CFB boiler technology is a newest technology with Fuel flexibility,this CFB boiler technology can be used for industrial CFB boiler design and Power plant CFB steam boiler design.

Fuel flexibility characteristic for CFB boilers plays an important rule in industrial and utility size applications.Possibility to use wider range of fuels that has been long time considered as by-products or wastes and possibility to design boilers able to operate with alternative fuels is an important factor that improves fuel delivery security and plant economy.Presented article is based on similar publications that present Foster Wheeler's experience in design and delivery of the CFB boilers for wide range of coals and cofiring by-products of crude oil refining and coal processing. Aspects of biomass cofiring will be also presented.

A CFB boiler generates low levels of gaseous emissions without the use of additional flue gas cleaning equipment. The cost of flue gas desulfurization (FGD) and selective catalytic reduction (SCR) systems can be very significant. In addition, an SCR system requires ammonia injection, and the catalyst must be replaced on a regular basis. A CFB produces more ash, since in-furnace sulfur reduction is not as efficient as an FGD.On the other hand, limestone can be used directly and lime is not required. The cost of lime is typically several times higher than the cost of limestone. The end-product of a CFB is always dry and there are no wet discharge streams

Even though the CFB operates at a much lower temperature than a pulverized coal-fired unit,the high particle residence time and turbulent mixing provided by the hot circulating solids to enhance carbon burnout and in,practice,the two units operate with similar combustion efficiencies.The CFB,however,can operate with a lower flue gas exit temperature which enhances boiler efficiency. The reason for this lower flue gas temperature is the economizer, which can be used more effectively in a CFB.The water temperature can be raised in the economizer while still maintaining the appropriate steam/water ratio by weight in the furnace tubes, as the heat fluxes are lower than in a pulverized coal-fired unit.The SO2 content in CFB flue gas is also significantly lower than in a PC, since sulfur capture takes place in the furnace.This results in a lower acid dew point and flue gas can be colder without cold end corrosion.While more auxiliary power is needed for fluidization, no mills are required and there is no additional flue gas pressure drop due to FGD and SCR units, and no water consumption, as in a FGD.The power demand of these components are more or less equal to the power needed for fluidization.

Overall,CFB boiler technology offers so many advantages that it can be expected to be utilized more and more in future large-scale power generation,no matter for industry or power plant.

Biomass CFB Boiler Plant in Bahamas

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. The typical capacity range for biomass power plants 1-20MW.
