Plastic Waste Injection Industrial Efficiency Technology amp Measures

Plastic waste can also be injected to the BF thereby reducing the demand for coke As the plastics kg of coke The Cl and PVC content of plastic waste is a concern particularly given that PVC may give rise to dioxing production and thus necessitate additional flue gas treatment Parent Process Blast Furnace System Plastic waste can also be injected to the BF thereby reducing the demand for coke As the plastics kg of coke The Cl and PVC content of plastic waste is a concern particularly given that PVC may give rise to dioxing production and thus necessitate additional flue gas treatment Parent Process Blast Furnace System

032010 Injection of coal and waste plastics in blast

Combustion and gasifiion of coal coke and plastic wastes generate the reducing gases CO and H2 that flow up the furnace As coal and coke enter the raceway they are ignited by the hot air blast and immediately combust to produce carbon dioxide and heat C O2 CO2 Since the reaction takes place in the Combustion and gasifiion of coal coke and plastic wastes generate the reducing gases CO and H2 that flow up the furnace As coal and coke enter the raceway they are ignited by the hot air blast and immediately combust to produce carbon dioxide and heat C O2 CO2 Since the reaction takes place in the

Conversion of injected waste plastics in blast furnace

Feb 9 2016 Operation of several blast furnaces proved that waste plastic WP injection makes recycling of industrial and municipal organic wastes and coke saving possible However the extent and reaction kinetics of plastic conversion are hardly explored yet Therefore a comprehensive study on WP characteristics Feb 9 2016 Operation of several blast furnaces proved that waste plastic WP injection makes recycling of industrial and municipal organic wastes and coke saving possible However the extent and reaction kinetics of plastic conversion are hardly explored yet Therefore a comprehensive study on WP characteristics

Influence of waste plastic utilisation in blast furnace on heavy metal

Waste plastics can be utilised in blast furnaces as an alternative reducing agent However the use of waste plastics also implies an additional input of heavy metals into the process The present paper investigates the extent to which this increased input influences the emissions of heavy metals from blast furnaces Waste plastics can be utilised in blast furnaces as an alternative reducing agent However the use of waste plastics also implies an additional input of heavy metals into the process The present paper investigates the extent to which this increased input influences the emissions of heavy metals from blast furnaces
