Scope 

The manufacturer orders the evaluation of ineasurements on flue gas emissions and 

efficiency. Basis for the evaluation are the results documented in the test report no. 

H-C4 1190-00/11 dated 2011-02-09. 

Basis of test 

DIN EN 303-5:1999-06 Heating boilers for solid fuels, hand and automatically 

stocked, nominal heat output of up to 300 kW, clause 4.2 

Test documentation 

Test report no. H-C4 1190-00/11 dated 2011-02-09 on the test of performance 

requirements of the heating boiler type BioWIN 350 Premium and BioWIN 350 Exklusiv 

4 Description 

The boilers were type-tested according to the requirements of DIN EN 303-5:1999-06 by 

the test laboratory for firing and heating technology of TOV SOD Industrie Service GmbH. 

A detailed description of the boilers and the test for boiler performance are documented in 

test report no. H-C4 1190-00/11. In the type test a measurement was included for CO, 

unburnt hydrocarbons, dust emission and efficiency.

5 Measurement and analysis methods 

5.1 COZ / CO measurement 

For the CO2 / CO measurement a calibrated device on the principle infrared absorption 

was used. The values are measured continuously during the complete test period. The 

mean values for CO2 / CO are 

- 13.3 % / 39 ppm (maximum load) 

9.1 % / 63 ppm (minimum Ioad) 

5.2 Unburnt Hydrocarbons 

For the measurement of unburnt hydrocarbons a calibrated device on the principle of 

flame ionisation detection (FID) was used. The calibration was performed on the basis of 

propane (C3 1-1 $). The values for unburnt hydrocarbons are measured continuously during 

the complete test period. The mean values for unburnt hydrocarbons are 

1 ppm (maximum load) 

1 ppm (minimum load) 

5.3 Particulate emission (dust) 

For the measurement of the particulate emission (dust) a calibrated filter instrument and a 

calibrated balance were used in a gravimetric procedure according to CEN/TS 15883, 

annex A. The dust emission was measured 4 times in the test period. Each period of 

measurement takes 30 minutes with a constant volume of the sample. The mean values 

for dust emission are 

21 mg/ma (maximum load, related to standard reference conditions) 

12 mg/m3 (minimum Ioad, related to standard reference conditions) 

5.4 Efficiency 

The test was performed by TOV SOD Industrie Service GmbH using a test rig according to 

picture A.2 of EN 304:2004-01. The values are measured continuously during the 

complete test period. The mean values for direct efficiency are 

- 91.2 % (maximum Ioad) 

88.8 % (minimum load)

Summary 

The emissions and efficiency as documented in report no. H-C4 1190-00/11 are measured 

in line with EN 303-5 regarding the determination of inorganic and organic 

gaseous or particulate air constituents, 

using existing procedures in the quality system of the laboratory for firing and 

heating technology and 

using calibrated measurement devices. 

The calculation of the measured emissions data with reference to 10 % 0 2 and on the 

measured data on efficiency as required by EN 303-5 is documented in the test report 

no. H-C4 1190-00/11.
