According to the LNCFS burner served in supercritical 600 MW unit boilers
the influence of such factors as the oxygen content at the economizer outlet
the pressure difference in furnace
the SOFA volume
the CCOFA volume
the combination mode of pulverizers
and the auxiliary air volume on the NOx emission was investigated.The results showed that
when the LNCFS combustion system was applied on the supercritical 600 MW boiler
with unit load of 600 MW
the NOx emission concentration can be controlled below 250 mg/m3.Meanwhile
the other operation parameters of the boiler were obtained:the pulverizing system was in ABCEF coal mill combination mode;the oxygen content at the economizer outlet was 3.3%;the pressure difference in furnace was 800Pa;the third layer and fourth layer SOFA was put into service;and the opening degree of auxiliary air damper was regulated according to the furnace pressure difference curve.The result totally satisfied the environmental protection standard.
