3.1 Precoating is the process of applying a thin layer of absorbent material around the outer surface of a filter. Typical precoating materials include lime, diatomaceous earth, pearlite, and powdered cellulose. Precoating is usually performed for 2 main reasons: 1. New cartridge filters have low capture efficiency on submicron particles. Applying a layer of precoat increases the filters collection efficiency. 2. In heavy oil and smoke applications, new cartridge filters can easily become saturated, thus dramatically increasing
the differential pressure across the filters, resulting in lowering air flow. Applying a layer of precoat provides a "protective" or absorbing cover for the filter, which is subsequently removed by pulse jet cleaning. Typical loading rates for filters range from 0.5 to 2.5 lbs/filter.
3.2 The Amtech PCF series is designed to, continuously, inject a relatively small volume of precoat material into a dust collection system. The precoat feeding rate can be controlled by the cycle time (time on/time off) and the compressed
