Air Fuel Ratio Effect on Combustion Efficiency

The air-to-fuel ratio defines the amount of air needed to burn a specific fuel. The air-to-fuel ratio defines the amount of air needed to burn a specific fuel. The conventional fuels used in the combustion process are oil (#2, 4, and 6), diesel oil, gasoline, natural gas, propane, and wood—ratios for common gases, liquid, and solid fuels noted in Table 1.1 and 1.2.

Steam gasification of various feedstocks at a dual

Gasification of biomass is an attractive technology for combined heat and power production as well as for synthesis processes such as production of liquid and gaseous biofuels. Dual fluidised bed (DFB) technology offers the advantage of a nearly nitrogen-free product gas mainly consisting of H2, CO, CO2 and CH4. The DFB steam gasification process has been developed at Vienna University of
