coal pulverizer inlet duct explosion doors

Pulverizer

Depending on the required coal fineness, there are two types of classifier that may be selected for a vertical roller mill. The dynamic classifier, which consists of a stationary angled inlet vane assembly surrounding a rotating vane assembly or cage, is capable of producing micrometer-fine pulverized coal with a narrow particle size distribution.

Main Fans

This is done by mounting the fans away from the direct line of the main airway, which usually involves a 90 o deflection (or close to it), and providing a device in line with the airway that is designed to fail under pressure and release the explosion pressure (e.g.doors or a weak section of duct).

Monitoring Coal mill Performance

Classifiers • The flow of coal particles through a classifier is several times the amount of coal flowing to the burners because of the large amount of coal recirculated within a pulverizer. For example, if a pulverizer is operating at 100,000 lb/hr coal feed to the burners, as much as 300,000 lb/hr or more may be flowing through the classifier for regrinding.
