隧道窑一般是一条长的直线形隧道，其两侧及顶部有固定的墙壁及拱顶，底部铺设的轨道上运行着窑车。燃烧设备设在隧道窑的中部两侧，构成了固定的高温带-- 烧成带，燃烧产生的高温烟气在隧道窑前端烟囱或引风机的作用下，沿着隧道向窑头方向流动，同时逐步地预热进入窑内的制品，这一段构成了隧道窑的预热带。在隧道窑的窑尾鼓入冷风，冷却隧道窑内后一段的制品，鼓入的冷风流经制品而被加热后，再抽出送入干燥器作为干燥生坯的热源，这一段便构成了隧道窑的冷却带。在台车上放置装入陶瓷制品的匣钵，连续地由预热带的入口慢慢地推入(常用机械推入)，而载有烧成品的台车，就由冷却带的出口渐次被推出来(约1小时左右，推出一车)。这样的生产利于瓷器批发等大项项目的承接。——————隧道窑烧嘴
隧道窑与间歇式的旧式倒焰窑相比较，具有一系列的优点。
1、生产连续化，周期短，产量大，质量高，所生产的瓷器，比如花瓶，文具，餐具等规范化强。
2、利用逆流原理工作，因此热利用率高，燃料经济，因为热量的保持和余热的利用都很良好，所以燃料很节省，较倒焰窑可以节省燃料50-60%左右。
3、烧成时间减短，比较普通大窑由装窑到出空需要3-5天，而隧道窑约有20小时左右就可以完成。——————隧道窑烧嘴
4、节省劳力。不但烧火时操作简便，而且装窑和出窑的操作都在窑外进行，也很便利，改善了操作人员的劳动条件，减轻了劳动强度。——————隧道窑烧嘴
5、提高质量。预热带、烧成带、冷却带三部分的温度，常常保持一定的范围，容易掌握其烧成规律，因此质量也较好，破损率也少。对杯子，紫砂壶等小型器具成功率大。
6、窑和窑具都耐久。因为窑内不受急冷急热的影响，所以窑体使用寿命长，一般5-7年才修理一次。但是，隧道窑建造所需材料和设备较多，因此一次投资较大。因是连续烧成窑，所以烧成制度不宜随意变动，一般只适用大批量瓷器采购订单的生产和对烧成制度要求基本相同的制品，灵活性较差。

产品英文详情介绍
foshan electrical and mechanical equipment co., ltd. is fine burning a specialized gas burner manufacturing enterprises, the company financially sound and have strong strength, it has been recognized by many customers. the main products are gas burner, air-valve embodiment, burner control, flame detectors, combustion gas valve and so control products. a long tunnel kiln is generally rectilinear tunnel, fixed on both sides thereof and a top wall and vault, the kiln car running on the bottom of the track laying. combustion apparatus provided on both sides of the middle of the tunnel kiln, the high temperature zone constitutes a fixed - firing zone, high temperature flue gas generated by the combustion tunnel kiln under the action of the distal end of the chimney or induced draft fan, the flow direction of the tunnel kiln, while gradually preheated kiln into the article, which constitutes a section of the tunnel kiln preheating zone. in the tunnel kiln of cold air into the drum kiln, the tunnel kiln the cooling period after the article, the cold air flows into the drum and the article is heated, and then drawn into the dryer as the heat source dried green body, which constitutes a section of the tunnel cooling zone of the kiln. sagger is placed on the trolley loaded ceramic article, by preheating the inlet belt continuously slowly push (usual push machine), and the fired product contained in the carriage, it is gradually cooled from the outlet zone pushed out (about 1 hour, the introduction of a car). this facilitates the production of porcelain to undertake wholesale and other major items of the project. ------ tunnel kiln tunnel kiln burner compared to the old batch down draft kiln, a series of advantages. 1, continuous production, short cycle, high yield, high quality, the production of porcelain, such as vases, stationery, tableware standardized strong. 2, using the counterflow principle, and therefore high thermal efficiency, fuel economy, because the use of waste heat and keep the heat very well, so it saves fuel, compared with down draft kiln fuel can save about 50-60%. 3, the firing time is shortened, from the more common large kiln is attached to the empty take 3-5 days, while the tunnel kiln is about 20 hours to complete. ------ tunnel kiln burner 4, labor-saving. easy to operate only when the light a fire, and the loading and kiln kiln kiln operations are carried out, is very convenient, improved working conditions for the operator, reduce labor intensity. ------ tunnel kiln burner 5, to improve quality. preheating zone, firing zone, the cooling zone temperature of three parts, often maintain a certain range, it is easy to grasp the firing rule, and therefore better quality, less breakage rate. for large cups, teapot and other small appliances success rate. 6, kilns and kiln are durable. because the kiln from thermal shock of the impact, so kiln long life, generally 5 - 7 years before a repair. however, the materials required to build a tunnel kiln and more equipment, therefore a larger investment. due to the continuous firing kiln, the firing system should not arbitrarily change, generally apply only to the production and firing system, which requires the same basic product purchase order large quantities of porcelain, poor flexibility. tunnel kiln burner, on the choice of foshan electrical equipment co., refined fuel.
