CFD MODELING OF SO2 CAPTURE USING LIMESTONE

The unsteady state computational fluid dynamics model for gas-solid particle flow in industrial scale circulating fluidized bed boiler combining with combustion and desulfurization (using limestone solid sorbent) chemical reactions, both homogeneous and heterogeneous, was developed in this study. The effects of solid sorbent feeding position and solid sorbent particle size on sulfur dioxide ...

Circulating Fluidized Bed Combustion

• The bubbling fluidized bed combustion boiler is primarily a process device capable of generating power up to 30 MWe • Circulating fluidized bed combustion boilers are mainly for medium and large power • CFBC boilers offer greater flexibility as shown in Figure 12.9. Table 12.4 brings out the differences between the two combustion systems.

Influence of Sorbent Characteristics on Fouling and ...

125 MWe circulating fluidized bed combustion (CFBC) boiler experienced severe fouling in backpass of the boiler leading to obstruction of gas flow passage, while using high sulfur lignite with sorbent, calcium carbonate, to capture sulfur dioxide. Optical microscopy of the hard deposits showed mainly anhydrite (CaSO 4 ) and absence of intermediate phases such as calcium oxide or presence of ...

Mechanical Activation of the Ca-Rich Circulating

Mechanical activation of the calcium-rich fly ash formed in circulating fluidized bed combustion (CFBC) boilers was investigated to enhance the compressive strength performance of the pastes. We studied the effect of the activation on the physical, chemical, and mineral characteristics of fly ash and its pastes. Our study shows that already a short mechanical activation yields a 10-fold ...

Fluidized Bed Combustion Газогенераторы МСД

Circulating fluidized bed combustion boilers with much longer residence time (due to ash recirculation) and higher turbulence and hence higher combustion efficiency. By the 1990s, BFBC boilers practically ended the reign of the stoker-fired boilers world­wide, at least for prime fuels such as coal and lignite.

2019-11-8  Doosan Lentjes and the local EPC contractor EKON are currently building a wet limestone flue gas desulfurization (FGD) plant. Located in Çan/Çanakkale, the FGD plant is being installed downstream of two existing circulating fluidized bed (CFB) boilers each with a capacity of 160 MWe.

Comparison of ground bottom ash and limestone as

The number of fluidized bed power plants is growing rapidly due to economic and environmental benefits. These facilities produce larger quantities of bottom ash than conventional boilers. This ash exhibits pozzolanic activity once ground, but due to regulation limitations this by-product is nowadays destined to landfill. Blended cements are the most common cements in Europe and their ...
