Open Cycle Gas Turbine - an overview | ScienceDirect Topics

Radiation and oil-cooler losses only amount to 1–2%. The waste gas is clean – nearly all air at over 500°C on full load. If the waste gases were passed through a waste-heat boiler to generate steam, the 1.25 MW set could generate some 4500 kg/h at 1.75 MPa gauge, raising the combined electrical and steam-generation efficiency to around 50%.

Leaky boiler heat exchangers leak water and are easy to spot. Furnace heat exchangers mix combustion gases with house air when they leak—an important safety reason to have them inspected. Adjust the controls on the boiler or furnace to provide optimum water and air temperature settings for both efficiency and comfort.

Flue gas composition is significantly affected by the combustion conditions. Concentration of gaseous species upon firing 1.7% S coal (chemical composition is given in Table 1) was calculated at 1300 °C, assuming thermal equilibrium, and presented in Figure 2 as a function of air–fuel ratio. In this chapter, air–fuel ratio is defined by the ratio of their weights; air–fuel ratio of 10

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 [1]. where. q CO2 = specific CO 2 emission [kg CO2 /kWh]
