Abstract

A találmány tárgya szénporégő érintőleges bevezetéssel a pneumatikusanszállított tüzelőanyag, különösen szénpor számára, és koncentrikusrészáramokra felosztott égési levegő számára, az égőnek egy, az égésilevegőt és a szénpor-levegő keveréket vezető primer levegő csöve (4)van, amelyet egy, a szekunder levegőt vezető szekunder levegő cső (10)és egy, a tercier levegőt vezető tercier levegő cső (11) vesz körül,és hátsó tartományában egy berendezés révén a szénpor-levegő keverékbevezetésével van összekötve. A találmány lényege, hogy a szénpor-levegő keverék feladására szolgáló berendezésként egy spirál ház (3)van elrendezve, amely spirálban körbefutó radiális csatornaként vankialakítva, és a csatorna nagyobbá váló kerületi szöggel csökkentettmélységgel rendelkezik. ÓThe subject of the invention is a coal pulverized burner with tangential introduction for pneumatically delivered fuel, especially coal pulverized, and for combustion air divided into concentric partial flows, the burner has a primary air pipe (4) leading the combustion air and the coal pulverized air mixture, which is connected by a secondary leading the secondary air it is surrounded by an air pipe (10) and a tertiary air pipe (11) that carries the tertiary air, and is connected in its rear region to the coal dust-air mixture inlet through a device. The essence of the invention is that a spiral housing (3) is arranged as a device for sending the coal dust-air mixture, which is designed as a radial channel running around in a spiral, and the channel has a reduced depth as the circumferential angle becomes larger.
