QXX High-speed External CFB Boiler

ZBG manufactured QXX high-speed external CFB boiler, or energy-saving CFB boiler, represents the latest direction of CFB technology developments in China. In 2015, our QXX series 116 MW CFB boiler’s thermal efficiency reached to 91.89%, as the NO.1 among other CFB boilers. It has directly overcome the two problems of normal CFB boilers, i.e. High electricity consumption and abrasion, thus the electricity consumption can be reduced by at least 30%.

20% power saving, low bed pressure running

Low bed pressure running, it can save the power consumption of the fan by more than 20%. Coal consumption decreased by more than 3% during running of the boiler.

Low-emission, eco-friendly

By optimized classification of low temperature of NOx can be decreased to less than 100mg/Nm3, outstanding performance of the environmental protection.
