Could you explain why connect gland steam area of HP turbine with reheat inlet line of IP TURBINE?

BECAUSE IF YOU DIDN'T TEMPERATURE AND PRESSURE DROPS WOULD ALREADY BE TOO BIG TO ALLOW 2 EXTRA STAGES OF TURBINES (IP AND LP'S). EVIDENTLY TO RE-CIRCULATE STEAM BACK TO BOILER AND ON TO IP TURBINE IS MORE COST-EFFECTIVE (I.E.: MAKES YOU GAIN MORE MONEY) THEN PERHAPS NOT BEING ABLE TO ADD ANOTHER 2 STAGES BUT ONLY ONE (I.E.: IP). THIS WAY YOU CAN MAKE SURE TO EXPLOIT ALL ENERGY OF THE STEAM FLOW. IF YOU DIDN'T REHEAT LOSSES WOULD BE GREATER THAN GAINS pleas be more clear in your answer and tll mw th benifet of the hp & lp glands

What is reheat factor in power plant?
The reheat factor in the steam turbine refers to the Thermodynamic effect on the turbine efficiency. Others factors includes the cumulative heat, and the steam turbine condition curve.
Steam turbine heat rate formula?
The efficiency of a steam turbine is just the ratio of power out to power in, but if you want to be able to calculate it from the basic mechanical design, this is a specialised topic. In the link below is a general description of steam turbines, in the references and additional reading list there are some references that may help you.
How do calculate heat rate turbine gas?
Turbine cycle heat rate is a measure of the turbine efficiency. It is determined from the total energy input supplied to the turbine divided by the electrical energy output. The energy input is the difference between the energy in the steam supplied to, and leaving from the turbine. The total energy supplied is the sum of the steam mass flow rates to the turbine multiplied by their respective enthalpies. The energy leaving is the sum of mass flow rates exiting the turbine multiplied by their respective enthalpies. Take the difference in the total energy supplied and leaving, divide by the electrical output and this gives you heat rate, typically expressed in Btu/kWh or kJ/kWh. This is easy for a single source of steam passing through the turbine to a condenser, but gets a bit more tricky for reheat turbines with multiple extractions as all the streams in and out have to be accounted for.
What is the purpose for nozzle?
as a geometrical analysis of the diffuser, the cross sectional area will be increased and converts the pressure into velocity, so the steam pressure will be drops and its velocity will be increased.
What is a jet engine afterburner?
a jet engine afterburner is when you put a lot of gas to the engine and you go very fast... An afterburner (or reheat) is an additional component added to some jet engines, primarily those on military supersonic aircraft. Its purpose is to provide a temporary increase in thrust, both for supersonic flight and for takeoff (as the high wing loading typical of supersonic aircraft designs means that take-off speed is very high). On military aircraft the extra thrust is also useful for combat situations. This is achieved by injecting additional fuel into the jet pipe downstream of (i.e. after) the turbine. The advantage of afterburning is significantly increased thrust; the disadvantage is its very high fuel consumption and inefficiency, though this is often regarded as acceptable for the short periods during which it is usually used.

What is a boiler reheater?
In a reheat turbine the stean first enters high speed turbine so its temp and pressure reduces before entering low speed turbine so a reheater is used to reheat the cooled steam
What is reheat factor?
It is the ratio of cumulative heat drop to isentropic heat drop in a multistage steam turbine.
What is the advantage of rankine reheat cycle?
Among other advantages, this pervents the vapor from condensing during its expansion which can seriusly damage he turbine blades, and improves he efficiency of the cycle, as more of the heat flow into the cycle occurs at higher temperature.

Formula for calculating the heat balance for steam turbine hall?
The guaranteed heat rate, indicated on performance data table of power plant is calculated in accordance with the following formula: HR = (Qms x Hms - Qfw x Hfw + Qhrh x Hhrh - Qcrh x Hcrh - Qas x Has + Qmu x Hmu) x 3600 / W HR = heat rate [kJ/kWh] W = gross power output [kW] Q = mass flow [kg/s] H = enthalpy [kJ/kg] Subscript: ms = main steam fw = boiler feedwater hrh = hot reheat steam crh = cold reheat steam as = auxiliary steam extraction from turbine cycle for boiler users mu = make up water at condenser
What is the purpose for nozzle?
as a geometrical analysis of the diffuser, the cross sectional area will be increased and converts the pressure into velocity, so the steam pressure will be drops and its velocity will be increased.
How do you reheat fully cooked smoked chicken?
You can reheat fully cooked smoked chicken in the oven on a low temperature. You can also reheat this type of chicken in the microwave.
What is the best way to reheat sushi?
you don't reheat a sushi.. Sushis are eaten cold...
Does it have a "reheat" option for heating up leftovers?
Yes this microwave does include a "reheat" option for reheating leftovers.
What rhymes with preheat?
