An iron blast furnace is assumed to be reducing pure FezO, to Fe, and all the

reduction is assumed to be performed by CO. For each 960 Kg of Fe produced there is charged 300 Kg of CaCO3, and 800 Kg of pure carbon is burned in the tuyeres. The temperature of the blast is 800C., and that of the escaping blast-furnace gas 200C. The slag is 45% CaO. The temperature of the slag and of the iron is 1600C. The melting point of the slag and of the iron is 1500C. Find:

1. The volume and percentage composition of the blast-furnace gas per metric ton of Fe produced
2. The volume of blast required per ton of Fe
3. The percentage of the total calorific power of the fuel which is developed in the furnace
4. A heat balance of the furnace per 1000 Kg of iron reduced

Q3- An iron blast furnace is assumed to be reducing pure Fe2O3 to Fe, and all the reduction is assumed to be performed by CO. For each 960Kg of Fe produced there is charged 300Kg of CaCO3, and 800Kg of pure carbon is burned in the tuyeres. The temperature of the blast is 800C., and that of the escaping blast-furnace gas 200C. The slag is 45%CaO. The temperature of the slag and of the iron is 1600C. The meltin point of the slag and of the iron is 1500C. Find: a) The volume and percentage composition of the blast-furnace gas per metric ton Fe produced b) The volume of blast required per ton of Fe c) The percentage of the total calorific power of the fuel which is developed in furnace d) A heat balance of the furnace per 1000Kg of iron reduced
