There are a variety of used diesel generators available on the market. In order to secure the best and most cost-effective purchase, it is a good idea to search the online sites that are available offering used diesel generator for hire which can be bought at cheaper or discounted price. When buying a diesel powered generator, it is important to consider the purpose for which the generator will be used. This is important in calculating the required wattage to be used. This helps in narrowing down on the right kind of new or used diesel powered generator when buying, such as a small diesel generator or a portable diesel generator. 500kw diesel generator
A small diesel generator, used in the home, will use far less wattage than – for example – a large industrial generator utilised on a large vehicle like a ship. Diesel powered generators are used on ships as a source of power for propulsion. Electric drives like diesel generators for ships were developed prior to WW I and these generators were specified in many warships built during WW II because manufacturing capacity for large reduction gears was in short supply, compared to capacity for manufacture of electrical equipment. Such a diesel-electric arrangement is also used in some very large land vehicles.
The largest cost when it comes to diesel plant owning generators is that of fuel consumption and operating cost for power applications. However, for back up new and used generators the largest cost and therefore primary financial concern is the capital cost. Specific consumption varies, but a modern diesel plant will consume between 0.28 and 0.4 litres of fuel per kilowatt hour at the generator terminals. However, although diesel engines are called diesel engines, it doesn’t mean that they can only work with diesel fuel. The engines can work with the full spectrum of crude oil distillates, from natural gas, alcohols, gasoline, wood gas to the fuel oils from diesel oil to residual fuels. This is implemented by introducing gas with the intake air and using a small amount of diesel fuel for ignition. Conversion to 100% diesel fuel operation can be achieved instantaneously.
New and used diesel generators are used as back up power supplies during power failures. Also, a diesel generator set (which is a combination of a diesel engine, a generator and various ancillary devices) routinely support main power grids worldwide in two distinct ways: Peak Saving and Grid support. Peak savings see diesel powered generators being turned on at peak times of maximum demand for electricity, which is generally mid-afternoon in winter in colder climates and midday in summer in warmer climates. Grid support sees emergency standby diesel generators such as those used in hospitals, water plant etc., used as a secondary function. These generators are widely used in the US and the UK to support the respective national grids at different times for a variety of different reasons.
