Field test was conducted on unit peak load regulation characteristics of a supercritical boiler under different fuel conditions.The results showed that
the depth
range and speed of the peak load regulation for this supercritical 600 MW boiler were obviously affected by the coal property;the larger the calorific value of the coal
the stronger the unit load capacity;the lower the volatile content in coal
the worse the ignition and combustion stability of coal;to ensure the unit peak load regulation performance and the economic operation
low heating value of the coal should be higher than 18 500kJ/kg
and the dry ash-free volatile content should be larger than 15%.
