The ground coal is stored in a large silo from where it is withdrawn at metered rates to the primary air pipe (see Fig. 2.3). This grinding system does not have to be operated continuously as the capacity of the coal silo is usually sufficiently large to hold a supply of coal for up to 10 h.
As it was shown in (23), the cost of oil comprised about 31 percent of the total product cost of the beneficiation plant or $14 per ton of coal processed. Total process capital and fixed costs comprised about 8 percent and cost of electricity for coal grinding about 2 percent of the total product cost. (No. 2 fuel oil at a rate of 10 percent on ...
assumed that the coal grinding and firing system is operated at least at minimum design capacity. The HAZOP Study of coal grinding and firing systems addresses the following aspects: 1. The hazards of the coal grinding and firing process. 2. Engineering and administrative controls applicable to the hazards and their interrelationships. 3.

This project studied the relationship between PSD and power plant efficiency, emissions, and mill power consumption for low-rank high-volatile-content Alaskan coal. The emissions studied were CO, CO {sub 2}, NO {sub x}, SO {sub 2}, and Hg (only two tests). The tested PSD range was 42 to 81 percent passing 76 microns.
The coal preparation plant receives raw coal from two different sections (Section 1 and Section 2) of Illinois No. 5 coal seam blended in a desired ratio (e.g., 75% from Section 1 and 25% from ...

In the case of coal-grinding or storage (as one might find in a cement plant) it is not possible to remove the fuel (coal) or ignition source (grinding energy, heat, static charges) and so one has to concentrate on removing the third necessary component - O 2. This fact has given rise to inerting systems that rely on the use of inert gases.
