How to Calculate Carbon Dioxide Emissions from a Diesel Generator- diesel generator thermal efficiency ,2,778 g x 3.66 x 0.99 = 10,084 g. Each gallon of diesel fuel produces, on average, 10,084 g of CO2, or about 22.2 lb. So if your diesel generator uses, for example, 15 gallons of diesel fuel per hour, it'll be producing: 15 gallons/hour x 22.2 lb./gallon = 333 lb. Just insert the fuel burn rate for your diesel generator, and you'll get the ...Heat Rate of a Generator and Its Impact on Efficiency2021104·Heat Rate Degeneration.
