Pulverized coal were sampled isokinetically from the PC pipes. The results indicate that there is a significant mal-distribution of coal mass flow in the PC pipes. The particulate size was also coarse. As a result, the heat release from the combustion of coal occurred higher up in the boiler, leading to a flue gas exit temperature.

what are the material used in fabrication for coal mill. A forge is a type of hearth used for heating metals, or the workplace (smithy) where such a hearth is located.The forge is used by the smith to heat a piece of metal to a temperature where it becomes easier to shape by forging, or to the point where work hardening no longer occurs.
