Prediction of Slag Occurrence in a Lignite-Fired Utility Boiler
Lignite from Mae Moh mine is the largest source of solid fuel for electricity generation in Thailand. It is used in pulverized coal-fired boilers of a 2400 MW thermal power plant. Its high CaO content in ash is a major concern that can affect severe slagging. In this paper, potential of slag occurrence in the power plant was investigated by numerical simulation. The FactSage thermochemical pack...
متن کاملImprovement of Efficiency of Coal-Fired Steam Power Plant by Reducing Heat Rejection Temperature at Condenser Using Kalina Cycle
This paper proposes an approach for improving the plant efficiency by reducing the heat rejection temperature of power cycle using Kalina Cycle System 11 (KCS11) which is integrated at the steam condenser of a 500 MWe SubC (subcritical) coal-fired power plant. It is modelled by using power plant simulation software ‘Cycle Tempo’ at different plant operating conditions. Results show t...
متن کاملEnvironmental Impact of Heavy Metals Contained in Fly Ash Emitted from the Thai Lignite-fired Power Plant
In this work, the highly hazardous heavy metals (HM) are the focus of an assessment of the environmental impact of the Mae Moh Power Plant (Northem Thailand) fired with Thai lignites. The synergetic environmental impacts associated with the high sulfur content in the fuel (average value of 3.3% and maximum up to 7.0%) and the presence of a large number of heavy metals (As, Ba, Ce, Co, Cr, CS, N...
متن کاملSupercritical Water as Nanomedium for Gasification of Lignite-Water Suspension
The gasification of an aqueous suspension of lignite from Alexandria coalfield (Ukraine) under the supercritical pressure was studied. The initial rates of the formation of hydrogen, carbon dioxide and methane were evaluated. The mutually stimulating interaction of the components of "brown coal-water-mineral matter" system was shown due to the influence of nanoscaled water medium on the formati...
متن کاملTechnical Analysis of Conversion of A Steam Power Plant to Combined Cycle, Using Two Types of Heavy Duty Gas Turbines
Due to long life of steam power plants in Iran, transformation of steam cycles to combined cycles is under consideration. Bandar-Abbas steam power plant with capacity of 320 MW has been analyzed in this work. This old plant is located near the harbor city of Bandar-Abbas at southern Iran. Method of exergy analysis is used to study the current and the repowered systems. Optimum state of the repo...
