pulverizer loading can be calculated by dividing the pulverizer coal flow (kg/hour) by the pulverizer corrected capacity (kg/hour, based on moisture content, HGI, fineness). The pulverizer power consumption can be calculated under various operating parameters as (Power Consumption (KW) = Motor KW Rating x [(0.9 x pulverizer loading) + 0.1] X1.05.

Here are six of the most common causes of boiler slagging and fouling in our experience: Low furnace excess oxygen. Extreme stratifications of the FEGT flue gas lanes. High primary airflows ...

Coal pipe F9 on pulverizer B was the only pipe that met the original plant fuel specification guarantee of 70% passing 200 mesh, which is far short of the 75% minimum we use.

Abstract. Power plant boiler fuel demand is transmitted as a coal feeder speed demand to a coal pulverizer control. A speed controller operates the feeder in accordance with the speed demand, and a position controller for a hot coal transport air damper positions the hot air damper to hold the mill outlet temperature to a setpoint value and to increase or …

Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will be ground to a more uniformly fine size and dried to a greater extent. All these factors make the coal/ air mix- ture easier to ignite and, once ignited, more likely to detonate and cause an explosion. RECENT INDUSTRY TRENDS
