| Abstract: | The basic specification and main structure of HT-NR_3 low NO_x burner developed by Babcock Hitachi and made domestically are introduced.A special test for this burner has been conducted.It is shown that reflux zone features center circular type,the concentration distribution of coal dust is of dense-phase located outside and lean-phase inside,which match to the reflux zone location,hence a reliable ignition and combustion can be obtained.The real operation has also revealed that this burner possesses excellent low NO_x property,can meet the requirement of NO_x emission in domestic coal fired boilers. |
| Keywords: | energy and power engineering pulverized coal combustion swirl burner reflux zone low NO_x emission |
