In cyclone boilers, combustion occurs with a molten ash layer and the combustion gases flow to the main furnace; this design precludes the use of low NOX burners and air staging.67 Low NOX burners may be used in coal-, oil-, and gas-fired boilers to lower NOX emissions by about 25 to 55 percent.68 Overfire air may be used as a single NOX Get Price
develop the 600MW CFB boiler. EXPERIMENTAL The experiments were done in the CFB cold model system shown in Fig. 1. The test rig was scaled down from a 600 MW CFB boiler (8) following the scaling law proposed by Glicksman et al (9). The riser had a height of 5.5 m and the bottom section of the riser looks like a pair of pants (pant leg structure).Get Price
