Iron and Steel coke CarbonKit
Metallurgical coke is the solid product obtained from the carbonisation of coal (predominantly coking coal ) at high temperature and is used as a blast furnace feedstock in the production of iron and steel. As well as producing coke this process produces coke oven gas CO 2 CH 4 and other by-products. Iron production takes place within a blast furnace. The reactor is about 30 to 40 metres high and includes a volume of up to 4.000 m3. Iron oxides and coke are conveyed from the top. The plastic waste is fed into the lower side of the blast furnace. The temperature in this part of the reactor reaches between 2.100°C and 2.300°C. Under these

Coal gasWikipedia
Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air. Town gas is a more general term referring to manufactured gaseous fuels produced for sale to consumers and municipalities.. Coal gas contains a mixture of calorific gases including hydrogen carbon monoxide methane For that 948 kg of hot metal are necessary from the blast furnace plant. That hot metal amount needs as feedstock 1256 kg of sinter 308 kg of coke pellets and lump ore and pulverized coal.
