The feasibility of recycling utilization mode for resouces in thermal power plants

which combined three technologies

namely technology of intermediate water treatment using lime

technology of recarbonization

and technology of limestone wet flue gas desulphurization(FGD) together

has been analysed from technical principles.The deposited slags obtained from intermediate water treatment using lime

and from recarbonization treatment are used as raw materials in wet FGD using limestone

while the CO2 in purified flue gas after FGD can be used as recarbonization agent in effluent water from intermediate water treatment using lime.An approach to the problems may appear in said recycling utilization mode has been made

it is believed that the organic combination of three matured technologies above-mentioned can effectively realize the recycling utilization of resources and their wastes in thermal power plants.
