Endress & Hauser, as well as the water temperatures at the boiler flow/return using a Pt 100 resistance thermometer, 1/3 DIN, cal ibrated as a pair.

FLUE GAS TEMPERATURE in the measuring section using a measurement syste m with 5 Pt 100

resistance thermometers.

FEED PRESSURE: Differential pressure transducer (Delta-P P92K), me asurement range
0 – 100 Pa.

WATER-SIDE RESISTANCE: Differential pressure transducer with ceramic meas urement membranes, DELTABAR S PMD 70 from Endress & Hauser.

CARBON DIOXIDE AND CARBON MONOXIDE CONTENT: Non-dispersive infrared gas analyser NGA 2000 from Emerson; carbon dioxide: lowest measu rement range 0 – 5 %, highest measurement range 0 – 20 %; carbon monoxide: CO Low - lowest measurement range 0 – 50 ppm, highest measurement range 0 – 2500 ppm, CO High - lowest measurement range 0 – 1.0 %, highest measurement range 0 – 10 %; measured in dry flue gas.

DUST CONTENT: Measuring device for gravimetric determination of total dust by company Paul Gothe GmbH with nominal suction quantity of 6 m 3 /h, dust separation on stuffed quartz wool filter; filter is located directly after sampling probe and elbow, determination of partial flow volume by dry gas meter and upstream drying tower. Sampling point for determination of dust content is arranged directly after measuring section.

CONTENT OF ORGANIC GASEOUS SUBSTANCES: Flame ionisation detector from JUM, Type VE 5; samples taken via heated filter and heated pi pe (thermostatically controlled to 180 °C); measured in damp flue gas.

ELECTRICAL POWER CONSUMPTION Modular energy meter ULYS ETD from ENERDIS, threephase 100-400 with a measurement accuracy for activ e energy corresponding to IEC 61036/EN61036 Cl.1. Maximum resolution of the pulse output: 0.1 Wh.

Power Analyzer Norma 4000 with 3 Power Phase PP40 a nd following specifications: 8 measuring ranges for voltage (0.3 / 1 / 3 / 10 / 100 / 300 / 1,000 V), 6 measuring ranges for current (30 – 100 mA – 0.3 – 1 – 3 -10 A). Basic ac curacy amount to +/- 0.1 % of measured value and +/- 0.1 % of measuring range, sampling rate 341 kHz, bandwidth for voltage 3 MHz.

DATA LOGGING using TopMessage data logging system from Delphin Technologie AG, sampling interval 1 second, average value determined from 10 measurements, average data stored to media.



### 2.2 Performance of heating tests

HEAT OUTPUT: Measurements were carried out in accordance with Ö NORM EN 303-5:1999 at nominal and minimum heat output respectively ( ≤ 30 % of the nominal heat output). The nominal heat output measurements were performed after the b urner had been operated for at least 3 hours in the nominal heat output range. The measurements themselves were taken over a test period of at least 6 hours. The efficiency was calculated by taking into account the heat stored in the boiler

water.

EMISSIONS: Carbon dioxide, carbon monoxide, organic carbon an d nitrogen oxide values were averaged over the whole test duration. When determi ning the dust content, the extraction time per
filter was limited to 30 minutes. The dust content was determined from 6 half-hourly averages, evenly distributed over the test duration. Calibrat ion gases were used to check the gas analysers before and after every test period.

SETTINGS: The declared measurements relate to reproducible t ests using optimised settings. The settings were made during preliminary tests based o n manufacturer recommendations. The aim

was to maximise the carbon dioxide content whilst a t the same time minimising the carbon

monoxide content.

FUEL: The measurements were performed with wood pellets compliant to ÖNORM M 7135:2000,
having a diameter of 6 mm and a water content of 7. 9 % and 7.7 %. The water content, the ash content and gross calorific value were measured; th e average values for the basic chemical data relating to the water and ash-free substances as we ll as the calorific value were taken from ÖNORM M 7132:1998.

FUNCTION CHECK of the temperature controller, safety temperature limiter and monitor as well as a functional check to verify the rapid shutdown of the burner 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 calculat ing 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 and taking into account the pressur e and temperature.

The organic gas substances content was measured in the damp flue gas; the emissions were then converted for dry flue gas conditions and declared as organic carbon. The nitrogen oxide content was measured in the dry flue gas and declared as NO 2

### SUMMARY OF RESULTS

3.1 Heating tests

The PELLEMATIC PE64 pellet burner from ÖkoFEN Forsc hungs- und Entwicklungs Ges.m.b.H. with a nominal heat output of 64.0 kW, was tested i n the power range 18.5 kW – 67.0 kW using wood pellets compliant to ÖNORM M 7135:2000 having a diameter of 6 mm and a water content of

7.9 % and 7.7 %.

Since the boiler flue gas temperature is less than 160 K above room temperature at nominal heat output, the boiler manufacturer shall make recommen dations, in accordance with ÖNORM EN 303-5:1999, regarding the flue installation in o rder to ensure sufficient draught and to prevent sooting up of the chimney and condensation.Page 15 of 18

EN 303-5:1999. 3) Emission values in mg/m 3 (relating to 13 % O 2 , 1013 mbar, dry flue gas), corresponding to variou s domestic and international requirements.



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

the boiler

The functional check of the temperature controller and safety temperature limiter and monitor on the boiler was performed in accordance with section 5.13 of ÖNORM EN 303-5. The requirements

were fulfilled.



### 3.3 Function check to verify the rapid shutdown of the burner system

Since the tested PELLEMATIC PE64 pellet burner from ÖkoFEN Forschungs- und Entwicklungs Ges.m.b.H. is not equipped with a device to dissipa te the residual heat as described in section 4.1.5.11.3 of ÖNORM EN 303-5, the operating and fau lt conditions associated with a power outage

and sudden loss of heat extraction were simulated t o satisfy the definition of a burner system with a rapid shutdown facility.

No dangerous operating conditions arose with either the water system or the burner during the course of the checks on the temperature controller, safety temperature limiter and rapid shutdown facility.Page 16 of 18

Legal requirements relating to small burner systems

for biogenous fuels in Austria

Agreement according to Art. 15 a B-VG concerning an amendment to the agreement according to Art. 15 a B-VG relating to protective measures for small burners (1998)

Small solid fuel burners should not exceed the foll owing emission limits:

Emission limits [mg/MJ] Solid fuel burners CO NO

x OGC Dust

Biogenous fuels 1100 150*) 80 60 Manually

loaded Fossil fuels 1100 100 80 60

Biogenous fuels 500**) 150*) 40 60 Automatically

loaded Fossil fuels 500 100 40 40

*) The NOx limit only applies to wood burners. **) This limit value can be exceeded by 50 % during partial load operation at 30 % of nominal output.

Energy saving agreement according to Art. 15 a B-VG

The efficiency of small solid fuel burners should n ot fall below the following values:

Small burners used for solid fuel central heating:

Manually loaded

up to 10 kW 73 %

> 10 to 200 kW (65.3 + 7.7 log Pn) %

> 200 kW 83 %

Automatically loaded
