Description

生物质层燃锅炉防回火墙
技术领域
本实用新型涉及锅炉设计制造，更具体地说涉及生物质层燃锅炉防回火墙。 
背景技术
生物质锅炉是燃烧应用上的一项重大进步，它是利用可再生、可循环的花生壳、木屑、水稻杆、秸秆、树皮等废弃物，经粉碎、混合、烘干挤压等工艺加工成颗粒或块状生物质燃料供给锅炉燃烧，由于其原料分布广泛，数量多，燃烧污染少，加工工艺先进，它将成为新兴的绿色能源。 
目前的生物质层燃锅炉大多是采用链条式、往复式、振动式炉排，由燃料斗或给料机向炉排给料，很多生物质锅炉为了防止回火到燃料斗，采用给料机直接从前拱炉墙上向炉排给料，虽然这样不会燃烧到燃料斗，但燃料在前拱墙上直接落下后，受炉膛高温热辐射的影响，正在落下的燃料和落料口内的燃料经常会被引燃，甚至把落料口附近炉墙烧损，影响锅炉安全运行，因为有落料口，前拱上也不好安装二次风管。 
实用新型内容
有鉴于此，本实用新型针对上述背景技术存在问题，提供一种生物质层燃锅炉防回火墙，以适应生物质燃料燃烧需要，使锅炉安全运行。 
为解决上述问题，本实用新型采用了以下技术方案：生物质层燃锅炉防回火墙，包括前拱墙、落料口、防回火墙、二次风管，所述前拱墙上的落料口前加装一个防回火墙，所述防回火墙上装有二次风管。 
综上所述，本实用新型生物质层燃锅炉防回火墙，通过加装了防回火墙，降低了炉膛热量对燃料落口及正在落的燃料的辐射，保护了前拱墙，也更方便加装二次风管了，能使锅炉更安全经济运行。 
附图说明
图1是生物质层燃锅炉防回火墙示意图。 
具体实施方式
下面将结合附图，对本实用新型实施例中的技术进行清除完整的描述，显然，所描述的实施例仅仅是本实用新型的一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的其他实施例，都属于本发明保护范围。 
如图1所示，生物质层燃锅炉防回火墙，包括前拱墙1、落料口2、防回火墙3、二次风管4，所述前拱墙1上的落料口2前加装一个防回火墙3，所述防回火墙3上装有二次风管4。 
当锅炉运行时，由于有了防回火墙3，炉膛热量无法直接辐射到落料口2和正在落下的燃料，防止了前拱被烧损，防回火墙3内还可加装二次风管4，能给炉内燃烧补充更多的空气，达到安全经济运行的目的。
