Coal moisture Measurement

Measurement target: Blended coal (humidity-controlled coal)

• Measurement target: 4-15% HO
• Benefits of measurement: Coal fed into coke ovens is a mixture of different brands from different regions, dried and conditioned. By controlling moisture at this stage, it is possible to save energy in the coke oven. In addition, by measuring moisture of each raw material before mixing, it can also be used to set the mixing conditions (measurement correction).
• Key point: calibration curve will change depending on the blending conditions and type of coal. The smaller the coal particle size, the more accurate the measurement (≦5mm). Also, the sample itself has a low reflectance and is less sensitive than normal samples, so to improve measurement accuracy,
