What is the purpose of GSC?
Function. The GSC gene defines neural-crest cell-fate specification and contributes to dorsal – ventral patterning. Over activation in Xenopus promotes dorso-anterior migration and dorsalization of mesodermal tissue of the cells along with BMP-4.
What is GSC in thermal power plant?
GSC (Gland steam condenser) is simply an efficiency improver in thermal power plants. The working of GSC is quite simple as like condenser. It has shell inside which some tubes are mounted.
Why reheaters are used in thermal power plant?
A reheater is basically a superheater that superheats steam exiting the high-pressure stage of a turbine. By reheating steam between high-pressure and low-pressure turbine it is possible to increase the electrical efficiency of the power plant cycle beyond 40\%.
What is slip ratio in thermal power plant?
Posted On: Nov 18, 2020. In two-phase fluid flow, a slip ratio is used. It is defined as the velocity of the vapour phase divided by the velocity of the liquid phase. Slit ratio is unity when the bubble in the fluid just forms. Slit ratio increases as a bubble in the fluid starts to collapse and form a larger bubble.
How do I increase my condenser vacuum?
10 Tips to Ensure Reliable Vacuum Condenser Performance
- TIP 1: Conservatively Estimate Noncondensible Loading.
- TIP 2: Understand Vapor-Liquid Equilibrium of the Vapor Components in Your Process.
- TIP 3: Properly Elevate a Vapor Condenser.
- TIP 4: Define the Range of Cooling Water Temperature and Flow Rate.
What is the effect of high vacuum in turbine?
Effect of over vacuum? It causes sub-cooling effect where hot well temperature reduces more than design which required to be added in boiler leads to heat loss.
What are reheaters?
Definition of reheater : one that reheats: such as. a : a furnaceman who reheats metal. b : a receiver furnished with means for heating the steam in a compound engine or turbine. c : an apparatus for reheating compressed air before use to prevent excessively low temperatures due to expansion.
What is reheat and non reheat turbine?
description. In turbine: Reheat and nonreheat turbines. If high-pressure, high-temperature steam is partially expanded through a turbine, the efficiency can be increased by returning the steam to the steam generator and reheating it to approximately its original temperature before feeding it back to the turbine.
How do you calculate slip factor?
Slip factor is defined as the ratio of real tangential velocity out of the rotor to its ideal value (Figure 4.6). It is calculated both theoretically and experimentally where the latter is obtained either directly from velocity profile or indirectly from flow rate and torque measurements.
What is slip ratio in two-phase flow?
Slip ratio (or velocity ratio) in gas–liquid (two-phase) flow, is defined as the ratio of the velocity of the gas phase to the velocity of the liquid phase. In the homogeneous model of two-phase flow, the slip ratio is by definition assumed to be unity (no slip).
