It shows that 28 % NO_x reduction can be obtained by air staging without much combustion deterioration,and 55 % NO_x reduction can be achieved with fuel staging. The study reveals that staging combustion is also effective for stoker boiler.
实验表明,空气分级在不对燃烧构成很大影响的前提下可以达到28%的NOx减排效果,而燃料分级则可降低NOx55%,可见分级燃烧对层燃炉中NOx控制也是有效的。
