文摘
- •
Combustion in heat recuperation micro-combustors with different materials was studied.
- •
Heat concentration is more obvious with thermal conductivity decreasing.
- •
Combustor with copper baffles has uniform temperature distribution and best preheating effectiveness.
- •
Influence of wall thermal conductivity is negligible on OH(s) coverage.
- •
Methane conversion rate firstly increases and then decreases with h increasing.
