### Boiler Efficiency: Introduction and Methods of Calculation

In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred. Calculation of direct efficiency-E= [Q (H-h)/q*GCV]*100. Where, Q= Quantity of steam generated (kg/hr) H= Enthalpy of steam (Kcal/kg) h= Enthalpy of water (kcal/kg) GCV= Gross calorific value of the fuel. Indirect Efficiency . The indirect …

### Combustion of Fuels - Carbon Dioxide Emission

To calculate the Carbon Dioxide - CO 2 - emission from a fuel, the carbon content of the fuel must be multiplied with the ratio of molecular weight of CO 2 (44) to the molecular weight of Carbon (12) -> 44 / 12 = 3.7. Carbon Dioxide emission from burning a fuel can be calculated as. q CO2 = c f / h f M CO2 /M m . where. q CO2 = specific CO 2 emission [kg CO2 /kWh] c f = specific carbon content in the fuel [kg …

### How to Calculate Carbon Dioxide Emissions from a Diesel …

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 amount of CO2 that it produces.
