If there is less headspace under the boiler, then a mechanical dry bottom ash handling system is more suitable as it requires no water but still offers continuous ash removal, otherwise pneumatic ash handling may be used to convey ash out into an ash storage silo for interim holding prior to load out for disposal or reuse.FBC is atmospheric ...
In 2007, the United States produced over 131 million tons of coal combustion products from the nation's 1,308 coal-fired power plants. This 131 million tons of residuals must go somewhere, and has to be handled in a precise, controlled manner – especially ever since the EPA, under the Obama administration, began to tighten …
Ash handling processes. In ash handling systems, different processes are used – hydraulic, pneumatic and mechanical. In a hydraulic system, typically used in large thermal power plants, ash from the furnace grate falls into a system of water, travelling at high pressure, and is then carried to sumps.
