  79. 79. Firing System ●Firing system is a system for firing dried bricks, which consists of tunnel kiln, kiln car and operating equipment's. ●Kiln wall structure: from inside to outside, it is fire clay brick, light insulating brick, aluminium silicate thermal insulation material, and red brick. A certain distance apart, there should be equipped with expansion joints to ensure the free flexibility of kiln body. ●Continuous production, short cycle, high output and high quality. ●The heating fuel of tunnel kiln is heavy oil, light diesel oil, natural gas, coal gas and firing coal. Tunnel Kiln According to different sections, the common tunnel kiln is 3.4m, 4.6m and 6.9m. The kiln body is made of fire brick, insulating brick, aluminium silicate thermal insulation material, and red brick outer wall. The inner of kiln equips fire-resistant steel rail for operation kiln car and equips automatic operation equipment and kiln monitoring equipment. Compared with other kilns, this kiln is more energy conservation and environment protection, higher output and longer useful life (over 15 yeas).
  80. 80. The fire-resistant hanger hangs over the steel structure support, the refractory materials are filled between firebrick and fire-resistant hanger thus to ensure the tightness between firebricks. Using the fire-resistant bricks with hangers is convenient to maintain the kiln body. Firebricks in the kiln roof
  81. 81. While the kiln uses coal as the fuel, it has coal adding holes on it. And while it uses oil as the fuel, the nozzles are set at the sides of kiln body. The firebricks in the tunnel kiln are only used at the roof of firing zone and side wall of kiln body. On the premise of guaranteeing the quality of kiln body, save the cost of kiln body structure.
  82. 82. In the tunnel kiln there are rails for kiln car operation. And there are fans under the kiln cars, to make sure that the kiln car will not be burned out and it is easy to maintain. There is a pipeline at the kiln body to ensure the oxygen feeding, smoke collection and after-heat collection. The pipeline in the kiln roof will discharge the collected smoke and feed the collected after-heat to the drying chamber.
  83. 83. The two kiln doors are set at the car entering end to ensure the tightness of kiln body, the fans are set at the car exiting doors to ensure rapid cooling for fired bricks. Firebrick used in tunnel kiln Thermal insulation material
  84. 84. Kiln Car The firebrick, fired rock wool and red bricks are laid at the cast iron kiln car. The firebricks ensure the kiln car separate from the high temperature and fired rock wool ensures the tightness of fire bricks. Cast iron kiln cartwheel The kiln car is weld by the joist steel of 140mm*80mm, there is equipped with first-class cast steel idler wheel under the car. Tunnel advantages: Tunnel kiln has following features: high output, low fuel consumption, high degree of automation, low pollution, short payback period, low operating cost and low labor cost. Meanwhile, the kiln is equipped with firing system, smoke-releasing system and cooling system to ensure the firing speed and firing quality.
  85. 85. Drying system ●Drying system is used for drying the wet bricks through drying chamber and drying cart, which makes preparation for firing bricks. ●According to the different structures, the drying chamber can be divided into single-layer dryer, small section dryer and big section dryer. Drying chamber The heat source of drying chamber is from firing kiln, the heat source will be sent into drying chamber through the pipeline by heating fan, the moisture produced in drying process will be discharged by moist-releasing fan. Singe-layer Drying Single-layer drying is a drying system through on-off rack equipment to stack the wet bricks on the single pallet; it can better dry the products of high moisture content materials and high hollow rate, such as fly ash and clay materials with high moisture content. The heat source is after-heat from firing kiln and it can dry the bricks with the cooperation of moist-releasing fan.
  86. 86. Small Section Dryer Small section drying chamber applies to the production line with yearly capacity lower than 30 million, it is suitable for materials of clay, coal gangue and shale with manual stacking method, low investment and high adaptability. The heat source is after-heat, which will be sent into bottom of drying chamber by heating fan and for drying the bricks with the cooperation of moist-releasing fan.
  87. 87. Drying cart of small section drying chamber Big Section Drying Chamber Big section drying chamber is the kiln body with same size of drying chamber, it is suitable for hard materials of low moisture content, such as clay, shale and coal gangue, it is a drying method for stacking the wet bricks directly on the kiln cart of one-step stacking-firing process, it is suitable for the production line with yearly capacity lower than 30 million.
  88. 88. Stack the wet bricks on kiln cart Major component: drying chamber, drying cart, kiln car or single-layer pallet, fan and etc.
  89. 89. Operating Equipment ● SAFARA Agro Operating equipment mainly has fan, hydraulic ferry car, dragger, hydraulic pusher and hydraulic stepper. ● The fan ensures the heating supply and moisture releasing, and also ensures the air supply, moisture releasing and smoke discharging of firing kiln and cooling of kiln car. ●According to the different functions, we have moisture-releasing fan, heating fan, smoke-releasing fan, cooling fan and combustion fan. ●Ferry car, dragger, pusher and steeper ensure the safe operation of the kiln cart in the kiln. Product Information: Fan Heating Fan It is used for sending the heat of firing kiln to drying chamber and supplying the required heat for drying chamber.
  90. 90. Moisture releasing Fan Moisture-releasing fan is divided into main moisture-releasing fan and subsidiary moisture-releasing fan Main moisture- releasing fan is the major moisture-releasing fan of drying chamber and subsidiary moisture-releasing fan is the subsidiary fan for host main moisture-releasing fan. Moisture- releasing fan is installed at the roof of drying chamber; it is used for discharging the moisture and dampness in the drying chamber to ensure the drying quality. Combustion Fan Installed at the firing zone of tunnel kiln and supplies enough oxygen for firing.
  91. 91. Smoke-releasing Fan Smoke-releasing fan is installed at the above of firing zone in the kiln for discharging the smoke in the firing zone. Cooling Fan According to the different functions, the cooling fan can be divided into cooling fan at kiln door and cooling fan under the car. Cooling fan at kiln door is installed at the car outlet end for rapid cooling the fired bricks, and the blown air will ensure the air pressure balance of kiln body. Cooling fan under the car is installed under the car for cooling kiln car and preventing the kiln car from being burned out with high temperature.
  92. 92. Hydraulic Ferry Car The car used for ferrying the kiln car and for making the kiln car runs freely in the ferry line. Dragger The machine is used at the outlet end of big section drying chamber and tunnel kiln, it can pull the dried and fired car from the drying chamber or tunnel kiln to the ferry car.
  93. 93. Hydraulic Stepper Hydraulic Pusher Hydraulic pusher is used at the drying chamber and firing kiln, it will push the kiln car into drying chamber or tunnel kiln for drying or firing. Hydraulic stepper is used at the stacking process; it pushes the kiln car to cooperate with the stacker works or manual stacking.
