The industry features of dual swirl pulverized coal burner
1. The coal consumption is decreased by 30%;
2. The consumption-efficiency >97%;
3. The slag contains<1%;
4. The burn-off rate>99%;
5. The ash emission<50mg/m³when adding a dust collector;
6. Coal flexibility, easy operation;
7. High temperature resistance and wear resistance.
