1. Introduction

1.1. Analyser descri tion

KIGAZ 150 is a flue gas analyser with two interchangeable sensors (O2 and CO-H2).

Its main features are the following :

•Sensors protection by stopping the pump with ad ustable thresholds

•Customers management

•15 combustibles pre-programme with possibility of adding up to 5

•2 Go of memory

The analyser is supplied in a transport bag, with a magnetic protective cover, a flue gas probe and its water trap, a Li-Ion

battery and its charger, LIGAZ software, a USB cable and a calibration certificate.

This gas analyser is designed to control parameters of flue gas in exhaust duct of heating units. t can

not be used in a permanently way and/or used as an alarm system.

1.2. Main features

•Screen

Backlighted 3.5'' grey scale screen. It allows to display measured parameters in a more comfortable format for the operator.

Thanks to the zoom function (OK key), you can view on the screen the measured value in increased characters.

•Printer

The paper of the instrument is a thermal paper with a 10-year guarantee. It has an easy replacement system of the paper

(Easyload). In addition, printing is fast.

•Battery charger

The instrument is supplied 12V, 3.75A power adapter to load the internal batteries. The current loading is indicated by a

battery symbol on the top left of the screen. The red LED on the right side of the gas analyser stays on until the battery

loading is completed.

•Flue gas suction pump

The pump, inside the gas analyser, is a diaphragm pump with a motor energized in direct current directly by the instrument

in a way to get an optimal suction of flue gases.

•Flue gas probe

Probe in stainless steel with an overmoulded handle in plastic with a standard length of 15 cm (others lengths are available

as option, please see the technical datasheet for kigaz) with a fixing cone to maintain the contact tip in the duct.

•Measurement sensors

The analyser uses electrochemical sensors to measure the oxygen and the carbon monoxide (compensated in H2

hydrogen).

•Temperature sensors

Flue gas temperature is measured with a thermocouple integrated in the contact tip. The connection to the analyser is

made thanks to a single male connector compensated in temperature. K thermocouple (nickel-nickel chromium) allows

continuous measurements up to 1250°C.

The instrument has a NTC thermoresistance for the measurement of internal temperature ; this sensor is also used for the

measurement of ambient temperature.

If a temperature control of the combustive air must be performed directly by the supply duct (room sealed boiler), a Pt100

temperature probe (ref : SAP150P) will be used. It is recommended to perform this measurement to make the efficiency

calculation of the installation more accurately.

•Types of combustibles

The analyser is supplied with a memorization of technical data which characterize the 15 most known combustibles. It is

also possible to add 5 combustibles and their corresponding features.

•Calibration certificate

The analyser is calibrated by comparison with standard of metrology laboratories, which are periodically certified closed to

laboratories known at the international level. Each analyser is supplied with its calibration certificate in which, for every

parameters, are indicated the nominal value, the one measured, the admitted error limits and the found error.

•EMC compatibility

The analyser complies with n°2004/108/EC directive on electromagnetic compatibility. Document available on request.

•Water trap

The water trap is placed on the tube that links the flue gas probe to the Kigaz 150. The measured gases go through the

filtering element allowing the recovery of condensates (liquid one or solid one).

The filtering element is placed 15 cm from the analyser and is divided into 2 parts :

Introduction 9

–one recovers the liquid particles.

–the other contains a filter that stops the smallest particles in suspension and avoid them to reach the electro-

chemical sensors

Condensates are evacuated by opening the plug.

•CO protection

The analyser is equipped with the CO protection function that allows to avoid high concentrations of CO that could damage

the analyser and the sensors. The CO measurement is stopped when it exceeds a threshold defined by the user.

•Customers management

The analyser allows to record customers, theirs respective boilers and inspections. Once the features of customers and

boilers are completed in the analyser, the operator can easily assign the different measured values to a customer and his

boiler. These data can then printed and/or transferred to a computer thanks to Ligaz software.

•Opacity index measurement (optional)

It is possible to fill in the analyser with opacity index values measured according to the Bacharach scale. The analyser will

calculate the average and results will be printed on the ticket. This measurement must be performed with an opacity pump

which is available as an accessory (ref : PMO).

•Gas network leak testing (optional)

It is possible to check the tightness of an installation. For this control, use the pressure sensor used for the draft

measurement of the shaft.

•Measured values

–O2 : percentage of oxygen in flue gases

–CO : concentration of CO in flue gases

–Tf : flue gases temperature

–Ta : combustive air temperature

•Calculated values :

–λ : Air Excess : connection between the volume of combustive air and the requested volume necessary for a

combustion in stoichiometric conditions.

–CO2 : percentage of carbon dioxide in flue gases

–ΔT : difference between the flue gases temperature and the combustive air temperature

–Qs : percentage of waste heat throughout the shaft

–ηs : Lower efficiency (or sensible) : this the burner efficiency calculated according to the EN50379 standard

disposals. This is a ratio between the conventional heating power end the burner heating power. Among the

combustion losses, only the sensible heat lost with the flue gases is taken into account, neglecting the radiation

losses and incomplete combustion losses. This value is referred to LHV (Lower Heating Value) and can not be

higher than 100%.

The sensible efficiency value is to be compared with the minimum efficiency stated for the heating systems

performances.

–ηt : Higher efficiency (or total) : is the sum of sensible efficiency and the additional efficiency deriving from

the recovery of water vapour condensation contained in the flue gases. When it s greater than sensible

efficiency, then condensation is taking place. It is referred to LHV (Lower Heating Value) and can exceed

100%. The LHV is calculated by an algorithm developed by Kimo and its value must be considered as

10 Introduction

For a better measurement, the water trap must be in

vertical position.

Empty and clean the mater trap after use.

Check that both ends are well

clipped to ensure a good

waterproofness

In case of water presence, do not

forget to empty it after each use
