Energy Saving Technology of Tube Heating Furnace With the development of industrialization, petroleum, as an important form of energy, drives the development of the entire petrochemical industry such as petroleum refining and petrochemical industry. So far, the petrochemical industry has been a pivotal sector in the world economy. In these industries, the main process medium heating furnace currently used is the tube furnace, which has the following main characteristics.Improvement of Machinability of Parts by Vacuum Heat Treatment Due to the flow in the tube, the heated medium is limited to gas and liquid. Usually these gases or liquids are usually flammable and explosive substances, which are relatively dangerous and the operating conditions are relatively harsh. The heating method is mainly direct type, the fuel is liquid or gas, the operation period is long, and the operation is continuous and uninterrupted.Vacuum Quenching Technology of Aluminum Extrusion Die Heap furnace, which refers to the principle of kettle steamer. The heat-absorbing surface is a group of tube bundles, and the connecting elbows between the tubes are also placed in the furnace. Since the burner is directly installed under the tube bundle, the heating intensity of each row of tubes in the furnace is uneven. When the bottom row of tubes is heated as high as 50000~70000kcal/m2·h, but the top row of pipes is less than 800~1000cal/m2·h, so the bottom row of pipes is often burned through, and the joints between the pipes are easy to loose and leak, causing fires.HD700-3D/HD1000-3D/HD1250-3D HIGH SPEED 3D CNC BEAMS DRILLING LINE The pure convection furnace was considered to be because the radiant heat was too strong, so it was changed to a pure convection furnace. All the furnace tubes are installed in the convection chamber, and the convection chamber is separated from the combustion chamber by a partition wall to prevent the furnace tube from being directly scoured by the flame. However, during the operation, it was found that the top row tubes of the convection chamber were often burned out, and the heating of the furnace tubes was still very uneven. This is because the high-temperature combustion flue gas fails to exchange heat with a heat-absorbing surface before entering the convection chamber, and the temperature at the entrance of the convection chamber is as high as 1000 °C.HDZL SERIES SINGLE SPINDLE HIGH SPEED CNC BEAMS DRILLING MACHINE
