Atmospheric fluidised-bed combustion AFBC boilers offer efficient, cost effective and reliable steam generation. Exhaust gases have sufficient energy to power a gas turbine, of course, gases need to be cleaned. Newer Post Older Post Home. The typical capacity range for biomass power plants MW.

Circulating fluidised beds operate with relatively high gas velocities and fine particle sizes. In fluidised combustion, as ash is removed some unburned carbon is also removed resulting in lower efficiency.

AFBC Boiler VS CFBC Boiler

Posted by Engineering Boildr at 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 Techniques for Nox Control e.

Pressurised fluidised bed combustion PFBC system operates the bed at elevated pressure. Circulating fluidized-bed combustion CFBC boiler technology difference between afbc and cfbc boiler high reliability boler availability coupled with low maintenance costs, and complies with stringent emission regulations.

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.

The maintenance of steady state conditions in a fast fluidised bed requires the continuous recycle of particles removed by djfference gas stream circulating bed. Better Space utilization for large Industrial units b. The gas flows thorugh bed without disturbing particles significantly but gas velocity is high enough to support the total weight of bed fluidisation.

Bubbling fluidised bed combustion BFBC has a defined difference between afbc and cfbc boiler of bed material and operates at or near atmospheric pressure in the furnace.

AFBC Boiler VS CFBC Boiler

Reduced Erosion of heat transfer surface in combustion chamber as surface is parallel to the flow contrary to AFBC. Better for low garde Fuel with Low calorific value and high Ash content h.

diference Better SO2 capture d. We have over 70 years’ experience of boiler and autoclave, and we have a professional installation and after-sales staff for products.

AFBC and CFBC Boilers operation manuals

In Bahamas, the biomass can be burned using conventional combustion technology like grate furnace or fluidized bed boilers. At slightly higher velocity excess gas passes through the bed as bubbles betwden bed and gives the bed the appearance of a boiling liquid. Better temperature Control f. AFBC technology promises difference between afbc and cfbc boiler provide a viable alternative to conventional coal-fired boilers and other cfvc fuel-fired boilers.

For power generation the biomass would be charged to the furnace of a steam boiler. 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. Steam produces by the boiler will then drive bboiler steam turbine generator to generate electricity. Atmospheric Fluidised Bed Combustion Boiler. This CFBC technology helps you to:.

These AFBC boilers are designed with no moving parts in the difference between afbc and cfbc boiler, which ensures reduced maintenance costs. The term circulating bed is often used to include fluidised bed systems containing multiple conventional bubbling beds between which bed material is exchanged.

Uniform temperature distribution in the bed along with the agitating characteristic netween the fluid bed provide optimum combustion, resulting in a minimum of unburnt fuel, reduced carbon monoxide emissions and improved efficiency.
