Hot Test of Emission in a Industrial Scale Circulating Fluidized Bed Boiler
YANG Hai-rui; LU Jun-fu; XING Xing; et al.
Measurement of emission is carried out in a 75t/h CFB boiler with the patented water-cooled square separator. The effect of primary air ratio, bed temperature, Ca/S, load and circulating ash rate on the emission of S0_2. NO_X CO and carbon content in fly ash is investigated. The measurement results show that the high primary air ratio and high Ca/S would cause increasing, not only sulfur capture efficiency, but also the NO_X emission. The high circulating ash rate is favor for combustion efficiency. For a constant primary air bac, the emission of NO_X, CO increases with the load.
