What to do about turbine rotor differential expansion?
my LP turbine differential expansion increase ,when rated gland steam temperature maintain.
Why LP turbine diaphragm breaks?
Lp turbine diaphragm breaks due to positive pressure inside the condenser because of steam expansion.
Cause of increase in LP Turbine differential expansion?
1. Low vacuum at high loads 2. High HRH temp 3.High steam flow 4. high gland steam temperature
What is the use of hp and lp dosing in boilers?
hp dosing used for precipitate the silica from bfw in drum and lp dosing used for increase the ph in boiler to maintain 9.5 to 10.5
What is casing expansion of steam turbine?
casing and shaft are made of alloy steel they are supposed to expand when heated (at/2 *length of turbine.).wherea is coefficient expansion of material.t=finaltemperature ( of casing or shat)-ambienttemperaturel=length of turbine in meter
What to do about turbine rotor differential expansion?
my LP turbine differential expansion increase ,when rated gland steam temperature maintain.
Why LP turbine diaphragm breaks?
Lp turbine diaphragm breaks due to positive pressure inside the condenser because of steam expansion.
What is lp and hp heaters?
In regenerative cycle LP/HP heaters are used to raise condensate/feed water temperature by extracting/bleed steam from LP and Hp stages of steam turbine in order to improve the efficiency of the plant
What is absolute expansion of steam turbine?
it's the thermal expansion in the casing of hp or ip turbine can be noticed by journal or thrust bearing when moving <<
Difference between HP and LP separators?
HP used for high pressure well and LP for low pressure well in oil and gas industries.
Cause of increase in LP Turbine differential expansion?
1. Low vacuum at high loads 2. High HRH temp 3.High steam flow 4. high gland steam temperature
Why vacuum breaker is provided in condensing turbine exhaust?
it is mainly provided to save the difram of lp turbine, it is initially use to seal d vacuum's.
What is the use of hp and lp dosing in boilers?
hp dosing used for precipitate the silica from bfw in drum and lp dosing used for increase the ph in boiler to maintain 9.5 to 10.5
What is casing expansion of steam turbine?
casing and shaft are made of alloy steel they are supposed to expand when heated (at/2 *length of turbine.).wherea is coefficient expansion of material.t=finaltemperature ( of casing or shat)-ambienttemperaturel=length of turbine in meter
What is expansion turbine?
differential expansion is refer to differential distance between rotor blade and fix blade.rotor expand toward generator and casing expand toward control valve.when temperature increase ,expansion in casing and rotor.so rotor mass is less than casing which rotor expand more than casing.
How much power did the Titanic's centre turbine produce?
it did not have horsepower, but it could sail up to 25 knots and was at 22 when it struck the iceberg answer 2 59,000 hp was produced at maximum revolutions by Titanic. Titanic had two reciprocating steam engines which made 30 000 HP together. She also had one steam turbine with an output of 16 000 HP. This is a total of 46,000 HP for propulsion.Adding the electrical generators and other support machinery, Titanic total output is listed as 51 000 HP.
What is the difference between an HP supercell and an LP supercell?
in an hp supercell high amounts of hail and rain obscure everything and often hide tornadoes that are inside of them. they make tornadoes nearly impossible to see. an lp supercell has very little percipation and due to that doesn't have a tornado as often as an hp. however an lp supercell has great visibility.
