The traditional subcritical
technology, which achieves 33 percent to 38 percent efficiency, is obsolete, and, instead, the supercritical technology was deployed in recent past.
BHEL is the market leader in both the subcritical
as well as the supercritical segments in the country.
GNPower-Mariveles is a 604-MW subcritical
thermal-power plant which started operations in 2014, while GNPower-Dinginin is a new project consisting of 2x668-MW supercritical thermal power plant.
GNPower Mariveles owns the 604-MW subcritical
coal-fired power plant which started operations in 2014.
We have shown that subcritical
water is a good candidate for the depolymerization reaction medium, and the recovery yields of plastic monomers were significantly decreased at higher temperatures (in supercritical water) .
The studies of Kaya  on semi-elliptical side weirs in subcritical
flow showed that the discharge coefficient of these weirs is more than classic weirs.
This add-on is a subcritical
water extractor that uses water to release the amino acids from a soil sample, because liquid-based analysis is several orders of magnitude more sensitive than gas-based methods, according to a statement on NASA's website.
The collection compiles research findings on the mechanisms and conditions leading to environmentally induced subcritical
crack growth under the influence of static or dynamic tensile stress.
GMCP is a 604-MW subcritical
thermal power plant, which started operations in 2014, while GNPD is a new project consisting of 2 x 668-MW supercritical thermal power plant, located in Bataan.
The ultra-supercritical boilers have a very efficiency and very low emissions compared to subcritical
and supercritical technology boiler.
These plants operate at thermal efficiencies of up to 45 percent (LHV) which is a 7-10 percentage point improvement over older subcritical
plants which generally operate below 185 bar.
SBPL has explained that compared to the subcritical
power plants, those running on supercritical technology "operate at higher pressures leading to higher efficiencies and significant reductions in emissions over the expected life of the plant.
