Weakening of gas convection heat transfer by ceramic fiber aluminum foil blanket
The porosity of the ceramic fiber blanket is very high. The gas is divided into almost stationary small air hole, and the pressure in the dispersed multi hole bin is certain. The pressure will form a dense solid shielding (forming shielding pressure) with the solid fiber, which hinders the intrusion of hot gas flow and weakens the heat loss; at the same time, the density of aluminum foil directly hinders the gas. Convection. Therefore, the aluminum foil blanket enhances the comprehensive performance of the structure, obviously weakens the convection of the gas, hinders the loss of heat and reduces the energy consumption.
