佛山市精燃机电设备有限公司是一家专门生产燃气烧嘴的企业，燃气烧嘴可以用在很多工业炉上，得到了很多用户的认可，下面精燃机电以隧道窑为例，谈谈燃气烧嘴在隧道窑上的应用。
隧道窑的热效率影响热耗的因素：窑具质量;窑车衬砖材料质量;烟气的空气过剩系数
常用的气体燃料燃烧设备(烧嘴)
气体燃料烧嘴：长焰烧嘴;短焰烧嘴;无焰烧嘴;高速调温烧嘴;脉冲烧嘴;
现代高速烧嘴的优点(相比传统气体燃料烧嘴)
(1)燃烧室的容积热力强度高，
(2) 烟气速度高，带动窑内气体作循环流动，
(3)能够燃烧低热值的燃气
(4)烟气中生成的nox含量较低。
(5)节省燃料。
脉冲(高速调温)烧嘴工作原理：燃料与助燃空气的混合气脉冲地喷入燃烧室内，在一个适当的高温气氛中爆炸燃烧，从而形成脉冲的高速高温气流——————隧道窑烧嘴
隧道窑内，装有坯体的窑车迎着气流连续式或间歇式运动，一般将其分为三个带预热带、烧成带、冷却带窑的各带长度确定的一般原则：
1.预热带长度应根据排出废气温度来确定，废气离开排烟机温度应低于250℃;
2.烧成带长度根据保温时间来确定
3.冷却带长度根据出窑制品的温度来确定，一般应低于100℃
隧道窑的结构：(1)窑体(2)窑内输送设备(3)燃烧设备(4)通风设备——————隧道窑烧嘴
隧道窑的工作系统：
1、产品烧成部分：即窑体部分，设有各种气流进出口。
2、窑内输送设备：窑车与窑具
3、排烟系统：包括支烟道、主烟道、烟囱等。
4、燃料燃烧系统：燃料输送管道、燃料预热、燃烧器等。
5、气幕搅动系统：输送风管、风机、及各种调节阀
6、冷却系统：包括急冷、缓冷、快冷。
7、推车系统：为窑车运动提供动力，液压和螺旋推车机
8、窑车回路系统：包括窑内轨道和窑外轨道以及驱动设备——————隧道窑烧嘴
窑内气体产生分层的原因：预热带处于负压，易漏入冷空气而沉在下部，热气体在其上而产生分层现象。措施：用气幕或循环装置。
气幕：在窑横断面上，自窑顶及两侧窑墙上喷射多股气流进入窑内，形成一片气体帘幕。
组成：封闭气幕;搅动气幕;循环气幕;氧化气氛幕;急冷阻挡气幕
隧道窑的自动调节
1 隧道窑是连续性窑，在正常生产的情况下，窑内的温度、气氛、压力应该稳定。
2 产品种类变更，码坯方法，燃料质量和数量波动，风量改变，天气关系或地下水影响，使烟囱抽变化以及工人操作经验不同等。
3 窑内调节的主要参数是温度，其次是气氛。
4 压力调节—保证温度和气氛的稳定。

foshan electrical and mechanical equipment co., ltd. is fine burning a specialized production of gas burners companies, gas burner can be used in many industrial furnaces, has been recognized by many users, the following refined fuel to mechanical and electrical tunnel kiln, for example, to talk about the burning of gas application mouth on the tunnel kiln. factors influence the thermal efficiency of the tunnel kiln heat consumption: mass kiln furniture; brick lining material mass kiln car; the excess air ratio of the conventional flue gas fuel combustion device (burner) gas fuel burner: burner flame length; short burning flame mouth; flameless burner; high-speed burner thermostat; pulse burner; advantage of modern high-speed burner (compared to conventional gas-fuel burner) high-intensity heat capacity (1) of the combustion chamber, high (2) gas velocity , for driving the gas circulation kiln, a lower (3) capable of burning a low calorific value gas (4) nox content of flue gas generated. (5) fuel saving. pulse (high-speed temperature control) burner works: fuel and combustion air mixed gas pulse is injected into the combustion chamber, an explosive combustion in an appropriate high temperature atmosphere, thereby forming a high-speed pulsed high-temperature air tunnel kiln ------ general principles tunnel kiln burner, kiln cars containing the blank facing the stream or batch continuous motion, is generally divided into three bands preheating zone, firing zone, each with a length of cooling zone of the kiln is determined : 1. preheat zone length shall be determined in accordance with discharging the exhaust gas temperature, exhaust gas leaving the dryer exhaust temperature should be below 250 鈩 2. the firing zone holding time length is determined according to the cooling zone 3. the temperature of the kiln length article determination, the structure 100 鈩tunnel kiln should generally be less than: (1) the kiln (2) delivery device kiln (3) a combustion device (4) ------ ventilation tunnel kiln tunnel kiln burner operating system : 1, part baked product: i.e., the kiln portion, is provided with the various gas streams and export. 2, delivery device kiln: 3 kiln with kiln cars, exhaust system: including cigarettes road, the main flue, chimney. 4, fuel combustion system: a fuel delivery conduit, a fuel preheater, a burner. 5, the air curtain agitation system: a conveying duct, fan, and a variety of control valve 6, the cooling system: including quenching, slow cooling, fast cooling. 7, the cart system: to provide power, and the hydraulic pusher 8 of the helical movement of the kiln car, the kiln car loop system: comprises a kiln rail and the outer rail and a drive device ------ kiln kiln kiln gas burner causes delamination: in the preheating zone of negative pressure, leakage into the cold air easily submerged in the lower portion of the hot gases generated in its stratification. measures: curtain or gas circulation means. air curtain: the kiln cross section, and both sides of the crown from the furnace wall into the kiln injection, multiple gas streams, forming a gas curtain. composition: air curtain closed; agitating gas curtain; recycle gas curtain; curtain oxidizing atmosphere; quenching air barrier curtain automatically adjusting a tunnel kiln tunnel kiln kiln continuity, in the case of normal production, the temperature of the kiln atmosphere, the pressure it should be stable. 2 product categories to change the code blank method, fluctuations in fuel quality and quantity, air volume change, inclement weather or groundwater influence, change and make the chimney smoke and other workers to experience different. the main parameter is the temperature adjustment kiln 3, followed atmosphere. the pressure regulator 4 - to ensure the stability of temperature and atmosphere. burner tunnel kiln, tunnel furnace combustion system, choose foshan fine electrical equipment co. burning.
