Air flow control arrangement for pulverizers

Abstract

An air flow control arrangement for a pulverizer includes an inner ring segment (102), an outer ring segment (104), a plurality of vanes (106), and a plurality of wingtips (108). The inner and outer ring segments are adaptably configured in a spaced relation to each other. Further, the plurality of vanes (106) is spaced apartly arranged between the inner and outer ring segments (102, 104) to form flow ducts. Furthermore, each wingtip (108) of the plurality of wingtip is detachably attached to a respective vane (106) of the plurality of vanes to be adaptably replaceable or changeable.

Description

technical field [0001] The present disclosure relates to the field of coal pulverizers and, more particularly, to an airflow control arrangement in a roll torace coal pulverizer. Background technique [0002] The airflow control arrangement in the pulverizer (also commonly referred to as a rotary throat, gas port, or vane wheel) configures the gas conduits to direct a controlled airflow into the pulverizer grinding area of ​​the pulverizer to assist in the efficient pulverization of the coal. Crush and dry and remove with pyrite. [0003] Typically, such an arrangement includes an inner ring and an outer ring, and various vanes arranged in spaced relationship between the outer ring and the inner ring. The inner ring is joined to the pulverizer grinding area and the outer ring is cooperatively welded to the inner ring with the various blades. In addition, wingtips are also welded between the inner and outer rings to the respective blades for speed control and alignment of t...
