Atmospheric (non-circulating) fluidized bed (FB

The initial development focused on coal combustion in bubbling fluidized beds (BFB) with cooling tubes in the bed to maintain the desired bed temperature. Several designs were proposed (BFB, CFB (circulating fluidized bed), and pressurized BFB), as seen by a survey on FBC technology in the United States published by Fox et al. (1986).

Fluidized Bed Boiler - an overview ScienceDirect Topics

David A. Tillman, in Coal-Fired Electricity and Emissions Control, 2018. 2.1.3 Control of NO x. Fluidized bed boilers of all types are, by virtue of their combustion temperatures, low NO x generators. Operating the reactors at temperatures ≤1700°F virtually eliminates formation of any thermal NO x.All NO x is generated from the conversion of fuel nitrogen.

CYMIC boilers - using CFB technology

This also ensures low primary emissions with high combustion efficiency and excellent utilization of additives for sulphur removal and other special purposes. The key element in the CFB boiler is the cyclone. CYMIC boilers use high-efficiency cylindrical cyclones constructed of membrane walls covered by a light refractory for erosion protection.
