Bone porcelain kiln choose 2

( 4) Main structure size and technical and economic indicators from the thermal analysis of the current intermittent kiln is mostly used in the bone porcelain industry in China also has the following several aspects of the foot, the intermittent kiln energy consumption is bigger, need to be addressed. (1) the kiln body heat storage bone loss is relatively large. (2) the bone light-duty kilns, kiln car still need further. (3) away flue gas heat loss is too big (4) the operating system is not reasonable. (5) of waste heat utilization is unreasonable. 6 do not have a high level of automation control. Bone China should promote continuous intermittent kiln operation system, appropriate increase bone porcelain, bone China into the kiln temperature from the kiln, in order to use bone kiln body heat storage at low temperature stage, firing cycle can be reduced at the same time, so it can further saving energy and reducing consumption, the intermittent kiln plays a greater energy efficiency in production. Continuous kiln continuous furnace is a finger bone porcelain products, burn, cold, and the operating process is a continuous furnace. According to the continuous kiln transmission mode can be divided into the following kinds of bone China products. (1) models in tunnel kiln. (2) the roller kiln. (3) mesh belt furnace. (4) push board kiln. (5) step by step. 6 ring kiln. Among them, Taiwan model tunnel kilns of bone and bone porcelain kiln for commonly used, step by step and ring kiln using fewer, above the main kinds of kilns. According to the combustion system and continuous kiln can be divided into the following categories. (1) side type. (2) bottom type. (3) burning type between products. (4) top burning type. Bone tunnel kilns can be said to be synonymous with continuous kiln car type tunnel kiln is bone China ( Bone China) Bone biscuit firing kiln, roller kiln is a common decorating firing kiln. Compared with the intermittent furnace, continuous bone kiln has the following characteristics. 1) burning evenly. (2) production. (3) firing cycle is short. (4) high thermal efficiency. 5. Long service life. 6. Easy to implement mechanization and automation. Continuous bone porcelain kiln are generally divided into three zones, namely preheating zone, firing zone and cooling zone. Bone porcelain kiln center in the calcining zone, the heat source of fuel in the combustion, the firing on the flue gas chimney or induced draft fan's gravity to preheating zone, and is discharged from the preheating zone near the chimney. After the cooling zone in the calcining zone, the products are the calcining zone, between the calcining zone and cooling zone has a nasty cold air curtain, to cooling products, the waste heat can be recycled. Bone China products from the preheating zone, by the fire, the firing from cooling out of the kiln, and airflow direction from calcining zone to preheating zone inverse bone porcelain products and realize heat exchange, make the bone porcelain product firing. Bone tunnel kiln car type tunnel kiln or tunnel kiln, it is commonly used to burn into bone China enterprise equipment, its shape like a long tunnel, bone kilns length direction in part of the combustion chamber, the fuel in the combustion chamber combustion, supply products needed for the heat and atmosphere when firing. High temperature flue gas after combustion at high temperature induced draft fan or chimney under the suction force of the tunnel to the kiln head direction, in the calcining zone burn osteogenesis porcelain products, in the preheating zone preheating bone China products, and then through a flue, and chimneys. ( 1) The advantages of bone tunnel kilns (1) continuous firing, temperature of each part is relatively stable, less fuel consumption. (2) production. (3) long service life. (4) easy to realize mechanization and automation. (5) firing cycle is short. ( 2) The lack of bone tunnel kilns. (1) shall not adjust the temperature. (2) after the ignition is not stopped. (3) to continuous operation, 24 h operation. — Bone China cups to be continued. 。 。 。 。 。
