Abstract

The work offers a method of calculating of the energy performance of sinter charge ignition, such as the consumption of gaseous fuel, intensity and time of ignition, total amount of heat obtained from external sources and specific energy consumption of this process. The method takes into account the main features of sinter charge, sintering machine and gaseous fuels used in the ignition furnace. The connection of energy consumption for sinter ignition with fuel particle size has been established. It has been demonstrated that the energy consumption grows as particles dispersion decreases. Using numerical study of obtained dependencies the work reveals the causes of increased consumption of gaseous fuel in sintering plants of CIS countries. The main cause is increased humidity of fine Krivoy Rog iron ore concentrate, which is used at the number of sinter plants. Another reason is an old design of sintering machines that does not let to prevent uncontrolled air leaks, ensure recirculation of flue gases in sintering and cooling zones, as well as the impossibility of sintering of high layers of the charge.
