- 摘要：
- In order to reduce overall fuel consumption, or partially substitute a “valuable” fuel with a poor one, in electric power plant boilers, oxygen enrichment of combustion air can be very effective. The paper proposes an oxygen-enriched ignition system which based on the existing pulverized coal fired boiler ignition devices. Small coal particle is suitable for this system. The new burner includes inside, outside and middle casings. And it transfer heat in two ways of downstream and upstream. The burner has authorized a patent in China. A numerical simulation theory were used to analysis it. The results indicate that: it can increase the maximum burning velocity ( )max dw/dt and the average burning velocity(dw/dt)mean , and decrease ignition temperature Ti and burnout temperature Tb ofpulverized coal. In addition, the pulverized coal fired boilers are easier to be ignited and thecomprehensive combustibility index S is improved. At the same time, it demonstrates that itis an effective way to warm-up the pulverized coal in ignition of the boiler in the powerplant.
