Riley Power Inc.''s Combustion Optimization Program addresses mill system performance in a systematic approach to control fi neness and distribution so that slagging, LOI, CO, NOx can be optimized. First, the pulverizer system is reviewed for its ability to grind the coal and deliver balanced fuel to each burner at suffi cient fi neness.
At a time when combustion optimization seems to be such an important part of reducing emissions and improving efficiency, in part because of carbon constraints, we have to ask ourselves, how do we ...
Beater wheel mills are designed to prepare a coal powder airfuel mixture for combustion in furnace chambers of coalfreed power plants by coal drying, pulverizing, classifying and transport. Their multipurpose function usually results in operation instability accompanied by unacceptable vibration.
The velocity signal is also critical to combustion optimization as it assists with proper primary airflow control, ideal flame stability, and avoidance of problems like coal layout, pipe fires ...
This is all controlled by the coal mill or pulveriser, and its associated feeder equipment. Operation of the coal mill can affect the ramp rate of the power station and its ability to handle rapid changes in output. For coalfired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand.
