These AFBC boilers are designed with no moving parts in the combustor, which ensures reduced maintenance costs.

Atmospheric fluidised-bed combustion AFBC boilers offer efficient, cost difference between afbc and cfbc boiler and reliable steam generation. Reduced Erosion of heat transfer surface in combustion chamber as surface is parallel to the flow contrary to AFBC. The gas flows thorugh bed without disturbing particles significantly but gas velocity is high enough to support the total weight of bed fluidisation.

The maintenance of steady state conditions in a fast fluidised bed requires the continuous recycle of particles removed by the gas stream circulating bed. ZG CFBC boilers are capable of burning a wide range of fuels allowing for less expensive fuel preparation and difference between afbc and cfbc boiler a reduction in costs.

Bubbling fluidised bed combustion BFBC has a defined height of bed material and operates at or near atmospheric pressure in the furnace. Atmospheric Difference between afbc and cfbc boiler Bed Combustion Boiler. Circulating fluidized-bed combustion CFBC boiler technology offers high reliability and availability coupled with low maintenance costs, and complies with stringent emission regulations.


The typical capacity range for biomass power plants MW. In Bahamas, the biomass can be burned using conventional combustion technology like grate furnace or fluidized bed boilers. AFBC Atmospheric fluidised bed combustion process consists of forming a bed of inert materials like finely 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.

Difference Between AFBC And CFBC Boilers–ZBG

Pressurised fluidised bed combustion PFBC system operates the bed at elevated pressure. Better Techniques for Nox Control e.

Steam produces by the boiler will then drive a steam turbine generator to generate electricity. Better Space qnd for large Industrial units b. We have over 70 years’ experience of boiler and autoclave, and we have a professional installation and after-sales staff for products. At slightly higher velocity excess gas passes through the bed as boildr fluidised bed and gives the bed the appearance of a boiling liquid.

Difference between afbc and cfbc boiler gases have sufficient energy to power a gas turbine, of course, gases need to be cleaned.

Last Drivers  MP2259 EPUB

For power generation the biomass would be charged to the furnace of a steam boiler. Better SO2 capture d. 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 boioer. Better temperature Control f.

AFBC Boiler VS CFBC Boiler

This CFBC technology helps you to:. In fluidised combustion, as ash is removed some unburned carbon is also removed resulting in lower efficiency.

betweem 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. AFBC technology promises to provide a viable alternative to conventional coal-fired boilers and other solid fuel-fired boilers.

AFBC Boiler VS CFBC Boiler

Newer Post Older Post Home. Circulating fluidised beds operate with relatively high gas velocities and fine particle sizes.

The term circulating bed is often used to include fluidised bed systems containing multiple conventional bubbling beds between which bed material is exchanged. Better for low garde Fuel with Low calorific value and high Ash content h.
