A survey into the respiratory effects of prolonged exposure to pulverised fuel ash.
Previous studies of respiratory disorders in workers exposed to pulverised fuel ash (PFA) have been confined to radiological effects that were found to be minimal. The present survey included 268 men (88% of the defined population) with a history of more than 10 years exposure to PFA in six power stations in the south east of England. Respiratory questionnaires with full occupational histories ...
متن کاملUtilization of Ash as a Structural Fill in Low-lying Areas
Thermal power stations using pulverised coal as fuel, generate large quantity of ash as waste by product, which poses dual problem of environment and disposal. Flyash is a versatile material with many possible applications such as land filling and in land reclamation of low lying areas. An experimental investigation has been carried out to study the behaviour of compacted ash overlying sand dep...
متن کاملThe Performance of Fly Ash as Fill Material for Embankment Model on Soft Soil
Fly ash is one of coal ashes resulted from power plants using coal to generate electricity. As a result of large utilization of coal, large volumes of coal ash produced as waste material. Direct use of these materials in construction projects, not only provides a promising solution to the disposal problem, but also as an alternative for structural fills material. High shear strength, low compre...
متن کاملEffect of Pressure on Ash Formation during Pulverised Coal Combustion and Gasification
In this paper, effects of the operating pressure on ash formation reported in the open literature have been reviewed. In particular, the recent significant advances achieved at the Cooperative Research Centre for Coal in Sustainable Development (CCSD) in Australia are highlighted. The operating pressure significantly influences the size and the chemistry of ash generated through its effects on ...
متن کاملExtraction of Vanadium Oxide from Boiler Fuel Ash
Fuel oil used in power plants contain metal impurities like Vanadium. After combustion, this metal remains in boiler fuel ash in the form of oxide. In this research, extraction of Vanadium oxide from fuel ash has been investigated. Two processes were used for this purpose. A pyro- hydrometallurgy and a hydrometallurgy process. In the pyro-hydrometallurgy process, using sodium carbonate, salt ro...
