Summary On the 10

th of March 2014, Bureau Veritas Industrial Services has performed emission

measurements on a location from Fortum at Klaipeda, Lithuania. The objective of the emission measurements was to perform measurements to determine the concentration of dioxins & furans, in the flue gas of the power plant. The installation for the measurements is at a site of Fortum at Klaipeda. It is a new combined heat and power (CHP) plant. The installation is a waste- to power plant for waste and biomass with a capacity of approximately 50 MW heat and about 20 MW electricity. The measurements were performed in accordance with the European legislation EN ISO 17020 and EN 15259. The samples were analyzed according to EN ISO 17025. The specified standards for each component are described in chapter 2. In the table below the average measurement results are described. The Emission Limit Value (ELV) is derived from the European Guidelines for Industrial Emissions.

1. Introduction

On the 10

th of March 2014, Bureau Veritas Industrial Services has performed emission

measurements on a location from Fortum at Klaipeda, Lithuania. The objective of the emission measurements was to perform measurements to determine the concentration of dioxins & furans in the flue gas of the power plant. The installation for the measurements is at a site of Fortum at Klaipeda. It is a combined heat and power (CHP) plant. The installation is a waste- to power plant for waste and biomass with a capacity of approximately 50 MW heat and about 20 MW electricity The measurements were performed in accordance with the European legislation EN ISO 17020 and EN 15259. The specific standards for each component are described in chapter 2. The samples were analyzed in accordance with the European legislation En ISO 17025 by Eurofins Environment Germany. Bureau Veritas Industrial Services participants of the test: A. van Meekeren Project leader/Field engineer/ author B. Oudmaijer Field engineer emission measurements In chapter 2 and 3 a description of the measurement system and the measurement program is presented. In chapter 4 the results and the calculations of the tests are presented. The accuracy of the results is discussed in chapter 5.

2. Measuring and sampling equipment used by Bureau Veritas (SRM)

2.1 Contineous Measuring system Oxygen monitor operating according to the paramagnetic differential pressure principle, make: Emerson, type Rosemount MLT-3, inaccuracy ± 0,5% of the smallest measuring range (0-1% O2). The used range is 0 – 21 %. The analyzer is calibrated with an outside air of 20.94 vol.% O2.. The analysis of O2 is performed in accordance with EN 14789.

2.2 Discontinuous measuring system

Dioxins/ Furans The dioxins & furans sampling were performed using the so-called condensation method. Via a chilled glass measuring probe an isokinetic part stream from the waste gases was sucked through a XAD-2 cartridge. The concentration of 17 PCDDs and PCDFs is then determined in a laboratory through high resolution mass spectrometry gas chromatography. The sampling is conducted in accordance with EN 1948-1. A schematic representation of the sampling system is shown in appendix 1, figure 2. Flue gas flow The waste gas flow rate, pressure and the flue gas temperature is determined using redistricted calibrated measuring equipment. The water content is determined simultaneous with the wet-chemical sampling using the dry/wet bulb method. The sampling is conducted in accordance with ISO 10780, ISO 8756, EN 14790 and EN 13284-1.

5. Measuring uncertainty

In the presentation of the emission components which are sampled and analyzed several sources of errors can be determined which add up to the inaccuracy of the measurement. The measurement uncertainty indicates the uncertainty of a measured value. Each carried out measurement has a certain degree of uncertainty. Within the VKL (Dutch association of quality air measurements) a working method has been developed to determine the measurement uncertainties per component. At calculations it is assumed accumulation measurement uncertainties, reduced up to 1u absolute. Then the square root is taken of the sum of applied partial error sources. For the calculation of the total measurement uncertainty at 95% confidence interval it is multiplied there by two. The relative measurement uncertainty is calculated by the quotient of the absolute measurement uncertainty and the measured value. On the basis of a rack tool concerning performance characteristics of emission measurements, established by the VKL, an actual uncertainty has been calculated for each installation type. Besides the actual uncertainty a measurement must satisfy to put uncertainties according to applied standards and directives. See tables mentioned below for uncertainties. The measurement uncertainty is presented as 95% confidence interval. General data
