Circulating fluidised beds operate with relatively high gas velocities and fine particle sizes.
abc Uniform temperature distribution in the bed along with the agitating characteristic of the fluid bed provide optimum combustion, resulting in a minimum of unburnt fuel, reduced carbon monoxide emissions and improved efficiency. The term circulating bed is often used to include fluidised bed systems containing multiple conventional bubbling beds between which bed material is exchanged. Circulating difference between afbc and cfbc boiler combustion CFBC boiler technology offers high reliability and availability coupled with low maintenance costs, and complies with stringent emission regulations.
Bubbling fluidised bed combustion BFBC has dfiference defined height of bed material and operates at or near atmospheric pressure in the furnace. In circulating fluidised bed combustion CFBC system, bed is operated at higher pressure leading to high heat transfer, higher combustion efficiency, and better fuel feed.
Reduced Erosion of heat transfer surface in combustion chamber as surface is parallel to the flow contrary to AFBC. Xifference Bahamas, the biomass can be burned using conventional combustion technology like grate furnace or fluidized bed boilers.
In fluidised combustion, as ash is removed some unburned carbon is also removed resulting in lower efficiency. These AFBC boilers are difference between afbc and cfbc boiler with no moving parts in the combustor, which ensures diference maintenance costs. Atmospheric fluidised-bed combustion AFBC boilers offer efficient, cost effective and reliable steam generation.
AFBC and CFBC Boilers operation manuals
AFBC difference between afbc and cfbc boiler promises to provide a viable alternative to conventional coal-fired boilers and other solid fuel-fired boilers. Pressurised fluidised bed combustion PFBC system operates the bed crbc elevated pressure.
The typical capacity range for biomass power plants MW. The maintenance of steady state conditions in a fast fluidised bed requires the continuous recycle of particles removed by the gas stream circulating bed.
AFBC Boiler VS CFBC Boiler
The gas flows thorugh bed without disturbing particles significantly but gas velocity is high enough to support the total weight of bed fluidisation. Better for low garde Fuel with Low calorific value and high Ash content h. We have over 70 difference between afbc and cfbc boiler experience of boiler and autoclave, and we have a professional installation and after-sales staff for products.
Better Space utilization for large Industrial units b. At slightly higher velocity excess gas passes through the bed as betwesn fluidised bed and gives the bed the appearance of a boiling liquid. Better temperature Control f.
ZG CFBC boilers are capable of burning a wide range of fuels allowing for less expensive fuel preparation and thus a reduction in costs. Better SO2 capture d. Steam produces by the boiler will then drive a steam turbine generator to generate electricity.
Exhaust gases have sufficient energy to power a gas turbine, of course, gases need to be cleaned.
Newer Post Older Post Home. This CFBC technology differeence you to:. For power generation the biomass would be charged to the furnace of a steam boiler.
Better Techniques for Nox Ad e. Posted by Engineering Raju at Atmospheric Fluidised Bed Combustion Boiler. AFBC Atmospheric fluidised bed combustion process consists of forming a bed of inert materials like difference between afbc and cfbc boiler sized ash or ash mixed with sand, limestone for sulphur removaland solid fuel particles in a combustor and fluidising it by forcing combustion air up through the bed mixture.
