Fuji Electric Model ZPAF biomass multigas analyser

Designed as an integral part of current biomass gasification processes, the Model ZPAF analyser will provide continuous analyses of important gases, produced by the biomass processes of fermentation, from a wide range of waste products.

Using the methods of non-dispersive infrared, electrolytic and galvanic measurement principles, the analyser has dual ranges comprising: methane 0 to 20% and 0 to 100%, with a resolution of 0.1% by volume; carbon dioxide 0 to 20% and 0 to 100%, resolution of 0.1% by volume; hydrogen sulfide 0 to 500 ppm and 0 to 2000 ppm, resolution 10 ppm; and oxygen 0 to 10% and 0 to 25%, resolution 0.1% by volume.

The analyser has an array of inclusions to improve overall process system efficiency. These include: automatic zero/span calibration; communication by MODBUS RS485 and 4-20 mA; repeatability ±0.5% FS; and many contact outputs. The analyser is backed by ADT service and spare-part facilities.
