REPORT SUMMARY

In order to meet the requirements of the South African Air Quality Act No. 39 of 2004

(Reference 9.1), all Solid Fuel Combustion Installations (Category 1.1) such as Kendal Power

Station, are obligated to monitor several listed pollutants during operation. These pollutants

include particulate matter, Sulphur Dioxide and Oxides of Nitrogen. The Act further implies

that all emission programs are required to meet international standards such as EN 14181

(Reference 9.2) and EN 15259 (Reference 9.3). To this end, and in keeping with the ESKOM

Standard for Emission Monitoring and reporting 240-56242363 (Reference 9.4), ESKOM

scheduled a series of emission measurements on Units No. 1, 2 & 5 at Kendal Power Station.

The emission measurements were scheduled to be conducted in parallel with the permanently

installed Automated Measuring System or AMS on these Units. The data collated during the

parallel measurements was to be used in determining an AMS calibration function, calibration

range and operational variability as required by EN 14181.

Most Automated Measuring Systems or AMS require calibration to known quantity in order to

ensure accurate measurements. It is however not sufficient to use simulated reference material

alone to determine a calibration function for a gaseous emission AMS as the reference material

cannot replicate the complex and dynamic gas matrix present in an open operational system. It

is therefore necessary to determine a calibration function for each individual plant from the

actual conditions present using a parallel Standard Reference Method or SRM such as is

described in EN 14181. Such procedures must be conducted over a range of operating

conditions representative of a plant’s general conditions and typically consist of a series of 12

to 15 individual measurements.

The emission AMS instruments installed on Units No. 1, 2 & 5 at Kendal Power Station were

supplied and installed by Sick Automation. AMS’s with the capability of monitoring Sulphur

Dioxide, Oxides of Nitrogen, Carbon Dioxide, Oxygen, moisture, gas velocity, temperature and

gas pressure were included.

Stacklabs, an environmental testing laboratory, was contracted to complete the required

stratification & parallel measurements and to determine the calibration functions as described in

the EN 14181 standard. All the required site measurements were carried out during the period

from 23rd

of November 2016 to 10th February 2017. All the relevant results and calibration

functions have been presented in this report and may be summarised as presented in the

following pages:

1. Monitoring Objective

The primary objective of the emission measurements was to provide sufficient data to

determine the Automated Measuring System’s or AMS’s calibration function, valid calibration

range and determine the variability of the AMS in accordance with EN 14181 & EN 15259.

The requirement for conducting the emission measurements is to demonstrate compliance with

the requirements of the National Environmental Management: Air Quality Act (39/2004),

Listed Activities and Associated Minimum Emission Standards in terms of Section 21,

Category 1.1 to demonstrate compliance with the requirements of the ESKOM Standard for

Emissions Monitoring and Reporting, 240-56242363. The substances applicable under

Category 1.1 are Oxides of Nitrogen & Sulphur Dioxide which have been capped at 1100 and

3500 mg/Nm3 dry @ 10% O2 respectively.

In addition, the measurements are to demonstrate the Stations compliance with the

requirements of the ESKOM Standard for Emissions Monitoring and Reporting, 240-56242363.

Here the substances applicable under Section 3.8 are Oxides of Nitrogen, Sulphur Dioxide, and

Carbon Dioxide which have been capped at 1100 and 3500, & 315632 mg/Nm3 dry @ 10% O2

respectively.

2. Plant Description & General Operating Procedure

The pulverised fuel steam generating boilers on which the parallel measurements were

conducted were originally designed for a maximum steam flow equivalent to 697 MW. These

boilers were each equipped with two parallel electrostatic precipitators with a design capacity

of 1070 Am3/s gas flow and a performance collecting efficiency of greater than 99.93%. The

electrostatic precipitators were later retro-fitted with sulphur trioxide flue gas conditioning. No

gaseous emission abatement systems have been fitted to these two units.

Section 8.3, selected parameters were tested for homogeneity (stratification Measurements) on

each stack. Stratification measurements were conducted on each stack, as far as possible, at

low, medium and high loads. Where inhomogeneous distributions were determined, all further

parallel measurements, for the determination of the EN 14181 QAL2 process, were conducted

at the following derived representative points.

conditions such as soot blowing & boiler ashing. Each parallel measurement period was

completed over approximately three days and included a minimum of 15 measurements

covering, as far possible, high, medium and low load conditions.

3. Methods & Procedures

3.1. Oxides of Nitrogen (NOx reported as NO2) & Sulphur Dioxide

The methods selected for the determination of the Sulphur Dioxide and Oxides of Nitrogen

were EN 14792 and EPA Methods 6C respectively; EN 14792 Determination of mass

concentration of nitrogen oxides (NOx) Reference Method Chemiluminescence, also portions

From EPA 7E—Determination of Nitrogen Oxides Emissions from Stationary Sources

(Instrumental Analyser Procedure); EPA 6C—Determination of Sulphur Dioxide Emissions

from Stationary Sources (Instrumental Analyser Procedure).

These two procedures are essentially the same, with the exception of the two differing analytes

and the detection principles.

A heated stainless-steel nozzle and sampling Probe (M&C PSP 4000-H) was positioned in the

duct with the nozzle facing into the moving gas stream and a sample flow of the gas was

extracted non-isokinetically. The gas was passed through a heated ceramic filter which

separated and entrapped any particulate matter suspended in the gas. The sample gas was

then passed through a heated Teflon tube to a gas conditioning unit (M&C PSS-5) which

removed the moisture in the sample gas and reduced the gas temperature to approximately

4°C. The sample gas then continued through a Teflon tube into a manifold equipped with a

flow controller to a sample analyser where the SO2 and NOx volume concentrations were

determined utilising NDIR (pneumatic) & Chemilluminescence (cross flow modulation)

principles. The sample analyser used was a Horiba PG250 with the following specifications:

The response time on site with the M&C PSP 400-H probe and M&C PSS-5 gas cooler was

measured as 1 minute and 32 seconds for 98% concentration.

3.2. Oxygen (O2), Carbon Monoxide (CO) & Carbon Dioxide (CO2)

The methods selected for the determination of Carbon Dioxide (CO2) & Oxygen (O2) were EN

EPA CTM-030, Instrumental method with NDIR and EPA CTM – 030 with a Zirconia cell

respectively. The sampling system and procedure for the Carbon Dioxide & Oxygen was

essentially the same as that which has been described above for the Sulphur Dioxide and

Oxides of Nitrogen pollutants.

3.3. Stack Gas Temperature, Pressure and Moisture concentrations

The methods used for determining the SRM peripheral parameters, gas Temperatures, Pressures

and Moisture Content were in compliance with EPA Methods 2 & 4 and ISO 12141 –

(Determination of concentration of particulate matter (dust) at low concentrations – Manual

gravimetric method).

This general method for the moisture concentration can be briefly described as follows:

A sharp-edged nozzle is positioned in the duct facing into the moving gas stream and a sample

flow of the gas is extracted for a measured period of time. The moisture in the gas stream is

cooled and condensed in a gas cooler equipped with a silica gel trap. The volume of gas

sampled is totalised by a gas volume meter. The increase in moisture condensate, collected in

the gas cooler, is determined gravimetrically and the moisture concentration is calculated as

follows:

4. Results & Discussion

During the period from the 23rd

of November 2016 to 15th of February 2017, a series of

emission measurements were completed on Units No. 1, 2 & 5 at Kendal Power Station. The

measurements were conducted on the exhaust stacks of each unit. Included were measurements

of Oxides of Nitrogen, Sulphur Dioxide, Carbon Dioxide, oxygen, moisture, gas temperature

and gas pressure. These measurements, as previously indicated, were required for the

development of calibration functions for Automated Measuring Systems (AMS) used in the

Station’s Environmental Monitoring System.

A series of stratification measurements were conducted on each stack at low, medium and high

loads and where inhomogeneous distributions of the gases were determined, parallel

measurements for the EN 14181 QAL2 process were conducted at the derived representative

point. The parallel measurements for the velocity, temperature and pressure instruments were

however all conducted in a grid sampling pattern, comprised of two diameters at 90 degrees to

each other and with each diameter divided into 10 sections.

The measurements commenced on the 23rd

of November 2016 with stratification measurements

on Unit No. 2. The parallel measurements for this unit were all completed between the 25th &

28th of November 2016. Unit No. 1’s stratification and parallel measurements were completed

between the 31st of November and the 1

st of December 2016. Unit No. 5’s measurements were

completed during the period from the 9th to the 15

th of February 2017.

The measurements and their results were evaluated in accordance with the methods described

in EN 15259 8.1 to 8.4 & EN 14181 Section 6.3 to 6.6. The results of the stratification

measurements revealed the following:

Unit No. 5

All parallel measurements, for the determination of the EN 14181 QAL2 process, were

conducted at the following derived representative points.

Unit No. Derived representative points from SO2 Concentrations

1 Port C Point 1

2 Port A Point 2

3 Port B Point 2

With the exception of the carbon dioxide AMS on Unit No. 1, all the derived correlation

functions of the AMS’s passed the variability test as set in Section 6.7 of the Standard.

Unfortunately the carbon dioxide AMS on Unit No. 1 was not operational during the

measurement period and it could therefore not be evaluated.

Although the Carbon Monoxide AMS on Units 1, 2 & 5 theoretically pass the variability tests,

the resulting correlations, due to the extremely low CO concentrations will not be

representative of concentrations within the region of the emission limit value. It is therefore

recommended that a linear function of ŷi = 1 * xi be implemented for these AMS instead of the

derived correlation functions.

The measurement coordinates for each Standard Reference Method (SRM) measurement and

the corresponding AMS measurement of each measured parameter has been tabulated in

Appendix No. 1. These tables further indicate the gaseous SRM calibration shift measured over

each SRM measurement. The SRM results in these tables present corrected measured values.

Each data group was processed as described in EN 14185 Section 6 and the following

calibration functions and calibration ranges were derived:

5. Deviations

5.1. The NOx, SO2 CO, CO2 & O2 Automated Monitoring System (AMS) calibrations, conducted

by the instrument agents, did not include the use of reference gas material. The calibration

procedure instead references electric zero and range values to calibrate the AMS.

5.2. The NOx, SO2 CO & CO2 Automated Monitoring System (AMS) are currently not equipped

with a system for introducing reference gas into the measuring paths.

6. Recommendations

It is recommended that:

6.1. The gaseous emissions from Units No. 1, 2 & 5 at Kendal Power Station, reported to the

authorities, are calculated using the calibration functions presented in this report.

6.2. The Carbon Dioxide AMS on Unit No. 1 is corrected and that a new calibration function is

determined for this AMS.

6.3. The calibration function determined for the Carbon Monoxide AMS on Unit No. 1, 2 & 5

should be replaced with the following function:

ŷi = 1 * xi

6.4. The requirements for QAL3 as described in the EN 14181 are complied with when utilising the

AMS.

6.5. An AST be conducted as described in the EN 14181.

To determine if method A) or B) of 6.4.2 must be used to calculate the equation: i.e. SRM concentration range < or > 15% of the ELV

or ys, max - ys, min < 30 % ELV

if ys, max - ys, min > 30 % ELV use method A)

if ys, max - ys, min < 30 % ELV use method B)

ys, max 35.5

ys, min 20.4

ys, max - ys, min = 15.1

ELV 37.4 %

Therefore use Method A)

The following tables and graphs present the measured data, the calibrations functions and their

variability tests as calculated on the ESKOM spread sheet supplied by Rakesh Rampiar and Ebrahim

Patel. Only Unit No. 2 calibration functions have been presented here. The inclusion of these tables

and graphs serve to demonstrate the correlations between the ESKOM spread sheet calculations and

the calculations used by Stacklabs. The only difference is in the methods used to calculate the

calibration functions for Method A. The ESKOM & Stacklabs approaches produce the following

functions:

ESKOM NOx = 1.2337 * NOx(AMS) + 0.0000

Stacklabs NOx = 1.2337 * NOx(AMS) + 0.0000

And the calculated difference at a range value of 660 ppm is as follows:

ESKOM NOx = 1.2337 * 660 + 0.0000 = 740.2024 ppm

Stacklabs NOx = 1.2337 * 660 + 0.0000 = 740.2024 ppm

Difference = 0.0 ppm or 0.00% of a range value of 660 ppm

From this example it can be seen that the resulting differences in the two approaches are zero in the

final calculation.

Test of Variability

The variability is accepted if:

where

sD is the standard deviation of the differences Di

is the uncertainty laid down by the authorities

kv is the test parameter

The standard deviation sD is given by

= 23.36 mg m-3

The uncertainty laid down by the authorities is 20% of the ELV as a 95% confidence interval.

So the formula is: is calculate as:

=

= mg m-3

For 15 measurments the kv value is 0.9761. The test for variability then results in:

23.36 mg m-3 ≤ 112.245 mg m-3 x 0.9761

23.36 mg m-3 ≤ 109.562 mg m-3

which is fulfilled. The AMS passes the test.
