circulating fluidized bed 1

Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc. BASIC DESIGN OF CIRCULATING FLUIDIZED BED BOILER 8 FEBRUARY 2012 Pichai Chaibamrung Asset Optimization EngineerReliability Maintenance Asset Optimization Section Energy Division Thai Kraft Paper Industry Co. A 2nd generation pressurized fluidized bed combustor uses circulating fluidized-bed technology and a number of efficiency enhancement measures.

circulating fluidized bed 2A pressurized circulating fluidized bed combustion (PCFBC) demonstration unit was planned, and there have been a number of pilot-scale investigations. Coal is used as fuel for almost forty percent of power generation worldwide (IEA, 2010). This role is set to continue in the foreseeable future. Figure 1 presents the global coal-fired capacity and the age distribution of the units, while Figure 2 presents the age and size distribution of the units (Platts, 2011). Amec Foster Wheeler has been the market leader for circulating fluidized bed steam generator technology supplying over 440 CFBs globally with an equivalent power capacity of 34 GWe.

Outotec Circulating Fluidized Bed technology applications include the Outotec CFB Boiler and the Outotec CFB Gasifier. The circulating fluidized bed reactor has unique qualities which differentiate it from other gas-solid contactors and make it promising for a wide range of reactions. This paper presents the results from biomass gasification tests in a pilot-scale (6.5-m tall 0.1-m diameter) air-blown circulating fluidized bed gasifier, an.

circulating fluidized bed 3Hydrodynamics plays a crucial role in defining the performance of circulating fluidized beds (CFB). The numerical simulation of CFBs is very important in the pr. This volume focuses on the present status of circulating fluidized bed technology and provides design information not available elsewhere. Areas covered include combustion of fossil fuel, hydrodynamics, combustion and environmental pollution, design and operating experiences, heat transfer and hydrodynamics, and process applications. Circulating fluidized bed technology removes the impurities from coal. Since sulfur and nitrogen oxides are not formed when burning this coal, the process is clean.
