External lube oil systems are also used for cooling the oil in the gear box, which consists of a motor driven pump, cooler and filter. To prevent coal entering in to the Gear case, an air sealing system is provided. Hot primary air for drying and carrying pulverized coal, enters through insulated Mill side and Liner Assembly.
4.4 SYSTEM CURVE The system curve is a plot of the Total Head vs. the flow for a given system. The higher the flow, the greater the head required (see Figure 4-9). The shape of the system curve depends on the type of system being considered. The system curve equation for a typical single outlet system such as in Figure 2-10 is:
3. 2.Coal pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transport to the boiler ...

• Hydraulic Presses - Hydraulic Presses utilize hydraulics system to deliver a controlled force. Tonnage can vary from 20 tons to 10,000 tons. Strokes can vary from 10 mm to 800 mm (0.4 to 32 in). Hydraulic presses can deliver the full power at any point in the stroke, variable tonnage with overload protection, and adjustable stroke and speed.
Receiving System Large pit openings and deep pits can accommodate full truck or rail car loads, but require dust control systems to keep free falling ingredient dust within the pit. Dust control system requires 45 cm/m of air per 1 square meter of grate area. 3M x 3M grate requires 406 cm/m of air for dust control.
