1. INTRODUCTION
The two cremators at Jersey Crematorium were monitored between the 27th - 29th January 2015 to the requirements given in the UK Process Guidance Note PG5/2 (2012) for emission releases to atmosphere.
The work involved monitoring a range of flue gas components with the plant operating normally.
The plant comprises two Cremators that are designated as the model FTII. Each cremator is fitted with two nozzle mix burners utilising gas as the support fuel. The installation has no form of flue gas treatment plant fitted to abate emissions.
The plant operates under full microprocessor based automatic control that requires little manual intervention.
The cremators were manufactured, installed and commissioned by Facultatieve Technologies Limited to meet the requirements of the Environmental Permitting (England and Wales) Regulations 2010 – (EPR 2010) as relevant to cremators, summarised in the Secretary of State’s Process Guidance Note PG 5/2 (2012).
The flue ducting and test points were in accordance with the requirements of EA TGN M1.
Measurements were undertaken to enable comparisons to be made of the operation of the cremator with the requirements of the Guidance Note in terms of emission releases to air.
Additional tests were carried out to determine the releases of mercury to atmosphere via the chimney over a number of cremation cycles at the request of the Regulator. As the cremators are unabated, reductions in the emissions of mercury are not possible, other than by reducing the mass of mercury introduced to the cremator via the coffin and cadaver.
This report details the monitoring procedures used and the results obtained from this test work along with comparisons with the Guidance Note requirements and comments where appropriate.
Relevant procedures were followed to enable quality control to be maintained throughout the test preparation, site test work, laboratory analysis, calculations and reporting.

2. PROCEDURES
2.1 Total Particulate Matter
A flue gas sample was extracted and filtered to collect total particulate matter. A Whatman QM-A filter paper was used with a particle retention of not less than 99.5% at a particle size of 0.3 micron. The flue gas extraction employed techniques given in BS EN 13284 Part 1.
The sampling was conducted using apparatus in accordance with the requirements of BS EN 13284 Part 1.
This consisted of a heated known dimension Pyrex glass nozzle, heated Pyrex glass probe liner, heated Pyrex glass filter housing with Titanium filter support containing quartz microfibre filter (all heaters set to 160°C), PTFE sample line, dreschel absorption bottles, gas dryer (silica gel), sample line to pump, pump, gas meter, rotameter, pitot and impulse lines, electronic manometer, type K thermocouple, balance (for gravimetric moisture) and datalogger. Settings tables were pre-prepared to enable isokinetic flow to be maintained (based on online measurements of flue gas velocity and temperature to correct the sampling rate).
Particulate matter analysis was carried out by weighing the filter and probe rinse collection on a calibrated balance, with the media being dried and weighed prior to and following the test.
The tests reported herein were conducted to prove the performance of the cremators relative to PG5/2(2012).
2.2 Hydrogen Chloride
A flue gas sample was extracted and filtered.
A Whatman QM-A filter paper was used with a particle retention of not less than 99.5% at a particle size of 0.3 micron. The flue gas extraction employed techniques given in BS EN 13284 Part 1
The gas sample was then passed through an absorption medium of de-ionised water to collect hydrogen chloride.
The method employed was BS EN 1911 Parts 1-3.
Laboratory analysis for hydrogen chloride was carried out on the absorption medium using Ion Chromatography (IC).
2.3 Mercury
A flue gas sample was extracted and filtered to collect solid phase mercury.
A Whatman QM-A filter paper was used with a particle retention of not less than 99.5% at a particle size of 0.3 micron. The flue gas extraction employed techniques given in BS EN 13284 Part 1.
ST/DEM0753/27.01.15/ Page 5
The gas sample was then passed through an absorption medium of acidified potassium dichromate to collect vapour phase mercury.
The method employed was BS EN 13211.
Laboratory analysis for solid and vapour phase mercury was carried out on the filter and absorption medium using Inductively Coupled Plasma (ICP-OES) Spectrophotometry.
2.4 Carbon Monoxide
A flue gas sample was continuously extracted, filtered and dried before being passed through a pre- calibrated Siemens Ultramat 23/O2 infrared analyser for the on-line measurement of carbon monoxide. The analyser has a fixed range of 0-1250 mg/Nm3 and was zeroed with air and calibrated with a nominal 800 ppmv carbon monoxide in balance nitrogen gas.
The method employed was BS EN 15058.
The analyser output was continuously recorded using a Grant 'Squirrel' data logger.
For these tests a relatively high range analyser was used due to the typical pattern of carbon monoxide concentration emissions from cremators being very low (often indicated as zero) for most of the cycle, but with occasional, high, short duration spikes of CO being emitted. The convention since non- continuous emissions monitoring became a mandatory requirement for cremators during 1990, has been to attempt to monitor the magnitude of spikes, as these are often the main contributor to total CO emissions. If the mean one minute emission of CO was say 200 mg/Nm³, it would be expected that the peak concentration during that one minute averaging period would be considerably higher than this. It follows that utilising a lower range analyser would frequently understate CO emissions, despite increasing sensitivity at low CO concentrations.
2.5 Volatile Organic Compounds
A flue gas sample was continuously extracted and filtered before being passed via a heated line through a pre-calibrated Signal 3030PM Flame Ionisation Detection (FID) analyser for the on-line measurement of volatile organic compounds. The analyser was ranged 0-100 ppmv total hydrocarbons and was calibrated using a certified reference gas prior to, and following each test.
zeroed with air passed through a catalytic converter and calibrated with a nominal 50 ppmv propane in balance air gas prior to, and following each test.
The method employed was BS EN 12619.
The analyser output was continuously recorded using a Grant 'Squirrel' data logger.
Similar comments apply to VOC’s as CO, in that the analyser scaling is set to quantify the peaks that are the nature of the emission.

2.6 Oxygen
A flue gas sample was continuously extracted from the same position in the flue as the other pollutants extraction, filtered and dried before being passed through a pre-calibrated Siemens Ultramat 23/O2
electrochemical cell analyser for the on-line measurement of flue oxygen.
The method employed was BS EN 14789.
The analyser was calibrated using a certified reference gas prior to, and following each test.
The output of the analyser was continuously recorded using a Grant 'Squirrel' data logger.
2.7 Moisture
A flue gas sample was extracted and filtered. The gas sample was then passed through an absorption medium to collect any water vapour.
The method employed was BS EN 14790.
Flue gas moisture was determined gravimetrically by weighing the absorption medium and final gas drier prior to and following the test.
This was carried out alongside testing for hydrogen chloride and mercury.
2.8 Temperature
The cremator temperatures were measured by the use of calibrated Type K thermocouples.
The method employed was BS EN 13284 Part 1.
The gas temperatures were continuously recorded using a Grant 'Squirrel' data logger.
2.9 Velocity and Volumetric Flow
Flue gas velocity was found from inserting a calibrated s-type pitot tube into the flue. The pitot head pressure was then measured using a calibrated electronic manometer.
The method employed was BS EN 13284 Part 1.
The electronic manometer output was continuously recorded using a Grant 'Squirrel' data logger.
Flue gas velocity was then calculated from Bernoulli's equation as the density of the flue gas was known (from measurements of flue gas moisture and temperature).
Flue gas volumetric flow rate was found from the measurement of the flue duct size and hence its area and corrected to normalised conditions (again from measurements of flue gas moisture and temperature).

4. COMMENTS
The results from these series of tests demonstrate that the plant satisfies the requirements of PG5/2(2012) for the releases to air of particulate matter, hydrogen chloride, carbon monoxide and volatile organic compounds for both cremators.
The cremators operated satisfactorily during testing without any failure or alarm events.
No visible chimney emissions were observed throughout the test work.
Mercury emissions vary widely as would be expected. The mercury releases are not governed by cremator operation, but are directly related to the mass of mercury introduced to the cremator within the cadaver, in the form of dental amalgam tooth fillings. All tests are in excess of the UK mercury emission limit value of 50 µg/Nm3c for abated plant. There is no emission limit value set for unabated plant.
