An ash pond is a structure specially engineered for the wet disposal of bottom ash and fly ash. The size of a coal ash pond depends on the capacity and disposal needs of the power plant with some ponds covering as much as 1,500 acres. Ponds are filled with coal ash slurry and the water is allowed to drain and evaporate over time.
The coal water slurry boiler doesn’t need coal yard with little slag which needs small occupying area. The coal water slurry is stored in the storage tank and pumped through pipes, and there is no pollution as it does not produce dust and this also shows good environmental protection character.
Coal Water Slurry Boiler – Enneng Machinery. The coal water slurry boiler doesn’t need coal yard with little slag which needs small occupying area. The coal water slurry is stored in the storage tank and pumped through pipes, and there is no pollution as it does not produce dust and this also shows good environmental protection character.
Coal water slurry (CWS) is typically composed of 60–70% coal, 30–40% water, and 1% chemical additives. It has been developed over the last 20 years as an alternative to fuel oil mainly in industrial and utility boilers.
The resulting product (coal slurry) is then prepared for intermediate storage or transport. Large particle coal-water slurry fuel can be used to produce steam in boilers. Smaller (under 80 micrometer) particle coal-water slurry fuel can be used in diesel engines with or without co-fuels.
The slurry solids level is monitored to avoid slurry line plugging as well as excess water usage. Slurry barricades allow the deposited slurry to dewater via gravity. Water from this phase is collected in a mine pool then pumped to an aboveground thickener. The thickener settles excess solids while the water may be reclaimed as slurry makeup.
A method is disclosed for improving ignition time delay and carbon conversion efficiency in the combustion of coal water slurries wherein oxygen-enrichment of primary air is performed in the range of greater than 21% and up to 28%.
