Q:I know a train runs on an electric engine powered by a diesel generator. Would something like this be feasible for cars?
It really isn't the best way to go. Anytime you convert energy, some efficiency is lost. It is more efficient to propel the car directly with the engine, rather than propelling the car with an electric motor that is powered by a generator powered by the engine. Despite this loss of efficiency, this setup is appealing for use in trains because of their heavy loads. To drive a train directly with a diesel engine requires a massive transmission. Designers ran into problems with the transmission gears breaking due to the massive forces associated with moving a train. Instead, they propel the train with electric motors, which require no transmission. But the motors require power, so they use diesel powered generators. So there you have it. The diesel/electric setup is not appealing for cars, because stresses are low enough that a normal transmission can be used, and there is more efficiency by driving the car directly by the piston engine. The diesel/electric setup is appealing for trains because it eliminates the need for a transmission, which is bulky and prone to breaking.
Q:Having lots of diesel fuel to make electricity (200-800KW)is it better to use a diesel generator or a steam turbine?(Remember : the only way to produce steam is burning diesel)Does anybody know how many KWh can make per 1000gal?
Neither. At these sizes, it's most efficient to use a gas turbine, in which the expanding gas of the burning fuel turns the turbine directly, rather than going through the lossy process of boiling water. A large gas turbine can be as much as 57% efficient in electricity production, which is far higher than a diesel engine. A gallon of diesel fuel contains about 130,000 BTU, or 137 megajoules (MJ). At a 55% conversion rate, that would mean 75.35 MJ of electricity. There are 3.6 MJ in a KWh, so that's 20.9 KWh per gallon of diesel, or 20,930 KWh for 1000 gallons.
Q:I am writing about the affect on the economy, environment, and the health aspect.
Does the disposable bottle plastic contain BPA (Bisphenol A)? Medical researchers have raised ominous concerns over this chemical in recent years. Canada and the EU have outlawed this material for use in baby bottles only as recently as 2010. Canada has gone even further by declaring BPA toxic to humans. The US has yet to regulate this chemical in any meaningful way. Your typical disposable water bottle maker doesn't disclose the materials the bottle is made out of on the product label. They don't have to because there's no law that compels them to. BPA has been used in polycarbonate and thermoplastics since the late 1950s. In older buildings an epoxy form of it has been used to coat the inside of water pipes. It is also used to coat the inside of canned foods in your supermarket. Free-form BPA can be found on carbonless copy paper, on store receipts, movie tickets, to name a few. A government study in 2008 estimated detectable levels of BPA in urine samples in over 90% of the U.S. population. BPA mimics the human estrogen hormone inside the human body. Recent studies include concerns over a long list of specific health ailments. The list of health concerns include: Obesity Heart Disease Neurological Disorders Hyperactivity Attention Deficit Disorder Propensity for Drug Abuse Thyroid Disorders Breast, Brain, and Prostate Cancers Reproductive Disorders See source links below for more reference material and news articles.
Q:how is the diesel power transmitted to the traction wheels in a diesel locomotive
Diesel hydraulic transmission was used a great deal in Germany in the 50s and 60s and may still do (see link to Voith) Also the Italians are using them - Trenitalia took delivery of 25 in 2000. British Railways (Western Region), which still thought of itself as the Great Western Railway in the late 50s and early 60s ordered main line diesel-hydraulic locos from Germany, or using German transmission (Westerns, Warships, and Class 35) when other regions were ordering diesel-electric locos. The Railway Gazette reports that the diesel-electric v diesel-hydraulic 'battle' is to recommence. Hydraulic transmission is akin to, but very different in detail to, an automatic transmission on a car. The last link tells you all you need to know.
Q:Hi. We're off grid and therefore installing a 3 phase Diesel generator. Each phase is rated at 20 Amps continuous(23 Amps max). we want to run 3 Split type ACs, one on each phase, plus some other small appliances.Our problem is that each AC has a start up current of 20 Amps, which will trip the safety circuit on the generator everytime it comes on.The ACs running current is only 8 Amps, but jumps to 20 Amps for a split second everytime the Compressor comes on.Is there a simple way to control the start up current on the ACs? I read something about putting a coil of wire on the input of the Compressor. I tried that with a water pump just to check if it works. The surge current was still there.Any ideas if I can use a Capacitor? If yes, can you tell me what capacity I should use? If you give me the formula I can figure it myself. We run on 220-240 Volts, 50 HZ.Thanks for your answers.
Is it too late to switch to a 240 volt single phase generator of the same capacity? This would have a 60 amp capability and would handle the surges with no trouble. I don't see how a capacitor will help. If you are stuck with the 3 phase generator, perhaps you can switch the ACs for ones with 3 phase motors. That will spread the surge over the 3 phases. There are also soft-start ACs .
Q:i would like to get the machine that is at least 2000 0r 3000 kw
waw. That's a lot of energy for just a house. You got to be kidding me. okay, you can find diesel generator if you like, but you need to keep storage of diesel enough for it.
Q:I want to build a diesel engine driven generator. The type of gen I have is asynchron, 400/690 V, 7,5 kW, 9,4 kVA and I was told that I need to stimulate it with capacitors (the unit is supposed to work without connection to a public netstand-aloneisland-service). Who can give me instructions how to do the el. part, size/type of capacitors etc?
Because it lacks a separate field circuit, an induction generator cannot produce reactive power. In fact, it consumes reactive power, and an external source of reactive power must be connected to it at all times [1]. So you are right that you will need a three-phase capacitor bank at the output terminals (delta-connected). How to size the capacitors? That depends on a few things. Namely what kind of loads are going to be attached to it. I presume this is going to be an emergency generator operating alone (most induction generators are used this way nowadays). In that case, your capacitor bank will need to account for the generator consuming reactive power and the loads consuming reactive power. So, if you know what you are going to connect to the generator, figure up an estimate of the total reactive power of your loads. Then estimate how much reactive power your generator consumes (not sure how to do this; maybe estimate from your 7.5kW and 9.4kVA ratings?). Finally, to size your capacitors equate the total power consumed by gen and loads to this formula: estimated_3phase_power_consumed 3*(line-to-line_volt)^2/X where X 1/(2*pi*freq*C) Solve for C and there you go. My source indicates that the output voltage for an induction generator can vary quite a bit with varying inductive load, so bear that in mind and maybe oversize the caps a bit. Also, the types of capacitors should be able to withstand AC obviously and be rated within your expected operating temp, etc, etc. Good luck.
Q:I want to know if i can get a 40kvh generator (witch is usually ran by 4 cylinder diesel engine) to run with a water wheel and some poulies??
If you mean 40kva, then you are talking 30 horsepower. That's bigger than most of the huge waterwheels that used to power the industrial revolution era cotton mills. If you happen to live at the bottom of a huge waterfall you might have a chance, but the engineering would be something else,
Q:how much power do they require and how much room do they take up?
If you are talking about the truck (traction) motors on a locomotive, then whole power system! diesel engine, generator, exciter generator, truck motors, can range anywhere from seven hundred horsepower for a switch engine up to several thousand horsepower for a line haul locomotive. The traction motors get their power from the generator which is connected to the diesel engine. There is no direct mechanical connection from the diesel engine to the wheels. All the diesel engine does is turn the generator. The power from the generator is what running the traction motors which in turn drives the wheels of the locomotive. That is where the term diesel over electric comes from. In short the diesel engine drives the generator. The power from the generator drives the traction motors. The traction motors drive the wheels. The wheels drive the locomotive. The amount of power the generator puts out is controlled by two things. How fast it is turning (number of RPM and how much excitation voltage it's fields are being excited with by the exciter generator. Both the RPM's and the excitation voltage is controlled by the engineer. The advantage of using diesel over electric is they can tandem several locomotives together to pull long trains and be able to control them all from the lead engine. (Locomotive) As far as size Look at the trucks on the locomotive. The area between the wheels is pretty muchly taken up by the traction motors. Here is another fact. The generator is a DC generator and the traction motors are DC motors. Most of the time they are series wound DC motors for better starting torque since they are always coupled to a load. Here is another fact from the been there done that file! Traction motors are nasty and dirty to work on like when you have to change brushes and seat the new brushes and horne the commutator
Q:I planned that the factory be fully mechanised. Public power supply is very poor. I wanted to purchase diesel generators but i have been advised by a friend that solar generators are more cost effective. Is solar a good source of energy to power such a factory?
Yes, it can be fully solar. Very power comsuming factories are autonomous. If you dont find how to, if you want e-mail me and i will put you in touch with some companies. For your info, some companies not only are autonomous, they resell power while they dont use it.
