Biomass-Coal Flame Monitoring by Digital Image Processing in a Semi-Industrial Combustion Pilot Plant

A. González, B. Peña & A. Gil
Co­firing of biomass with coal is a widely adopted strategy in order to reduce CO2 emissions in electricity generation. Among the adverse effects of biomass addition, problems derived from ash deposition in heat exchanger surfaces, leading to fouling, slagging and corrosion, have been reported and attracted special interest in recent years. However, literature concerning the influence of biomass on flame structure and combustion behaviour is scarcer. Flame monitoring by means of digital imaging allows a...
