Characteristics of distinct ash flows in a biomass thermal power plant with bubbling fluidised bed combustor
Characteristics of biomass used as fuel and distinct ash flows in a thermal power plant with BFBC (bubbling fluidised bed combustion) technology were studied. An integrated approach involving chemical composition, microscopy analysis, mineralogy, and thermal behaviour were used to characterize the ash. The ashes have a low unburned content, typically below 3 wt.% (dry basis), with higher values...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Determination of the Kinetic Parameters of Oxy-fuel Combustion of Coal with a High Ash Content
The aim of this study was to determine the kinetic parameters of the oxy-fuel combustion of char from a Brazilian bituminous coal with a high ash content. The char, with a particle diameter of 715 μm, was prepared in a N2 atmosphere at 1173 K. The oxy-fuel combustion assays were performed using a thermobalance at different temperatures and O2/CO2 gas mixtures of different concentrations. Accord...
متن کاملEffects of nitrogen content in fuel on NOX emissions under oxy-fuel coal combustion
Oxy-fuel coal combustion with flue gas re-circulation is known to be one of the most promising methods for reducing CO2 emissions from coal combustion power plants. In the oxy-fuel system, the combustion atmosphere consists of only O2 separated from air and flue gas re-circulated from a stack. Therefore, the flue gas is dominated by CO2 without any nitrogen gas. The most attractive potential as...
متن کاملReactions of SO3 with the O/H radical pool under combustion conditions.
The reactions of SO3 with H, O, and OH radicals have been investigated by ab initio calculations. For the SO3 + H reaction (1), the lowest energy pathway involves initial formation of HSO3 and rearrangement to HOSO2, followed by dissociation to OH + SO2. The reaction is fast, with k(1) = 8.4 x 10(9)T(1.22) exp(-13.9 kJ mol(-1)/RT) cm(3) mol(-1) s(-1) (700-2000 K). The SO3 + O --> SO2 + O2 react...
