Boiler ash down conveyor belting. fluimac systems basic concept is to extract the hot ash continuously from the fbc boiler with the superbelt steel belt conveyor the ash is cooled with ambient air that flows through the belt openings and through the ash bed laying on it obtaining a regime of fixed bed heat exchange the main characteristics of
Processbarron bottom ash submerged drag conveyors feature special water-tight bearings and heavy duty welded chains that reduce stretching common with dual strand submerged conveyors. the submerged ash conveyor systems provide an air tight seal while still allowing ash and other materials to be removed from the boiler or furnace system.
The magaldi ecobelt174 bio is a system for dry extraction, cooling and conveying of bottom ash produced by grate boilers burning biomass e.g. wood, bark, straw, bagasse, rice hulls, peach pits, almond shells, orchard pruning, coffee grounds. depending on the boiler lay-out and restrictions, the same system can also be used to convey grate siftings and fly ash from the hoppers located under the second and third
For big coal fired units there are basically two types of boilers pulverized coal fired pc boilers and fluidized bed type boilers. bottom ash slag handling for pc units. in most of the pc units the bottom ash is removed by under-water submerged scraper conveyor scc and crushed below 100 mm. scc amp crusher is normally part of the boiler supplier.
Processbarrons typical ash conveyor design incorporates a single strand chain made of high strength drop forged crmn steel. the fly ash conveyors forged links are heat treated to a surface hardness of 5964 hrc to a depth of 0.7mm. processbarron can also provide custom metallurgies and stainless steel conveyors for use in highly corrosive environments.

Hot ash slag and clinkers falling from the boiler through a transition chute to the water-filled trough. the transition chute provides an air-tight seal between the boiler and the conveyor. the water quenches and cools the hot ash and slag, shattering some of the large clinkers as a result of thermal shock. the ash then settles to the bottom of the

Apr 03, 1984nbsp018332as seen in fig. 1, a conventional quenching vessel or trough 2 contains a bath 1 of water and is arranged to receive ash directly from the automatic ash unloader 3 of a large coal-fired boiler. a scraper-type chain conveyor 4 moves wet quenched ash up and out of the trough to a bricketting or storage operation.
In the normal course, the resultant clinker is small and falls down the funnel-shaped boiler bottom due to gravity, through a 6-8 inch opening in the bottom hopper. a steel conveyor belt which runs beneath the opening continuously removes the clinker, which is sprinkled with water to cool it, then crushed and moved out as ash slurry.
At full load, each boiler produces up to 540 t of coarse ash and 2 450 t of dry fly ash per day at 32 ash content. coarse ash is removed continuously from the hoppers at the bottom of each boiler by a submerged scraper conveyor of the drag link type.
The more volatile part, known as fly ash, is dragged along by the gasses and deposited in the bottom of ash hoppers in the equipment downstream of the boiler, such as economizers, air pre heater, duct hoppers, electrostatic precipitators, stack hoppers and is normally removed in pneumatic conveying system or hydraulic systems.
