Although modern flare systems are specifically designed to reduce the thermal radiation, pollution and acoustic impact of a flare, a considerable amount of radiation is nevertheless emitted by an operational flare as a result of burning large quantities of combustible gases. The emitted radiation increases the temperature of the flare support structure and nearby structures. Therefore, it is essential to correctly estimate heat transfer from the flares to the structures when designing structures, selecting their materials of construction (MoC), selecting protective paints and so on.... http://www.che.com/processing_and_handling/thermal_and_energy_mgmt/kilns_ovens_and_furnaces/9390.html Fri, 1 Jun 2012 0:00:00 EDT The Simetal EAF FAST DRI is a new electric arc furnace that is specially designed for the use of direct reduced iron (DRI).
