Experimental study on a high efficient and ultra-lean burn meso-scale thermoelectric system based on porous media combustion

, 2021
Current combustion-based meso-scale thermoelectric systems generally operate at stoichiometric ratio, which leads to high emissions. Lean burn is beneficial to the burning of low-concentration gas and emissions reduction. To exploit the thermal energy of

Reducing Methane Emissions From Lean Burn Natural Gas Engines with Prechamber Ignited Mixing-Controlled Combustion

Journal of Engineering For Gas Turbines and Power
The oil and gas industry heavily relies on lean burn spark ignited natural gas reciprocating engines. These engines produce pollutants, such as NOx and CO, but due to their premixed nature, also produce relatively large amounts of unburned methane (CH4)
