Abstract
In this paper, we perform thermotechnical inspection of the operation of Lurgi-278A, OK-306, Lurgi-552A, and Lurgi-552B of SevGOK PJSC firing machines with various operating areas. The operation of various elements of the firing machine, technological drying zones, heating, firing, recuperation, and cooling was studied under industrial conditions. According to the JSC “VNIIMT” method, the following processes were analyzed and performed: the thermotechnical scheme structures of the firing machines and their operating parameters, the thermotechnical calculations of heat transfer and gas dynamics in the layer, the gas-air flow parameters of the firing machine, and the optimizing calculations in order to increase the specific productivity. As a result, technical solutions were developed to increase the specific hourly productivity of firing machines up to 1 t/m2 while maintaining and improving the quality characteristics of the finished pellets.
