Design and commissioning of a 1MW pilot-scale oxy-fuel

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

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

Simulation of the 200 MWe Tonghae Thermal Power Plant

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

Design and operation of the double-cylinder rotary ash

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

Recovery of alumina from circulating fluidized bed

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 ).
