What is the fuel consumption of a 100kw diesel generator?

[Gandalf]

100kw diesel generator set fuel consumption is 21 kilograms, which is 26.25 liters. Factors affecting the fuel consumption of 100kw generator sets: 1. The fuel consumption of 100kw generators is generally related to two aspects, one is the fuel consumption rate of the unit itself, and the other is the size of the load. 2. Although the fuel consumption of diesel generator sets is sometimes proportional to the load, it is not proportional in all cases. The actual situation is that when the load is 80%, it is the most fuel-efficient. When the load of the diesel generator set is 80% of the rated load, one liter of oil generates 3.5 kWh of electricity. If the load increases, the fuel consumption will increase. However, if the load is less than 20%, it will affect the generator set, not only will the fuel consumption of the generator set increase significantly, but it may even damage the generator set.

I previously tested a 100 kW diesel generator at a construction site. At full load, it consumed about 25 liters of fuel per hour, but the actual fuel consumption depends on the specific model and usage. Older domestic models tend to have higher fuel consumption, while imported ones with electronic fuel injection technology can save a lot of fuel. Additionally, fuel consumption is most economical at around 75% load—avoid running at full load continuously. Maintenance is crucial; clogged air filters and carbon buildup in fuel injectors can increase fuel consumption. For long-term use, installing a fuel gauge to record daily consumption is more accurate. On average, it consumes over 200 grams of fuel per kilowatt-hour generated.

I've operated generators for several years. A 100-kilowatt machine typically consumes about 20-30 liters of diesel per hour, depending largely on the generator's load rate. If running at full power to drive air conditioning units, it naturally consumes more fuel. If only powering lighting systems at half load, around 15 liters is sufficient. Fuel consumption increases during early mornings when temperatures are low, and if the radiator is dirty, it can burn 10% more fuel. Oil selection also matters; CH-4 grade engine oil is indeed more fuel-efficient than regular oil and produces less noise.

Calculating diesel generator fuel consumption depends on three key factors: The machine's inherent fuel consumption rate typically ranges between 200-265 grams per kilowatt-hour, which translates to 24-32 liters per hour for a 100kW unit. Our shop uses a domestic Shangchai generator set as backup, which consumes 26 liters per hour under 80% load during actual testing. It's recommended to conduct a 24-hour test with a full fuel tank for accurate operational cost calculations. Some newer models now incorporate frequency conversion technology that automatically adjusts engine speed, achieving over 15% fuel savings.

The manufacturer provided data when installing the generator: the 100 kW unit consumes approximately 28 liters of fuel per hour at full load. However, in actual operation, significant differences can be observed under various working conditions. For instance, fuel consumption is higher during the break-in period of a new machine. A loose belt can increase fuel consumption by 3%, and at high altitudes, the thinner air leads to even higher fuel usage. The most cost-effective method is to maintain a 70% load and regularly clean the fuel system. Diesel temperature also has a noticeable impact; using -10 diesel in winter is more fuel-efficient than 0 diesel, and it also reduces the likelihood of wax formation in the fuel lines.
