Fly ash dryer
The prospect of fly ash drying
In the power plant of coal fired boiler system, the discharge of ash can be divided into two types of dry exhaust and wet exhaust. At present, in the cement industry developed regions, such as Jiangsu, Shandong, Zhejiang, Hebei and other place, dry fly ash is a mixing materials for cement production, the market is good, and has the short supply of power, and dry fly ash has became a kind of resource; wet fly ash are basically the same as dry fly ash in various physicochemical properties, just because of water (up to 45%), it cannot meet the requirements of cement production, and not affected by the market’s favor, so it can only be piled up in the wet library, and become more and more, and cause serious environmental pollution. With continuous optimization of industrial policy, and the laws and regulations of environmental protection is becoming more and more strict, wet fly properly processing has been put on the schedule. Only drying wet fly ash with reasonable energy consumption, simple process, to make the moisture low, so waste changes into treasure, and achieve double harvest of social and economic benefits. The widely used of fly ash dryer has solved the problem of pollution of fly ash and disposal problem, and can change coal ash from waste to treasure, and increase the economic income.
