Fuel flexible utility scale CFB boiler development

Summary:The increasing use of wood and biomass, notably in co-firing applications in Europe. We see a lot of wood-fired units that are going into Europe and certain countries. People are looking to burn biomass and this would favor fluid bed boilers, because you can't pulverize wood easily. If you're looking at fuel flexibility, like firing wood in combination with coal, CFB is sometimes the best and one of the only choices.

China CFB technology has been typically associated with small-scale industrial boilers using difficult fuels. But with the emergence of utility-scale commercial installations, ZG CFB boiler finds that this is changing.
Given the multi-decade lifespan of the average power generating asset, security of fuel supply is a key issue for the industry. However, it is becoming increasingly evident that, as ever, flexibility is the name of the game in the modern energy environment. A number of factors, such as the changing characteristics and availability of fuels and the increasing opportunities available from generating energy from waste streams, has prompted the development of fuel-flexible technologies, in particular Circulating Fluidized Bed (CFB) boilers.

CFB technology has evolved over the last four decades or so from industrial boiler technology used to burn difficult fuels in the late 1970s to a utility-scale product supplied by a growing number of major OEMs. We do see CFB as a more favorable product for burning multiple fuels like biomass and pet-coke, either in combination with coal or alone. We see a lot more of the market moving towards renewable fuels like biomass, or projects like pet-coke, or lower-value coal. The lower-value coal is easier to com-bust with a CFB than with PC: the coal would burn too hot in PC firing so you have slagging issues in those. In a controlled environment like a CFB these lower-value fuels are more suitable. Turkey and sub-Saharan Africa as examples of the increasing use of domestic low-quality coals: "We are seeing more countries looking to utilize their lower-value coals, when they can utilize local coals, rather than importing."

The increasing use of wood and biomass, notably in co-firing applications in Europe. We see a lot of wood-fired units that are going into Europe and certain countries. People are looking to burn biomass and this would favor fluid bed boilers, because you can't pulverize wood easily. If you're looking at fuel flexibility, like firing wood in combination with coal, CFB is sometimes the best and one of the only choices.

Within a internal CFB boiler the circulating bed material flows through the furnace together with the fuel and air. Combustion gases are then separated from the solid material with cyclones and any solids are returned to the lower part of the furnace while the gases pass on through the boiler.
One of the key differences between PF and CFB technologies is the boiler transit time. In a PF system a particle of fuel must reach a high enough temperature and be supplied with sufficient oxygen for complete combustion in a transit time of perhaps three or four seconds. In a CFB any unburned material is returned to the furnace and a larger particle can spend as much as 30 minutes within the furnace for complete combustion to occur.

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.
