8000 Series, Blast Furnace Top Gas Analyzer - 1

8000 SERIES BLAST FURNACE TOP GAS ANALYZER Applications Designed for the continuous monitoring of O2, CO, CO2, and/or H2 gases from blast furnaces or other continuous industrial processes where an uninterrupted stream of gas concentration data is critical. Calculated values of BTU, N2 and efficiency are also available. Description The Nova 8000 series has been designed for the continuous monitoring of pre-cleaned gases from a blast furnace or other high intensity, continuous industrial processes. The analyzer measures up to four gases simultaneously - O2, CO, CO2, and H2, the ranges of which are shown below. From these readings, other operating parameters such as nitrogen content, BTU and efficiency can be calculated and displayed. The analyzer consists of three main components: a heated filter cabinet which is directly mounted on the side of the blast furnace gas main, a sample conditioning system which is integral to the main analyzer cabinet, and the gas analysis sensors which are mounted in a separate but integral rack mount drawer, which eases service and maintenance. 7240 Heated Stack Sample Filter • 8002 - CO and CO2 • 8003 - H2, CO, and CO2 with H2 compensation • 8004 - H2, O2, CO, and CO2 with H2 compensation • 8006 - 8004 gases + N2, BTU and efficiency calculation • Other gases can be included as part of this platform, including CH4, SO2, NO, and NO2 in % or PPM ranges. Options • Cabinet purge system for use in dusty or hazardous locations • Cold weather package for operation to -5°F (-20°C) • Cabinet coolers can be fitted to most models 8000 Series Blast Furnace Top Gas Analyzer

8000 Series, Blast Furnace Top Gas Analyzer - 2

8000 SERIES BLAST FURNACE TOP GAS ANALYZER Sample Conditioning • High capacity sample pump (where sample motivation is required) and high flow by-pass improves overall system response time • Compression-style moisture removal eliminates use of failure-prone pelletier elements • Redundant heated filters allow user to remotely switch from a blocked filter to an unblocked filter, minimizing down time due to filter blockage. • Automatic blow back of heated filter and probe, can be sequenced with autocalibration, or based on sample vacuum limit • Digital control maintains constant sample flow...
