Basic Configuration of Circulating Fluidized Bed Boiler
Circulating fluidized bed boiler is a kind of large scale industrial application equipment with strong combustion and heat transfer function, therefore, the equipment is mostly applied in thermal power plant, winter heating, industrial processing that needs steam and hot water. This paper introduces the basic configuration of CFB boiler.
CFB Boiler mainly is composed of boiler body and boiler auxiliaries.
1.CFB boiler body.
The circulating fluidized bed boiler is improved and innovated through absorbing international CFB technology. By reducing the cycle rate and optimizing the key components structure, our boilers effectively solve the problems, such as wear and abrasion, feedback unit coking and blocking, higher boiler primitive dust emission concentration, difficulties in de-slagging and other issues. These measures make structure of the boiler more reasonable, more excellent performance, and higher safe performance.
2.CFB boiler auxiliaries
To make sure the CFB boiler operating well, auxiliaries are necessary. What’s more, their types, performance and quality are the prerequisites to ensure the safe operation of the boiler. Boiler auxiliaries mainly include 8 types:
① boiler fuel preparation system auxiliary
② boiler air/ smoke system auxiliary
③ dedusting, ash removal, blowing system auxiliary
④ slagging system auxiliary
⑤ steam and water system auxiliary
⑥ electrical and instrumentation control systems
⑦ boiler combustion system auxiliary
⑧ boiler water treatment system auxiliary
Above are the all boiler auxiliaries, but we will configure different types according to different boiler structure and demand.
Manufacturer of CFB boiler in China
We offer DHX, SHX, QXX, ZG series circulating fluidized bed boiler for steam, hot water and power need. In general, their combustion efficiency is 97%～99%, thermal efficiency is 86%一90%, compared to other coal fired boiler, the CFB boiler has lower SO2 NOx emission, effectively reducing environment pollution.
