Wood Poles and Timber CFB Boiler in Tanzania
As a clean coal combustion technology, the Circulating Fluidized Bed (CFB) technology has been successfully used in boilers in Tanzania. The various types of solid fuel combustion systems historically available, such as wood poles and timber fired boilers have distinct and specific advantages and disadvantages.
A few disadvantages of wood poles and timber fired boilers are common to each of them in varying degrees are: Low residence time of material in the combustion zone (except stokers) requires high combustion temperatures to assure adequate combustion efficiency without excessive unburned carbon losses. High temperatures, usually more than 980°C, contribute to the formation of nitrogen oxides, which are environmentally objectionable. High combustion temperatures also dictate the use of post-combustion treatment scrubbers for removal of sulphur dioxide (SO2). When the combustion temperature is maintained between 815°C and 870°C, SO2 removal can be accomplished by injecting limestone (CaCO3) directly into the furnace.
The low ash fusion temperature of many solid fuels prevents use with conventional combustion systems because the higher combustion temperatures result in the formation of slag on boiler heat transfer surfaces. The need to overcome these difficulties when using lowgrade, less expensive fuels has led to the development of fluidized bed combustion systems. Presently, there are two distinct types of fluidized bed boilers in commercial operation: bubbling bed and circulating bed.
The need to improve the wood poles and timber fired boilers fluidized bed combustion efficiency and to burn a much wider range of fuels has led to the development and application of the circulating fluidized bed (CFB) boiler. Limestone is used as sulphur sorbent and furnace temperature is maintained in the range of 815°C to 925°C by suitable heat absorbing surface. Advantages associated with CFB include fuel flexibility – The relatively low furnace temperatures are below the ash softening temperature for nearly all fuels. As a result, the furnace design is independent of ash characteristics, which allows a given furnace to handle a wide range of fuels. Low SO2 emissions (95% removal) due to the use of limestone; low NOX Emissions; high combustion even with difficult-to-burn fuels. The unburned carbon loss component of the combustion efficiency is typically in the 1% to 2% range.
