Abstract
By installation of the latest model of fluidized bed boiler, the energy consumption efficiency is expected to become more than double. In Kyrgyz Republic, the boilers around 20 t/h are prevalent, and replacement demands of 9 cans are expected in the heat supply stations at four locations. Based on properties and varieties of coal, the Fluidized bed system would be suitable. The analysis of the coal-ash samples after combustion indicated that the unburned carbon in ash was 45% on average. Accordingly, the conversion of coal by combustion was determined to be 40%. The replacement of the existing 20 t/h boilers by fluidized bed boiler would reduce the CO2 emission of approximately 2,000 tons per year. Moreover, enhancing coal-fired heat supply station contributes to the prevention of the water related conflicts in the Aral Sea Basin area.
