Basic requirements for design of ceramic fiber lining for refinery flame reheating furnace-6
● The anchorage fasteners in the ceramic fiber module should be at least TP304 stainless steel.
● When the sulfur content in the fuel exceeds 10 ppm, when the ceramic fiber structure is used, the inner side of the furnace panel should be coated with protective coating to prevent corrosion. The protective coating should be applied to the temperature at 177 C.
● When the sulfur content in the fuel exceeds 500 ppm, the TP304 type stainless steel foil should be set up. The gas barrier should be located at at least 56 degrees above the dew point temperature under various operating conditions. The edge of the gas barrier should be overlapped, and the edge and puncture area should be sealed.
