摘要

The concepts of creating the uniform temperature distribution in the reheating facilities equipped with high-effective regenerators have been considered in the present work. Uniformity of the temperature in the working space of reheating furnaces favours the removal of the local high-temperature three-dimensional zones in the furnace. This causes increasing the quality of metal heating, decreasing waste of metal, harmful gas-like ejections (including nitrogen oxides) with flue gases and improving conditions of the lining exploitation of the heating facilities.High-temperature preheating of the combustion air predetermines the low consumption of the fuel in furnaces and the deep utilisation of the heat of furnaces gases. It is proposed to bring off the maintenance of the uniform temperature distribution in reheating furnaces at the expense of the new distributed three-dimensional practice of burning fuel.Organisation of the new practice of fuel combustion is connected with special conditions of mixing fuel and air, recirculation and reverse of the furnace gases. Three dimensional (volumetric) fuel combustion is ensured by the modern design of burners equipment at the expense of the structural parameters of a burner and working space of the furnace, the arrangement of the fuel combustion facilities, duct openings of flue gases and gas dynamic characteristics of the furnace gases. Solutions for ensuring volumetrically distributed fuel burning for the main types of reheating facilities: several types of reheating pits, various types of batch and continuous reheating furnaces.
