A Ten-Year Study on Alkali Content of Coal Fly Ash
نویسندگان
چکیده
After years of decline, coal consumption has risen significantly in the last year (2021), driven mainly by ever-increasing demand fast-growing Asian countries and fostered rising gas prices Europe United States. Coal is both largest electricity production source carbon dioxide emission. Coal-fired plants produce generating steam burning a boiler, but also large amounts fly ash. ash contains essential constituents for cement production, such as Ca, Si, Al, Fe. Application coal-fired to clinker at high doses may reduce limestone content raw mix. Furthermore, one industrial materials utilized development low-carbon cements concretes on account its chemical characteristics. The monitoring methodology based fundamentally analysis set variables (Na2Oe, Na2O, K2O, free CaO, reactive silica fineness) over time. Weak relations between Na2O Na2Oe, were found. This applied research been done verify previously research. scope this paper assess alkaline period 10 years. Na2O-equivalent ranged from 0.35% 2.53%, with an average value 0.79%. These values should be taken into producing made potentially aggregates order mitigate alkali–silica reaction (ASR).

Study on the Alkali Activated Fly Ash Mortar
The development of alkali-activated binders seems to present a greener alternative to OPC. The present study has been made on the low calcium fly ash with alkali activator as an alternative binding material as mortar. The mortar has been prepared with ennore sand and Indian fly ash mixed with alkali activator fluid consisting of sodium silicate and sodium hydroxide of different concentrations. ...
متن کاملAlkali Leaching of Indian Coal for Ash Reduction
Coal is a major source of energy. The available Indian coal quality is very poor having very high ash content and low calorific value. Indian coal generates a large quantity of ash as a by-product of combustion. The objectives of the present study were to reduce the ash content of coal to produce ultra-clean coal. The coal was treated wi...
متن کاملThe respiratory toxicity of coal fly ash
The aim of this study was to compare the relative respiratory toxicity of CFA samples obtained from three Chinese coal-burning power stations to CFA obtained from a UK coal-burning power station; both bulk and respirable PM10 samples were tested. In order to elucidate CFA toxicity, a multi-disciplinary approach was taken, thereby considering geochemical aspects of the fly ash as well as biochem...
متن کاملHealth aspects of coal fly ash
Employees of coal-fired power stations and people living nearby as well as those involved in the shipment and processing of coal fly ash can be exposed to coal fly ash (pulverised fuel ash or “PFA”). An extensive research program was carried out in order to map such exposure and its effects. Particle size distribution, chemical composition, quartz, radioactivity, emission factors and fugitive d...
