called compound ﬂuidized bed ash cooler (CFBAC). The CFBAC combined the major technical features of spouted bed and bubbling bed, and needed a smaller quan-tity s of ﬂuidizing air to work in the bubbling bed regime. They conducted experiments on a cold test rig and showed that (the new ash cooler had an excellent adaptability on the bottomash,
Reducing Ash Agglomeration in JEA's CFB Boilers
Atmospheric Fluidised Bed Combustion (AFBC) The bubbling type AFBC boiler offers efficient, cost-effective, reliable and viable alternative to conventional solid fuel-fired boilers for industrial applications. With over 280 installations across the world, the boiler offers benefits like fuel flexibility, high efficiency, low emissions, and
Reducing Ash Agglomeration in JEA's CFB Boilers
The ash from the fluidised bed, cyclone and ESP is conveyed pneumatically to the main ash silo, keeping the plant clean of ash. The boiler is designed for fluidising velocities up to 4.5 m/s, generating high turbulence and resulting in good mixing of hot bed material with fuel and recirculated fly ash. The height of the bed is
The ash from the fluidiesd bed, the cyclone and the ESP is conveyed pneumatically to the main ash silo, keeping the plant clean of ash. The boiler is designed with fluidising velocities up to 4.5m/s, generating a high turbulence and resulting in a good mixing of hot bed material with fuel and recirculated fly ash. The height of the bed is kept
An integrated fluidized bed ash cooler for a fluidized bed boiler, particularly a circulating fluidized bed (CFB) boiler, employs at least two fluidized bed sections positioned in series along a solids flow path. Each section contains fluidizing means, the first section along the solids path being separated from a following section with a

plant bobbling bed boiler is used .the chapter feature of bobbling bed boiler, in that fluidized bed combustion play vital role. In plant Circulating Fluidized Bed Combustion (CFBC) is in use it process and also advantages mentioned . The greatest variation in the …
and a fluidized bed ash cooler (FBAC). The furnace (aspect ratio of more than 2 : 1), especially, is designed to fire an in-digenous Korean fuel that is low grade and reactivity anthra-cite, which is different from other CFBCs using subbituminous coal [Maitland and Schaker, 1997]. In this study, the Tonghae CFBC was simulated to predict
May 05, 2020 · The fluidized bed ash cooler is favored by its large heat transfer coefficient (HTC), strong cooling capacity and large output, and thus it was adopted by most of the early large-scale fluidized bed boilers in China. The performance of the fluidized bed ash cooler highly depends on the fluidization quality. This requires that the particle size
For a bed burning bituminous coal, the carbon content of the bed is only 1%, while the rest of the bed is made up of ash, together with sand and/or lime and calcium sulphate. Because of the small particle size and recycling of solids back to the combustor, the CFBC boiler is able to achieve a combustion efficiency over 98% and a Ca/S ratio of 2.5 for 90% sulfur capture ( Figure 5.11 ).
Circulating Fluidized bed Combustion (CFBC) boiler. The fluid bed temperature was taken in the range of 800-950 degree centigrade. The proximate and ultimate analysis data were obtained. Based on the heat loss or indirect method the boiler efficiency was estimated and maximum heat loss was due to moisture content in the fuel..
