Subcritical Coal Boiler

View of Supercritical and ultrasupercritical coal-fired

Source: Nalbandian, 2008: p. 8 SC and USC technologies achieve high efficiency and consequently use less coal and result in reduced CO 2 emissions. According to the IEA Clean Coal Center, CO 2 emissions may be reduced by 23% per unit of electricity generated by replacing existing subcritical plants with SC/USC technology (Nalbandian 2008). ). Specifically, a 1% increase in efficiency reduces

How much do ultra-supercritical coal plants reduce air

This means that a 1000 megawatt (MW) coal-fired plant using subcritical technology will need to burn coal at a thermal input rate of 1000 MW / 38 per cent = 2630 MW-thermal to generate its full output. This corresponds to 410 tonnes of coal per hour, assuming a typical calorific value of 5500kcal/kg, and 4100kg/h of SO2 in raw flue gas.
