ENERGY-SAVING EQUIPMENT IMPLEMENTATION IN TUNNEL KILN FOR CERAMIC BRICKS CALCINATION
The analysis of the technical decisions used in the Bulgarian projects of tunnel kilns for ceramic brick calcination is carried out. Disadvantages, caused by out-of-date heating engineering equipment, are shown on an example of enterprise of «Metekhis ceramics», Georgia. Necessary measures of modernisation of tunnel kilns for ceramic brick calcination built by the Bulgarian projects are stated. The basis of modernisation – the substituting of out-of-date gas-burning devices by modern gas-burners; expansion of calcination zone due to installing of gas-burning devices on positions of preheating zone; implementation of modern automatic control systems for thermal and aerodynamic process adjustment. The principal scheme of the tunnel kiln for ceramic brick calcination including modern heating engineering equipment and automation of adjusting of thermal and aerodynamic mode is worked out. Explanations of advantages of modern equipment and modern automation system applying for quality improvement of manufactured products, increasing of a productivity of a tunnel kiln and reducing of specific consumption of natural gas are presented.
