The pure oxygen ignition technology was applied in a supercritical 670MW unit boiler using inferior coal as the fuel.Several operation parameters during the cold state startup were tested
like carbon content in fly ash and coarse slag
temperature and pressure raise curves of the boilers
and the minimum oil-free combustion stabilizing capability.The results show that the pure oxygen ignition technology is especially suitable to inferior coal.This technology has significant oil saving effect
can improve the coal burnout rate and put the electrostatic precipitator into service in advance
which has great economic and environmental benefits
