Abstract

Abstract: The oil feeding situations of supercritical unit under different load conditions (the runback is excepted.) were analyzed. According to practical situation, the judgment signal of ‘accident trip’ of the coal mill and the frequency converter were perfected. Grasping the accident omens of the fire extinction and faults of auxiliary devices, the automatic oil feeding for combustion supporting was realized; so the combustion of the boiler was stabilized effectively, the unit power generation was ensured, and the disturbance of the unit on the power grid was decreased.

Key words: accident trip, critical flame, coal mill, frequency converter, stable combustion
