17th, after ggh 19, enter the sox that desulfurizer 16 removes in flue gas, the neat stress after desulfurization passes through flue gas cooling device 6 again
Part moisture in removing flue gas, makes the vapor in neat stress control within 8%, net after flue gas cooling device 6 dehumidifying
After ggh 19 heating, 45%-55% therein is taken away by the first air-introduced machine b 18 flue gas as First air circulating flue gas,
Remainder is delivered to carbon dioxide compression purification devices 9 compression purification or is entered air by chimney 10.
This high effective flue gas recirculation oxygen-enriched combustion system, exports the direct flue gas extracting 40%-50% using from economizer 4
As secondary wind circulating flue gas, through cyclone separator 15, the flying dust in flue gas is separated, then pass through the second note oxygen device 12 again
Oxygen is injected, reaches secondary wind oxygen concentration requirement needed for burning, be re-fed into the secondary air channel 22 of burner 2.Due to from province's coal
The flue-gas temperature that device 4 is extracted out is about 350 DEG C -450 DEG C, and note oxygen belongs to high temperature note oxygen thereto, and the second note oxygen device 12 needs to adopt
The safeguard procedures such as special antistatic, therefore, setting Antistatic protection device is too high to avoid occurring oxygen concentration in flue, draws
Play the safety problem such as detonation, blast.Substantially 350 DEG C -450 DEG C of the secondary wind circulating flue gas temperature extracting from economizer 4 outlet,
Combustion stability is good.Further, since after partial fume is pumped, enter First air circulation exhaust gas volumn greatly reduce (about normal
The 70% of rule boiler), therefore, decrease heat loss due to exhaust gas, the required exhaust gas volumn processing of simultaneously follow-up flue gas purification system is relatively
Few, largely reduce the scale of follow-up flue gas purification system, reduce initial cost cost and operating cost.
