Various industrial boilers plays an important role to complete the power generation cycle such as CFBC (Circulating Fluidized Bed Combustion), FBC (Fluidized Bed Combustion), AFBC (Atmospheric Fluidized Bed Combustion Boiler), CO Boiler, RG & WHR Boiler (Waster heat recovery Boiler).

Fluidised Bed Conversion - ProcessEng

can be made by various fluidised bed techniques working at atmospheric pressure or under pressure, usually: "bubbling" and "circulating" fluidized beds. Supercritical steam conditions can be used for fluidised bed boilers (atmospheric and pressurised) and efficiencies in the range of 45 per cent may be attained in the near future.

Bubbling Fluidized Bed Boiler - an overview . 7.3.2 Revamping of the PF boiler with a fluidized bed boiler. There are two main types of the fluidized bed boiler furnaces, the BFB and the CFB. The difference lies in the fluidization velocity, which is usually from 1.0 to 3.5 m/s for BFB, while in the CFB boiler it is 3.0–6.0 m/s. Get a Quote

6.3.2 Circulating Fluidised Bed Combustion (CFBC) Circulating Fluidised Bed Combustion (CFBC) technology has evolved from conventional bubbling bed combustion as a means to overcome some of the drawbacks associated with conventional bubbling bed combustion (see Figure 6.5).

An Introduction to Steam Generators

combustion technology in the past seventy years has been fluidized bed combustion. 1.2.1 HISTORY. Earlier fluidized bed technologies included the bubbling bed boiler. Bubbling bed boiler efficiency is similar to that of a stoker boiler (80 to 82 percent). Atmospheric circulating fluidized bed (ACFB) boiler efficiency is comparable to
