  • Is there an alternative to an expensive wet-extractive PM monitor on a stack with a wet FGD?
    Is there an alternative to an expensive wet-extractive PM monitor on a stack with a wet FGD?

    Wednesday, September 18, 2019 | Derek Stuart

    Modern coal-fired power plants use a range of methods to reduce the amount of pollution released to the atmosphere. Selective catalytic reduction is used to remove oxides of nitrogen (NOx), high-efficiency electrostatic precipitators remove particulate matter (PM) and wet flue-gas desulfurization (FGD) systems remove sulphur dioxide (SO2). An unfortunate side-effect of using a wet FGD is that the stack gases downstream are saturated with water drops. Consequently, typical instruments used for measuring PM emissions such as opacity monitors and in-situ light-scattering monitors cannot be used because they cannot distinguish between dust particles and water droplets.

  • HotSpotIR Conveyor Belts
    What is the best location to detect hot material on a coal or biomass conveyor?

    Monday, July 22, 2019 | Derek Stuart

    An infrared linescanner is an excellent tool for detecting potentially dangerous hot material on a conveyor belt. It works by repeatedly scanning across the width of the belt and using a calibrated infrared sensor to measure the temperature of the moving material. If it detects a hot inclusion such as a smouldering piece of coal, it can alert the process operator who can then take appropriate action. Such action could be to divert the material or to activate a deluge system.
