Supercritical PF is believed to be the most practical and feasible way to adjust the composition of installed thermal capacity in China. Among newly installed units of 600MW e and above, the portion of supercritical units is planned to increase. Within the area of the supercritical coal fired units, there are various competing technologies.
A commercial CFBC unit is being built by Lurgi in Liinen, West Germany at the Vereinigte Aluminumwerke (VAW). This unit will have a capacity of 84 MW(t) and will both produce high pressure steam (convective section) and reheat 2.8 x 106 Ib/hr molten salt heat carrier from 650° to 800°F (fluid bed heater section).
Supercritical and ultra-supercritical coal-fired combustion systems operate at higher temperatures and pressures and can achieve enhanced thermal efficiencies [in excess of 45% HHV] compared to conventional sub-critical pulverised coal combustion units. plants can also achieve significant reductions per KWh in CO2 emissions.

Ultra Supercritical Power Plants. In the quest for higher efficiency the trend is to go for still higher operating pressures. The next generation of power plants will operate with steam Pressures in the range of 300 bar. These are the Ultra Super Critical Power plants. Ultra Supercritical Units operate at temperatures of 615 to 630 deg C.

The typical basic design conditions for an A-USC system are indicated in Table 3.1 [8,9].As well as the system schematic drawing (Fig. 3.2), the double-reheat cycle is adopted to achieve the target thermal efficiency of 46% (HHV).The rated speed and the condenser pressure are assumed to be 3600 rpm and 5.07 kPa, respectively (722 mmHg, Vac., 1.5 inHg, A, respectively).
units and subcritical units and less efficiency than the Supercritical units. However in the last few years there were tremendous steps has been taken to scale up the CFBC Technology and design as the Supercritical units. Today 500 to 800 MW Supercritical CFBC units are available in order to compete with the PCC Fired one.

As a country with the largest amount of CFB boilers and the largest installed capacity in the world, China has 440 100–600 MWe CFB boilers with a total capacity of 82.29 GWe, including 227 units ...
Therefore, the appropriate design is CFBC. Although development of CFBC technology has been slow (presently, only 2% of the world's coal-based power plants use it), it is particularly suited for coal with lower heat content and high sulfur. The efficiency of its large-sized units (i.e., over 300 MW) can be similar to that of PCC units. 8.
