4.4 Sampling the Flue Gas Once the automatic calibration procedure has been completed and the specific fuel has been selected (See SELECT menu) the probe can be inserted into the desired sampling point. It is recommended that the sampling point be located at least two flue diameters downstream of any bend and that the probe tip is in the centre of the flue. With balanced flues and other domestic units the probe should be positioned far enough into the flue so that no air can ‘back flush’ into the probe. This will be indicated by a low oxygen reading and/or a low ‘Poison Index’ reading.

The probe depth stop cone provided with the instrument allows the probe to be used in holes whose diameters range from 8 mm to 21 mm (5/16 to 13/16 inch). The standard probe is rated at 650°C. Temperatures of up to 1100°C (2012°F) can be accommodated using an optional high temperature probe. TIP To conserve battery power, switch off the pump when you are not taking a

measurement. Use the key to turn ON and OFF the pump. 4.5 Taking a Pressure Reading With the optional pressure module fitted a flue draught measurement can be made at any time. Connect the standard probe to the pressure sensor inlet and the probe in the flue. The pressure reading will be displayed :-

CO/CO2 R . . 0.0001 P INDEX % . . . 0.01 XAIR % . . . 0.0 Prs mbar 0.00

To perform a combustion test and display draught pressure at the same time a special probe is required. Contact Kane International or Authorised Distributor for details.

4.6 Regular Checks During Sampling Care must be taken at all times not to exceed the analysers operating specifications, in particular ensure the following :- • Do not exceed the maximum temperature of the flue probe. • The analyser internal temperature does not exceed normal operating range, typically 0-

40°C. • DO NOT PLACE THE INSTRUMENT ON A HOT SURFACE. • The water trap is vertical at all times. Water condenses in the probe line and can quickly

fill the water trap when the probe is moved. Take care and watch the water trap closely. • The in-line particle filter is clean and does not become blocked. 4.7 Normal Shutdown Sequence

DO THIS EVERY TIME YOU USE THE ANALYSER Remove the probe from the flue — TAKE CARE ! THE PROBE WILL BE HOT — and allow it to cool naturally. Do not immerse the probe in water as this will be drawn into the analyser and damage the pump and sensors. Once the probe is removed from the flue press and the analyser will count down from 30 to switch off.

OFF 30

MENU TO ESCAPE

If you have not finished but press by mistake, you can press to return to normal operation and not switch OFF.

4.8 Electromagnetic Compatibility The European Council Directive 89/336/EEC requires that electronic equipment does not generate electromagnetic disturbances that exceed defined levels and has an adequate level of immunity to enable it to be operated as intended. The specific standards applicable to this product are detailed in the appendices. Since there are many electrical products in use that pre-date this Directive and may emit electromagnetic radiation in excess of the standards defined in the Directive there may be occasions where it would be appropriate to check the analyser prior to use. The following procedure should be adopted:

Go through the normal start up sequence in the location where the equipment is to be used. Switch on all localised electrical equipment that might be capable of causing interference. Check that all readings are as expected. (A level of disturbance in the readings is acceptable). If not adjust the position of the instrument to minimise interference or switch off, if possible, the offending equipment for the duration of the test. N.B. Maximum cable lengths must be less than 3 metres.

At the time of writing this manual (November 2005) Kane International Ltd is not aware of any field based situation where such interference has ever occurred and this advice is only given to satisfy the requirements of the Directive.

are correct. Press to return to SELECT menu. O2 Ref : Toxic gas measurements can be referenced to defined oxygen levels. Reference

values can be set from 1-20%, to AUTO or more normally to the default value — OFF. Setting to AUTO uses the figure in the FUEL constants data.

Oxygen referencing is required by some regulations such as TA-LUFT. If a

reference value is selected then toxic gas measurements will be displayed with the symbol (n) attached to the reading. i.e. CO(n)

What does Oxygen reference mean ? If 3 % O2 reference is selected and 5 % O2 is measured in the flue then toxic

gas values will be recalculated as if 3 % were measured. The equation for referencing is detailed in the Appendix.

Oxygen referencing prevents false readings being submitted, e.g. allowing

more air into the boiler will increase the oxygen level in the flue and hence dilute any toxic gas reading. Oxygen referencing gives readings as if they were undiluted.

SMOKE: Allows the user to enter a smoke test number from 0-9. This value will be

printed on the standard printout. Default value is OFF. RESET : Allows the user set the Oxygen to 20.9% and zero the toxic sensors without

turning the analyser off.

6. PRINTING INFORMATION Supplied as accessories for the KANE940 are an infra-red thermal printer or a dot matrix serial printer. Read the manual supplied with each printer prior to operation. Connections to the KANE940 are detailed below : • Infra-red thermal printer — this does not require a cable to transmit the data but uses an

infra-red (IR) link similar to a TV remote control. The IR emitter is positioned on the top of the KANE940 and the bottom of the printer. Ensure they are pointing at each other and within 300 mm, with no obstructions in the way. Data may be lost if transmission is interrupted. Keep the KANE940 pointing at the printer until the printout has finished.

• Dot matrix serial printer — requires the supplied serial cable to transmit data. Connect the

cable to the 8 pin DIN socket on the top of the KANE940 and the 25 pin D-connector on the printer.

Data can either be printed from a ‘live’ test or from stored data. Printing of stored data is detailed in STORING AND RETREIVING DATA. 6.1 Printing a ‘Live’ Test During a combustion test the KANE940 will print data on request.

8. MAINTENANCE 8.1 Emptying and Cleaning the In-line Water Trap The in-line water trap should be checked and emptied on a regular basis. Water vapour will condense and gather in the probe line. This may move suddenly to the trap when the probe is moved. Care should be taken at all times. Emptying of the water trap is detailed below :-

Carefully remove the end cap from the in-line housing. Dispose of the condensate in a suitable drain, care must be taken as it could be acidic. If condensate spills onto the skin or clothing, clean off immediately using fresh water, seek medical advice if problems occur. 8.2 Changing the Particle Filter This is a very important part of the analyser and should be changed regularly. It prevents dust and dirty particles entering the pump and sensors and hence causing damage. The filter MUST be changed when it is discoloured.

9. PROBLEM SOLVING The following is a list of problems that may occur on the instrument through its operating life. If the cause of the fault is not easy to identify then we advise you contact Kane International Service Department or an International Distributor for expert advice. Fault symptom Causes • Oxygen too high • CO2 too low

• Air leaking into probe, tubing, water trap, connectors or internal to instrument.

• Oxygen cell needs replacing. • Oxygen Error (FAULT) • Toxic sensor Error (FAULT)

• Calibration time set too short and instrument not allowed to stabilise

• Instrument has been stored in a cold environment and is not at normal working temperature.

• Oxygen cell or toxic sensors needs replacing.

• Analyser not holding charge • Analyser not charging

• Battery exhausted. • AC charger not giving correct output. • Fuse blown in charger plug.

• Analyser does not respond to flue gas

• Particle filter blocked. • Probe or tubing blocked. • Pump not working or damaged with

contaminents. • Probe connected to pressure connector.

• Flue temperature readings erratic • Temperature plug reversed in socket. • Faulty connection or break in cable or plug.

• Analyser automatically switches off in operation.

• Battery below alarm level. • Ambient temperature above 50°C. • Battery quickly discharging and is faulty.

• Display shows dark lines and no reponse from ON/OFF key.

• Fault has occured on the instrument electronics and requires resetting. Contact Kane International or Distibutor.

10. ANNUAL RE-CALIBRATION

Whilst the sensors have an expected life of more than two years in normal use it is recommended that the analyser is re-calibrated at least annually. This is so that long term drift on the sensors and electronics can be eliminated. Local regulation may require more frequent re-calibration and users should check with appropriate authorities to ensure they comply with relevant guidelines.

APPENDICES A — Main Display Parameters The parameters and their meanings are detailed as follows : — DATE : Analyser date. See Set-Up menu section 5.2.5 to change. TIME : Analyser time. Use Set-Up menu section 5.2.5 to change. BATTERY : Displays the battery level from 0-100%. The analyser will flash (BAT) RECHARGE BATTERY at less than 10 % of charge. With the charger

connected the display shows AC ON. NETT : Nett temperature calculated by deducting the internal AMBIENT

temperature (∆T) from the measured FLUE temperature. Displays in either °C (C) or °F (F)

and will display NOT FITTED (N/F) if flue probe is not connected. If an external INLET probe is used then INLET is deducted from FLUE. O2 : Oxygen reading in percentage %. CO : Carbon Monoxide reading indicated in ppm or mg/m3. If the figures are

referenced to oxygen then the display will show CO(n). See SELECT menu 5.2.2 for oxygen reference. The display will read

‘O2 > 20%’ if referenced values selected and instrument is in clean ambient air.

EFF (G) : Combustion Efficiency calculation displayed in percentage. Gross G or Net

N can be set see SELECT menu 5.2.3. The calculation is determined by fuel type see Appendix B for calculation. The efficiency is displayed during a combustion test, ‘- -’ is displayed while in fresh air.

CO2 : Carbon Dioxide calculation determined by the type of fuel. This only shows

a reading when a combustion test is being carried out. ‘- -’ is displayed while in fresh air.

FLUE : Temperature measured by flue gas probe in Centigrade or (Tf) Fahrenheit. Will show ambient temperature after fresh air calibration and NOT FITTED (N/F) or FAULT (FLT) if probe disconnected. INLET : Temperature measured by the optional inlet air probe. This probe is (Ti) plugged into the instrument through the RS232 socket. This figure is used to calculate the NET temperature instead of AMBIENT when fitted. AMBIENT : Temperature measured by the internal sensor, used in the NET

(Ta) temperature calculation if an INLET probe is not fitted. CO/CO2 R : The CO/CO2 ratio, is the ratio of measured CO divided by calculated CO2. It gives an indication of the following :-

• How good a gas sample the instrument is reading. • How clean the boiler is running.

For example : A new or clean domestic boiler will display a ratio of less

than 0.004, a unit in need of cleaning 0.004-0.008 and a unit in need of major overhaul will show greater than 0.008.

This only shows a reading when a combustion test is being carried out. ‘- -’

is displayed while in clean ambient air. P INDEX : The CO/CO2 ratio expressed as a percentage %, called the ‘Poison (PI) Index’ i.e. P INDEX % = 100 x CO/CO2. ‘- -’ is displayed while in clean ambient air. XAIR % : Excess air calculated from the measured oxygen and type of fuel (λ) used. During a combustion test ‘O2 > 20%’ will be displayed while in clean ambient air. Prs : Flue draught pressure reading. Displayed when pressure sensor fitted. See

UNITS menu 5.2.3. for scales. NO: Nitric Oxide reading in ppm or mg/m3. Displayed when Nitric Oxide sensor

fitted. Also displayed as NO (n) when referenced to oxygen. The display will read ‘O2 > 20%’ if referenced values selected and instrument is in clean ambient air.

NOx : Calculated total Nitric oxides displayed in ppm or mg/m3. Where NOx =

NO + P%NO, note P can be set from 0-9%, default = 5%. See SELECT menu 5.2.2. Also displayed as NOx (n) referenced to oxygen. The display will read ‘O2 > 20%’ if referenced values are selected and instrument is sampling clean ambient air.

SO2 : Sulphur Dioxide reading in ppm or mg/m3. Displayed when Sulphur

Dioxide sensor fitted. Also displayed as SO2 (n) referenced to oxygen. The display will read ‘O2 > 20%’ if referenced values selected and instrument is in clean ambient air.

O2 ref % : Toxic gas measurements can be referenced to defined oxygen levels. (O2r) See SELECT menu 5.2.2 for details.

B. COMBUSTION EFFICIENCY CALCULATION The efficiency calculation is based upon British Standard BS845. This identifies three sources of loss associated with fuel burning: Losses due to flue gasses: Dry Flue gas loss, Moisture and hydrogen Sensible heat of water vapour Unburned gas Losses due to refuse: Combustible in ash Combustible in riddlings Combustible in dust Other losses: radiation convection conduction other unmeasured losses Net efficiency calculations assume that the energy contained in the water vapour (formed as a product of combustion and from wet fuel) is recovered and the wet loss term is zero. Gross efficiency calculations assume that the energy contained in the water vapour is not recovered. Since the fuel air mixture is never consistent there is the possibility of unburned/partially unburned fuel passing through the flue. This is represented by the unburned carbon loss. Losses due to combustible matter in ashes, riddlings, dust and grit, radiation, convection and conduction are not included. Efficiency Calculation: Known Data — Fuel: Qgr = Gross Calorific Value (kJ/kg) Qnet = Net Calorific Value (kJ/kg) K1 = Constant based on Gross or Net Calorific Value: K1g = ( 255 x %Carbon in fuel )/Qgr K1n = ( 255 x %Carbon in fuel )/Qnet K2 = % max theoretical CO2 (dry basis) K3 = % Wet Loss H2 = % Hydrogen H2O = % Water Measured Data: Tf = Flue Temperature Ti = Inlet Temperature O2m = % Oxygen in flue gas O2r = Oxygen reference %

Calculated data: Tnet = Net Temperature % CO2 content in flue gas % Dry Flue Gas losses % Wet losses % Unburned carbon loss % Efficiency Tnet = Flue Temperature — Inlet Temperature Dry flue gas loss % = 20.9 x K1 x (Tnet) / K2 x (20.9 — O2m) Wet loss % = 9 x H2 + H2O / Qgr x [2488 + 2.1Tf — 4.2 Ti] simplified = [(9 x H2 + H2O) / Qgr] x 2425 x [1 + 0.001 Tnet] Wet loss % = K3(1+0.001xTnet) Where K3 = [(9 x H2 + H2O) / Qgr] x 2425 Net Efficiency % = 100 — dry flue gas losses = 100 — 20.9 x K1n x (Tnet) / K2 x (20.9 — O2m) Gross Efficiency % = 100 — {dry flue gas losses + wet losses} = 100 – {[20.9 x K1g x (Tnet) / K2 x (20.9 — O2m)]+ [K3 x (1 + 0.001 x Tnett)]} Excess Air = [(20.9% / (20.9% — 02m%)) – 1] x 100% CO2% = [(20.9 — O2m) x K2 / 20.9] Unburned fuel Loss % = K4 x CO / ( CO + CO2 ) Note: CO scaled in % Where K4 = 70 for coke = 65 for anthracite = 63 for Bituminous coal = 62 for coal tar fuel = 48 for liquid petroleum fuel = 32 for natural gas The formula for K4 is based on the gross calorific value Qgr. To obtain the loss based on net calorific value multiply by Qgr/Qnet. Since this loss is usually small this conversion has been ignored. This loss is subtracted from the efficiency. Oxygen Reference CO(n) = CO x (20.9 — O2r) (20.9 — O2m)

C. CALCULATION OF FUEL DATA For any fuel not specified by Kane International the net calorific value, gross calorific value and composition should be obtained from the fuel supplier. The following fuel data has been calculated with reference to the efficiency calculation. Example 1: Chemical composition: C 25% H2 3% H2O 50% Qnet 8.35 MJ/kg Qg 9.3 MJ/kg * Max CO2 20.4% K1n = (255 x % carbon in fuel) / Qnet (kJ/Kg) = (255 x 25) / 8350 = 0.763 K1g = (255 x % carbon in fuel) / Qg (kJ/Kg) = (255 x 25) / 9300 = 0.685 K2 = Max % CO2 = 20.40 K3 = Wet Loss = [(9 x %H2 + %H2O) / 9300] x 2425 = [(9 x 3 + 50) / 9300] x 2425 = (77 / 9300) x 2425 = 20.08 K4 = 65 (an approximation for wood) * The fuel values to program into the Analyser are as follows:

NATURAL GAS K1g K_2 K_4

: 0.763 : 20.4 : 65

K1n K_3 O2r

: 0.685 : 20.08 : 8.0
