Application of the High-Temperature Low-Oxygen Combustion Technology in Tanggang High-Speed Wire Mill

In order to achieve high efficiency, energy saving and low contamination emission for a reheating furnace with the high-temperature low-oxygen combustion technology, a regenerative combustion system of the furnace was designed by the way of numerical simulation, and a set of patent technologies was developed by the theory of metallurgical reaction engineering. An applied result of the patent technologies in Tanggang High-Speed Wire Mill indicated that the energy consume is 0.879 GJ/t, the thermal efficiency of the furnace exceeds 67%, the temperature of emission exhaust gas from the regenerator is below 160℃, and the NO_x content in exhaust gas is less than 40×10^-6 in voluminal fraction.
