Pulverized coal enrichment device and pulverized coal burner applying same

一种煤粉浓缩装置和应用该装置的煤粉燃烧器

Abstract

The utility model discloses a pulverized coal enrichment device which is used to separate thin and thick solid fuel, which comprises a main body (1) which is in a space geometrical structure; the main body comprises a windward side (2) and a lee side (3); and at least a diversion hole (4) is arranged between the windward side (2) and the lee side (3) of the main body (1). The pulverized coal enrichment device adopts an enrichment impinging guiding separation principle, the resistance is obviously reduced, so as to flexibly adjust the size of the pulverized coal enrichment device within a certain scope of specification. The utility model also discloses a pulverized coal burner applying the pulverized coal enrichment device.
本实用新型公开了一种煤粉浓缩装置,用于实现固体燃料的浓淡分离,其包括:具有空间几何结构的主体(1),所述主体包括迎风面(2)和背风面(3);所述主体(1)的迎风面(2)与背风面(3)之间开有至少一个导流孔(4)。应用本实用新型,由于其运用了浓缩撞击导向分离原理,使阻力显著降低,且便于在一定规格范围内灵活地调整煤粉浓缩装置的尺寸。本实用新型还公开了一种应用所述煤粉浓缩装置的煤粉燃烧器。
