Mapping and Prediction of Coal Workers’ Pneumoconiosis with Bioavailable Iron Content in the Bituminous Coals

Based on the first National Study of Coal Workers' Pneumoconiosis (CWP) and the U.S. Geological Survey database of coal quality, we show that the prevalence of CWP in seven coal mine regions correlates with levels of bioavailable iron (BAI) in the coals from that particular region (correlation coefficient r = 0.94, p < 0.0015). CWP prevalence is also correlated with contents of pyritic sulfur (...

Water/gas Permeability of Bituminous Mixtures and Involvement in Blistering Phenomenon

Moisture damage to bituminous pavement occurs via several mechanisms, and appears in diverse forms such as blistering, stripping, and disaggregation. Blistering is a fulminating phenomenon in which the trapped moisture evaporates and upheaves the pavement surface layer within a few hours as a result of so-called blistering heat. In contrast, stripping and disaggregation are types of internal ch...

Chemical Analysis of Drinking Water of Kashan District, Central Iran

The purpose of this study is investigating the chemical analysis of drinking water in Kashan district. This district contained Kashan, Aran and Bidgol and Nooshabad cities and it had an estimated population more than of 400,000 in 2007. 42 Samples were collected during October 2006 to May 2007.The temperature of the water Samples is in the range 25-30°C. The water samples were analyzed for pH ,...

Investigation of Fuel Cell System Performance and Operation: A Fuel Cell as a Practical Distributed Generator

Emissions and Furnace Gas Temperature for Electricity Generation via Co-firing of Coal and Biomass

The emissions of carbon dioxide and nitrogen and sulphur oxides for electricity generation with coal and biomass co-firing are investigated and the furnace gas temperature assessed. The study uses simulation and considers fuel combinations based on two coals (bituminous coal, lignite) and four types of biomass (rice husk, sawdust, chicken litter, refused derived fuel). With increasing biomass, ...
