Research on Temperature Field and Heat Transfer inside Catalytic Combustion Furnace of Natural Gas

Abstract:

This article discussed the temperature field and heat transfer inside catalytic combustion furnace with Pd-based honeycomb monoliths of lean natural gas-air mixtures. The monoliths need to be ignited by gas phase combustion with the excessive air coefficient at 1.63 during the period of start-up process. After local catalytic ignition, a steady state has reached. The temperature field was measured by thermocouple K of diameter 1.0. It was shown that the temperature gradient changed according to the different position inside catalytic combustion furnace. When the furnace was used for heating equipment, heat transfer included mainly heat radiation and convection. For high radiation heat, local surface temperature of monoliths plays a decisive role.
