Coal based Direct Reduction Rotary Kiln Process – IspatGuru. Coal based direct reduction process is based on the solid reducing agent which is noncoking coal. The reaction takes place at high temp (1000 deg C to 1100 deg C). Coal plays a dual role in the kiln. Part of coal is used as fuel to supply the desired heat so as toОнлайн ...

coal. The reducing gas is a mixture majority of hydrogen (H 2) and carbon monoxide (CO) which acts as reducing agent. This process of directly reducing the iron ore in solid form by reducing gases is called direct reduction.

However, a predicted temperature profile can be constructed based on the temperature of the kiln gas and the state of the solid inside the kiln [39]. About 40% of total thermal energy is required in the kiln to complete the clinkerization process. Depending on the process type one or more alternative fuels can be utilized in the kiln along with the primary fuel, coal. Typically, alternative ...

Process. Direct reduction processes can be divided roughly into two egories: gasbased, and coalbased. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
