  • An analysis of extinction coefficients of particles and water moisture in the stack after flue gas desulfurization at a coal-fired power plant

    Two important factors that affect in-stack opacity—light extinction by emitted particles and that by water moisture after a flue gas desulfurization (FGD) unit—are investigated. The mass light extinction coefficients for particles and water moisture, kp and kw, respectively, were determined using the Lambert-Beer law of opacity with a nonlinear least-squares regression method. The ...

  • Can the Solar Hourglass serve as a CSP landmark?

    A CSP project proposal has won first place in the 2014 Land Art Generator Initiative (LAGI) competition, but can the design make it beyond paper? By Heba Hashem October was an eventful month for Santiago Muros Cortés. The Argentina-based architect impressed the jury in Copenhagen with his plan for a Solar Hourglass that ...

  • Stellio heliostat set to cut CSP tower costs by 20%

    A new heliostat modeled on South African data is using a pentagonal reflector design, innovative construction techniques and smart software to boost the cost efficiency of tower plants. Heliostat fields typically contribute about 50% of the capital investment for CSP tower plants, according to a study by SBP Sonne, the German engineering firm which has ...
