generator installation Frequently Asked Questions
first law of thermodynamics?
A 4250-hp aircraft engine is used in a power station in England to run a 3.0-MW generator to supply electricity during peak-load periods. The engine consumes 370 g of kerosene per kilowatt-hour of energy produced. What is the overall efficiency of the installation?
Burning a fuel sets off an amount of heat equal to the net calorific value (also known as lower heating value).
Net calorific value of kerosene is about:
CV = 43.1MJ/kg
So heat liberated by burning 370g kerosene is
Q = 0.370g ∙ 43.1MJ/kg = 15.947MJ
Efficiency of the aircraft engine is the ratio of energy produced to that amount of heat, i.e.
η_engine = 1 kW hr / 15.947MJ
= 3.6MJ / 15.947MJ
= 0.2257
Efficiency of the power generator equals ratio of power output to power input from aircraft engine:
η_generator = 3.0MW / 4250hp
= 3.0MW / 4250∙745.7 W
= 0.9466
Overall efficiency of the system equals product of the efficiency of engine and generator:
η_generator = η_engine ∙ η_generator
= 0.2257 ∙ 0.9466
= 0.2137
= 21.37%
I am thinking about getting an automatic backup power generator.?
I presently have oil heat in my home and have been told that fuel oil can be used to power the generator instead having to get bottled gas installed. Is this true?
I figure if I am going to do this, I'd like to power the entire household: furnace, sump pump, well pump, refrigerator, stove and lights. What is the price range for such a set up? Typically, is there a percentage paid up front and if so, how much? Can one contractor install the entire system: pad, generator, switch board, etc.? Am I better off buying the hardware and then just hire a contractor to perform the installation? If the contractor supplies the hardware, what is the typical mark-up, if any?
What is the best way to determine that the contractor is reputable and knows what they're doing?
After being without power during two recent hurricanes I decided to scrap my regular generator and go with a whole house set up. This is operated on propane, will kick on when the power goes off and is capable of heating/cooling the entire house. Just be sure you get one large enough to operate the things you may need.
One contractor did the entire job for me and I have been extremely pleased with the work as well as the price. Total cost ran around $5500. but if you go through a period of 2 weeks without power you will know its worth the money.
