The coal producers interest in blending results in maintaining a particular coal “specification” with consistent product, at a competitive price with maximum profit. In other words, the coal producer wants to meet contracted specifications for ash, sulfur, BTU, and moisture without exceeding or failing these same requirements.
The blending of coal assists utilities in conforming to government clean air regulations. Additional benefits include enhanced boiler efficiency and control, boiler maintenance, and reduced fuel coats.
Typical coal blending applications are done using either Conveyor Belt Scales or Weigh Belt Feeders
