Portable Emissions Analyzer Introduction Introduction 1.1 Overview The Teledyne Analytical Instruments (TAI) Model PEM-9004 Gas Analysis Computer is a multifunction analyzer with integrated calculating functions. The system is ideally suited for monitoring heaters, exhaust lines, and other flue gas installations. The PEM-9004 analyzes the gaseous products of a combustion process and provides critical information on the state of the effluent stream.
Introduction PEM-9004 Table 1-1: Measurement Capabilities of the PEM-9004 Analyzer Measured Values T.Gas Waste or flue gas temperature °F or °C T.
Portable Emissions Analyzer Introduction 1.2 Features • Analysis Ranges: The PEM-9004 is available with the following analysis ranges: • O2 0-20.
Introduction PEM-9004 • Unit Conversion: Gas, temperature and pressure information is displayed and/or stored in several different units depending on the user’s preference. • Internal Infrared Thermal Printer: The PEM-9004 is equipped with a printer for immediate hard copy of data. If desired, the printed reports can contain a header with the company name or other convenient designation. • Display: Hi-res LCD module with 5 or 10 line text and graphical display plus menu line.
Portable Emissions Monitor Operational Theory Operational Theory 2.1 Introduction The PEM-9004 uses state-of-the-art sensor technology for accurate measurements of O2, CO/H2, CO-high and optionally, NO and SO2. The sensors employed are electrochemical cells specific for each component. The instrument will measure and display the actual gas concentration for O2 and CO(H2).
Operational Theory PEM-9004 2.3 Specific Sensor Network The sensors employed in the PEM-9004 operate according to Faraday's Law of Electrolysis: In an electrochemical cell, the rate at which gas is produced at one pole is directly proportional to the quantity of electric current flowing through the electrodes. Conversely, the current produced by the cell is directly proportional to the consumption of gas at the pole.
Portable Emissions Monitor Operational Theory 2.4.2 Calculating the Waste Gas Loss The analyzer uses the measured oxygen concentration and the exhaust gas and ambient temperature of the stack to calculate the total energy loss in the exhaust gas. The total energy loss is calculated by adding in the work done to expand the exhaust gas against atmospheric pressure and the heat required to vaporize the water generated in the burning process.
Operational Theory PEM-9004 The calculation is done on a dry basis. This means that the term representing the energy necessary to heat the water vapor from ambient to exhaust temperature is omitted. To obtain the precise value for combustion efficiency one must account for many variables. The most important are: • Radiative heat losses • Variation in fuel composition • Air that leaks into the flue gas mixture raising oxygen reading • Heat loss in ash • Incomplete combustion • Boiler blowdown.
Portable Emissions Monitor Operational Theory 2.4.5 Calculating Undiluted CO Concentration To calculate the uncompensated CO concentration the PEM-9004 uses the excess air as calculated above and the hydrogen compensated value sensed by the CO electrochemical cell to arrive at an undiluted CO concentration in ppm. The following equation is used: CO(0%) = CO × Lambda Where: Lambda is the excess air as calculated above. 2.
Operational Theory PEM-9004 Figure 2-4: Gas Conditioning System The gas is passed through a condensation trap to remove moisture which would otherwise interfere with the measuring process. CAUTION: THE WATER TRAP SHOULD BE EMPTIED AFTER EACH USE. IF WATER IS ALLOWED TO COLLECT IN THE TRAP IT COULD BACK FLOW INTO THE GAS LINE AND DAMAGE THE PUMP AND SENSORS.
Portable Emissions Monitor Operational Theory CONNECTED TO THE GAS OUT PORT AND VENTED PROPERLY. USE CAUTION WHEN CHANGING FILTER ELEMENTS OR OTHERWISE OPENING ANY PORTION OF THE SAMPLE SYSTEM. ALWAYS PURGE THE SAMPLE SYSTEM TO REMOVE ANY TOXIC OR FLAMMABLE GAS FROM THE LINES BEFORE PERFORMING ANY MAINTENANCE ON THIS INSTRUMENT.
