Hot cyclones separate the circulating bed material from the flue gas stream leaving the furnace at around DegC. The solid particles separated from the flue gas are re-circulated back into the furnace through the loop seal. A vortex finder is provided to enhance the separation efficiency of the hot cyclone. The flue gas containing the fine ash particles exits the cyclones through the vortex finder and outlet flue.
The entire hot cyclone, loop seal and outlet flue assembly is provided with a multi layer refractory lining.
The design and arrangement of the hot cyclone is based on specific sizing criteria that are a function of the actual gas velocities entering and leaving the cyclone.
Fast to respond to load changes. The CFB, with its low combustion temperature is an especially good solution for coals with low ash fusion temperatures, Preventing the formation of slag. High Combustion Efficiency The continuous circulation of solids through the EnmasGB CFB system keeps the fuel in an ideal combustion environment for a long period of time.
The long residence time results in very efficient fuel combustion, while minimising process changes resulting from sudden changes in fuel quality or mixes. Better sulphur capture with less limestone and improved heat transfer.
The ratio between operating gas velocity and minimum solids entrainment velocity allow turndown ratios as high.
Operation over a wide range of boiler loads is possible without starting and stopping burners and auxiliary equipment. This is due to the combination of low combustion temperature and staged combustion. Elimination of Slagging The low combustion temperature of — DegC in EnmasGB CFB technology eliminates slag formation in the furnace and reduces the volatilisation of alkali salts. Operating at such low temperatures also means boiler corrosion and convective surface fouling is reduced. Furnace Erosion Potential The maximum velocity of flue gas across various zones is fixed at an optimum level.
Considering low temperature staged combustion associated with the CFBC, the ash particle shape and structure do not reach the level of creating adverse implications in this velocity range. Elimination of hundreds of opening for the arrangement of heating surfaces and in turn the access and inspection openings No horizontal elements need to be arranged in the furnace across the gas flow carrying higher solid density.
Redundancy In the absence of rotating type of equipments, complicated fuel pipes etc. High reliability CFB boilers have demonstrated a high availability due to the simple proven design as offered now. As a result, we are sure to provide excellent performance results and high reliability. Environmental Aspect We have the ability to provide equipments that consistently meet strict environmental requirements.
This is proved based on the number of operators required for a CFB plant. The reliability is excellent which is why many industrial customers select CFB, for their power plants. The parameters to be monitored in CFB are less.
Circulating Fluidised Bed Combustion Boiler (CFBC)
This is illustrated in figure Photo 24 show real life examples. Fin filler plates are to be properly placed in plane. The welds should be of full penetration welds and the excess beads are to be ground off. Panel fins which are slit for alignment purpose are to be sealed with full penetration welds. The beads are to be ground flush afterwards.
