TH98490A - Methods and equipment for treating coal ash - Google Patents

Abstract

DC60 (25/02/51) to make effective use of coal ash while reducing mercury concentrations in Exhaust gas of cement kiln down The ash from the coal is obtained from the power plant by heat, or likewise, the coal ash is broken down into ashes and unburned carbon. The ashes will be extracted. Benefits in cement production equipment as raw materials for cement production And the unburned carbon that is isolated will It is utilized in cement production equipment according to the mercury concentration in the furnace exhaust gas. Cement of cement production equipment In the event that the mercury concentration in the gas from the furnace exhaust Cement of high cement production equipment Unburned carbon in coal ash with mercury content. High can be treated in equipment other than cement production equipment without feeding. Un-calcined carbon to cement production equipment Or the amount of unburned carbon As such, fed to cement production equipment may be optimized. It is possible to separate Mercury from unburned carbon that has been isolated And it utilizes the unburned carbon where mercury is then separated in cement-fueled production equipment. To make effective use of coal ash while reducing the mercury concentration in Seamet furnace exhaust gas down The ashes from the coal are obtained from the power plant by heat, or likewise, the ashes from the hungry coals are broken down into ashes and unburned carbon. The ashes will be extracted. Benefits in cement production equipment as raw materials for cement production And the unburned carbon that is isolated will It is utilized in cement production equipment according to the mercury concentration in the furnace exhaust gas. Cement of cement production equipment In the event that the mercury concentration in the gas from the furnace exhaust Cement of high cement production equipment Unburned carbon in coal ash with mercury content. High can be treated in equipment other than cement production equipment without feeding. Un-calcined carbon to cement production equipment Or the amount of unburned carbon As such, fed to cement production equipment may be optimized. It is possible to separate Mercury from unburned carbon that has been isolated And it utilizes the unburned carbon where mercury is then separated in cement-fueled equipment.
