### 1 DESCRIPTION

1.1 General

The tested pellet heating boiler EVOTHERM P 200 ECO manufactured by Evotherm Heiztechnik Vertriebs GmbH with a nominal heat output of 200,0 kW comprises a boiler with integrated combustion chamber and a vertically arranged three- pipe heat exchanger, a fuel feeding system with integrated burn-back protection device and the stoker screw. The burner is equipped with an electric ignition fan, an automatic cleaning sys tem for the heat exchanger, a speed-controlled draught fan as well as a secondary air fan, a Lambd a sensor, a microprocessor control system with control panel and the display with associated switches and sensors.

A 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 t ransports the pellets to the down pipe with integrated rotary valve. The stoker screw transports th e fuel upwards from where it falls through a drop shaft and a down pipe on the boiler front side which is equipped with a photocell and an inspection glass. From there it can fall into the hea t resistant metal burner. The boiler is periodically cleaned from the ashes by moving the step gra te; the residues fall then into the subjacent ash screw. A photocell is controlling constant sup plies. After reversing the combustion gases above the burn er, the gases are directed through the three-pipe heat exchanger. The speed-controlled com bustion fan directs the combustion air as primary air flow through the fuel bed and as second ary air flow to the fuel gases. At the outlet of the heat exchanger the speed-controlled draught fan , the Lambda sensor and the flue gas temperature sensor are installed. The burner and the heat exchanger are automatically cleaned by a separate motor which also opens the burner and cleans the heat exchanger pipe s with rotators. The ash finally falls into an ash screw which is installed below the heat exchang er and transports the residues into an attached ash box. The fuel is automatically ignited with a hot air bl ower. The combustion is monitored by a photo cell. It is then regulated by a Lambda sensor, a sp eed-controlled draught fan and a speedcontrolled secondary air fan according to the requi red heat output level. The negative pressure in the combustion chamber is monitored by a load ce ll. The combustion chamber and the heat exchanger are t hermally insulated from the outside.

BLT reference number: 027/07 

### 1.3 Diagram of the boiler

1 The draught fan produces the required low pressure which is measured and monitored by a low pressure device.

2 The flue gases flow through the three-pipe heat exchanger and release the heat to thecold water together with the cleaning turbulators.

3 The burner screw transports the pellets upwards which then fall downwards via a chute with integrated inspection glass into the combustion chamber. The fuel is ignited with a hot air blower. Above the inspection glass a photo cell is installed which controls

the flame.

4 The ash is transported to the ash screw by opening the ash removal element below the

2 nd and 3 rd draught.

5 The step grate arranges the cleaning of the grate by moving the grate elements. Thus the residues are directly transported to the ash screw.

6 The secondary air flow is led by a high pressure secondary air fan through the vent to the thermal reheating. The regulation is adapted according to the boiler output and the lambda value.

### 2 TEST AND RESULTS

Measurements were taken to determine the heat outpu t, boiler efficiency (direct method), flue gas composition, flue gas temperature in the measur ing section, feed pressure (draught), emission characteristics and the electrical power consu mption. The surface temperatures were measured at nominal heat output and at stationary o peration; this allowed the surface losses to

be estimated.

### 2.2 Performance of heating tests

HEAT OUTPUT: The measurements were carried out in accordance wit h ÖNORM

EN 303-5:1999 at nominal and minimum heat output (< 30 % of the nominal heat output) respectively. The nominal heat output measurements we re 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 period 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 values were averaged over the whole test duration.

DUST CONTENT: For determining the dust content, basically accord ing 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 distri buted over the test duration. Calibration gases were used to check the gas analysers before and aft er every test period.

SETTINGS: The declared measurements relate to reproducible t ests using optimised settings. The settings were made during preliminary tests bas ed on recommendations of the manufacturer. It was aspired to maximise the carbon dioxid e 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 con tent of 6,0 % and 6,1 %. The water content, the ash content and the calorific value were determined; the average values of the chemical data relating to the water- and ash-free substa nce were taken from ÖNORM M 7132:1998.

FUNCTION CHECK of the temperature controller, safety temperature l imiter and monitor, and

the installation to extract excessive heat of the b oiler. 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 aver aged over the measurement period together with the fuel composition data. The speed of the flue gas at the measuring point was calculated from the flue gas volume taking into accoun t the pressure and temperature.

The content of organic gaseous substances was measu red in damp flue gas; the emissions were then converted for dry flue gas conditions and declared as organic carbon. The content of nitrogen oxides was measured in dry flue gas and de clared as NO 2

### 3 SUMMARY OF RESULTS

3.1 Heating tests

The tested pellet heating boiler EVOTHERM P 200 ECO from the company Evotherm Heiztechnik Vertriebs GmbH, with a nominal heat output of 2 00,0 kW, was tested in the power range of 51,6 to 204,9 kW using wood pellets compliant to ÖN ORM M 7135:2000 having a diameter of
6 mm and a water content of 6,0 % and 6,1 %.

Since the boiler flue gas temperature is less than 160 K above room temperature at nominal heat output, the boiler manufacturer shall make rec ommendations in accordance with ÖNORM
EN 303-5:1999 regarding the flue installation in or der to ensure sufficient draught and to prevent sooting up of the chimney and condensation.Page 15 of 19
