  • Page 7: Important Information

    1.1 Information about this manual This manual describes the operation and the characteristics and the maintenance of the Combustion Analyzer Chemist 500. Read this operation and maintenance manual before using the device. The operator must be familiar with the manual and follow the instructions carefully.

  • Page 8: Safety

    This chapter describes the areas of application for which the CHEMIST 500 is intended. Using the CHEMIST 500 in other application areas is on the risk of the operator and the manufacturer assumes no responsibility and liability for loss, damage or costs which could be a result. It is mandatory to read and pay attention to the operating/maintenance manual.

  • Page 9: Working Principle

    WORKING PRINCIPLE 3.1 Working principle The gas sample is taken in through the gas probe, by a diaphragm suction pump inside the instrument. The measuring probe has a sliding cone that allows the probe to be inserted in holes with a diameter of 11 mm to 16 mm and to adjust the immersion depth: the gas picking point must be roughly in the centre of the flue section.

    Remove the instrument from its packing and check it for damage. Make sure that the content corresponds to the items ordered. If signs of tampering or damage are noticed, notify the SEITRON service centre or agent immediately and keep the original packing. A label at the rear of the analyser bears the serial number. This serial number should always be stated when requesting technical assistance, spare parts or clarification on the product or its use.

  • Page 19: Checking And Replacing The Batteries

    If battery charge appears to be low, let it discharge completely and then carry out a full 100% charge cycle by connecting the instrument to the power pack for 3 hours. If the problem persists, replace the battery pack with a SEITRON original or contact the SERVICE CENTRE to carry out the necessary repairs.

  • Page 21: Gas Sampling Probe

    7.4.1 Gas sampling probe The gas sampling probe is made up of an INOX steel tube with a plastic hand grip and an internal K-type thermocouple (Ni-NiCr) for measuring the gas temperature up to 800°C. Flue gas temperature is measured by means of a thermocouple inserted in the tip of the probe.

  • Page 22: Connecting The Tc-K Probe

    7.4.4 Connecting the TcK probe Using the same input as for the K thermocouple "T1" (the same used for gas temperature), it is possible to measure the water delivery and return temperature by connecting some special probes. If temperature is taken on the pipe, it is suggested to use arc probes with a suitable diameter.

    14.6 CxHy sensor for measurement of the unburnt hydrocarbons The unburnt hydrocarbons are chemicals produced by an incomplete combustion of molecules (hydrocarbons) made of Carbon and Hydrogen. These are usually named as HC or (better) CxHy: when this is filled with the actual values for the number of C and H atoms, the actual type of fuel is exactly defined.
  • Page 154 Installing the CO sensor When the CO (position S3/S4) is mounted in the CHEMIST 500, it is mandatory to configure the autozero by setting it at 60 seconds, in order to allow for a proper pre-heating of the sensor itself. Configuration→Analysis→Autozero (SEE SECTION 9.2.6)

    14.8 Sensor for combustible gas leaks In order to detect gas leaks in plant, pipes and appliances the CHEMIST 500 requires an internal semiconductor sensor forgas leaks. This sensor responds to both CH4 (Methane) and LPG (IsoButane and IsoPropane) as well as several other combustible gases (hydrocarbons).

    Do not extract flue gas samples directly without using a particulate/water trap. Do not exceed sensor overload thresholds. When the analysis is over disconnect the sample probe and let Chemist 500 draw fresh air for a few minutes, or at least until the displayed parameters return to their original values.

    15.4 Maintaining the water trap / filter unit To remove the water trap, just rotate the cover and unhook the filter holder body; remove the internal cup and then replace the filter (see figure on the side). Clean all the filter parts using water only, dry the components and reassemble the filter. 15.5 Replacing the particulate filter If the particulate filter appears black, especially on the inner surface (see adjacent example), it has to be replaced immediately.

  • Page 173 Legislative Decree 192/2005 and the UNI 10389-1 standard Preamble It is Seitron's intention, by means of this compact guide, to provide boiler installers/service technicians with a quick and easy way to understand whether a boiler conforms to the requirements of Italian Law no. 10 dated January 1991, and subsequent modifications and supplements, and Legislative Decree 192/2005.
  • Page 174 Stack loss is calculated by applying a simple formula which relates it to other easily measurable parameters: Qs = A2 + B Tf-Ta Where: A2, B = factor that depends on the fuel used Tf = flue gas temperature Ta = combustion air temperature = % carbon dioxide in the flue gas Thus in order to calculate the stack loss and hence the thermal efficiency of a plant, one must measure the two temperatures (flue gas and air) and the level of carbon dioxide contained in the flue gas (% CO...

  • Page 176 Instructions for accurate testing In order to achieve a certain degree of accuracy when conducting flue gas analysis, the following should be respected: the boiler being checked should be running in steady state conditions. the flue gas analyser should be switched on at least 3 minutes before testing (time to auto-calibrate) with the probe located in fresh air.
