这次的窑炉设计，是对我这个学期热工课程所学知识的一次全面系统的考察，通过实习，我必将对于一些基础的设计知识以及相关窑炉方面知识有更加深刻的了解，但要把自己所学的知识和技术与实践联系起来，也并不是那么容易所以我将尽最大努力，认真对待此次实践机会，用所学知识检验和验证理论，发现自己的缺点和不足，并作出及时的改正本次实践的设计任务是日产30000件花瓶隧道窑设计， 通过三周的努力设计，我也终于基本完成任务在设计的过程中，我考虑到了很多因素，比如节约能源，优化窑体等原则，综合运用所学知识，力求做到每一步设计都到位，注意到每一细节，全面而仔细地对整个过程进行设计计算在本次设计实践过程，我得到了指导老师的精心指导，这才使我能比较顺利的完成此次设计任务，在此我向指导老师和设计过程中帮助过我的同学表示感谢！由于本人所学知识有限，加之时间仓促，在设计过程中不可避免存许多的错误和不足，敬请老师多多指教，不宁教诲设计人：07材化2班 刘翔 2010.7.52．设计任务书一、 设计任务日产30000件花瓶隧道窑设计二、 原始数据1、 坯体组成（%）SiO2Al2O3CaOMgOFe2O3K2ONa2OI.L73.217.150.350.451.01.21.754.92、 产品尺寸：Φ200*160 产品质量2.8公斤/件；3、 入窑水分：〈1%4、 产品合格率：95%5、 烧成制度：烧成周期：15小时，最高烧成温度：1210℃（温度曲线自定）6、 窑具：SiC棚板、SiC支柱，尺寸自定三、燃料天然气COH2CH4C2H4H2SCO2N2O2Qnet(MJ/Nm3)0.20.295.63.50.30.10.1041.58焦炉煤气COH2CH4CmHnH2SCO2N2O2Qnet(MJ/Nm3)6.857.022.32.90.22.37.70.817.52液化气H2CH4C2H6C2H4C3H8C3H6C4H10C4H8C5H12C5H10Qnet(MJ/Nm3)1065161515281013110　　　发生炉煤气COH2CH4CO2N2Qnet(MJ/Nm3)30.613.24.03.448.86.753重油CdafHdafOdaf+NdafSdafQnet(MJ/Nm3)86121141.58重油裂化气CO2C3H6C2H4O2COH2C2H6CH4N2Qnet(MJ/Nm3)4.38.022.61.25.917.81.832.75.739.685（四）夏天最高气温：37℃3．窑体主要尺寸的确定3.1 窑内宽的确定产品的尺寸为200*200*160mm，设制品的收缩率为10%。

由坯体尺寸=产品尺寸/（1-烧成收缩）,得坯体尺寸为：223*223*178mm装车方法的确定：综合考虑窑的日生产任务繁重、烧成周期长等因素，决定采用SiC多层棚板装车的方法，现取5层装车棚板规格750*750*25mm，沿长度方向装3行棚板，每个棚板间距为20mm，与棚板车间距为20mm：沿宽度方向装4行棚板，每个棚板间距为20mm，与棚板车间距为20mm支柱：Φ40*175mm窑车车面的尺寸：Le（长）3100 mm Be（宽）2330 mm窑内宽取2430 mm，为改善窑内传热，使制品在烧成带受热均匀烧成带窑内宽加宽270mm，取2800mm3.2 窑内高的确定3.2.1取最高层制品与窑顶间间距为100m窑内高：H=（175+25）*5+100=1100mm取车台面高为400mm窑高：400+H=1500mm 窑车高度的确定：轨面窑车到窑车衬砖面的高度为500 mm，窑车上设200mm通道（由50mm厚耐火粘土板和粘土砖组成）窑车高度H/车=500+50+200=750 mm取拱心角=60度，则窑车装载平面至窑脚高为1000 mm3.2.2 拱高f的计算 拱心角=60度 拱高f=0.134*2340=313.6 mm3.3 窑体长度的确定每件棚板可装9件，则：装车密度=9*3*4*5=540件/车装窑密度=540/3.1=174.19件/米窑长=生产任务*烧成时间/（24*成品率*装窑密度）=300000*15/（24*0.95*174.19）=113.3 m窑内容车数=113.3/3.1=36.548 取37辆车窑车有效长度=37*3.1=114.7 m根据烧成曲线： 预热带长=113.3*5/15=37.78m 烧成带长=113.3*3/15=22.66m 冷却带长=113.3*7/15=52.87m推车时间：15*60/37=23.4min/辆 小时推车数：60/23.4=2.56 辆/h4．烧成制度的确定烧成制度包括温度制度，气氛制度和压力制度。
