Single layer flow insulation using a wire mesh for high temperature combustion furnaces is proposed. The gas temperature drop and heat transfer characteristics across a wire mesh were measured experimentally. Temperature drop increases with increasing inlet gas temperature, on the other hand, decreases with increasing modified Reynolds number and the porosity of wire mesh. In order to characterize heat transfer characteristics, relationships of modified Nusselt number Nu' and modified Reynolds number Re' were obtained. These relations are indicated as Nu'=a+b×Re'^c, and each coefficients a,b,c changes mainly by the porosity of wire mesh.
