Webb1 aug. 2024 · A rich fuel mixture is another kind of air-fuel mix that has more fuel quantity than the ideal fuel quantity needed for the whole combustion process. The combustion … All diesel engines can be considered to be lean-burning with respect to the total volume, however the fuel and air is not well mixed before the combustion. Most of the combustion occurs in rich zones around small droplets of fuel. Locally rich combustion is a source of particulate matter (PM) emissions. WebbThe hydrogen-lean syngas flames with H2O dilution have the lowest NO production rate among them, due to a reduced reaction rate of NNH + O → NH + NO. But for hydrogen-rich syngas flames with CO2 dilution, the flame temperatures decrease significantly, which leads to a reduction of NO formation from Zeldovich route. birthplace of joseph r biden
