The results of laboratory studies carried out to identify the possibility and effectiveness technologies for complex recycling components flue gases wastewater from thermal power plants industrial boilers are presented. following factors were investigated: degree saturation water solutions with CO2, efficiency using these regeneration cation exchangers, properties intended exchange filters prep...

In the work under consideration, using an experimental stand formed by a cylindrical coil, modes of air movement through flue ramjet steam boiler were investigated. Experimental studies have revealed shortcomings in operation direct-flow and proposed ways to increase heat transfer turbulizing gas-air flow convective part flue. The Ansys programmable engineering environment was used simulate exc...

In development of Expert Systems (ES), it important to acquire knowledge from multiple human experts. Cooperative Distributed ES (CDES) is a framework which can unify multiple expertise to develop a large scaled ES. In CDES, ESs which are in the process of building through acquiring knowledge from human experts coorsspond to agents, and task structure is learned by cooperation among agents base...

The capturing of CO2 from power plant flue gases offers unique chance to alleviate the emissions coal-fired plants environment. fraction captured and increased production that results loss in whole efficiency are determinant factors for net reduction atmosphere via carbon dioxide capture storage. Post-combustion is great interest as it easy implement existing plants. use post combustion was rev...

This report is in two sections: the first describes the flue gas and its treatment in post-combustion capture and the second covers the flue gas in oxyfuel combustion capture. The main components of the flue gas in pulverised coal combustion for postcombustion capture are CO2, N2, O2 and H2O, and air pollutants such as SOx, NOx, particulates, HCl, HF, mercury as well as other contaminants. The ...

The aim of this work is to evaluate the characteristics of activated and non-activated carbon obtained from carbon-enriched coal fly ashes (CECFA) from two different power stations to be used in the low temperature reduction of NO from stack gases. Carbon-rich fractions were obtained by mechanical sieving of fly ashes and by oil agglomeration. Activation of some samples was carried out in steam...

In this work, theoretical rate constants are estimated for mercury oxidation reactions by hydrogen chloride that may occur in the flue gases of coal combustion. Rate constants are calculated using transition state theory at the quadratic configuration interaction (QCI) level of theory with single and double excitations, and are compared to results obtained from density functional theory, both i...

The tendency of alkaline (sodium, potassium and lithium) salts of taurine, β-alanine, sarcosine and L-proline to form precipitates under varying operational conditions of CO2 absorption has been investigated. CO2 absorption experiments have been performed at 293.15 and 313.15 K, at partial pressures relevant for capturing CO2 from flue gas conditions and amino acid salt concentrations up to the...
