Posted by Engineering Raju at In Bahamas, the biomass can be burned using conventional combustion technology like grate furnace or diffrrence bed boilers. The gas flows thorugh bed without disturbing particles significantly but gas velocity is high enough to support the total weight of bed fluidisation.

Better Space utilization for large Industrial units b. 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.

AFBC and CFBC Boilers operation manuals

The typical capacity range for biomass power plants MW. The maintenance of steady state conditions in a fast fluidised bed requires the difference between afbc and cfbc boiler recycle of particles removed by the gas stream circulating bed. Exhaust gases have sufficient energy to power a gas turbine, of course, gases need to be cleaned.

Bubbling fluidised bed combustion BFBC has a defined height of bed material and operates at or near atmospheric pressure in the furnace.

This CFBC technology helps you to:. Newer Post Older Post Home.

Difference Between AFBC And CFBC Boilers–ZBG

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. In fluidised combustion, as ash is removed some unburned carbon is also removed resulting in difference between afbc and cfbc boiler efficiency. Circulating fluidized-bed combustion CFBC boiler technology offers high reliability and availability coupled with low maintenance costs, and complies with stringent emission regulations.

The term circulating bed is often used to include fluidised bed systems containing multiple conventional bubbling beds between which bed material is exchanged. Better temperature Control f.

AFBC Boiler VS CFBC Boiler

Atmospheric fluidised-bed combustion AFBC boilers offer efficient, cost effective and reliable steam generation. 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.

Reduced Erosion of heat transfer surface in combustion chamber as surface difference between afbc and cfbc boiler parallel to the flow contrary to AFBC. At slightly higher velocity excess gas passes through the bed as bubbles fluidised bed and gives the bed the appearance of a boiling liquid. Steam produces beween the boiler will then drive a steam turbine generator to generate electricity.

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.

ZG CFBC boilers are capable of burning differejce wide range of fuels allowing for less expensive fuel preparation and thus a reduction in costs. Pressurised fluidised bed combustion PFBC system operates the bed at elevated pressure.

Better SO2 capture d. Circulating fluidised beds operate with relatively high gas velocities and fine particle sizes. Better Techniques for Nox Control e. Atmospheric Fluidised Bed Combustion Boiler. AFBC technology promises to provide a viable alternative to conventional coal-fired boilers and other solid fuel-fired boilers.

These AFBC boilers are designed with no moving difference between afbc and cfbc boiler in the combustor, which ensures reduced maintenance costs.

We difgerence over 70 years’ experience of boiler and autoclave, and we have a professional installation and after-sales staff for products.
