  • Relationships among loss-on-ignition and unburned carbons, and the FTIR photoacoustic spectra of fly ashes

    Loss-on-ignition (LOI) and unburned carbon (UC) concentrations of fly ash are two very important indices for evaluating combustion efficiencies of boilers. They are also very important factors affecting the utilisation of fly ashes. The LOI and UC of five fly ash samples collected from different power plants were analysed. The Fourier-transform infrared (FTIR) photoacoustic spectra (PAS) of these ...

  • Continuous Emissions Monitoring Equipment – Guidance & Selection

    There has never been such a wide range of analysers and systems available for continuous emissions monitoring as there is today. In the UK there are over 12 manufacturers and distributors offering CEMS (continuous emissions monitoring systems) using a variety of technologies including UV and IR absorption, FTIR, DOAS, chemiluminescence and photoacoustic spectroscopy (PAS). The majority of CEMS ...

  • Monitoring NH3, N2O, CO2 and CH4 emissions

    In France, as in other countries, there is a need to improve knowledge of greenhouse gas and ammonia emissions from livestock production with various management options. The aim of this study was to quantify the NH3, N2O, CO2 and CH4 emissions from two pig solid manure heaps, turned and not turned, in order to examine the effect of turning on gaseous emissions and to obtain additional information ...
