Bed Ash Cooler Working Principle

The air flow rate particle size of the solids and air distributor type are considered to be the key.

Bed ash cooler working principle. BASIC DESIGN OF CIRCULATING FLUIDIZED BED BOILER 8 FEBRUARY 2012 Pichai Chaibamrung Asset Optimization EngineerReliability Maintenance Asset Optimization Section Energy Division Thai Kraft Paper Industry CoLtd. The Working Principle of Fluid Bed Granulator A study of fluidized bed granulation process shows that the process is generally the same irrespective of the machine design. The performance of a fluidized bed ash cooler was studied using a cold experiment bench.

The next process after filtering and dehumidifying is heating. For a bed burning bituminous coal the carbon content of the bed is only 1 while the rest of the bed is made up of ash together with sand andor lime and calcium sulphate. A fluid bed dryer works on a principle of fluidization of the materials.

With over 280 installations across the world the boiler offers benefits like fuel flexibility high efficiency low emissions and. Its a most advanced and a very successful cooling technology. Bed is where the coal or fuel spreads.

This gas or air will move upwards through the spaces between the particles. Maintain drum level near upper limit 12. Atmospheric Fluidised Bed Combustion AFBC The bubbling type AFBC boiler offers efficient cost-effective reliable and viable alternative to conventional solid fuel-fired boilers for industrial applications.

Cool incoming air absorbs heat from the surface of heated pipes. In the fluidization process hot air or gas flow is introduced through the bed of solid particulates. Fluid bed technology is used for cooling heating and drying of bulk solids materials.

It draws air from the surroundings inside the AHU unit past the filters and into the heating chamber. The fluidised bed combustion FBC takes place at about 840C to 950C. A bed of solid particles is said to be fluidized when the pressurized fluid liquid or gas is passed through the medium and causes the solid particles to behave like a fluid under certain conditions.
