2. DOLOMITE DESULFURIZATION BEHAVIOR IN A BUBBLING FLUIDIZED BED PILOT PLANT FOR HIGH ASH COAL
Abstract Although fluidized bed in situ desulphurization from coal combustion has been widely studied, there are aspects that remain under investigation. Additionally, few publications address Brazilian coal desulphurization via fluidized beds. This study used a 250 kWth bubbling fluidized bed pilot plant to analyze different aspects of the dolomite desulphu

3. Corrosiveness of Brazilian Candiota Coal
ABSTRACT Candiota city, in the south of Brazil, is located near the largest reserves of mineral coal of the country. This coal is used for thermoelectric power generation. The extraction of coal from open-cut mines involves operations may generate at least some particulate matter into the atmosphere. These particles retained on the surface of metallic struct

5. Processamento e caracterizaÃÃo de peÃas cerÃmicas obtidas a apartir do resÃduo do granito asa branca com adiÃÃo de produtos da combustÃo do carvÃo mineral / Processing and characterization of ceramic parts gotten to apartir of the residue of the granite white wing with addition of products of the combustion of the mineral coal
Durante a queima do carvÃo mineral sÃo gerados vÃrios tipos de resÃduos ou subprodutos (produtos da combustÃo do carvÃo, ou PCCs). Esses produtos incluem as cinzas volantes, as cinzas pesadas ou de fundo, a escÃria da caldeira, e o gesso do FGD - Flue Gas Desulfurization.Embora alguns PCCs sejam reutilizados como matÃria-prima para a construÃÃo civ

6. Past exposure to asbestos and combustion products and incidence of cancer among Finnish locomotive drivers.
Locomotive drivers in the steam engine era were exposed to asbestos during their vocational training for two years while training in workshops. Later in their career they had exposure to coal and diesel combustion products. To assess the level of earlier exposure historical working conditions were reconstructed and hygienic conditions were measured. The aver
