1. External circulating fluidized bed steam boiler advantages
Circulating fluidized bed steam boiler can be divided into the
internal circulation and external circulation types, the main
difference is the cyclic mode. Of which the external circulating
fluidized bed steam boiler is relatively of wide range of applications,
with a wide coal adaptability, high thermal efficiency, NOx emissions
low, achieve furnace desulfurization and other advantages, the
followings are the analysis of ZG circulating fluidized bed steam
boilers benefits.
1, high combustion efficiency: combustion efficiency is usually in
the range of 97.5% ~ 99.5%, compared with the pulverized coal
can be comparable to circulating fluidized bed steam outside the
boiler to maintain high combustion efficiency over a wide operating
range, and even Fueled by high levels of fuel breakdown, too, and
bubbling (circulating) fluidized bed boiler, chain boiler is impossible
to have this advantage.
2, can burn low-quality coal: external circulating fluidized bed steam
boiler without adding auxiliary fuel burning any fuel. That can be
fueled with coal, but also can be fueled with a variety of low-quality
fuels, such as high-ash coal, sulfur coal, high sulfur coal ash, high-
moisture coal, coal, coal, and oil shale .
3, high environmental performance: desulfurizer chemical required
external circulating fluidized bed steam boiler desulfurization
efficiency is up to 90%, when the equivalent ratio is only 1.5 to 2.5,
greatly reducing the sulfur oxides produced; external circulating
fluidized bed steam generators nitrogen oxide emissions at 50 ~

2. 150PPM.
4, ash utilization of: external circulating fluidized bed steam boiler
combustion process belongs to the low-temperature combustion,
while the furnace conditions are such good burn combustion boiler
ash, very low carbon content and therefore, easy to ash utilization,
do cement admixtures and building materials.
