"At present, ultra-supercritical power generation technology has three development directions: a new generation of high-efficiency primary reheat technology, secondary reheating technology, and larger single-unit capacity (120~1.
3 million kilowatts)
.
" Feng Deming, vice president of Southwest Electric Power Design Institute, said
at the "Ultra-supercritical Unit Technology Exchange 2013 Annual Conference" sponsored by the China Power Engineering Society and undertaken by China Power Science and Technology Network.
Wei Yupu, CEO of China Power Science and Technology Network, believes that "larger stand-alone capacity" as an overall direction in the future is a comprehensive trend in the development of
ultra-supercritical power generation technology.
At present, a new generation of high-efficiency primary reheat technology and secondary reheating technology can be described as two technical routes
for ultra-supercritical power generation.

"One heat at a time" upgrades to a "new generation"
The use of reheat cycles has become a necessary measure
to improve the thermal efficiency of large units.
From the existing generator sets in the world, the reheating method is divided into two types
: primary reheat and secondary reheating.

of 'a new generation of million-kilowatt high-efficiency primary reheating unit' for the first time.
" The new generation is compared with the ultra-supercritical units that have been put into operation in China

According to Feng Deming, after in-depth comparative research, it is found that the overall economy of the whole life of the new generation of million-kilowatt high-efficiency primary reheat unit and the million-kilowatt secondary reheat unit scheme is comparable

Although the former has slightly inferior power supply coal consumption index, it has less technical risk, more economical investment, better adaptability to variable load regulation, and its net thermal efficiency is at the same level
as the most advanced units under construction in Europe.

The successful research and development of "ultra-supercritical boiler with parameters above 700 degrees Celsius with secondary reheating" technology has broken the gap
that there is currently no ultra-supercritical secondary reheating unit in China.
It is understood that the coal consumption of the million kilowatt ultra-supercritical secondary reheating unit using this technology is about 272 g/kWh, which is about 12 g/kWh lower than that of the million kilowatt ultra-supercritical primary reheating unit, and each unit can save 72,000 tons of standard coal per year and directly reduce nearly 200,000 tons of carbon dioxide per year, which has good economic and environmental protection benefits
