Description

Full scale operation of flue gas desulfurization (FGD) for coalfired boilers of electric power generating plant was started in February 1975 for the first time in Japan. Its three year operation to date proved more than satisfactory and the performance indicates even better results than those initially planned.<BR>However, experiences with operating disclosed that FGD of coal-fired boilers involved problems peculiar to coal burning, which require following considerations.<BR>1. Coal contains certain substances, such as chlorine which would unfavourably affect FGD and a definite measure should be established to control such maleficence.<BR>2. In case where gas being handled contains high concentration of SO2, a measure to counter the scaling action is necessary.<BR>3. Waste water from FGD requires sufficient study on COD removal.<BR>4. Depending on the kinds of coal, there may arise a problem peculiar to the coal being used. So, it is necessary to know the constituents and property of that particular coal, and result of the study should be reflected in designing the detail of the FGD.
