Particle-size optimization for SO{sub 2} capture by

Jan 23, 2007 · Sulfur capture by limestone particles in fluidized beds is a well-established technology. The underlying chemical and physical phenomena of the process have been extensively studied and modeled. However, most of the studies have been focused on the relatively brief initial stage of the process, which extends from a few minutes to hours, yet the residence time of the particles in the boiler …

Circulating Fluidized Bed Boilers: Design and Operations

Background Circulating fluidized-bed combustion (CFBC) is a technological offshoot of conventional FBC, designed to alleviate some of the potential limitations of conventional FBC systems, yet incorporating inherent process advantages. In comparison with classical FBC units, the CFB operates at a higher fluidization velocity (10-30 versus 2-12

Experiences in sulphur capture in a 30 MWth Circulating

The influence of different conditions on the sulfur-capture efficiency during fluidized-bed desulfurization was studied using both experimental and modeling methods. The effects of the temperature (∼1120 or ∼1200 K) and gas atmosphere (90% N2 or 90% CO2) were studied using one limestone type. The CO2 atmosphere increased the degree of conversion compared to traditional air combustion
