Supercritical and ultrasupercritical coal-fired power

Although SC/USC is a mature technology, the majority of existing coal-fired power plants worldwide are still using subcritical technology. The barriers to the diffusion of SC/USC technologies are not technical but largely economic and regulatory. First, the long lifetime of coal-fired power plants slows fleet turnover.

Practice on Ultra-low Emission and Energy Efficient

It is in this way that coal-fired plants could better meet the increasingly stringent requirements on emissions (such as heavy mental, NH 3 and PM 2.5) while reducing energy and material consumption at the same time. The successful practice of ultra-low emission retrofit in Sanhe could serve as the reference for other coal-fired power plants.

Co-firing biomass with coal for power generation - EE

Co-firing biomass also has the potential to reduce CO 2 emissions, as biomass can replace 20 to 50% of coal, but a high percentage of biomass co-firing may reduce efficiency and power output. The net reduction of CO 2 emissions and other pollutants depends to a high degree on the biomass feedstock's origin and supply chain [3].. At present, some 230 combined heat and power (CHP) plants use
