Combined cycle power plant - Wikiped

2019-11-15 · The thermodynamic cycle of the basic combined cycle consists of two power plant cycles. One is the Joule or Brayton cycle which is a gas turbine cycle and the other is Rankine cycle which is a steam turbine cycle. The cycle 1-2-3-4-1 which is the gas turbine power plant cycle is the topping cycle. It depicts the heat and work transfer process taking place in high temperature region.

Low-alloyed steel grades for boilers in ultr

Many heat-resistant ferritic steels for power boilers have been developed during the last century. Fig. 2.1 shows the development progress of ferritic steels categorized into 2Cr, 9Cr, and 12Cr series. Of them, 2.25Cr-1Mo steel (T22) is the typical conventional low-alloyed steel developed in 1930s that has been used in the conventional and ultra-supercritical power boilers even at present.

Research Challenges of Heat Transfer to Supercritica

In conventional fluids, Reynolds analogy is widely applied and constant turbulent Prandtl number is assumed. This assumption might be valid in case the molecular Prandtl number is close to 1. However, at supercritical conditions, the molecular Prandtl number varies in a large range, as shown in Fig. 3. Obviously, the validity of the Reynolds

Materials for ultra-supercritical coal-fired power plan

The ultra supercritical boiler was found to have approximately 7% more suspended weight than a conventional supercritical boiler with the same plant output. This is interesting to note because the USC boiler is actually smaller than conventional supercritical unit. The USC unit is nearly 20% narrower than the conventional supercritical unit.
