Furnace Technology involves the design, operation, and optimization of furnaces used for heating materials in various industrial processes. .
Answer:The main types include blast furnaces, electric arc furnaces, induction furnaces, and rotary kilns.
Answer:A blast furnace is used for smelting iron ore to produce pig iron, which is then used to make steel .
An electric arc furnace heats materials through an electric arc generated between electrodes and the metal charge, melting the metal for refining or alloying.
Furnace efficiency measures how well a furnace converts fuel energy into usable heat, impacting fuel consumption and operational costs.
Refractory lining protects the furnace structure from high temperatures and chemical attack, enhancing the furnace's durability and efficiency. .
A recuperator is a heat exchanger that recovers heat from exhaust gases to preheat incoming air or fuel, improving furnace efficiency.
Temperature is controlled using thermocouples, pyrometers, and control systems that regulate fuel input and air flow.
Common fuels include natural gas, oil, coal, and electricity, chosen based on availability, cost, and process requirements.
Proper ventilation ensures the removal of exhaust gases and maintains an adequate supply of oxygen for combustion, ensuring safe and efficient furnace operation.
