moisture) is blown into the boiler and combusted by supporting it in air rather than on fixed grates. Rapid changes in combustion rate and, therefore, steam generation rate are possible because the finely divided fuel particles burn very quickly. A later innovation in wood firing is the fluidized bed combustion (FBC) boiler. A fluidized bed
The NISCO Cogeneration facility utilizes two fluidized bed boilers to generate 200 MW of electricity and up to 80,000 LBS/HR of steam for process use. The partnership, of three industrial electricity users, Citgo, Conoco, and Vista Chemical, and the local utility, Gulf States utilities, was formed in the late 1980's.
It was concluded from this study that particle development in a fluidized bed black liquor steam reformer is a complex combination of mechanisms and submechanisms that simultaneously participate in bed particle evolution. Coating and attrition seem to be the most significant mechanisms, followed by agglomeration which results from poorly
In Bahamas, the biomass can be burned using conventional combustion technology like grate furnace or fluidized bed boilers. For power generation the biomass would be charged to the furnace of a steam boiler.Steam produces by the boiler will then drive a steam turbine generator to generate electricity.
