Abstract

本发明提出的是一种燃煤窑炉。在炉体内腔的下部装有炉排，并形成燃煤层、供风排渣腔和燃烧供热腔。在炉体的外侧包裹有按重量比由岩棉、海泡石、聚乙烯醇、稀土复合胶粘剂、膨润土份和渗透剂和由空心陶瓷粉30%与多孔陶瓷微粒70%的混合物所构成的保温层，在炉体内侧涂固有按重量比由蓝晶石粉、氧化钴、赤柱石、二氧化钛、氟化硅、二氧化锆、氧化铬、氧化铈、高岭土、三氢化铝胶粘剂、石墨和氮化硼混合并用水调成的糊料的远红外反射层。由于本发明的窑炉外侧所设的保温层保温效果比通常使用的保温层效果好，内侧所设的远红外反射层能够反射炉内的传导热为辐射热，从而提高热的利用率。适宜应用在窑炉上使用。

Description

一种燃煤窑炉
技术领域
本发明提出的是热工领域用于加热的一种燃煤窑炉。
背景技术
在本发明提出以前，用于加热的窑炉炉体外侧通常设有保温层，内侧设有由耐火材料制成的衬层，由于外侧的保温层通常使用普通的保温材料制成，因而保温效果差；内侧所设有的耐火衬层只能起到耐火的作用，没有热反射的作用。所以该种窑炉热损失大，浪费能源。
为窑炉提供热源的燃煤通常直接燃烧，燃煤得不到充分的燃烧，造成燃料利用率低，热效率低。
发明内容
为了克服现有结构窑炉热损失大及燃煤不能充分燃烧的缺点，本发明提出一种燃煤窑炉。该窑炉通过在炉体外侧设置保温层，在炉体内侧设置远红外反射层来提高窑炉的保温性能和热利用性能。
本发明解决其技术问题所采取的方案是：
在炉体内腔的下部装有炉排，并形成燃煤层、供风排渣腔和燃烧供热腔。在炉体的外侧包裹有按重量比由岩棉、海泡石、聚乙烯醇、稀土复合胶粘剂、膨润土份和渗透剂和由空心陶瓷粉30％与多孔陶瓷微粒70％的混合物所构成的保温层，在炉体内侧涂固有按重量比由蓝晶石粉、氧化钴、赤柱石、二氧化钛、氟化硅、二氧化锆、氧化铬、氧化铈、高岭土、三氢化铝胶粘剂、石墨和氮化硼混合并用水调成的糊料的远红外反射层。
由于本发明的窑炉外侧所设的保温层保温效果比通常使用的保温层效果好，内侧所设的远红外反射层能够反射炉内的传导热为辐射热，从而提高热的利用率。适宜应用在工业燃煤烧结窑炉及焙烧、煅烧窑炉使用。
附图说明
图1为本发明窑炉结构图
图中，1.炉体，2.保温层，3.远红外反射层，4.炉排，5.燃煤层，6.供风排渣腔，7.燃烧供热腔。
具体实施方式
如图1所示，在炉体内腔的下部装有炉排4，并形成燃煤层5、供风排渣腔6和燃烧供热腔7。在炉体1的外侧包裹有按重量比由岩棉5～15份、海泡石40～60份、聚乙烯醇0.5～1.5份、稀土复合胶粘剂0.6～1.0份、膨润土5～15份和渗透剂0.5～1份，和0.8～1m3由空心陶瓷粉30％和多孔陶瓷微粒70％的混合物所构成的保温层2，在炉体内侧涂固有按重量比由蓝晶石粉5～10份、氧化钴3～7份、赤柱石2～4份、二氧化钛3～6份、氟化硅5～9份、二氧化锆10～20份、氧化铬10～30份、氧化铈4～8份、高岭土5～9份、三氢化铝胶粘剂0.5～1.5份、石墨10～30份和氮化硼4～6份混合并用水调成糊料的远红外反射层3。
所述保温层可以阻隔热的传导，绝热保温效果好。在窑炉外侧涂固保温层以后，当炉内温度在800℃时，保温层的外侧表面温度与室内空气温度等同。可以证明由本发明窑炉的炉体外保温层具有优异的保温隔热性能，减少了炉内热量通过炉体保温层向环境空间扩散，产生了节能的效果。
所述远红外反射层能够耐高温，并且在高温的作用下具有较高的机械强度，热反射性能好，并可以有效地将燃煤燃烧传导热与辐射热转变为远红外长波辐射，从而减少了热量的损失，提高了热利用率，同时提高了炉内的温度，缩短窑炉的烧成时间，改善了烧成质量。
本发明的窑炉可以是卧式窑炉或是立式窑炉、隧道窑炉以及旋转窑炉，也可以是燃气窑炉或电热窑炉及燃油窑炉。
