We have over 70 years’ experience beetween boiler and autoclave, and we have a professional installation and after-sales staff for products. 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. Posted by Engineering Raju at Atmospheric fluidised-bed combustion AFBC difference between afbc and cfbc boiler offer efficient, cost effective and reliable steam generation.

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.

What is the Difference Between AFBC and CFBC Boiler,CFBC boiler manufacturer-ZBG Boiler

The term circulating bed is often used to include fluidised bed systems containing multiple betweeen bubbling beds between which bed material is exchanged.

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 fluidised bed and gives the bed the appearance of a boiling liquid. Atmospheric Fluidised Bed Combustion Boiler.

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

AFBC Boiler VS CFBC Boiler

Better Space utilization for large Industrial units b. In fluidised combustion, as ash is removed some unburned carbon is also removed resulting in lower efficiency. Better temperature Control f.

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

Better for low garde Fuel with Low calorific value and high Ash content h. AFBC technology promises to provide a viable alternative to conventional coal-fired boilers and other solid fuel-fired boilers.

What is the Difference Between AFBC and CFBC Boiler

Exhaust gases have sufficient energy to power a gas turbine, of course, gases need to be cleaned. The gas differencd thorugh bed diffeence disturbing particles significantly but gas velocity is high enough to support the total weight of difference between afbc and cfbc boiler fluidisation. Steam produces by the boiler will then drive a steam turbine generator to generate electricity. The maintenance of steady state conditions in a fast fluidised bed requires the continuous recycle of particles removed by the gas stream circulating bed.

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

AFBC and CFBC Boilers operation manuals

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

The typical capacity range for biomass power plants MW. ZG CFBC boilers are capable of burning a wide range of difference between afbc and cfbc boiler allowing for less expensive fuel preparation and thus a reduction in costs. Uniform temperature distribution in the bed voiler with the agitating characteristic of the fluid bed provide optimum combustion, resulting in a ddifference of unburnt fuel, reduced carbon monoxide emissions and improved efficiency.

Reduced Erosion of heat transfer surface in combustion chamber as difference between afbc and cfbc boiler is parallel to the flow contrary to AFBC.

Circulating fluidised beds operate with relatively high gas velocities and fine particle sizes. This CFBC technology helps you to:.
