METHOD OF PRODUCING NEEDLE COKE FOR LOW CTE GRAPHITE . · Specifically, the coal tar distillate feedstock should be heated under pressure with the pressure at least about 20 psig, preferably in the range of from about 30 psig to about 100 psig. Higher pressures can be employed, but would require more expensive coking vessels.
Thickener Feedwater · An indiion of this statement can be seen on Figure IV where the maximum current density for Quarto 4 was 13 amperes per cubic meter per hour (3 amps/gpm). The slurry was also coagulated at substantially lower current densities. By comparison, the lowest effective current density at Quarto 7 was amperes per cubic meter per hour (5 amps/gpm).

Balancing Coal Pipes · The velocity data is that of the moving coal particles. (See Figure 3.) Air velocity in these pipes ranges from 110 to 120 fps. The difference between the air and coal velocities is the coal slip.
Performance Evaluation of Mills, Boiler and Fans in ThermalFor existing coal fired power plants, heat rates are typically in the range of 9,000 Btu/kWh to 11,000 Btu/kWh. A plant with the industry average heat rate of 10,300 Btu/kWh is operating with an overall plant efficiency of about 33% (3,412/ = 10,339). 5 fWhen it comes to efficiency, the first thing that we should consider are the losses.
