How much fuel does a 5000w diesel heater consume per hour?

[SanBenjamin]

Based on the specific fuel consumption estimation of diesel engines, approximately 0.3 liters of fuel is consumed per kilowatt-hour. For a 15KW unit, the hourly fuel consumption would be 15*0.3 liters = 4.5 liters. Here are the detailed explanations: 1. Diesel generator sets: Diesel generator sets refer to power machinery that uses diesel or similar fuels, with a diesel engine as the prime mover to drive the generator for electricity production. 2. Performance: The diesel engine converts the thermal energy released from diesel combustion into kinetic energy, and the generator then converts this kinetic energy into electrical energy. During each conversion process, a portion of the energy is inevitably lost. The converted energy is always only a fraction of the total energy released by combustion, and this percentage is referred to as the thermal efficiency of the diesel engine. To practically describe thermal efficiency, diesel generator manufacturers commonly use the G/KW.H parameter, which indicates how many grams of fuel are consumed per kilowatt-hour. By converting this unit into liters, one can immediately determine the amount of fuel consumed in liters.
