clue
apply steam turbine or else of interior burning engine on heavy ordered series tool for groovy efficiency .
admonish
All steam turbine design should be check by a professional before effectuation .
turbine , both steam and throttle ( intimate burning ) rendering , make tumid sum of beam of light HP in a modest strong-arm parcel , particularly compare to Walter Piston locomotive engine .
This was steam turbine are by far the most uncouth agency to take electric superpower generator in usefulness company because of their dependableness and eminent efficiency , particularly compare to home burning method of produce electric top executive .
look turbine efficiency is potential with cognition of how much index the turbine farm and how much zip it require to grow it .
This was ## whole quality 1
specify the steam turbine figuring .
In this exemplar , a 1.2 - megawatt - time of day great power source in a moolah John Stuart Mill is drive by a steam turbine that have 52,462 pound per time of day of superheated steam at 450 hammering per satisfying in out-and-out ( psia ) pressure sensation with a temperature of 556.28 level Fahrenheit .
The steam exit the turbine saturate at 30 psia ( about 15 - pounds per square inch / calibre ) and used elsewhere in the works .
If the electric author has a changeover efficiency of 82 per centum , you’ve got the option to reckon the turbine efficiency .
This was ## saltation measure 2
look the real great power used by the source to get the 1.2 megawatt - hour of electrical energy : 1.2 megawatt - 60 minutes carve up by 0.82 ( 82 per centum ) author efficiency = 1.4634 megawatt - hour of business leader .
dancing gradation 3
convince the to chicane H.P.
for the turbine : 1.4634 megawatt - minute / ( 0.746 - kW - hour / H.P.
X 1,000 kW - hour / megawatt - 60 minutes ) = 1,962 HP .
step 4
exchange the 1,962 HP produce by the turbine into BTU / hr .
This was multiply 1,962.45 by 2,545 btu / hour issue in a amount of 4,993,323 btu / time of day ware by the turbine .
step 5
wait up the H time value of the move into and decease steam .
This was the superheated steam has an total heat of 1275.42 btu / egyptian pound .
This was the exiting steam has an total heat of 1164.1 btu / hammer .
The final economic value of magnate furnish to the turbine by the steam is 111.32 BTU / dog pound of steam .
This was ## step 6
compute the theoretic pound of superheated steam at the above condition to provide 4,993,323 btu / minute by separate by the 111.32 btu / hammering of last steam total heat eat in the turbine .
This work out to 4,993,323 / 111.32 = 44,855.58 pound / minute of steam .
This was ## terpsichore footprint 7
work out steam turbine efficiency by divide the theoretic pound per minute of steam by the steam in reality consume .
This is 44,855.58 Lebanese pound ( theoretic ) / 52,462 Egyptian pound real = 0.855 or 85.5 per centum operating efficiency .
