Effects of Hydrogen-Rich Gas Injection on Combustion Characteristics in Blast Furnace Raceway and Thermal Load of Tuyere: A Numerical Simulation Study

Metals
Hydrogen-rich gas (HRG) injection is a promising low-carbon solution for blast furnace ironmaking. This study conducted numerical simulations in the lower part of a blast furnace to analyze the combustion behavior of coinjected coke oven gas (COG) and ...

Mechanism of methanol and formaldehyde emissions from methanol-fueled engines

Fuel Processing Technology
Methanol, as a low-carbon fuel, has broad application prospects in engines. The mechanism of methanol and formaldehyde was investigated respectively in a methanol premixed combustion test bench (PCTB) and a 304 stainless-steel flow reactor (SFR).

Numerical investigation on combustion performances of premixed H2-air jet flames above a sudden expansion micro-nozzle

Case Studies in Thermal Engineering
Our previous study demonstrated that divergent micro-nozzles designed for H2-fueled domestic gas stoves can achieve a higher flame temperature than conventional straight micro-nozzles, but are more susceptible to flashback. To address this safety concern,
